Deutche Bank Bullish on China Solar - Suntech, RenaSola, Trina, Yingli
Deutsche Bank Remains Bullish on China Solar Energy Sector: Upgrades Suntech Power (STP) to Buy
9:41 am ET 10/19/2010 - StreetInsider
Deutsche Bank upgrades Suntech Power (NYSE: STP) from Hold to Buy. Deutsche analyst says, "We expect the leading China solar PV manufacturers to report strong sets of results in 3Q10E and 4Q10E, and believe this momentum should be further extended beyond 2010 due to a more stable module ASP outlook in 1Q11 qoq. Module ASP may start to drop in 2Q11E but we think this risk is likely to be overcome by the ongoing effort to reduce manufacturing costs. The sector trades at an inexpensive valuation of 5-7x 2011E P/E; we reiterate Buy on ReneSola (NYSE: SOL), Trina (NYSE: TSL) and Yingli (NYSE: YGE), and upgrade Suntech to Buy." "We remain bullish on ReneSola despite the 66% increase in share price in the past three months. We reiterate Buy on Trina mainly on its manufacturing cost leadership. We also like Yingli but see possible near-term pressure on 3Q10E gross margins due to the additional ramp-up cost from its polysilicon facility and new production lines. We upgrade Suntech as we believe the stock now offers an attractive risk-adjusted reward return after a year of share underperformance and expect the company to secure new wafer capacity in the near term."

Barclays on Clean Technology: SPI Preview - Case for Multiple Expansion
Barclays analyst says, "Solar companies will be hosting investor meetings at the Solar Power International conference in LA next month (Oct 12-14). We maintain positive bias on stocks heading into the conference. Although stocks have bounced off the May lows, several stocks are still down year to date and are trading at single digit multiples on conservative street estimates. Solar sector performance has historically been strong during the seasonally stronger period for industry fundamentals. We expect this trend to continue in 2010. We see an increasingly stronger case for multiple expansion as the upcycle extends into 2011 and street estimates edge higher. Trina Solar (NYSE: TSL), RenaSola (NYSE: SOL) remain our top picks."

why Ontario should care about Prop 23
Clean Break » Blog Archive » Guest Post: Ontario Eco Commissioner Gord Miller on California’s Prop 23 and why Ontario should care
OK, so what do the vagaries and uncertainties surrounding an election in California have to do with Ontario? Simple. Both Ontario and California are key members of the Western Climate Initiative (WCI), a collaboration of seven US states and four Canadian provinces.
WCI’s goal is to reduce greenhouse gas (GHG) emissions 15 per cent below 2005 levels by 2020 through a number of initiatives, the most important of which is a cap-and-trade system. Currently, two U.S. states (California and New Mexico) and three Canadian provinces (Ontario, Quebec and British Columbia) have passed the necessary enabling legislation required for the development of a cap-and-trade program. But, while Ontario has its enabling legislation in place (see Pricing Carbon: Can a Cap-and-Trade System Deliver the Tonnes from the ECO’s latest Annual Report) it has yet to publicly announce the specific design elements of its cap-and-trade program. It must do this through public consultation and the posting of its final decision on the Environmental Registry.
Losing California would be a major blow to the WCI and possibly to carbon trading systems elsewhere in North America, such as the Regional Greenhouse Gas Initiative and the Midwestern Greenhouse Gas Accord, and quite possibly to the developing international carbon market. Why? Because as California goes, so goes the rest of the U.S., the second largest carbon emitter after China and the third-largest emitter of GHGs on a per capital basis (just behind Australia and, yes, Canada). Without California’s leadership, the development of a North American-wide effort to put a price on carbon would likely be delayed for years.
As shown in the first chart below, California’s GHG emissions represent just over half of those WCI members ready to launch the trading system in January 2012, with a total of just under 480 million tonnes (Mt) of GHGs. Adding New Mexico brings the U.S. tally to almost two-thirds of the five jurisdictions’ emissions. Ontario is the next largest emitter at 190 Mt. Elections will also be held in New Mexico on November 2 and indications are it may withdraw from the WCI cap-and-trade provisions, too.

