Solar For Homeowners

Convert Your Home to Solar Energy & Start Saving Today

Homeowners can save thousands of dollars by switching to solar power. If you’re a residential homeowner, you know that every year utility companies raise electricity rates. But with high-efficiency solar panels installed on your home, you will have a consistently low electric bill for decades. Take control of your energy future and save money by installing residential solar.

You can own a solar power system for $0 down. It's essentially refinancing your electricity bill to a lower per month payment. Allterra Solar has partnered with local financial institutions to provide low-interest solar loans to our clients. With interest rates as low as 3.99%, now is a great time for homeowners to go solar.

Testimonial From a Happy Solar Owner

An outstanding local company that provides quality reliable installation and service using the best panels in the industry. They will personally evaluate your energy needs to best suit your budget and lifestyle. If your home is not suited for solar, they will not sell you a system just to make a sale. Truly a five star company.

Selling Your Home?

You’re in luck! Department of Energy studies on real estate sales data conclude a home’s value increases from purchasing solar for your home. Homes with solar also tend to sell faster than other homes. Prospective buyers are willing to pay more for a home with solar because homes with solar are less expensive to power. A typical solar project is around 4,000 watts and would present an equity gain of $16,000. Study was based on 26,000 homes sold across 11 States and compared homes with and without solar purchased and installed. (Please note, PPAs may not bring equity to the home since it is not part of the home and owned by a third party.)
