Optimum Solar Group Maintenance

According to the customer reviews, the majority of customers describe Optimum Solar Group to provide excellent customer service throughout the installation process. Of the sources we scoured, there is no mention of maintenance issues post installation. The brands of solar panels provided by the company come standard with a 25-year warranty.

There were 2 customer reviews that received 1* rating from our research. Both customers expressed discontent with the installation companies that were allocated to their projects. One of these customers also mentioned that the owner and sales agents were inflexible and delivered extremely poor customer service. Nevertheless, the remaining 43 of 45 reviewers (96%) provided ratings of 4* and better, many of which mentioned excellent service levels and responsiveness from the owner and his partner throughout the installation process.




Overall, Optimum Solar Group seems to offer good quality services and is well-reviewed for a fairly new company. The majority of customer feedback shows that the company provides a personalized approach to its work which also indicates that the company relies mainly on the owner and co-owner to operate since they do not have their own sales or installation teams. This raises concern about the company’s capacity to handle multiple projects in different locations simultaneously.

The company also does not make use of its own installers; therefore, our experts recommend that customers take note of the third-party aspect of this company’s installation services.

System was installed and works great. Was explained well and took care of any extra issues that popped up. Not all communication was fast, but questions were answered. Would recommend for solar projects, and will be using then again as well. Installer was professional and will be in business well after warranty on panels are up?

Marshall helped me out in contacting the company that installed my solar panel system after experiencing a problem with the system. Note that this system was NOT installed by Optimum Solar Group! Marshall went out of his way to provide me contacts and help me out as best he could. People like him reflect well on this company. Thanks Marshall!

It was a pleasure dealing with Optimum Solar. The process was flawless from start to finish.
Marshall seamed to handled everything with ease.
If I had any questions he answered them quickly without delay.
I had a bit of a bidding war with another company and Marshall was able beating their price without a problem. The system that they developed for me was spot on.
I highly recommend Optimum Solar without hesitation.

After I decided that I wanted to have a solar electrical system installed I reached out online to a few to different vendors for quotes. Marshal at Optimum Solar called me back immediately to get the quote rolling by answering any questions that I had. He was great to work with. He always returned any communication whether email, text message , or call promptly and courteously. Once the deal was made and all the supplies for the solar system had been ordered the local installer had everything set up on the house and garage and they answered any questions I had on the spot. I haven’t had the system long enough to go into more detail about it but I can say the service through Optimum Solar was top notch.

I've always wanted to get solar panels to help with my utility bills. Marshall at Optimum basically took care of everything. He worked with Minnesota Power to do an assessment and then submitted the rebate request from them just after midnight on or about April 1st I think. We were one of the 75 projects to get that rebate. Once all that was done Belknap Electric came and set up the 14 panels and all of the other electrical work. It took only about a day and a half. We have been generating on average 24-25 kwh per day for the last month plus. Very happy so far!

This year I decided to take the leap and get solar after the recent utility rate increases. I got a few estimates and ultimately decided to go with optimum solar. Marshall was great to deal with, not pushy, patient, knowledgeable, gave me some different options for what would suit my needs best and shortly after I had the building ready for the solar, they had the job completed. I'm happy I chose these guys.

Marshall was very helpful in designing our system and helping us navigate our questions and concerns. He was very knowledgeable and helped us make an informed decision. Our new system has virtually eliminated our previously RIDICULOUS energy bills, it's already been a great investment for us. Optimum gave us the quality we were looking for, as well as a great experience!
