“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

“Great service and easy to use app. From case manager to installation you can expect excellent customer service.” —Isaac via Best Company in January 2023

“My real complaint is service issues reported to service technician timelines. Customer service explains that they are short on service personnel and lag time is about four weeks for a call back let alone how much time from there to on site and repair. This is the second time I needed on-site service, and they delayed.” —Forest via Best Company in December 2022

“Salesman was very knowledgeable with the products. He was prompt in returning messages. Once all panels were fully operational, product works great.” —Christine via Best Company in November 2022

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

Benefits and Drawbacks
Pros Has mobile app that monitors installation process and energy production Offers comprehensive warranty on equipment and installation Works with various manufacturers Cons Doesn’t provide a system output guarantee Doesn’t prioritize in-person home consultations to determine solar suitability Doesn’t sell solar batteries in all locations
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 to Ask Solar Providers

Getting a great return on investment for your solar project starts with picking a quality solar company. We recommend asking solar panel companies these questions:

We also suggest asking these questions about equipment:



Solar Services

Most companies offer certain services throughout the installation process to help you get the system you want and continue to maintain it. Typical services include the following:



Our Recommendation

We recommend any provider on this list, but the right one for you depends on your priorities. For example, if you want a company that has years of experience and has performed thousands of installations, SunPower may be the best fit. If warranty coverage and guaranteed performance are your priority, ADT Solar’s comprehensive coverage may be a better fit.

We recommend reviewing each provider’s website and warranty carefully to understand what it offers, as well as reading customer reviews. We also recommend getting a quote from at least three companies to compare pricing.



What Solar Installation Looks Like

Once your system is designed and approved, most solar energy companies follow these steps to get it installed:

  1. Site evaluation: A representative will come to your home and inspect your roof, attic, and electrical setup, as well as confirm the scope of work needed for your installation. 
  2. Permit approval: Your solar provider should handle any necessary permitting 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 you are so you can ask questions along the way.
  4. Cleanup: Installers should remove any debris and leave your property in good condition.
  5. City inspection: It’s standard that your provider will have a city inspector come out to 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 utility company (some providers do this for you), which will also want to inspect your system to make sure it meets its utility guidelines. Your system will be turned on after you receive permission to operate (PTO). This process can sometimes take a few months.
