A solar farm is a large collection of solar panels that convert sunlight into electricity. The electricity is sent to the power grid for use by homes and businesses. Solar farms provide renewable energy that helps replace fossil fuels, reducing greenhouse gas emissions.
The panels at solar farms are usually mounted on the ground, unlike rooftop solar panels on buildings. Solar farms come in various sizes, from small community solar farms to large utility-scale ones. As solar costs have declined 89% from 2010-2020, solar farms have grown rapidly in number and size.
When sunlight hits the solar panels, it is absorbed and converted into electricity by semiconductors in the panels. This electricity is sent to the local power grid through transmission lines. It then travels through the grid to reach homes and businesses signed up to receive solar power. Customers can opt into solar farm energy programs through their utility company or a community solar farm.
Compared to other energy production methods, solar power has minimal environmental impact. Solar energy is renewable and the fuel (sunlight) is free. While installation and maintenance costs are considerable, solar power reduces expenses over time and cuts greenhouse gas emissions by decreasing reliance on fossil fuels like coal and oil. With solar technology improving, solar farms can provide clean, sustainable energy far into the future.
