Solar Services. 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.

Our Customers Say

Huge fan of these guys! Super honest and very knowledgeable. I had a few different estimates from different solar companies and felt pressured into a sale. With Old Line I felt no pressure. They even worked with our insurance and got us a free roof before they installed the Solar! The crew was friendly, professional and answered all my questions. I’ve been saving more than half on my electrical bill. I can’t wait for the long summer days to save even more. I highly recommend them!
