According to reports, the Indian state of Kerala has launched a subsidy program for off-grid rooftop solar photovoltaic (PV) plants for 2012-2013.
Under the Solar Rooftop Power Plants program the state will provide INR 39,000 (USD 720) per 1 KW system, and anticipates an additional central government subsidy of INR 81,000 (USD 1,500) per system. The program will be limited to 10,000 1 KW systems, for a total of 10 MW of PV capacity.
