Solar salespeople have one job: make the pitch sound inevitable. The honest answer to “are solar panels worth it?” is it depends — on three numbers specific to your house. This guide gives you those numbers and the math to decide for yourself, with no installer incentive attached.
The only three numbers that decide it
- Your electricity rate. At $0.30+/kWh (California, Northeast, Hawaii) solar pays back fast. At $0.10/kWh (cheap-hydro Pacific Northwest) it can take 15+ years.
- Your sun. Phoenix gets ~6.5 peak sun hours; Seattle ~3.8. Same panel produces nearly double the power in the first.
- Incentives. The federal 30% Residential Clean Energy Credit ended for systems placed in service after December 31, 2025 — 2026 installs get no federal credit. State and utility incentives still stack, and net-metering rules quietly make or break the economics.
Run all three for your address in the solar payback calculator and size the system in the solar panel sizing calculator.
When solar is clearly worth it
- High electricity rate (>$0.20/kWh) and decent sun. Payback frequently 6–10 years on a 25+ year system — strong return.
- Full retail net metering. Every exported kWh credits at the rate you’d pay. This is the single biggest economic lever.
- You own the system (cash or loan). Ownership keeps all the savings and any state/utility credits — the federal 30% credit no longer applies to 2026 installs either way. Payback typically lands well inside the panels’ warrantied life.
- You plan to stay 7+ years. Long enough to cross break-even and bank years of free production.
When solar is NOT worth it (or marginal)
- Cheap electricity (<$0.13/kWh) and average sun — payback can exceed 15 years; the money may work harder elsewhere.
- Low-credit net metering (NEM 3.0-style). Where exports credit at a fraction of retail, a big grid-export system is overbuilt. Size to daytime use plus a battery instead — see the offset input in the sizing calculator.
- Lease or PPA. The installer may still claim a separate commercial credit (Section 48E) on systems it owns, not you — and you sign a 20–25 year escalating contract. Far weaker economics than ownership; can also complicate a future home sale.
- You may move within a few years. Solar can add home value but does not reliably return its full cost at sale, especially if leased.
The lease/PPA trap
A lease or power-purchase agreement gets panels on your roof for $0 down — but any state credits typically go to the installer, not you, and you tie yourself to a 20+ year escalating contract. Buyers of your home may balk at assuming it. Ownership (cash or a solar loan) is almost always the stronger financial choice if you can swing it — and since the federal credit no longer favors ownership over leasing the way it did through 2025, the case for ownership now rests entirely on long-term cost and resale value. The calculators here assume ownership for that reason.
A realistic example
A home using 900 kWh/month in California (≈$0.30/kWh, 5.8 sun hours), 100% offset, ~16 panels / 6.4 kW:
- System cost ≈ $17,600 (no federal credit for 2026 installs — California’s 2026 state/utility incentives on top of this vary by program, check DSIRE)
- Annual bill offset ≈ $3,200
- Simple payback ≈ 4 years, then ~20+ years of largely free electricity.
Without the federal credit, that $17,600 system nets a simple payback closer to 6 years instead of 4 — still strong in a high-rate, high-sun market. The same system in a $0.11/kWh, 4.0-sun-hour market stretches well past 15 years. This is why a generic “yes solar is worth it” is useless. Your two numbers (rate, sun) decide it — run your own at the solar payback calculator, which reflects the federal credit’s expiration.
Don’t forget the EV / heat pump multiplier
If you add an EV or a heat pump within a few years, your electricity use jumps — and solar you sized to today’s usage suddenly covers far less. Size to 120–150% now if electrification is coming; adding panels later costs more per watt. Cross-check the load with the EV vs gas calculator and heat pump vs gas furnace calculator.
Frequently asked
What happened to the 30% solar tax credit? The federal Residential Clean Energy Credit (Section 25D) ended for systems placed in service after December 31, 2025, under the One Big Beautiful Bill Act. Systems installed in 2026 or later get no federal credit; systems placed in service by December 31, 2025 could still claim it on that year’s return. See our full solar tax credit guide.
Does solar add home value? Owned solar generally adds value; leased solar often does not and can deter buyers. The value added rarely equals the full cost, so treat resale as a bonus, not the payback plan.
How many panels do I need? Driven by your usage and sun hours, not house size. The sizing calculator gives the exact count from your bill.
What kills solar economics fastest? Cheap electricity and poor net-metering credit. Both shrink the savings per kWh you generate.
Decide in 5 minutes
- Grab a recent electricity bill (monthly $ and kWh).
- Run the solar payback calculator for your state.
- Size the system in the solar panel sizing calculator.
- If payback lands inside ~10 years and you’ll stay put, it is very likely worth it. If it stretches past 15, be skeptical of the pitch.
Solar is worth it for a lot of homes — and oversold to plenty where it isn’t. Your two numbers settle the argument in minutes.
