About Cotuit Solar’s Philosophy, Founder, Team and Experience.

Our Philosophy

We are passionate about bringing solar energy to as many people as possible in order to conserve local resources and reduce our carbon footprint.  We are proud of our work installing solar on Cape Cod, Martha’s Vineyard and Nantucket households and businesses.  The Cotuit Solar Team is a group of conscientious individuals who try to live in concert with the philosophy – believing that small actions by many are the means to a sustainable future.

Our Founder

Conrad is the principal of Cotuit Solar and is NABCEP (North American Board of Certified Energy Practitioners) certified in both PV and Solar Thermal. Conrad has directed over five hundred system installations to date ranging from small off grid to 1.14 MW.

Conrad has been an instructor for Cape Cod Community College, Cape & Islands Self Reliance solar workshops and Waquoit Bay National Estuarine Research Reserve. He served on the Board of Directors of SEBANE (Solar Energy Business Association of New England) and the Board of Advisers for the Upper Cape Cod Regional Technical High School. Conrad monitors a number of technical journals around the Renewable Energy and sustainability fields.

Additional sustainability projects include:

  • Designing and producing the Cotuit Dry Toilet
  • Nutrient recycling gardening
  • Local sustainability indicator projects
  • Quahog sub-tidal aquaculture
  • Various window thermal insulation methods
  • Quick response Radiant floor systems

When he’s not working (kind of rare) you can find him gardening, sailing, kite boarding, flying airplanes, boat building, chopping wood, daydreaming up some strange design or keeping one of his ancient vehicles on the road.

Steve Colman- Year in Review

"I just passed the one-year anniversary of the installation of my photovoltaic system, which consists of 25 LG300 panels, 7500 W, installed by Cotuit Solar. The post-installation analysis estimated that my yearly production would be 7875 kWh. My actual production for the year just past was 8310 kWh. I’m very happy about that we exceeded expectations, and I’m glad that the estimate was honest and conservative. My net meter was at 550 kWh, so my total use for the year was 8860 kWh. Of this, I estimate that 5360 kWh was for my house and 3500 was for my electric vehicle. So solar covered all of my household needs, and almost 94% of my total usage. I’m very pleased with the system and with the work that Cotuit Solar did. The people are great and my system has performed flawlessly."

Ed & Peg Crawford

“Our home is all electric heat! We had been planning a solar array for a while and trying to decide between whether to own or to lease. We decided that owning was in our best interest and found a local company, Cotuit Solar. From the initial inquiry through the design and installation to the final PTO they were with us every step of the way. We did ask a lot of questions and they taught us about solar energy as it pertains to our setup. Communication was great and the whole crew did an excellent job. We like that they are local, committed to renewable energy, and are experienced. Thanks, Ed & Peg Crawford.”

Cotuit Solar was extremely helpful before, during and after my solar installation. They completely demystified the sea of paperwork, necessary for the various state and federal tax credits and other incentive programs.

"I am totally impressed with Cotuit Solar. We had a great experience with a very well organized and impressively staffed  company. I feel that we got spoiled by the outstanding service that Cotuit Solar offered. We had a large and a challenging installation and reached out to get recommendations from 3 well-esteemed solar companies, one being Cotuit Solar.  Cotuit Solar came back with the best design and a very competitive price so we chose them . But that was just the beginning of good results. The installation went perfectly and right within the time slot we needed. Furthermore Cotuit gave us so much assistance with the financial side, the grants and loans. We realized why many of our peers recommended them. This organization is so well organized, personable and responsive. There is always a knowledgeable person at the office to answer questions. I feel so fortunate about the entire project."

Cotuit Solar installed my 5.4 kWh PV system in January of 2012. Since then it has performed flawlessly. Absolutely no maintenance cost during that time. It has been a net-zero system. Love those quarterly SRECs.

“I was happy with Cotuit Solar and I'm glad I chose them over the national company that I considered. I had a complex installation, and there were a few glitches, but the staff responded to these quickly and well. The basic installation of my 7.5 kW system took only one day (after some weather delays), and the staff got us through the inspection and permitting process efficiently.”
