What Is Solar Energy and How Does It Work?

Many business owners know of solar energy but may not fully understand how it can work for them and their business. Solar energy captures power from the sun and converts it into electricity using photovoltaic (PV) panels. When installed on your rooftop, property, or parking structure, these panels generate renewable power to meet your business’s needs. You can use this energy immediately, store it in batteries, or send it back to the grid for credits. It’s a highly effective, sustainable way to lower costs, reduce risk, and power your business’s future.
