Massachusetts Island Famous for Relaxation Discovers Solar Peace of Mind

Cuttyhunk Island—a mile and a half stretch of land at the outermost band of Massachusetts’ Elizabethan Islands—is home to a single school, many bed & breakfasts, and little more than 50 permanent residents. The population can swell into the hundreds in the summer as tourists and travelers flock to this quaint little New England island for fishing and relaxation.

Everything that comes to the island, from food to fuel, must be transported via boat or barge. For barges, that’s a three hour drive from the mainland.

Being so far away from mainland Massachusetts, it made sense for Cuttyhunk Island to have an inexhaustible source of energy in the form of solar PV.

Big Green Takes a Barge Ride

Transporting a 351.9 kW ground mount solar system to an island is no easy feat. But with careful planning and local expertise from Synergy Solar’s foreman, Cuttyhunk’s solar PV system was installed in no time.

Our big green post-driving machine (GRT), two barges of racking material, gravel, a drill rig, and other construction equipment had to be transported to the island to begin construction. Two trips were made on the first day to get all materials and equipment to the island. Another trip was made halfway through installation to take the drill rig and GRT off the island, and another trip was made at the completion of the project to transport the remaining equipment off the island.

Loading solar racking materials

Another transportation challenge was that the GRT moves very slowly and there was no trailer on the island capable of moving the post-driver. Our crews were required to drive the GRT to the barge about a mile away from the dock with a truckload of racking which was then unloaded at the site. There was little room for error in this process as each barge trip was time-consuming and costly. We worked closely with the barge captain to ensure the safety of equipment, materials, and crew members with every trip.

Other Site Challenges

Because the project site was hilly and rocky, we knew there would be areas where we would not be able to drive posts into the ground. To prepare for these challenges, a drill rig was transported to the island to drill out any holes. Once the hole was driven, it was filled with gravel and then compacted to create better post-driving conditions. With the approval of our in-house engineering team, extra-long post top brackets were shipped to the site to make the rows level.

Despite major site access and topographic challenges, our crews were able to install the ground mount system quickly. Now, Cuttyhunk Island residents and visitors enjoy the peace of mind of an unlimited energy source.
