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.

We inherited the lease when we bought our house. They just lie that you will save money. We ended up paying more and are stuck with them for 20 years! They are charging us 37 cents per kWhs which is much higher than PG&E, and they increase it by 2.9% annually. The billing is so confusing because we are dealing with 3 different companies (Sunrun, Silicon Valley energy company that buys the electricity from Sunrun (just found out at 7cents per kWhs when Sunrun charges us 37 cents!!) and PG&E for delivering the energy). None of this was explained to us- all you hear is that you get credit on your PG&E bill- which is another lie. Be aware that your monthly PGE bill is low because it is NOT for your electricity use (that's just for $10 monthly meter reading and gas only), at the end of the year you get a surprise large bill from PG&E called "Tru Up" for your yearly usage. Once we found out all these, it was too late. it's impossible to get out of a 20 year contract because of the egregious penalties. DO NOT LET THEM FOOL YOU!!!!

To anyone considering solar, PLEASE go with any other company than Vivint. There are so many to choose from. It's true what all the other negative reviews say. They will give you what you want until you sign that contract and the panels are up/working. Their customer service is beyond horrible. We've had years of issues, but this year was the worst. We knew there was something wrong with our panels and had to fight for weeks to get someone out to check them. Once the tech came out he confirmed we had several pieces not working correctly. He said he'd get the parts and return. He NEVER returned. We had to fight again for MONTHS to get someone out. Every customer service rep said they had NO record of anyone coming to our house and that our system was perfect. I mean, what a joke! After 3 months we finally got in contact with a supervisor named Miles and he all of the sudden found the record of a tech coming out and that we did have an issue. Meanwhile, our true-up is through the roof. He said he'd open a case to see if we could be reimbursed for funds lost since their company never returned to fix our parts. But of course, case was closed and they didn't find any money they owed us. I mean, not shocking since they are the WORST solar company. To this day we are still waiting for the tech to come "fix" our system. I will NEVER refer them to anyone and I will tell anyone who asks about solar to NEVER go with Vivint and all of the horrible and shady things they do. What a pitiful company!

Note: Prices for installed systems are shown after 26% federal solar tax credit. Prices for individual panels, inverters, batteries, and DIY complete system kits are shown before federal tax credit.
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.
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
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.
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 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.
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.
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.
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.
