Projects We're Proud Of
A look at solar installations we've completed for homeowners, businesses, and farms across MA, NH and New England.
From residential rooftops to large commercial arrays, every project starts with an honest conversation and ends with a system built to perform.
Featured Project
Phoenix Precast — Concord, NH
Precision from the sky. Power on the ground.
Phoenix Precast now runs on 473 high-efficiency panels across two buildings in Concord, NH — generating 328 kW of clean energy and completely eliminating their electricity costs.
The second system — a 224 kW installation completed in February 2025 — brought both facilities to 100% energy bill offset. Together, the two systems generate approximately 400,000 kWh of clean energy per year, future-proofing Phoenix Precast's operations for decades to come.
Completed February 2025 · Commercial · Concord, NH

Upswing Farm
Pepperell, MA
Kevin and Brittany Overshiner transformed a historic hay and dairy farm into a certified organic, four-season vegetable farm — then partnered with Critical Mass Solar to power it sustainably. The result: lower energy costs, greater self-reliance, and a stronger mission to deliver high-quality, locally grown produce to their community.
"The collaboration with Critical Mass Solar was seamless. Their responsiveness and expertise in tailoring a solar solution to our farm's unique needs made all the difference."
