Solar energy information for students

How does solar energy work for students?

When the sun is at its highest point in the sky, the sun shines from the south side. Once the sun hits the panels, the energy is made into electricity. A solar inverter helps turn the electricity into power that can be used. The more panels you have on a roof, the more solar electricity you produce!
