We read customer reviews on Trustpilot to see what SunPower homeowners have to say about their experiences. Overall, the company has 2.8 out of 5 stars from over 300 reviews. Here’s a sample:

“Thank you for your prompt service! Your technician was very knowledgeable! We are happy with our service.” —Talia via Trustpilot on May 22, 2023

“Project management has been abysmal. Long delays between various planning and scheduling steps, with no explanation—and usually the project manager was not aware of the problems until we told him/her (there were two different project managers during this time). They were not following up to see if plans were filed with local building offices, or following up to see when permits were ready or inspections scheduled or not.” —Dan via Trustpilot on April 25, 2023

“My solar has been so fun to watch. Peter, the installer that turned on my solar, was able to give me a great orientation to how the solar unit works. He broke things down in a way I could understand. He also gave me some new solar-powered home advice and challenged me to try playing around with my solar storage to see how effective the solar is. I definitely love my system.” —Marian via Trustpilot on January 24, 2023

What We Like

Sunrun’s BuilderChoice New Homes Program ensures its installations meet code compliance. Through this program, customers have a dedicated team handling the paperwork required by local utility companies and other organizations to complete their solar project. We also like that the provider’s 25-year workmanship and product warranty includes free equipment replacement and repair for 10 years.

What Homeowner Reviews Say

Though Sunrun has an A+ rating with the BBB, customers are split on the company’s customer service. Some report that service exceeded their expectations, while others cite challenges regarding communication, responsiveness, and timeliness.

“I felt very informed and comfortable signing contracts. The workmanship was timely and professional. I am waiting for the energy company to do final inspection and start up. I have had several questions which were answered quickly because rep knows about state laws. I am totally satisfied, actually more than satisfied with Sunrun.” —Barbara via Trustpilot on March 27 2023

“We assumed a lease from a previous homeowner and have had numerous issues over the last four years. The panels didn’t work for 11 months. We’ve had roof leaks. The support reps don’t call/text back after they’ve been assigned to your case and I’ve been unable to schedule appointments. Meanwhile, no one else at the company is “able” to schedule an appointment beyond the rep assigned to my case (who won’t call back). The technicians haven’t shown up when they’re supposed to show (without giving any updates).” —Mike via Trustpilot on May 10 2023

“Best customer service I’ve had with any contractor in my life! I don’t believe some of the other reviews I have seen on here based on my experience.” —Curtis via Trustpilot on May 25 2023

What Homeowner Reviews Say

Best Company’s customer reviews mention Palmetto’s professionalism and customer support throughout the solar process. Negative reviews cite slow panel activation timelines, though this could be due to local ordinances.

“The whole experience, from the salesperson to the installation team, was outstanding. Usually, in my experience, once the sale is done, there’s not much communication. With Palmetto, that was not the case. The communication continued throughout making sure all my needs and questions were addressed. Everyone we encountered was professional, friendly, honest, and went out of their way to keep us informed and provide us with very helpful information that one does not normally get.” —Guy via Best Company in February 2022

“Received panels over a month ago still not in service.” —Rhonda via Best Company in February 2022

“Palmetto installed my solar system in June 2021, and it has produced more energy than what I use daily. They have excellent customer support, and their app is very good.” —Josie via Best Company in December 2021

What We Like

Momentum Solar has a long-standing, positive reputation in the solar industry. Its customer reviews on Better Business Bureau and Google Reviews are generally favorable. We appreciate that it intentionally limits its service area to states with established net-metering programs and other solar tax incentives and rebates. A smaller service area also ensures adequate support for each customer.

What Homeowner Reviews Say

Customer reviews on Trustpilot and Consumer Affairs are mostly favorable, pointing to high solar panel performance and reduced electricity bills. The most common complaint is receiving telemarketing calls after requesting information, though it looks like this issue has been resolved. The other primary complaint is no-show appointments.

“They installed my solar panels a year ago and I have never experienced any challenges with the system. Thanks to Momentum Solar, I have forgotten about power bills.” —Felicia via Consumer Affairs on January 28, 2023

“Scheduled 3 appointments and no one showed or called. Tried to contact them and had long hold time.” —Eric via Trustpilot on June 13, 2022

“Been using Momentum Solar for 5-years now and they have never disappointed me. They installed solar, cleaned up the yard, and guaranteed me that the structural integrity of my roof was intact. They are good. I will be using their services again for a holiday home I recently bought.” —Megan via Consumer Affairs on January 13, 2023

Our Recommendation

San Antonio‘s year-round sunny weather, solar incentives, and long list of solar companies to choose from make it a great city for switching to solar energy and reducing electricity bills. Out of all the companies available in the area, we recommend SunPower and Sunrun due to their panel performance, warranties, years of experience, and reputation.

Before committing to any company, look at its panel selection, warranties, and customer reviews. We suggest getting a free quote from at least three companies to compare pricing before starting your solar project.



What Solar Installation Looks Like

Most solar energy companies follow a similar installation process. This typically includes the following steps:

  1. Site evaluation: A company representative will come to your home to evaluate the scope of work and inspect your roof, attic, and electrical setup.
  2. Permit approval: Most states require a permit to install solar panels. Your solar provider should handle this paperwork with your local municipality.
  3. Installation: Installation typically takes one to three days. You don’t need to be home for it, but we recommend it so you can ask questions along the way.
  4. Cleanup: Installers should remove debris and leave your property in good condition.
  5. City inspection: Your provider should coordinate with your city to have an inspector check that your system is up to code.
  6. Utility connection: Your system must be connected to your local utility system if you’re connecting it to the grid. You’ll apply for connection through your power company (some providers do this for you), which will want to inspect your system to make sure it’s in accordance with its utility guidelines. You can turn your system on after getting permission to operate.

How We Chose the Top Solar Companies

We researched and analyzed dozens of solar panels and solar installation companies. We then formulated a rating system based on each solar installer or manufacturer’s services and products. We weighed several significant factors, including the quality and type of solar panels offered, the customer support network, warranty lengths and limitations, and additional benefits such as mobile apps for monitoring and customer service.

Speaking directly to representatives, we determined how each solar company personalizes its solar panel installation for each home. We also analyzed each company’s warranty options to ensure their product and performance guarantees match or exceed industry standards.

We evaluated each provider based on its rating and history with the Better Business Bureau (BBB) to determine reputation. In addition, we analyzed the 100 most recent Google Reviews for each provider across various locations and branches.
