Fabulous Service!

In April of 2013, Clean Energy Design placed 15 solar panels on our roof in Barnstable. Tom and his team did a fabulous job, right from the start … including accompanying us before the Old King’s Highway Commission! That initial up-front investment was reduced over time by the absence of our former $1000/year electricity bills, by rebates and tax credits, and by Solar Renewable Energy Credits (SRECs) — quarterly income from selling excess electricity. By the fall of 2018, we had broken even, and thereafter we became increasingly “money ahead!” Then in February of 2021, we replaced our Forester with an all-electric Chevy Bolt … and lo and behold, we eventually started to get small ($90-$120) electric bills. Time to add ten more panels! So this year, Clean Energy Design once again delivered the goods professionally, promptly, and courteously. We could not have been more pleased with Tom and his entire team, from the office staff who handled all the permitting challenges to the hard-working gang who installed and wired in our newest set of panels. We would recommend Clean Energy Design to anyone!

Best Products, Honest, and High integrity.

We installed a custom engineered 10.56 kW solar photovoltaic system and could not be happier with the results. The Clean Energy Design Team was professional, courteous, and continually kept us informed through the entire process. We are now seeing a negative balance on our electric bill and reaping the income from the sale of our SRECs! We are especially excited about our contribution to the environment by utilizing clean renewable energy from the sun." For more than a year now after installing, we paid ZERO on our monthly average of about $ 500+, and we have our Eversource statements to prove it. We also receive an average SRECS energy sale of about $ 1500 every 3 months for the past 9 months, and, you guess it, we have the pay stubs from Clean Energy Design to prove it! It is the right choice with Tom Wineman!
