I have a friend who went to India last year and he related to me of one town (sorry, I did not catch the name) that subsists on solar power. Maybe because the town is situated in a remote area and far from the main power grid. However, the electricity produced by the solar panels are good only for lighting and a little appliance like electric fan. That is already a vast improvement than not having power at all. Such type of power would make us inconvenient because here in the city, we are used to having full power from the electricity provider. I know that solar panel cannot run an air conditioner and that is already a big issue in tropical countries like the Philippines.