The panel of expert witnesses advised the Committee that if the United States wants to be a leader in clean energy, it needs to foster innovation by extending successful programs like tax credits, loan guarantees and grants, and adopt a renewable energy standard (RES). Tom Carbone, Chief Executive Officer of Nordic Windpower, said firms like his need clear market signals, such as a price on carbon or a RES, so they can respond to market demand.
Michael Liebreich, Chief Executive of Bloomberg New Energy Finance, emphasized the importance of market signals. Under an RES, the government would require that a certain percentage of utilities’ power plant capacity or generation come from renewable sources by a given date, and mechanisms such as credit trading would allow flexibility in meeting this requirement. However, the RES needs both to be ambitious and to have stiff penalties for noncompliance in order to be successful. Such a policy solution could help create the market demand clean energy firms need to establish footholds and ultimately achieve significant, self-reinforcing growth.

The Solar Module Market: Concerns Ahead « TechPulse 360
The Solar Module Market: Concerns Ahead « TechPulse 360
Sales in other European countries, Italy, Spain and the Czech Republic, are moving ahead in advance of tariff cuts of their own. This is leading prices to be stable and wafer prices to even climb a bit. According to Y. Edwin Mok, an analyst at Needham & Co., crystalline cell pricing has risen to $1.35 a watt, compared with $1.25 a watt or so in the first quarter.
This could help vendors such as SunPower, JA Solar and Suntech Power Holdings.
The danger is that this year’s strength will turn into next year’s softness. The fear is especially high in Italy and Spain, which are facing large tariff cuts, says Mok. German installations could decline as well, he adds.
Mok is not alone in his assessment. John Hardy at Gleacher & Company said he expects the world’s largest module maker, First Solar, to post better-than-expected second-quarter sales later this month and speak favorably about the rest of the year.
“The big industry test is coming” in the first quarter of 2011, he says. That’s when sales could slump and another rapid decline in prices could spark worries of another 2009.

