Commonwealth Solar Review

Commonwealth Solar experts are highly recommended and the best solar company with which we have worked. We obtained 4 estimates for a solar project on our property. We have a unique property with perceived limitations that 3 of the 4 companies all but dismissed for a solar array and battery. Commonwealth Solar was the only company to listen and make a site visit to confirm a system could be designed and installed. Moreover, we had specific goals for our system design that other companies stated we could not build. Commonwealth Solar discussed our goals and considered our needs during system design. And it was installed on a reasonable timeline. All aspects of the process were discussed, followed upon, and adjusted as needed. I could not be more satisfied with the design, installation and customer service we have received. Above all, their design and installation cost estimate beat all other competitors. I highly recommend this company.

Solar installation for 420 Highbridge Rd

We installed a solar array on our house with inverters and battery backup. We liked the fact that it offset our bill from the utilities to our base charge. But the best part is we have power when the utilities is down! In March there was a period of 2 weeks that our community was without power and we went by with no interruption. We are fortunate and grateful for the addition to our home.

We survived the windstorm here in KY thanks to Commonwealth Solar

We had Commonwealth Solar install panels on our farm last year and this spring we had two 100mph+ windstorms that knocked out power all over the state. We were luck in that it was sunny every day after that, and between the solar panels and our battery backup, the system kept our entire house and farm online through the outage like nothing had happened. I was a bit skeptical about how good the system would be; however, I am a believer now. Between the prevention of days without power, and our power bill being the base connection fee, I am a believer now.

Absolutely outstanding company

We have lived fully off grid for about 15 years and have had experience with a number of solar contractors during that time. The primary problems I have run into in the past have been contractors who claim expertise they turn out not to actually have, low quality of work, work not getting done in a timely manner, and opaque billing that allowed me no ability to budget. Commonwealth Solar has none of those problems: they exceeded all of my expectations and have been hands-down the best of the best I have had the pleasure to work with. They are extremely knowledgeable, skilled, efficient, and honest. The entire project took less than 6 weeks from initial quote request to done, and 3 weeks of that was my own delay due to travel plans. Once I was back and able to let them start they had installation done in 3 days, including the time it took to remove the old panels. The Commonwealth Solar team wrote a detailed proposal and stuck to it, and when I considered a few additions midway through, they let me know up front what those would cost, so there were zero surprises when the final invoice came. All costs were fully transparent and reasonable. Anytime I had questions, they answered quickly and in as much detail as I needed. The quality of their work is top-notch and I was impressed by their solid expertise, how efficiently they got the job done, and how perfectionist they were with every detail. I recommend them 100%. I'm so impressed with them that I have recommended them to multiple people and I am planning to hire them again for additional work I need done this coming fall.

Responsive and knowledgeable!

The Commonwealth Solar team with Daniel Wier as the leader have been helpful to repair my solar array after a wind storm. They were responsive and very knowledgeable.
