Solar panels generate enough power to keep a house running, but how exactly do solar panels work? It certainly isn’t magic, although the effects might seem that way. Solar panels absorb and convert sunlight into electricity without all of the harmful emissions that other power sources can create.
Solar cells and photovoltaic cells are important components that make up solar panel systems.
A basic unit of a solar panel is called a solar cell, which usually consists of one or two layers of silicon-based semiconductor wafers. When the photons in sunlight strike these wafers, the solar cell generates an electrical charge. This is called a photovoltaic effect, meaning that these cells are also considered to be photovoltaic cells. The electrons then move from one cell to another in a steady flow.
Photovoltaic (PV) Cells
There are dozens of photovoltaic (PV) cells wrapped up together in a solar module, which are then packaged into solar panels that are mounted on rooftops and set up in the ideal alignment to maximize their exposure and time in the sunlight.
The electricity generated from these cells is a direct current (DC), which is then sent to an inverter that transforms the power into alternating current (AC) electricity, which is fed your subpanel where it can now power your appliances, devices, and your home. Any excess electricity that is produced is then sent into the local utility electricity distribution grid.