Can SolarReserve Top BrightSource? « TechPulse 360
Can SolarReserve Top BrightSource? « TechPulse 360
SolarReserve is one of the few next-generation solar-thermal vendors with field experience.
The company has the exclusive rights to the molten-salt technology United Technologies’ Pratt &Whitney RocketDyne tested at Solar Two in the California desert during the 1990s.
“We consider that to be a strong competitive advantage,” says Tom Georgis, vice president of development.
It also is a critical reason why the Santa Monica company believes its plants will match or top the efficiency of BrightSource’s Ivanpah. And the experience is at the foundation of SolarReserve’s belief it will find financing, despite the reluctance of private lenders.
SolarReserve is among the most promising of a new wave of solar-thermal developers. Instead of replying on parabolic mirrors, like the SEGS operating in the Southwest desert, these entrepreneurs hope to prove technologies just now moving from the drawing board to large scale deployment: ground-mounted heliostats, heat-concentrating towers, high operating temperatures and storage mechanisms, such as molten salt.
The company’s proposed plants (two in the United States and one in Spain) use as many as 17,000 heliostats to reflect sunlight to receivers atop of 653-foot towers. There the sunlight transfers heat to molten salt, warming the sodium and potassium mixture to 1,050 degrees Fahrenheit, after which it is transferred to a storage tank where it loses no more than 1 degree a day. (BrightSource also anticipates more than 1,000-degree temperatures at Ivanpah.) The superheated liquid is channeled to a heat exchanger where it boils water and powers a turbine.
Solar Reserves claims high efficiencies for much of its operations. The transfer of sunlight to heated salt is 88 percent efficient and the storage tank maintains 98 to 99 percent of the thermal efficient of the molten salt. The weak link is the steam generation system: about 39 to 42 percent efficient. Improvements in turbine technology should raise this.
Altogether, a SolarReserve plant will have an efficiency of 18 to 19 percent, says Georgis. This compares favorably to the 18 percent efficiency BrightSource expects at Ivanpah. (The new generation of solar-thermal plant with concentrating towers and heliostats in general should achieve efficiencies of 17 percent to 20 percent, says Electric Power Research Institute Project Manager Cara Libby – well above the 13 to 15 percent of the older trough plants in the Southwest and Spain.)
SolarReserve also expects to rival BrightSource with its capacity factor, a measure of the amount of time a plant can achieve full output.
The California plant, outfitted with a 150-megawatt turbine, is designed to generate peak-period power for PG&E. Running an average of 8.5 hours a day, it should achieve a capacity factor of 34 percent by heating and storing salt in the mornings and using it to deliver power well into the evening.
BrightSource’s 392 megawatt Ivanpah is to have a capacity factor of 30 percent.
SolarReserve’s Nevada plant should do better. It will have a smaller 100-megawatt turbine and operate longer hours, earning a capacity factor of 53 percent. (The longer the operating hours and the smaller the turbine, the higher the capacity factor is likely to go.)
Despite the ability of the SolarReserve facilities to storage energy, the challenge will be finding financing. Without federal loan guarantees, most plants won’t stand a chance. But the company doesn’t appear ready to buy into the theory.
“It is certainly a challenging environment,” agrees Georgis. “But we are confident we will secure financing for our projects.”
SolarReserve has applied for Department of Energy loan guarantees and is quick to defend their role. “Having the DOE loan guarantees makes it easier to finance,” he says. The extensive government due diligence makes private lenders more comfortable and debt cheaper.
That’s why the industry let out a sigh of relief when Abengoa’s Solana plant near Phoenix won $1.45 billion of Energy Department loan guarantees in July – the first granted since BrightSource’s $1.37 billion package in February.
But SolarReserve appears willing to push ahead even without a government award. It hopes to break ground in both California and Nevada by the end of the year.
The company argues that utilities wouldn’t sign power purchase agreements if they didn’t value the power – a key proof-point with banks. It also largely dismisses increasing competition from solar panels.
Panels are easier to finance, quicker to permit and simpler to deploy. They also are less expensive. With the collapse of module pricing last year, panel costs fell to between $3.50 and $5.50 a watt from $6 or more, says Ted Sullivan, senior analyst at Lux Research. Costs of solar thermal remain largely unchanged at $7 to $8 a watt.
Still SolarReserve isn’t deterred. “It’s more competitive now, no question,” concedes Georgis. But “our power plants are not intermittent resources (and) we’re offering competitive pricing.”
So will the new generation of plants be successful? “It’s too early to say,” says Sullivan. “There have been a lot of plans out there, but nothing has been built on that scale.”
With many technologies showing promise, it will be interesting to see who goes first.

Survival Path Seen For Amorphous Thin Film « TechPulse 360
Survival Path Seen For Amorphous Thin Film « TechPulse 360
Equipment supplier Oerlikon, on the other hand, is not balking. O’Brien says he expects the global production capacity of amorphous cells to someday rival that of cadmium telluride, presently the most popular thin-film technology. First Solar, the world’s largest solar producer and the only significant maker of cadmium telluride, has about 18 percent of the global solar market.
Amorphous production capacity from manufacturers, such as Sharp and Konica Minolta, will add up, says O’Brien.
Thin-film advocates, such as Oerlikon, argue that a lot of the expected cost reductions have already been wrung from crystalline-cell manufacturing. Price declines will eventually slow.
This will leave an opening for thin film. It is an opening Oerlikon hopes to capitalize on. The company says the cost of thin-film cells made with its equipment will drop to 70 cents a watt by the end of the year, from $1 at the year’s start and a $1.50 in 2008.
This may not enable them to catch those from First Solar, which early this year reached 81 cents. (First Solar is likely to offer a new benchmark when it releases quarterly earnings next week.) But O’Brien sees competition increasing and says more significant cost reductions are expected next year. He declined to offer a target.
He says Oerlikon was able to avoid Applied Materials’ fate by maintaining a technological advantage. First, the company’s micromorph tandem junction technology is generating module efficiencies of 8.5 to 9 percent, up from the 7 to 8 percent of a single junction cell.

