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

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

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
Solar Installation Cost Factors in San Antonio
According to EnergySage, the average price for a 5-kilowatt (kW) solar panel system in San Antonio is $13,250. However, several factors impact what your total cost will be, including the following:
- Company: Solar providers charge different prices for their products. If the company you buy your panels from doesn’t manufacture the equipment, the manufacturer will also influence pricing. Better quality and reputation mean a higher price tag.
- Energy efficiency: Expect to pay more for high-efficiency solar panels.
- Panel type: Most solar companies only sell monocrystalline panels due to their high performance, which makes them more expensive. You can opt for more affordable polycrystalline and thin-film panels, but they won’t be as efficient and you may need more of them to power your home.
- Roof pitch: Most solar installation companies charge extra for riskier or more difficult installations. Plan to pay more for labor if your roof has a steep pitch.
- System size: The more panels you have, the more expensive your system will be.
Solar Tax Incentives in San Antonio
Texas offers residents several ways to save money when installing a solar power system. Your solar installer can help you identify which tax credits and rebates you qualify for, but most Texans can take advantage of the following:
- Property tax exemption: Installing solar panels increases your home value, which typically drives up the property tax you owe. However, Texas waives these additional taxes for solar panels.
- Net-metering: CPS Energy will buy back the excess energy your system generates to supply electricity to the local power grid.
- Federal solar tax credit: Those who purchase their solar energy system outright or via solar loan qualify for the federal tax credit. This allows you to claim 30% of your total solar panel cost on your income taxes the year of installation.
- Solar rights law: This isn’t a financial incentive, but Texas has a solar rights law that prevents Homeowners Associations from blocking your solar installation.
Getting Solar Quotes in San Antonio
You can get a quote for your San Antonio solar panel system in just a few minutes by following these steps:
- Go to the website of the company from which you want a quote. Click on “Get a Quote” or similar language either in the top right corner or at the bottom of the home page.
- Fill out the required information. This typically includes basic contact information, property details, and roof size.
- You’ll either receive a free quote on the site or by email within a few minutes.
You can also get a quote by phone if you prefer to speak to a representative. The average time to get a quote by phone when we called providers was 15 minutes.
What to Ask Solar Providers
We recommend asking solar panel companies these questions:
- Are your NABCEP-certified, licensed, bonded, and insured?
- Can you share a few customer references?
- Does your team do all the work, or do you use subcontractors? How do you check the work your subcontractors perform?
- Have you worked with my local utility company?
- How long have you worked in solar?
- How many systems have you installed? May I see photos?
- What is your business license number?
- Who do I contact if I have a question or issue? What are turnaround times like to resolve issues?
We also suggest asking these questions about their equipment:
- Is this what you have/would put on your home or business?
- What are the benefits and drawbacks of this equipment?
- What do customers complain about with this equipment?
- What warranty protection do you offer for each piece of equipment?
Solar Services
Solar panel installation companies often provide a few services to help guide you through the solar process and care for your system after installation. These can include the following:
- Consultation: All companies should offer an initial consultation to discuss your home’s energy needs and whether your property is a good fit for solar. This is done virtually or in person. While virtual consultations are more convenient, be aware that the representative won’t be able to provide as specific or potentially accurate information as they would if they saw your property in person.
- Design: Providers have in-house design teams to create the best solar panel layout for your roof. You’ll approve this design before installation moves forward.
- Installation: Not all companies use an in-house installation team. Some use third-party companies. Some only install panels, while others install batteries, electric vehicle chargers, and other equipment. In-house installation is typically preferred, as it ensures quality and reduces potential communication issues across multiple parties.
- Maintenance and cleaning: Many warranties include a maintenance plan through your provider. Check if a company provides system maintenance or cleaning services after installation.
- System monitoring: If a company has a mobile app, it likely includes some degree of system monitoring. Ask if a provider offers system monitoring to track your panels’ performance.
- Additional services: Some companies partner with third parties to handle services that help your installation run smoothly. Roof repair and pest control are common additional services because installing panels on a damaged or infested roof isn’t wise.
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:
- Site evaluation: A company representative will come to your home to evaluate the scope of work and inspect your roof, attic, and electrical setup.
- Permit approval: Most states require a permit to install solar panels. Your solar provider should handle this paperwork with your local municipality.
- 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.
- Cleanup: Installers should remove debris and leave your property in good condition.
- City inspection: Your provider should coordinate with your city to have an inspector check that your system is up to code.
- 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.
