Introduction

If you looked into solar last year and haven’t followed up since, there’s actually good news worth knowing. New financing options have emerged that allow Massachusetts homeowners to capture close to the same financial benefit that the old federal tax credit provided: sometimes more, depending on your situation. Massachusetts state incentives are still fully in place. And the overall cost of solar has dropped significantly heading into 2026.

What did change is the form. The 30% federal credit for homeowner-purchased systems expired December 31, 2025. But the credit didn’t disappear; it shifted. It now flows through third-party financing arrangements, where the financing company claims it and passes the savings through to you. That’s a different structure than most homeowners are used to, and most of what you’re hearing from solar companies right now is designed to create urgency rather than explain it.

This article is the explanation. What changed, what didn’t, and how to think about whether any of this makes sense for your home right now.

What Happened to the 30% Federal Tax Credit

The 30% Residential Clean Energy Credit — Section 25D of the tax code — expired on December 31, 2025, under the One Big Beautiful Bill, signed into law on July 4, 2025. For homeowners who purchased a system outright with cash or a loan, that credit is no longer available for systems installed after that date.

This was a significant change. The credit had been in place for years and was a major factor in the financial case for solar. Its removal is real, and any company telling you otherwise isn’t being straight with you.

But the full story doesn’t end there.

What Replaced It

The same legislation that ended 25D left a parallel credit intact: Section 48E, the commercial Investment Tax Credit. At 30%, the value is identical. The difference is who claims it.

Under 48E, the credit goes to the entity that owns the solar system — not necessarily the homeowner. In practice, this means third-party financing products: leases, power purchase agreements (PPAs), and newer prepaid financing structures where a financing company owns the system, claims the federal credit, and passes the financial benefit through to you in the form of lower payments or better terms.

Historically, leases and PPAs had a poor reputation — and often for good reason. Predatory structures, long lock-in periods, and terms that favored the lender were common.

But a new generation of financing products is emerging that are meaningfully different: fully transferable if you sell your home, with no prepayment penalties, and an ownership transfer to you after a set period. The consumer captures the full energy savings and avoided utility costs. The financing company takes only a portion of the tax credit and system depreciation.

The 30% credit didn’t disappear. It moved. For the right homeowner in the right situation, the financial case for solar in 2026 can be nearly as strong as it was in 2024 — through a different vehicle.

What Massachusetts Homeowners Still Have

Regardless of federal policy, Massachusetts has its own programs that remain fully in effect.

The SMART Program pays you for every kilowatt-hour your solar system generates — not just the surplus you sell back to the grid, but all of it. The rate is fixed for a set period, giving you a predictable return on top of your electricity savings. Massachusetts does not enroll customers in SMART directly; an energy aggregator trades your credits as Class 1 RECs on your behalf, typically producing better returns than direct enrollment.

MassSave offers 0% interest loans over seven years specifically for heat pump installation. For homeowners considering whole-home electrification, this is significant: solar covers your electricity generation, and a heat pump replaces your oil, gas, or propane-fired heating system. Together, they can get a Massachusetts home to near-zero utility bills in under a decade — with the MassSave loan often covering the cost of the heat pump at no upfront cost and with no interest.

Net metering allows you to store excess generation as credits with your utility and draw on them when your panels aren’t producing. This is separate from the SMART program and applies broadly to solar customers statewide.

Is Solar Still Worth It Without the Federal Credit?

For owned systems — cash or loan — the financial case changed but didn’t collapse. Without the 30% credit, the return on a well-designed system in Massachusetts typically runs 10 to 15 percent annually, driven by electricity savings and the ongoing rise in utility rates. Massachusetts utility costs are among the highest in the country, and the two largest utilities carry significant debt that continues to push rates upward. Every year without solar is another year of financing that debt through your monthly bill.

For third-party-financed systems, the 30% benefit remains accessible — but structured differently than before 2026. The right product and the right installer matter enormously in this scenario.

For either path, the most important variable isn’t the incentive structure — it’s whether your specific home is a good candidate. Roof orientation, shading, electricity usage, and the accuracy of the production estimate your installer uses will determine more of your actual return than any tax credit ever will.

A Note on Who You Work With

One thing the current market makes clear: the difference between installers matters more than ever.

When the 30% credit applied automatically to every homeowner-purchased system, a bad installation could still pencil out financially. The credit absorbed a lot of mistakes. That's no longer the case. For homeowners who buy outright, the residential credit is gone.

For homeowners using third-party financing, the credit still exists, but it flows through the financing company, which means the terms of your agreement and the accuracy of your production model determine whether you actually see the benefit. Either way, the margin for error just got smaller. A system that underperforms its projections is no longer rescued by a tax credit. It's just a bad investment.

Great Sky Solar has operated since 2012 with a straightforward approach: model every home precisely, staff every job with full-time salaried employees rather than subcontractors, and assign a dedicated project manager to handle the roughly 65 hours of permits, utility applications, and coordination that a proper installation requires. We tell homeowners when solar doesn’t make sense for them. We’re not in the business of closing every conversation.

In a market that’s using confusion to its advantage, that approach matters.

What to Do Now

If you’re weighing a solar decision in 2026, the most useful thing you can do is get accurate information about your specific home before making any commitments.

That means understanding your roof’s production potential — not a law-of-averages estimate, but a precise model. It means understanding which financing path makes sense for your situation: an owned system, third-party financing, or waiting. And it means working with someone who will tell you the truth about the numbers, including if those numbers don’t make a compelling case.

The incentive landscape changed. The fundamentals of a good solar decision didn’t.
