How Do Solar Farms Work?
Solar farms turn sunlight into electricity using photovoltaic (PV) cells. These cells are essential for transforming light into power. At the heart of this process are solar panels containing PV cells that absorb sunlight, producing an electric current.
Key components of a solar farm include solar panels, inverters, and mounting systems. Solar panels with PV cells capture sunlight, while inverters convert the DC power generated by the panels into AC power, which is used by most devices in our homes. Mounting systems hold the panels in place, usually in wide-open spaces, to capture as much sunlight as possible.
After the inverters convert the electricity, it flows to the grid, where it can be distributed to homes, businesses, or stored for later use. Sometimes, the power stays local, supplying energy directly to a nearby facility or community.
Solar farms can be either utility-scale or community solar. Utility-scale farms are large and produce significant amounts of power, while community solar farms are smaller and often serve a specific local area.
Every part of a solar farm works together to create clean, renewable energy. This energy helps reduce our reliance on fossil fuels and lower greenhouse gas emissions. By supporting solar farms, you contribute to a greener, more sustainable future.
