Without an inverter, your solar panels produce electricity that your home can't actually use. That's because solar cells generate DC power, while most homes and appliances run on AC. . Solar cells, or photovoltaic (PV) cells, convert sunlight into electricity. In DC, electricity is maintained at. . Another essential component is the inverter, and thanks to technological advancements, there are inverter options. Keep reading as we walk you through what an inverter is, how it works, how different types of inverters stack up, and how to choose which kind of Inverter for your solar project. How exactly is solar current produced? The minute the sun's rays hit the solar cell's surface, electrons start flowing, and once they do, a current is generated. It receives DC electrical energy from solar cells.
