How is it different from pure solar solution?

Even with the reduced cost of installed Solar PV per watt today (which is roughly Rs. 350/- per watt) an Energy-XS small wind system is still cheaper at one fourth that of solar PV on per watt basis. We use this price difference to engineer more reliable systems at greatly reduced prices as indicated above. Additional cost reduction happens as a result of the reduced battery backup needed in a Solar / Wind solution as against a pure solar or wind only solution.
