Why Solar?

If you live in the United States, you probably pay electricity bills to a utility company that serves you power for whatever the state allows them to charge. Utility companies aren’t exactly known for charging as little as possible. Buying solar panels for home use is like pre-paying your electric bill for 25 years (the length of a solar panel warranty). But no matter where you install solar panels, the cost will be far cheaper than paying for 25 years of electricity.