First Solar’s Cautious Sales Outlook, Cost Improvement « TechPulse 360
On a conference call, it said:
*Module manufacturing costs fell to 76 cents a watt, down 5 cents from the first quarter. Annual throughput per line was up 6 percent to 59 megawatts and material costs were lower. The company’s target is to reach 52 cents to 63 cents a watt in 2014.
*Utility-scale projects are expected to increase. First Solar said it anticipates building 500 to 700 megawatts of projects in North America during 2011, up from 175 megawatts this year.
*Demand is expected to exceed supply in 2010. First Solar expects production capacity to be 2.2 gigawatts by 2012, up from 1.4 gigawatts this year. Module conversion efficiency was 11.2 percent in the second quarter compared with 11.1 percent in the first quarter.

Craton Equity Partners (LA)
Cleantech Blog: Craton Barreling Ahead
Being a senior advisor to the firm, I attended last week’s annual meeting of Craton Equity Partners, a cleantech private equity fund manager based in Los Angeles.
While cleantech in its focus, Craton doesn’t take on much technology risk. Rather, Craton generally invests in companies that have largely proven their technologies – or frankly don’t rely much on proprietary technologies – and are already generating substantial revenues, requiring growth capital to build out their business models into sizable scale.
This was illustrated by the stories told by three of Craton’s portfolio companies:
Along with these three presentations by portfolio company CEOs, the Craton senior partners provided their perspective on the state of the cleantech investment markets.
Of note, the Craton partners believe that the collapse of the credit markets over the past few years has yielded good opportunities for its fund to invest equity in companies – some of whom are generating tens of millions of dollars of revenues, and already profitable – that really ought to have been able to secure debt during more normal times, thereby generating attractive risk-return profiles upon which Craton could capitalize. Clearly, Craton was fortunate to have been focused on later-stage private equity opportunities, rather than earlier-stage venture capital opportunities, where the credit crunch has provided no such opening.
The recent addition of Kevin Wall to the Craton team, possessing significant high-level contacts around the world, reflects Craton’s view that many of the best growth and exit possibilities for cleantech in the coming years will occur internationally. This is a sad but entirely legitimate commentary on the state of the U.S. cleantech marketplace: if you want to really do well in cleantech investing in the next several years, you’re going to have to focus a lot of attention overseas.
Consistent with my personal experience, the Craton team noted that the key success factor for their portfolio companies continues to be management quality. Fortunately, they are seeing (as I am) an influx into cleantech of a greater quantity of better talent in the past few years. Of course, this is in part driven by deteriorating economic conditions and opportunities in other sectors of the economy. But, I also sense it’s because many capable people are increasingly drawn to cleantech for other intangible attractions. (I was recently on the phone with an old friend of mine who made a lot of money in real estate and didn’t find it challenging enough – so he’s moving into cleantech. Five years from now, I’m sure this friend of mine will not complain that making money in cleantech wasn’t sufficiently challenging!)
On the whole, it appears that Craton's first fund is doing generally well, and the firm is beginning to prepare for raising its second fund. The question will be whether Craton's good performance on paper (no liquidity events yet) will be able to overcome a very tough fund-raising environment. Given their strong relationships in the California marketplace – where cleantech has the most traction of anywhere in the U.S. – Craton's progress in the coming 12-24 months will be a good barometer of the health of the cleantech investing thesis in the U.S.

