Our Recommended

Installing a home solar battery is the key to unlocking true energy independence and peace of mind. Without a battery, grid-tied solar panels shut off during an outage, leaving you in the dark. But with a battery, your home can keep running on stored energy when the grid goes down.

Eden Prairie, MN

“Centauri was a pleasure to work with and would recommend them to anyone. It was only ~6 weeks from the date of signing the first documents until they were installed which is probably faster than anyone else could have done. The system looks great, is performing well, and overall everyone at Centauri couldn’t have been better.”

Solar Reviews

Vanessa Dee said:

Rosemount, MN

“We had 52 PV panels installed. We interviewed 5 Solar companies and chose Centauri Systems. We received a fair bid. Dylan and Noah were great to work with and responded to texts and emails immediately. The install crew was professional, efficient and knowledgeable. We are working with them to install more panels to expand our system.”

Eagan, MN

“The sales process was very helpful – but not too salesy or pushy. Very direct and honest. The team that installed the panel system was super friendly and kind… The entire crew has done a fantastic job keeping up up to date on next steps. I highly recommend them.”

“I got quotes and met with 8 separate solar companies. Centauri had the best price and the best panels. I kept waiting for something to go wrong but it never did. Great partnership and couldn’t be happier!”

Garfield, MN

“I really enjoyed this group from the beginning, helpful and friendly. They got the job done fast and efficiently! It took them just 3 days to install and within a couple of weeks it was online. After the first billing month, the system has produced at or just above their predicted amount. I would definitely go back to them again!”

Champlin, MN

“Centauri Systems installed my solar panels about a year ago and everything has been great. I have been getting negative bills (Xcel credited my account) for the spring and summer months. I went with Centauri Systems due to their honesty of cost and process. Their price was a lot better than the big solar installers. ”

Tyler Bobert said:

Afton, MN

“I couldn’t be happier that I picked Centauri Systems for my solar install. Overall just an incredible experience. I’ve never worked with a company that puts this much pride in what they do. They use the best panels/inverters, put a lot of thought into their installs and are incredibly responsive to their customers. If you are in the market for solar please give Centauri a call. You are doing yourself a disservice if you don’t.”

Patricia Bergh said:

Minneapolis, MN

“From the first meeting with Centauri to the final inspection, we have had nothing but positive experiences. We got three estimates (including from one of the largest solar installers) and we chose Centauri. Every single time I called or emailed (which was a lot) I got a response back immediately.”

“Centauri Systems was an astounding team to work with. When it came down to comparing the quotes, it was a no brainer. The installers were very professional and kept me up to date on where things were at with the project, what the next steps were. James and Centauri Systems as a whole has been a pleasure to work with and I will 100% be recommending them to coworkers, neighbors, family, and friends.”

Little Canada, MN

“Centauri was very good to work with overall, we were happy to work with a local company. Solar is a bit hard to understand and Centauri staff answered all of our questions so that we felt comfortable to move forward with large system on our home. Centauri offered the best price for the equipment and install, which helped make the system possible. System is now operating and generating power and we are thrilled”

Deb & John S. said:

Oak Park Heights, MN

“Our decision was based on competitive pricing, warranty and the quality of solar panels they used. The installation crew was extremely professional and personable. They worked together like a finely oiled machine and did a super clean up job when finished. We are happy with the results and highly recommend Centauri Systems!”

Trevor Thompson said:

Burnsville, MN

“Working with Centauri was amazing from the very beginning. Especially with Dylan, he was great to work with. The Quote and Product was superior from any other quote/product combo I got from more than 5 other of the national companies. Finally service – best customer service I’ve had from a company or contractor in some time. I couldn’t recommend Centauri more.”

Mark Skinner said:

Shakopee, MN

“Centauri Systems installed our 50 panel (20kWh) system last December 2022 and we could not be happier. We had received 5 other quotes and the price and sales process was the best with Centauri. Dylan, the sales rep, was outstanding, very knowledgeable, and extremely responsive to all our questions. Even 8 months after the install, I can text/email Dylan and he will respond within minutes.“
