We just had our Tesla solar panels installed and I want to give a big shout out to the Apollo crew! They were very professional and highly attentive to details. They even painted our conduit to match our house! Both Luc and Minh took time to educate us on our equipment as well as how best to maximum our energy with every day usage. Again a great big thank you to this team!! I am ready to start reaping the reward of solar energy!!

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.

I live in a high demand home market where first time buyers get bullied out by cash offering investors. We found a place that had a sunrun system we inherited. It has always been pricey we use half the power the old owners due sunrun said before we purchased we would be assessed at a year for usage and may reduce the system to save us money if we always overproduce. A year later that was a lie no such assessment and we absolutely use less energy as we have an excess of 450-750 kWh a month. Last year sdge (utility) called me and asked why our power spiked out of control and asked us to check our pv to see if it was working. One of the inverters had died and the system is at half production. I called sunrun which is BS since they allegedly monitor the systems and they tested it over the phone and saw the system had failed. The person told me I’d receive a credit for under production and someone would be out in a month to fix it. A month later the tech was no show, I call and they reschedule a month later. That same call they tell me no such credit applies because i have a over production average. They average the monthly production over the term served in the agreement which we were in year 4-5. So the average was high from overproduction averaged over time since before we even owned the house. Next month comes tech was no show, called again rescheduled for the next month rep told me there was no appt for that month but doubled back when I gave them the date and they investigated. A month later they called same day of appt after a no show to reschedule a month later. A month later the tech bills sunrun for an hour of work after he called me saying he couldn’t do the repair because they never gave him the inverter. So here we are in the 6th month of half production with no current appointment for repair, paying 404$ a month to sunrun, a payment plan for our utility for 143$ because of the energy we used since our panels failed, plus another charge for the electricity we are still using. So we pay about $7-800 for electricity a month for a 2 bedroom home with mostly HE, or gas appliances. The year and a half before the inverter failed we never paid the utility for power and actually had a overproduction. This should be illegal if you get solar go with someone else, if you want a house with a sunrun system tell the owners good luck and go with a different home. If it’s not soon I will be paying a lawyer to review my agreement and the treatment we received. It would probably cost us less then what we currently pay for power.

My solar is a perfect fit for me as I am a senior citizen with no way of paying the cost of putting solar by my self and getting the full benefits before I have passed. Hopefully my true up bill will be very small or $0 as it has been for the last year and a quarter. Thank you

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

Exact cost, savings and payback tailored for your homes location, roof and power use
Industry partners
How do solar panels work?
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.
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.
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

How are solar panels made?
Solar panels are made with a few key materials: solar cells, silicon, metal, and glass. Each layer is built with precision to generate renewable energy.