- Propel Fuels, which is developing a critical mass of biofuel retailing locations – by leasing space at existing gas stations, installing necessary equipment for biofuels, managing fuel delivery logistics, and retail marketing via co-branding – across California, with a view towards replicating this model in other geographic markets in the U.S.
- Petra Solar, which has standardized a photovoltaic product for installation on power poles, thereby enabling utilities to meet renewable portfolio standard requirements while also improving the quality and management of power throughout their distribution grids.
- GreenWave Reality, which is aiming to extend the smart-grid “beyond the meter” and into the home, via a centralized radio-broadcasting gateway at the service entrance and a variety of intelligence-enabled radio-controlled applications throughout the home to manage energy usage.
Along with these three presentations by portfolio company CEOs, the Craton senior partners provided their perspective on the state of the cleantech investment markets.
Of note, the Craton partners believe that the collapse of the credit markets over the past few years has yielded good opportunities for its fund to invest equity in companies – some of whom are generating tens of millions of dollars of revenues, and already profitable – that really ought to have been able to secure debt during more normal times, thereby generating attractive risk-return profiles upon which Craton could capitalize. Clearly, Craton was fortunate to have been focused on later-stage private equity opportunities, rather than earlier-stage venture capital opportunities, where the credit crunch has provided no such opening.
The recent addition of Kevin Wall to the Craton team, possessing significant high-level contacts around the world, reflects Craton’s view that many of the best growth and exit possibilities for cleantech in the coming years will occur internationally. This is a sad but entirely legitimate commentary on the state of the U.S. cleantech marketplace: if you want to really do well in cleantech investing in the next several years, you’re going to have to focus a lot of attention overseas.
Consistent with my personal experience, the Craton team noted that the key success factor for their portfolio companies continues to be management quality. Fortunately, they are seeing (as I am) an influx into cleantech of a greater quantity of better talent in the past few years. Of course, this is in part driven by deteriorating economic conditions and opportunities in other sectors of the economy. But, I also sense it’s because many capable people are increasingly drawn to cleantech for other intangible attractions. (I was recently on the phone with an old friend of mine who made a lot of money in real estate and didn’t find it challenging enough – so he’s moving into cleantech. Five years from now, I’m sure this friend of mine will not complain that making money in cleantech wasn’t sufficiently challenging!)
On the whole, it appears that Craton's first fund is doing generally well, and the firm is beginning to prepare for raising its second fund. The question will be whether Craton's good performance on paper (no liquidity events yet) will be able to overcome a very tough fund-raising environment. Given their strong relationships in the California marketplace – where cleantech has the most traction of anywhere in the U.S. – Craton's progress in the coming 12-24 months will be a good barometer of the health of the cleantech investing thesis in the U.S.

Since 2007, Ford and Johnson Controls have worked with leading electric utilities and EPRI. In 2007, Ford announced a partnership with Southern California Edison, the electric utility with the nation’s largest and most advanced electric vehicle fleet. The partnership is designed to explore ways to make plug-in hybrids more accessible to consumers, reduce petroleum-related emissions and understand issues related to connectivity between vehicles and the electric grid. For the 3-year study, Ford Escape Plug-in Hybrids have been heavily used. It will not be until 2012, that consumers can order plug-in hybrids from Ford.

Clean Break » Blog Archive » Q-Cells and ATS Automation create Ontario JV to develop 64MW of solar
Q-Cells, one of the world’s largest solar PV providers, has inked a deal with ATS Automation Tooling Systems of Cambridge, Ont., to develop 64 megawatts worth of solar projects in Ontario already conditionally approved as part of the feed-in-tariff program. The two companies have formed a 50-50 joint venture called Ontario Solar PV Fields Inc. that is expected to begin construction in 2011. ATS will use Q-Cells’ PV cells in modules it will manufacture at its Photowatt Ontario facility in Cambridge, allowing the JV to qualify under 60 per cent local content requirements. “The Ontario market is projected to be one of the dominant solar markets in North America in 2011,” said Marc van Gerven, Q-Cells North American chief executive.
As I mentioned in a previous post, ATS is one of more than 10 companies that had annunced intentions to make solar modules in Ontario, adding up to more than 1,000 megawatts annually of local manufacturing capacity. ATS was promoting a dual strategy — producing both its own product as an Ontario extension of its France-based Photowatt business, and making modules for other companies under contract. This JV fits with the latter.

The folks over at Green Energy Reporter are reporting that eSolar’s founding chief executive Asif Ansari has decided to join Toronto-based Morgan Solar as its new CEO. I knew this deal was in the works, and apparently Ansari has been with the company now for a couple of weeks and plans to relocate his family from California to Toronto. It’s a good catch by the Morgan boys, who I’m betting will be making more news over the next couple of years. Ansari tells Green Energy Reporter, “I took a look at Morgan’s technology and I instantly understood that they had developed a game changer.” That’s the feeling I walked away with as well. It’s a great story unfolding.

