Solar Installation Services for Homes & Businesses in MA

• Step 1 — Free Consultation and Site Assessment
  We start with a no-cost conversation about your energy usage, roof condition, and goals. Then we send a team to assess your roof’s angle, shading, structural condition, and your existing electrical infrastructure. This step determines the right system size for your home or building.
• Step 2 — Custom System Design
  Our engineers design a system sized to your actual energy needs — not a one-size-fits-all package. We also handle all permitting paperwork required by your local Massachusetts municipality, which varies town to town.
• Step 3 — Installation
  Our licensed electricians and installation crew mount the racking system, install panels, connect inverters, and set up monitoring. A typical residential installation is completed in one to two days.
• Step 4 — Inspection and Utility Connection
  After installation, we schedule the required municipal inspection and coordinate with your utility (National Grid, Eversource, or other) to activate net metering, so excess power you generate earns bill credits rather than going to waste.
• Step 5 — Ongoing Support
  We’re available after installation for questions, maintenance guidance, and system monitoring support. Solar panels generally require minimal upkeep — our team can advise on cleaning schedules and annual checkups.

The cost of a residential solar system in Massachusetts is typically based on system size, panel brand, and roof complexity. Key factors that affect your final price include:

• System size (kW)
• Roof type and pitch
• Electrical panel upgrade requirements
• Battery storage add-on

The good news: multiple incentive programs bring the net cost down significantly. See the incentives section below.

1. SMART Program (Solar Massachusetts Renewable Target)
   Massachusetts’s SMART 3.0 program pays solar owners a fixed rate per kilowatt-hour their system produces — on top of any net metering bill credits. The base rate for most residential systems (under 25kW) is currently $0.03/kWh, locked in for 10 years. Adding battery storage or other qualifying features can increase your total rate — in some cases to $0.10/kWh or more. Rates follow a declining-block structure — the earlier you apply, the higher the rate you lock in. The program is administered by Massachusetts’s three investor-owned utilities: Eversource, National Grid, and Unitil. Customers in Municipal Light Plant (MLP) territories are not eligible.
2. Net Metering
   Any excess solar energy your panels produce and send to the grid earns you bill credits from your utility. Massachusetts has one of the stronger net metering policies in the country, crediting you at or near the full retail rate. Learn more on our Net Metering Services page.

3. Massachusetts State Tax Credit
   Massachusetts offers a 15% state income tax credit on your total solar installation cost, capped at $1,000. Most systems hit the cap — any system costing $6,667 or more will max it out. Key details:

• Non-refundable, but unused credit carries forward up to 3 years
• Must own the system (cash or loan) — leases and PPAs don’t qualify
• Must be installed at your primary Massachusetts residence
• Stacks with SMART payments and net metering — claiming it doesn’t reduce the value of other programs
• Claimed on Massachusetts Schedule EC when you file your state return

4. Federal Incentives
The 30% federal residential solar tax credit (Section 25D) ended December 31, 2025 and is no longer available to Massachusetts homeowners purchasing with cash or a loan in 2026.
If you’re considering a lease or PPA, the solar company that owns the system may still claim the commercial federal credit (Section 48E) and pass some of those savings to you through lower rates — worth asking about when comparing financing options.
SMART payments, net metering, the MA state tax credit, and both tax exemptions were not affected by this change

5. Sales Tax Exemption
All solar equipment is fully exempt from Massachusetts’s 6.25% sales tax. On an average system, that’s roughly $2,000–$2,500 in savings at purchase.

6. Property Tax Exemption
Solar adds value to your home but won’t raise your property tax bill. Under M.G.L. c. 59, §5, the added home value from a solar installation is exempt from local property tax assessment for 20 years.

• Electricity rates rank among the highest in the country — making solar savings bigger and payback faster
• Consistent top-ten state for solar adoption per capita
• Strong incentive stack: SMART 3.0 payments + net metering + state tax credit + two permanent tax exemptions
• Three established utility interconnection pathways: Eversource, National Grid, and Unitil
• Supportive local permitting across most municipalities
• Average payback period of 6–9 years — after that, 25–30 years of essentially free energy
