Rooftop Solar system can become most effective

Rooftop Solar system can become most effective if optimizes devices consumption and use hybrid charging ( Solar + Grid). This help reduce battery sizing and gives un-interrupted power all the time. We are proposing typical solution for 500 W consumption for 30 devices (mix Street Light, Fan , LED Tube lights) with 2KW solar with 12V/900AH Battery. This Gives more than 12 Hours back up.

Some recent studies have shown that the critical distance beyond which grid extension isn't feasible when compared to solar micro grids is 18-25 kms. This was based on 11kV distribution lines. If the purpose of these plants is to feed into the grid from remote locations, one would expect the delivered cost of electricity to increase with distance from nearest accessible grid. This increase will be lesser as the delivered peak load increases and hence, the excess cost of laying 11kV distribution lines is distributed over larger generated kWhs. So the commercial feasibility will depend on the tolerance level of higher delivered cost of electricity from remote sources (as high as 25-40 Rs/kWh for remote PV) when compared to grid electricity (2-3 Rs/kWh).
