If you’re considering installing solar panels on your home in 2026, there’s one thing you need to understand right away: the solar industry landscape has changed significantly this year. The old rules around federal tax credits no longer apply, so relying on information from 2025 or earlier could lead you to a costly mistake. Here are the 7 most important things every U.S. homeowner should know before going solar in 2026.
1. The Federal 30% Tax Credit Has Expired
This is the biggest change heading into 2026. Under the “One Big Beautiful Bill Act,” the 30% federal tax credit for homeowner-owned residential solar systems under Section 25D expired on December 31, 2025. If your system is being installed in 2026 and you’re purchasing it outright with cash or a loan, you will not receive this credit — no matter what a salesperson tells you. Eligibility depends on your system’s Permission to Operate (PTO) date, not the date you signed your contract.
2. Leases and PPAs Still Offer a Path to Tax Savings
Here’s the good news: if you don’t buy the system outright but instead use a lease or Power Purchase Agreement (PPA) with a third-party-owned solar setup, that third-party company can still claim the 30% commercial credit under Section 48E, and those savings are often passed on to you through lower monthly payments. This benefit remains available as long as the system is placed in service by December 31, 2027 — making it a potentially more attractive option than buying outright in 2026.
3. Don’t Stop at Federal Incentives — Check State and Local Programs Too
Just because the federal credit is gone doesn’t mean every incentive has disappeared. Many states still run their own rebates, property tax exemptions, and net metering programs. Before installing solar panels, check with your state energy office or utility company for a full list of local incentives, as these can meaningfully offset your costs.
4. Your Ownership Model Matters More Than Ever
In 2026, deciding whether to buy or lease/PPA your solar panels is more important than ever:
- Buying (cash/loan): You own the system outright and see greater long-term savings, but you no longer get any federal tax credit.
- Lease/PPA: Lower upfront cost, and the third-party owner claims the tax credit — but your long-term savings are typically smaller.
Base your decision on your financial situation and how long you plan to stay in your home.
5. Your Payback Period May Be Longer Now
With the tax credit gone, the effective upfront cost of solar panels has increased, which directly impacts your payback period — the time it takes for your electricity savings to cover the installation cost. Ask your solar company for a clear breakdown of your actual payback period without the tax credit, and compare it against your current electricity rates and expected rate increases.
6. Consider Pairing Solar Panels with Battery Storage
If your area experiences frequent power outages or has weak net metering rates, it’s worth considering battery storage alongside your solar panels. A battery lets you store excess energy generated during the day and use it in the evening or at night, reducing your dependence on the grid. Battery systems add to your overall budget, so ask your installer for a separate ROI breakdown for the battery.
7. Choosing the Right Installer Is More Critical Than Ever
With the safety net of the tax credit gone, choosing a reliable, experienced installer has become critical. Make sure to:
- Confirm the installer is licensed and insured in your state
- Get multiple quotes to compare equipment brands, warranties, and pricing
- Ask the installer to clearly explain the ownership model (buy vs. lease/PPA) without any misleading tax credit claims
- Check reviews and ask for references
Final Thoughts
Installing solar panels in 2026 can still be a smart long-term investment, but the decision now hinges on more than just a tax credit — it comes down to electricity bill savings, ownership model, state incentives, and installer quality. Keeping these 7 factors in mind will help you make an informed decision and choose the right solar panel solution for your home.