Japan is appealing Ontario’s Green Energy Act procurement policies to the World Trade Organization, on the basis that the Ontario content requirement violates international trade agreements. Japan’s interest is obvious. It is a major supplier of solar panels, with major brands such as Sanyo, Kyocera and Sharp playing a major role in the world markets. It will be interesting to see the interaction between Canada’s federal government and Ontario on this one. After all, the federal government doesn’t have jurisdiction over electricity procurement.

On Friday we’ll see four more coal-fired units totalling 2,000 megawatts closed in Ontario, part of the government’s commitment to phase out coal by 2014. Two 500 MW units at Lambton station and two 500 MW units at Nanticoke will be shut down ahead of an earlier schedule because of a combination of factors: lower electricity demand, increased natural gas capacity and a rise of wind, and to a lesser extent, solar power. Another plant, the smaller Atikokan station, will be converted to burning biomass.

Sarnia solar power plant and that the facility now ranks as the largest solar PV plant in the world. The plant is owned by gas and pipeline giant Enbridge Inc. — you know, the guys who had the big oil spill in Michigan. The press release says it is an 80-megawatt plant, but over at PRResources.com it ranks the project first at 97 megawatts. Not sure what the deal is there. But even at 80 megawatts it’s still 33 per cent larger than the second-largest plant, which is in Olmedilla, Spain. The next largest in Canada, ranking 24th worldwide, is the 23.4 megawatt facility in Arnprior, Ontario.

Flexible PV modules promise to be integrated into building materials, similar to the way United Solar, a division of Energy Conversion Devices (ENER), laminations have been used in single ply roofing and standing seam metal roofing. When a PV technology can reduce the structural balance of systems (BOS) cost there is an economy for the installation due to the lack of glass and the potential for true building integration. Look for CIGS companies like Miasolé, Global Solar Energy, Ascent Solar (ASTI), and Nuvosun to follow in SoloPower's footsteps in certifying the long-term performance and safety of high efficiency flexible PV modules for building integrated (BIPV) and other flexible applications.

View From the Turret: Crossroads Trading -- Seeking Alpha
Solar Strength
A number of key solar names were sharply higher last week as traders reacted to a few compelling themes:
JA Solar Holdings (JASO) is one of the many solar companies that is seeing a rebound in both revenue and earnings, and analysts have been increasing their expectations for the next two years.
With a stable balance sheet and a PE multiple that is still in the single digits, JASO could continue to rally for some time to come. I’m not interested in chasing the stock at these levels, but a pullback to near $7.50 or $8.00 along with a period of consolidation would have me much more interested in picking up a small position and then adding more exposure as the trend reasserts itself.

Investment Managers Still Lagging in Response to Climate Change
Investment Managers Still Lagging in Response to Climate Change
California State Teacher's Retirement System (CalSTRS) $130 B
"As a long-term investor, CalSTRS wants to invest in well-managed companies that can address the physical risks of climate change and adapt to the changing regulatory and market realities of a carbon-constrained economy," said Jack Ehnes, chief executive officer of CalSTRS, the nation's second largest public pension fund, with more than $130 billion of assets under management. "Our asset managers need to ask the right questions and critically evaluate how companies are positioned so that we’re sure that our investments will produce outstanding risk-adjusted returns for our members."
The survey was done at the request of the Investor Network on Climate Risk, a network of 80-plus pension funds and other institutional investors who rely on asset managers to manage their investment portfolios. Eighty-four asset managers managing $8.6 trillion in assets completed the survey, including 66 in the P&I top 500 list and 18 others who responded at the specific request of INCR client members.
In summary, the survey found only a few asset managers – MFS Investment
Management and F&C Asset Management plc, among those – that are including
climate risks and opportunities throughout their investment analysis – in their
asset allocation, portfolio valuation, and corporate governance due diligence. Like
companies that are rethinking and retooling their business strategies in response to
climate change, these asset manager leaders are positioning themselves to capture
the opportunities and understand and manage the risks of climate change across
their portfolios.
The vast majority of respondents, 84 asset managers managing $8.6 trillion
completed the survey, including 66 in the P&I 500, are in the preliminary stages
of including climate risk in their due diligence.

