TECHNICAL CAPABILITIES

COMMERCIAL & RESIDENTIAL SCOPES

Heavy-duty equipment installations, diagnostics, and code modernizations across Lexington.

SCOPE // 01

Residential Solar Array Design & Installation

Custom-engineered roof and ground-mount photovoltaic systems, permitted and interconnected with your utility. We model your actual consumption data so offsets are realistic — most of our customers see near-zero electric bills, cars included in the math excluded.

SCOPE // 02

Heat Pump & Ductless Mini-Split Conversion

Cold-climate air-source heat pumps and multi-zone mini-splits that replace oil and gas forced hot water or steam systems. We size head units room by room, preserve existing radiator aesthetics where you want to keep them, and qualify the full project for Mass Save rebates.

SCOPE // 03

Home Battery Storage & Backup

Enphase and Tesla-class battery systems that keep critical circuits alive through outages and shift your usage off peak rates. Paired with solar, storage lets you ride through nor'easters and monetize your excess export instead of giving it away.

SCOPE // 04

Boiler Tune-Ups & Heating System Service

Annual combustion analysis, skim and flush service for steam boilers, and hydronic system care for older Lexington-area homes. If your boiler is near end of life, we'll show you the electrification numbers honestly — and if it isn't, we'll keep it running safely for years.

Customer Testimonials

Verified Feedback from Neighbors in Lexington

Real feedback from local property owners who trusted Great Sky Solar for reliable, high-quality service.

★★★★★

Sara Cook Verified Local Customer
★★★★★

“Highly recommend Great Solar. They are just fantastic. The immediate feedback on energy consumption/export reinforces that this such a good thing for the planet. Just do it with Great Solar.”

Umesh Kurpad Verified Local Customer
★★★★★

“We were very impressed with Great Sky's competitive quote and professional team for our roof-based residential solar project. After signing our Letter of Intent, we moved quickly through the engineering and permitting stages of the process. Unfortunately, we were not able to settle some legal details with our condominium neighbors in time for the final contract to be signed, so we had to put our plans on hold. In future, we look forward to working with Great Sky again if our situation changes.”
