For San Antonio residents who rent, live under heavy tree cover, or have roofs that are not well-suited for solar panels, going solar is still possible.

The utility CPS Energy is now expanding its community solar program, allowing customers to buy panels installed at shared sites across the region and receive bill credits for the electricity those panels produce, according to the San Antonio Report.

Here's what to know

For the program's rollout, CPS Energy is working with Big Sun Solar, a San Antonio-based firm focused on commercial projects across Texas.

Participation is open to anyone with a CPS Energy account, though Big Sun Solar CEO and co-founder Robert Miggins explained that the program is primarily designed for residential users, per the Report.

With shared arrays, customers may be able to buy enough panels to meet all their power needs.

Owners buy and maintain control over any 620-watt panels they purchase and can either move them or resell them to interested buyers. Miggins told the Report that each panel is priced at $1,240, with estimated savings of about $115 a year on electricity bills. Over the program's 20-year life, that amounts to roughly $2,300 in savings per panel.

The first installations will use roof space leased from the San Antonio Food Bank. After that, Big Sun Solar plans to add more facilities on leased Bexar County land with strong sunlight, per the Report.

But for homeowners who can install their own systems, going solar is one of the best ways to save money on home energy. It may be worth exploring EnergySage to get free solar installation estimates and compare quotes. Those who do can save up to $10,000 on rooftop installations.
