SourceIn this part of the world, having a backup power source is no new thing; it is, in fact, crucial if one must ensure a steady power supply. It was formerly the case that people went for petrol generators; I guess the increase in the price of petrol caused many people to withdraw. Solar has, as a matter of fact, become the best option for many; I too think it far better than the normal power supply and petrol generators. Having experienced these three different electricity sources, I think solar is superior, and I have my reasons.
