The Tesla installation crew was extremely professional, knowledgeable, and detail-oriented. They displayed a huge amount of expertise and were very precise in their installation of not only the panels, but the POWERWALL as well. We are thoroughly pleased and highly recommend Tesla.

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

It’s advertised when there are power outages the back up Brightbox battery kicks in; thought it was part of the system. Turns out, its separate and has to be stated in the contract. Sunrun refuses to upgrade and now I am stuck for 20 years. Beware of salesmen

Worst decision I have ever made my whole entire life. Please stay away from Vivint Solar. They have the worst customer service and even worst "Executive Resolution Experts". My panels never work like they're supposed to and as of now have been waiting over 60 days for someone to figure out what's wrong this time. according to their contract, we are to have resolutions to issues in a timely manner or else the company is in Seller's Default and should be allowed to break the contract. However, when the company is able to decide what a timely resolution is, you will never win or get them to give you the work required. AND DON'T LET THEM BLAME COVID. This has been an issue since April of 2019. Long before COVID19. Save yourself the trouble and stick with NV Energy. At least when you call NV Energy you get someone from this country that knows the details of your account without having to put you on hold for over 15 minutes to "Check their resources". Stay on the Grid people!

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?
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
