Family With Solar Panels

What is a Solar Host?

What does it mean to be a solar host? Much like private ownership of solar systems, a homeowner or business would “host” a solar system on their roof. The difference with SolarHosting is that the homeowner or business owner, YOU, would not pay anything at all to have the system installed and maintained.

This means that you don’t have to afford solar in order to see the benefits of the solar generation. It also means that as a CPS Energy customer, you would be doing your part to help the community meet our Renewable Energy Goals. That means that CPS Energy won’t have to build another traditional power plant. Instead, your rooftop along with all of the other hosts’ will be the power plant. Pretty cool right!?

Frequently Asked Questions

Please click on a toggle below, to expand and view the answer for the question.

How much does it cost?

Nothing, in fact you will receive a $0.03 credit from CPS Energy on your bill for every kilowatt-hour that your panels generate!

I heard about this rooftop solar program. How does it work?

You’ll let the CPS Energy partner, PowerFin, know that you’re interested by filling out your information in the form on this website.  PowerFin will do a desktop review to figure out if your house is a good candidate for solar.

The review process will be on a rolling basis as hosts apply to the program. Once your home is evaluated, PowerFin will contact you to let you know if your home is a good candidate. If it is, the rest of the review process should take about 3 – 4 weeks to determine if you’ve been selected as a Solar Host.

After that, it will take about 4 – 5 weeks to get the proper permits and then 3-4 days to install the system on your roof.  Once everything is installed and approved, you’ll start generating electricity which will be sold to CPS Energy for use by the community. In exchange, each month you’ll receive a credit from CPS on your electric bill of $0.03 for every kilowatt-hour that your panels generate.

How can I know if my roof is eligible for the program?

Each roof will be evaluated by the PowerFin team. The initial review will be done using satellite imagery to assess roof orientation and shading. If the initial factors look good, then a PowerFin representative will contact you to set up an on-site evaluation.

What are the benefits to me?

There are a couple of benefits to you as the Solar Host. First, you will see a credit on your bill for the electricity that the panels on your roof generate. That means a lower monthly bill for you. In addition, by being a host, you are helping CPS Energy and our City meet important renewable energy goals that keep our city running for generations to come!

Are rental properties allowed to be part of the program?

Yes, rental properties are allowed in the program. The landlord/property owner must submit the application, support the program and understand that the HostCredit will go to the CPS account holder for the property hosting the system. At this time we cannot transfer the HostCredit to a different property.

What happens if there are problems with the panels after they are installed? Who is responsible for maintenance?

Powerfin is responsible for all the maintenance and upkeep for the system. You don’t have to lift a finger, PowerFin will take care of everything.

Can my Homeowner Association (HOA) prohibit me from having solar panels?

HOAs cannot block homeowners from installing solar panels and thanks to HB 362 and Senate Bill 1626, passed by the Texas Legislature, it is now easier for homeowners to choose to have solar panels on their homes without resistance from their HOAs. According to the law, any, even in the developmental stages of the neighborhood, may elect to have solar panels on their roof. That said, you still need to contact your HOA to let them know you plan to have solar panels installed on your home. Solar Host will be glad to provide any documents needed for your HOA.

How much of a credit will I get on my bill?

It depends on how many panels you have and how much energy they produce. You’re paid $0.03 for each kilowatt hour that your panels generate. An average home solar system would be sized at 4kW or about 16 solar modules. In the summer months when the solar system generates the most, and electric bills tend to be higher, the customer could expect to receive a credit of approximately $20 on their monthly bill.

How long will it take to get it going?

We expect strong demand for this program and we will conduct due diligence on a first come, first served basis.  Once we examine your pre-enrollment application, you should expect 3-4 weeks to move through the evaluation process. This depends on when the on-site evaluation can be scheduled. If you are selected as a SolarHost candidate, the permitting and approval process for the rooftop solar system should take about 5 – 6 weeks. (8-10 weeks total time)

Is this a low income program?

The SolarHost Program is a great fit for all home and business owners since there are no upfront costs.

How is this different from the community solar program announced recently?

With community solar, you have no panels on your roof. Instead, you buy “shares” in a solar farm that are treated like a stock. You own them outright and sell the energy they produce to the project operator, CEC, who then sells it to CPS Energy for use by the entire community in exchange for credits on your bill. The more panels or “shares” you own, the more electricity you generate, the higher your bill credit.

How long do the panels stay on my roof?

Most solar panels have a 25 year warranty, and if you are approved for the SolarHost San Antonio program, we will install panels that will stay on your roof for a period of 20 years. You will receive a solar host credit each month on your CPS Energy bills for 20 years. At the end of 20 years, we will remove the equipment and return your roof to its original condition.

What happens if I sell my home?

If you sell your home, the new homeowner will be enrolled as a solar host and will receive the host credit on their monthly CPS Energy bills for the remainder of the program.
