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.
