The first step in configuring your solar system is to define your load. There are two aspects you need to know: power and energy. To determine the power requirements look up the "Power Rating" on the appliances you wish to run simultaneously. Next, determine how many hours per day these loads will run.

You can also check your existing electric bill for "Kwh per month" consumption. This will tell you how many Kwh of energy you`ll need each month.
