What Are Solar Cells? Solar cells, also known as photovoltaic cells, convert light energy directly into electrical energy. They are made primarily from semiconductor materials, with silicon being the most common. When sunlight strikes the surface of a solar cell, it excites electrons in the semiconductor material, creating an electric current.
The energy meter SMA Energy Meter (EMETER-US-50) measures the flow of energy out of and into the utility grid.