Mr. Dravis's approach to Cleantech is a good one: look for supporting industries that have less technological risk than the high profile start-ups. He currently likes Cosan (CZZ), SQM (SQM), General Cable (BGC), and Power-One (PWER) almost all of which I've had good things to say about in the past, for similar reasons (see here, here, and here). The only one I have not talked about is SQM, which is not green enough for my taste (admittedly a fairly high bar.) That said, I was more impressed by his feel for market timing than his industry knowledge, so much so that I asked him to send me his weekly newsletter, the Dravis Wealth Advisor, which he does not charge for. If you're interested in giving his newsletter a try, send him an email at p a u l at d r a v i s dot n e t. Like me, he's currently quite bearish, so don't rush out to buy his picks unless you're also prepared to hedge them.

Pacific Gas & Electric Company (PG&E) from San Francisco is in the energy sector for decades. They have produced power from atomic energy, natural gas and water. Now PG&E has gone ahead and collaborated with Manhattan Beach start-up called Solaren Corporation. But what put this deal apart from others? Actually Solaren Corporation aims to launch a series of giant solar collectors into orbit 23,000 miles above Fresno. They will beam the energy to earth in the form of radio waves. Now PG&E has finalized a contract with Solaren to buy the power on one condition if they can make the technology work.

Molten Salt Solar Plant
Molten Salt Solar Plant
A Santa Monica-based energy firm known as SolarReserve in association with a rocket maker in Canoga Park is planning to set up a much larger plant in this desert area to power around 100,000 homes. This power plant will consume molten salt, water, sun’s heat and rocket science to generate electricity. SolarReserve have already patented the technology. Engineers from Rocketdyne are instrumental in developing this technology. Terry Murphy who is the president of SolarReserve says, “Molten salt is the secret sauce.” Many technological ideas are being in various state of readiness to be implemented in California. But analysts found molten salt technology as most unusual and at the same time promising idea. Nathaniel Bullard, a solar energy analyst with New Energy Finance in Alexandria, Va, thinks, “It’s actually something we’ll likely see in a few years. It’s moving along in a nice way, and they have good capital behind it.” Last year the company secured $140 million in venture capital.
The biggest advantage of the molten salt is once cooled, it could be reutilized for the same purpose. The molten salt can be stored for days to generate electricity. We know that storage of power is great problem as far as energy generated from alternative sources. We can store power in a battery on a small scale basis such as car or home. But power for such a large scale can’t be stored in batteries. Murphy elaborates on the solution to power storage, “You can put that (molten salt) into a storage tank that would look much like a tank at an oil refinery. We can store that energy almost indefinitely.”
SolarReserve, is providing funds to the venture and doing the marketing of the project. Many environmentalists groups are voicing concern about the amount of water utilized. But SolarReserve officials are sure that the plant would use one-tenth the amount of water required by a conventional plant.

They are planning to install 1.3 Giga Watts (GW) of solar power and register their city’s name in the book of green economy. The plan was announced by Mayor Antonio Villaraigosa, City Council President Eric Garcetti, Council member Jan Perry and the Los Angeles Department of Water and Power (LADWP). This program is known as Solar LA. They aim to replace the fossil fuels during peak energy requirement and the program lays out a far-reaching and long-lasting course of action for a network of residential, commercial and municipally-owned solar systems to replace fossil fuels during peak energy demand.
The Solar LA plan covers three primary components: first one is the programs to boost residential and commercial customer solar systems; second one will be the LADWP-owned solar projects in Los Angeles; and the third one will be the large-scale solar projects owned by the LADWP outside of the LA basin.

Cash Incentives for Solar Energy in California
Cash Incentives for Solar Energy in California
Assembly Bill 920, authored by Assemblyman Jared Huffman, D-Marin, and signed by the governor of California, requires utilities to pay solar customers who produce more energy than they use.
Currently homeowners that produce more solar energy than they produce can zero their bills but they’re not paid for the extra energy they feed back into the grid. The payment for producing extra energy is known as “feed-in tariffs” and such an incentive has seen great success in European countries like German and Spain.
Under the new law, the California Public Utilities Commission is required to set the rate for the paybacks by Jan. 1, 2011.

