Leo's crew with Tesla installed a 36-panel solar system and two Powerwalls in a day and a half. All crew members were professional and respectful. Very little was required of me throughout the entire process. The necessary power outage was kept to a minimum amount of time, which made the installation process less inconvenient that I thought it would be. They were quick to answer any questions I had and did an excellent job explaining how the different components of the system work. They also did a good job cleaning up around the exterior of the house before they left, after the installation was complete. I would definitely (and likely will) recommend Tesla Energy to friends and family for their renewable energy needs.

I used this company to have a basis for my solar panels on my new house. They did a great assessment of my usage, roof, and environment. They came to the house after numerous meetings online (COVID) to finalize the project and check if 100% everything was fine. Everything financially was reviewed. Before starting, they took over all the communication with the HOA. Once approved by the HOA, the project was started. I now have 28 beautiful Solar Panels which cover 100% of my yearly usage. Would I recommend Cape Fear Solar Systems: YES.

The Panasonic panels we had installed had better power generation than what the competition wanted to steer us towards, and a much longer warranty.

We have had Sunpower Solar now for a little over a year now and are more then just pleased. We produce much more then we use. In fact we have a nice credit built up with the electric company. So far we haven't had any problems with the system and would recommend Sunpower to anyone.

Trouble with panels. Website rarely works. Customer Service is terrible if you are lucky enough to get through. Placed on hold numerous times. Disconnected numerous time. My roof is leaking. I called over a month ago to have the panels removed. I paid for the service over a month ago. I have called numerous times. They can take your money but fail to provide the service. I would NOT recommend to anyone.

Guides to residential solar panels in your state
All you need to know about solar in your state
The economics of the solar panel installation varies by house, utility area, climate zone, and state. As such we have prepared state-based solar guides. These guides include localized solar panels production data, local rebates, and incentives as well as ballpark cost, savings and estimators that take local weather and utility electric rates in to account.
Try the calculator below:
SolarReviews calculator uses best-in-class technology to give you a professional-level estimate in minutes

How do solar panels work?
Grid-tied solar system
Solar panels are mounted on your roof and wired together in groups called solar arrays. The power they generate flows into a solar inverter, where the direct current (DC) is converted into alternating current (AC). The electricity is then either used by your home or exported to the electric grid.
Off-grid solar system
Off-grid solar power involves meeting all your energy needs from the sun; there’s no utility to fall back on. The solar installation needs to power your home not just during the day, when the sun is shining, but after dark as well. This requires many solar panels, paired with a large battery system.
Hybrid solar system
In hybrid solar systems, rooftop solar panels are connected to both a solar battery and the electric grid. This reduces your reliance on the utility while also providing backup power when needed. Battery storage is still expensive but you may be able to reduce costs by using state incentives.
Information Solar Reviews provides
Can you trust SolarReviews?
Behind the brand
We do everything we can to ensure you can trust the reviews you read on SolarReviews.
No solar company can pay to alter their reviews score, what reviews are displayed, or where their company appears on SolarReviews.
A reviews auditing team ensures that only genuine reviews are published. We use an algorithm developed in-house for this purpose, along with manual spot checks; every review gets vetted.
We have caught hundreds of solar companies trying to write false positive reviews, and repeat offenders are banned from the site. Our measures also safeguard against false negative reviews, where competitors seek to unfairly damage the reputation of another company.
Our Mission
Who we are
SolarReviews is dedicated to ensuring access to unbiased information about solar. We enable you to decide whether solar panels are right for you based on accurate information, not based on pressure from solar salespeople.
We believe that if we put quality, easy-to-understand information on the internet, consumers are less likely to be misled by solar companies — and more likely to be satisfied with their solar system.
Content on our site — both by our journalists and from consumer reviews — have drawn attention to unfair or misleading tactics by solar companies, and helped stamp them out.
For instance, until recently large solar companies issued quotes that omitted equipment details such as brands and models; this allowed them to use cheaper, less reliable brands in their installations. However, as a direct result of our exposure of this issue, this practice is almost gone from the industry.
How do we make money?
How we work
When viewing reviews of solar companies or specific solar equipment on our site, you may decide you want to request a quote.
Approximately 2% of our site visitors make this decision; when you do, we earn a small fee from the solar company you request the quote from. The fee is the same regardless of which solar company in your area you choose for a quote.
For the other 98% of site visitors, we are just a high-quality consumer education website, providing free content and calculators for consumers to evaluate the solar potential of their homes.
Editorial Advisory Committee
SolarReviews has set up an editorial advisory committee as part of a commitment to our quality solar initiative
