Sunlight hits the silicon cells in your solar panels, kicking electrons into action. Those moving electrons create a flow of direct current (DC) electricity, which is converted to alternating current (AC) by the inverter and powers your home. . At a high level, solar panels are made up of solar cells, which absorb sunlight. " Because most appliances don't use DC electricity, devices called inverters then convert it to. . This guide breaks down the science and steps behind solar power: how electricity is generated from solar energy, also captured, and converted into usable power, and how everyday families are turning roofs into mini power plants. You can join them to illuminate the future of energy. How Is Solar. . Solar technologies convert sunlight into electrical energy either through photovoltaic (PV) panels or through mirrors that concentrate solar radiation.

Solar panels work by converting sunlight into electricity using photovoltaic cells. When it rains, the water droplets in the air can scatter and absorb the sunlight, reducing the intensity of the light reaching the solar panels. I often explain this process to help people grasp why weather factors like rain matter. Naturally, weather conditions such as clouds, rain, and snow can significantly impact how much energy your system produces. While solar energy thrives in bright, sunny environments, that doesn't mean it. . Snow can accumulate on solar panels during cold weather, blocking sunlight and reducing the amount of energy produced.
