The energy use of your home is determined by a few factors, including its size and the
appliances you use.If you are interested in using solar power for your home, the first thing you
should do is to find out how much electricity your home currently uses. Your utility bill can
provide some historical data and help you determine how many solar panels you will need.
Using a yearly average is best because the amount of electricity used does vary from month to
month and with the seasons.