Google Plans New Solar Mirror Technology
Google Plans New Solar Mirror Technology
They are developing a new mirror technology for cheaper solar power. Weihl confirms, “Typically what we’re seeing is $2.50 to $4 a watt (for) capital cost. So a 250 megawatt installation would be $600 million to a $1 billion. It’s a lot of money.” That amounts to 12 to 18 cents a kilowatt/hour. They are using solar energy to heat up a substance that produces steam. This steam will turn the wheels of turbines. Mirrors will start the whole process by directing the sun’s rays on the substance to heat it up. Bill Weihl reaffirms his company’s commitment, “We’ve been looking at very unusual materials for the mirrors both for the reflective surface as well as the substrate that the mirror is mounted on.”

PV Cell Prototype Generates Electricity from IR and UV Light
Recently scientists at the Kyoto Institute of Technology have deviated from the normal path and tried to trap the visible as well as invisible rays of sun for electricity. They tried to create a new photovoltaic cell that can capture visible, infrared and ultraviolet light of the sun. The team now thinks that this photovoltaic will be highly efficient for solar power conversion.
These new PV cells were made up of gallium nitride (GaN) semiconductor. This new photovoltaic cell is created by ‘doping’ a wide bandgap transparent composite semiconductor i.e. gallium nitride (GaN) with a 3d transition metal such as manganese. Gallium belongs to the family of scandium, titanium, vanadium, chrome, iron, cobalt, nickel, copper, and zinc. Sonoda explained that his team has gone for those additive elements. He said that even aluminum nitride (AlN), which has a very large bandgap, can possibly have an absorbing region in the visible light range,

Nanosolar: Solar Power at a Lower Cost
Nanosolar: Solar Power at a Lower Cost
The low efficiency which haunted Nanosolar raising the cost of installation of solar-power arrays and which necessitated more solar panels has been addressed successfully by Nanosolar. The larger panels they are now using generate more power; with modifications that cut the cost, the larger panels generate 160 watts as against 70 watts by First Solar.
Power output:
According to Martin Roscheisen, Nanosolar’s CEO, in sunny locations, power plants with these panels could produce electricity at 5-6 cents per kilowatt hour. Mr. Roscheisen claimed even the 16.4 % energy conversion in sunlight as against 20% energy conversion in the lab and only 11% of that energy into electricity by Nanosolar is high enough compared to conventional solar panels.
Not bankable?
But the claimed low costs are attainable only at close-to-capacity operation level which is at best a distant possibility. Because despite all improvements, under the current economic scenario, Nanosolar is finding it tough to find banks willing to back power plants which may be ready to use their solar panels. Now the panels are not yet “bankable;” but Nanosolar is hoping for a better future.

Multi-layer gallium stacks
Sun Shines on Solar Energy Future
Instead of thin single-layer gallium arsenide deposited on small wafers, the Illinois group tried to create ‘pancake’-like stacks of 10 layers deposited at one go and peel the layers off individually, transfer them and lay them side by side. Giving all details of this procedure, Professor Rogers, the Lee J. Flory Founder Chair in Engineering Innovation & Professor of materials science and engineering and of chemistry said, “We’re creating bulk quantities of material, as opposed to just the thin single-layer manner in which it is typically grown…. “You really multiply the area coverage, and by a similar multiplier you reduce the cost, while at the same time eliminating the consumption of the wafer.”

Increasing Solar Conversion with Quantum Dots
Costs for Thermo-photovoltaic Cells Significantly Reduced
Thermo-photovoltaic (TPV) cells are great for converting radiation from any heat source to power. These cells can generate power from the wasted heat which gets released when glass or steel is produced. Adding these TPV cells to domestic power systems can help generate power along with heating water. TPV systems are also too complex for everyday use. Both of these reasons have made the TPV systems beyond industrial and domestic consumer routine set-up.
