A big selling point for solar power is its positive environmental impact. Solar power is considered a type of green energy, meaning it’s better for the environment than traditional fossil fuels. Because you can use solar power to run nearly any electrical system, including lighting and appliances, it’s an easy and efficient way to reduce your overall carbon footprint.

Another big benefit is that a solar array can help protect you against high electricity bills, as the energy generated by the system can offset reliance on the grid. Some states even allow solar array owners to sell excess solar energy back to the utility through a process called net metering.
