Question by jajeromes: How much solar panel installation cost for a normal home in Tamilnadu, India?
I have been hearing and seeing lot of traction on the use of Solar panel for the power generation to homes. But i am not confident that the power produced from solar energy will be sufficient during the night due to the high costs in installing the solar panel for normal middle class families. As per the reviews in forums by customers i could see there is a lot of maintenance costs involved and to get more power we need to put more panels (like 1KW or more). Please advice and share your thoughts so that i can review and find a best possible solution for the solar panel installation in my home?
