if your build it yourself solar system will cost you
By working out a dollar amount in this way you will be able to reasonably estimate how your investment will pay off. For example if your build it yourself solar system will cost you around $200 to construct and install, and your savings have been estimated at around $100 a month, then your new solar energy panels will save you $1,000 in your first year!

The majority of households currently purely rely on the main power gird for the supply of electricity.

Do you have a backup source of electricity that you can use to run the essential appliances and heat your water?
