    • SMART 3.0 monthly production payments
    • Sales tax exemption (6.25%)

  • Most homeowners in Massachusetts still see 7–10 year payback periods, with long-term savings well beyond.

What to Know Before You Start

The end of the federal homeowner-owned solar tax credit in 2025 changed the economics of solar. For Massachusetts residents, however, the picture remains strong:

  • The cost of solar has fallen – from 2010 to 2024, solar costs have dropped 65% (DOE/NREL data).
  • Payback is still attractive — most households break even in 7–10 years, only 2–3 years longer than before.
  • State programs bridge the gap — SMART payments, state tax credits, and exemptions continue to deliver reliable value.
  • Class 1 REC payments add extra income — homeowners earn credits for energy produced, which utilities buy to meet state renewable goals.
  • Third-party ownership models add options — leases and PPAs still benefit from the 30% federal credit through2026 with certain restrictions, lowering upfront costs.
  • Rising electricity prices increase savings — making solar a hedge against long-term utility costs.

In short, while federal support has narrowed, Massachusetts incentives and market conditions keep solar a smart long-term investment for many homeowners.


Step-by-Step: How To Navigate Incentives in 2026

  1. Decide on ownership model
    • Lease or PPA: Still eligible for federal incentives with certain restrictions.
      . Lower or no upfront costs. You benefit through reduced energy bills, not tax savings.
    • Buy outright or finance: No federal credit available in 2026. Consider state savings and long-term value.
  2. Explore Massachusetts incentives
    • Enroll in Class 1 RECs or the SMART 3.0 program for cash payments on the energy you produce.
    • File for the MA 15% state income tax credit using Form Schedule EC.
    • Take advantage of sales and property tax exemptions automatically applied to qualifying solar installs.

  3. Get multiple quotes
    • Compare offers from local and national providers. Look for transparent lease/PPA terms or strong state-level guidance if buying outright.
    • Make sure providers walk you through post-2025 savings scenarios and clarify ownership models.
  4. Track your long-term ROI
    • Even without the federal credit, solar can still provide strong lifetime value through energy savings, state support, and against rising electricity rates.
    • Consider combining solar with battery storage, which may offer additional state or utility incentives.

Helpful Tips & Watchouts

  • Don’t be misled by outdated offers: Some ads or sales pitches may still reference 30% federal savings—those no longer apply to homeowner-owned systems.
  • Ask for a 2026 ROI breakdown: Any reputable installer should provide updated savings models that reflect the current incentive landscape.
  • Consider hybrid financing: Combining state support with solar loans or leases can still result in monthly savings over utility bills.
  • Keep paperwork organized: You’ll still need tax documentation for the MA income credit and utility enrollment.
  • Think long-term: 2026 solar buyers can still break even in 7–10 years, especially with rising electricity rates.
