Tesla provided the best value added ($/kW), including very competitive financing. I was very pleased And impressed with the installation done by Brock and the Tortuga Team. Very experienced, high quality and seamless installation. They clearly explained and consulted with me every step of the installation process.

As the title states, we picked the panel for the efficiency and warranty. I doubt we will be displeased.

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

The Power Trip folks were very clear about every step of the process of installation. My panels went on the roof in a day, and the system was started after the city inspection. I love looking at the web interface showing me what I am producing--it is my happy place! I would do it again if I ever moved.

Forget trying to get customer service from Sunrun. I began trying to contact them over two weeks ago... no reply yet. If you phone, you can have a wait time of up to 2 hours (maybe more) but they say they'll save your place in line and call you back... So you're meant to wait around for two hours because once they've made the call the apparently make no further attempt to call you back. This is the worst customer service imaginable. Steer clear of Sunrun. There are surely more reputable companies. If I didn't have to give them a star to get this published, I would not.

Mean lady that calls every month
,4 days ago
Where to start. First my panels didn't work for 2 months and no one contacted me! No refund either! Then my electric was high again and 5 panels didn't work, again no one contacted me! THEN my bill was high again and my panels weren't communicating, AGAIN no one contacted me! But they sure do take your fee every month and don't reimburse you when they're broken. Also i have to pay THEM out to cancel, so i'm stuck with a sucky solar panel team!

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.
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) electricity is converted into alternating current (AC) electricity that can be 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 power of the sun. There’s no utility to fall back on. This means the solar installation needs to power the home not just during the day, when the sun is shining, but after dark as well.
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
