The Town of Falmouth is excited to implement a solar array on the 4.2 acre capped landfill on Woods Road. The 875 kW AC array has an expected annual output of 1,500,000 kWh and will produce enough renewable energy to offset ~70-75% of municipal electric use. Over its 20-year lifespan, the array is estimated to save the Town of Falmouth $1.995 million in energy costs.

  • October 2019 - Falmouth issued RFP for solar array project and received 8 proposals that met the requirements
  • February 2020 - Staff presented the solar array proposals to Town Council and recommended moving forward with Tangent Energy Services; Town Council approved the recommendation
  • May 2020 - Town Council approved signing the Power Purchase Agreement with Tangent Energy Services
  • The pandemic, and accompanying supply chain issues, delayed the installation of the array. Construction began in early 2022, including the creation of an access road to the top of the landfill, the installation of concrete bases on which the racking system rest, and finally, the placement of the solar panels and electrical connectivity. Construction concluded in January 2023.
