Solar panel systems work very simply: During the day, solar cells in your solar panels absorb the energy from sunlight; Circuits within the cells collect that energy and turn it into direct current (DC) energy; The DC electricity is passed through a device called an inverter to convert it to the usable alternating current (AC) electricity that comes out of your wall outlets; All of which means you can use that electricity in your home, store it with a solar battery, or send it back to the grid. solar suppliers: Xufeng Solar Co., LtdSolar Panel price website:http://www.nbnewsolar.com/small-solar-panels/solar-panel/
