I had a 3 kW off-grid system. SSE offered to convert to on-grid with net metering. Earlier, I had to pay electricity bills of around 1000 Rs. average monthly although I was using off-grid solar system. After converting to on-grid and installing a net meter my bills are reduced to a mere 200 Rs. per month and I have so little maintenance to worry about. Earlier it was either the battery, or the off-grid inverter, or some fuse that would disrupt the continuity, now due to the simplicity of the system, I get a seamless performance. I generate almost 450 units every month. Thanks to Shaktisteller, now I own a power plant.
