What Homeowner Reviews Say

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

Tesla offers a range of sleekly designed solar panels that blend into your existing roof. Its transparent pricing and detailed website make it a valuable choice for customers looking to learn more about solar panels without needing to speak to a sales representative.

What Homeowner Reviews Say

Customer reviews on Best Company report that the Tesla system looks and performs as well or even better than expected. Customer complaints highlight slow turnaround times and trouble reaching customer support.

“I finally went with the Tesla Solar Roof (tiles not panels), and I couldn’t be happier. I needed a new roof anyway so decided to get it with two PowerWall backup batteries. The product looks amazing and [in my opinion] is the best looking solar product on the market right now.” —Robin via Best Company in May 2022

“The price that Tesla offered was great, and the installation went smoothly, but everything else has been a nightmare. No communications from my project advisor during the initial design phase; I had to call Tesla numerous times to ask questions. Once installed, it took Tesla four times over seven months to file the application to the utility company correctly.” —Timothy via Best Company in December 2022

“We leased our solar power system from Solar City before the buyout from Tesla Solar. Transparent transfer from one company to the other. Excellent transaction throughout with great communication from install through activation. We had to deal with our local power company for the connection and turn-on but that was very smooth with assistance from Tesla.” —Ronald via Best Company in May 2021

Our Recommendation

Solar customers in Maryland have an advantage. With so many solar company options available in the state, you can afford to be particular. We recommend the Maryland solar companies SunPower and Sunrun due to their panel performance, warranties, years of experience, and reputation. Before committing to any company, take a look at its warranty, customer reviews, and panel selection. We also suggest getting a free quote from at least three companies to compare pricing before starting your solar project.


What Solar Installation Looks Like

Solar energy companies follow a similar process when getting you set up with solar. 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 any debris and leave your property in good condition.
  5. City inspection: Your provider should coordinate with your city to have an inspector come out to check that your system is up to code.
  6. Utility connection: Lastly, 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 also want to inspect your system to make sure it’s in accordance with its utility guidelines. After getting permission to operate, your system can be turned on.
