Fake Urgency Around Tax Credit, Tariff and Net Metering Deadlines
The federal tax credit is ending and tariffs are about to raise prices. If you don't sign this week, you'll miss out for good.
What's actually true
Some solar deadlines are real, but many benefit the company more than you. The homeowner tax credit already ended for systems installed after 2025. The deadlines still in play mostly affect lease and PPA providers' own tax credits, and none of them justify signing a contract you haven't checked.
Deadlines are effective sales tools because missing out feels worse than overpaying. In 2026, solar sellers have plenty of real policy dates to point to: tax credit cutoffs, tariffs and net metering changes. Some matter. But the deadline being cited often helps the company, not you, and it’s almost never a good reason to sign without comparing quotes and reading the contract.
The deadlines being used, and what they mean for you
As of October 2026:
| Deadline being cited | What’s true | Who it mainly affects |
|---|---|---|
| “The 30% tax credit is ending” | The homeowner credit (25D) already ended for systems installed after December 31, 2025. There’s nothing left to rush for on a cash or loan purchase | No one, for owned systems. A seller using this is misinformed or misleading you |
| Lease/PPA tax credit (48E) deadlines | Solar must have begun construction by July 4, 2026 or be placed in service by December 31, 2027 for the provider to claim the credit | The lease or PPA company. You benefit only if they pass savings through in your price |
| Tariffs | Section 232 polysilicon tariffs are reported to take effect December 4, 2026 | Equipment costs may rise, but installers’ existing inventory and pricing vary |
| California net billing lock | Customers with PTO from April 15, 2023 through December 31, 2027 get export prices locked for 9 years | California homeowners, for export credit stability |
| State incentive or net metering changes | Real in some states; check your state | Depends on the program |

Why the 48E deadline gets used on you
Since the homeowner credit ended, more companies are pushing leases and PPAs, because the provider can still claim a 30% federal credit. Getting systems placed in service before the provider’s deadline is worth a lot to the provider. That can create real pressure to sign, even if a lease or PPA isn’t right for you. If the provider is rushing because of its own credit, ask how much of that credit shows up in your price. See lease vs buy vs PPA vs loan.
A worked example
A rep says prices will jump 10% after the tariff date, so you should sign today. On an 8 kW system at $24,000, that’s a $2,400 “penalty” for waiting. Now compare: if signing today means accepting a financed quote with a 25% dealer fee instead of shopping, you’d pay $30,000 in principal for a system worth $24,000 cash. That’s a $6,000 cost to avoid a $2,400 risk that may not happen. Check any quote with the dealer fee calculator.
How it shows up in a quote or contract
- A proposal “valid until” a date a few days away.
- A line item for an incentive “if signed by” a date.
- A lease or PPA whose price depends on the provider claiming the tax credit, with no explanation of what happens if it doesn’t.
- Pressure to start work during your cancellation period. See cooling-off waiver.
Questions to ask
- “What exactly is the deadline, and where can I read about it?”
- “If I miss it, how much would my price change? Will you put that in writing?”
- “Does this deadline affect my tax credit, or yours?”
- “Does your lease or PPA price depend on you getting a federal credit? What if you don’t?”
- “Can I have a week to get other quotes?”
What to do
Take the time anyway. Get two or three more quotes, run them through the quote comparison tool, and check lease offers with the lease vs buy tool. Paste any deadline claim into the sales claim checker. If you already signed under pressure, check your cancellation window with the cancel solar contract tool.
If a seller told you that you’d get a 30% tax credit on a system installed in 2026, or invented a deadline, report it to the FTC at reportfraud.ftc.gov and your state attorney general.

"This Price Is Only Good Today"
Solar equipment and labor costs don't change overnight. A discount that disappears tomorrow was almost always built into a high starting price, and it exists to stop you from comparing quotes.
Quotes That Subtract the 30% Federal Tax Credit in 2026
The Section 25D homeowner credit does not apply to systems whose installation was completed after December 31, 2025. If you buy with cash or a loan in 2026, your federal credit is $0.
"Net Metering Is Guaranteed Forever"
Net metering is set by state law and utility regulators, and it changes often. Grandfathering usually lasts a fixed number of years, and many states and utilities have already moved new customers to net billing, where exported power earns far less than retail.
Pressure to Waive Your Right to Cancel
The FTC Cooling-Off Rule gives you 3 business days to cancel most sales made at your home, and some states add more, such as California's 5 business days for buyers 65 and older. Starting work right away or asking you to waive the right is a common way to discourage cancellation.
