Together, We Produce Energy : Each appliance you use operates on a rate of energy version called a watt (W). For example, a typical computer and monitor uses 270W, a dishwasher with dry cycle 1000W, and a microwave 1500W. Solar energy systems produce power in kilowatts (1 KW is equivalent to 1000 W), and the power they can produce is significant and enough to power much, if not all, of your household energy needs.
