Case studies for installed renewable energy systems; solar PV, solar thermal and wind energy in Southeastern Massachusetts
Wequassett Resort and Golf Club, Harwich, MA
Solar PV Ground Mounted Solar System
Wequassett Inn, LLP (Wequassett) elected to pursue renewable energy in August 2014 with the Cape Cod solar company, Clean Energy Design, LLC. Clean Energy Design completed the installation of a turnkey 23.52 kW, stand-alone, multiple array solar photovoltaic system consisting of 84 high-efficiency SolarWorld 280-watt mono-crystalline panels. This system has surpassed the expected production of energy for 2016. The original target for the summer months of June, July, and August 2016 were 2.65 MW, 2.65 MW, and 2.38 MW, respectively. The actual energy produced for the months of June, July and August were 3.35 MW, 3.23 MW, and 3.5 MW, respectively. Due to it being the hottest summer in recorded history, this summer was ideal for harnessing the power of the sun!
From May 2015 to December 2015, this solar photovoltaic system produced 20.68 MW, and from January 2016 to August 2016, the system produced a total of 20.52 MW. According to this, it is predicted to produce approximately 10-15 additional MW towards the year’s end.
St. Peter’s Lutheran Church, Harwich, MA
Solar PV System
This 34.04 kW photovoltaic system installation consists of two arrays totaling 148 high-efficiency SunPower modules and 4-SMA 8000 inverters. Since the completion of the installation in October of 2011, this solar installation has been producing an average of 4300-4800 kWh monthly enabling the Church to produce well over 110% of the electricity it consumes and net zero their bill. They are able to donate the extra solar power produced to other non-profit entities to satisfy their mission of helping others.
According to the MASS CEC, this particular Clean Energy Design project is one of the most efficient PV systems in the area, producing in the top 1% of comparable systems!

Residential 4.9 kW PV System in Barnstable, MA
This is an email we received from a happy customer April 26, 2014.
Thought you might like to know that in the 12 months since our panels “went live” last April we have kept track of our NStar statements each month. We built up a credit over the summer and into the fall, reaching a maximum of $204.32 in October. Then through the winter, with less production, that credit balance gradually dwindled till last month we stood at only $6.61. We wondered if we would, at last, have a bill to pay … but this month’s statement showed that we are again moving back in the right direction, now with a credit balance of $37.93. Looks like the amount we’re producing annually just exceeds our use by a small margin.
Thanks for our great panels … and for figuring our use vs. production so well!”

Solar PV, Wind Energy, and Solar Thermal Integration – Off Grid
All systems designed and installed by Clean Energy Design as described in this interview with Tom Wineman, owner of CED. Interesting challenges since the lighthouse was built in 1876. The result was a beautifully integrated and powerful, completely off-grid system!

Secure Storage, Brewster, MA
Solar PV Roof-mount Installation
Clean Energy Design installed 69 Sunpower Modules (SPR 215s) on the roof of Secure Storage of Brewster, MA along with 4 inverters (SPR 6000m) in the summer of 2009. Just 2 short years later, the results are impressive with over 52,600 kWh generated to date, offsetting the CO2 emission of 66,000 lbs!

Solar Building Integrated (BIPV) Roof Shingles
The Clean Energy Design team has covered five-hundred square feet of the roof of the Cooperative Extension Building at the University of Rhode Island. They used cutting-edge Sunslate photovoltaic roofing tiles manufactured right in Poughkeepsie, NY by Atlantis Energy Systems. The tiles lay flat on the roof in place of typical roofing shingles serving as both a roof surface and as solar power collectors. The plan was that he 4.4-kilowatt system would generate approximately 5,580 kilowatt-hours of electricity per year, enough to supply approximately 17 percent of the building’s electricity use. The final result is that it is a very efficient system is actually producing 25 percent of the building’s electrical needs. This system not only offsets utility costs but it provides an excellent tool for demonstrating the use of PV systems as a viable energy resource, raising awareness in the community of the need and opportunities for implementing clean energy in Rhode Island.
The solar tiles are wired together on one circuit and linked to a control panel inside the Cooperative Extension Education Center, a 3,300-square-foot, one-story structure built in the 1930s and expanded in 1991. The panel allows the building occupants to monitor the amount of electricity being generated. An educational display about the system will soon be mounted next to the control panel.
