How Much do Solar Panels Save In 2024?

The table below shows our state-by-state solar savings estimates over 25 years. We chose 25 years as the solar lifetime because most solar panel companies cover their products under warranty for 25 years. However, most solar energy systems will last more than 30 years, so you can expect even more substantial long-term savings.
