How payback works

Estimated payback

Saved per year
Solar's return is its payback period: annual bill savings against net system cost. In 2026, without the federal credit, that payback is longer but still real where rates and net metering are favorable.
Spot a fair quote in Lyman
A typical solar installation here runs $12,800–$16,700. A trustworthy quote shows a production estimate (kWh/year) and the net cost after incentives, not just a monthly payment. Be cautious of door-to-door pressure.
- Get the production estimate in kWh and the net cash price.
- Confirm the net-metering rate your utility currently pays.
- Compare buying vs lease/PPA; ownership keeps the long-run return.
What changes your price
- System size (kW). Sized to your annual usage and roof space; bigger arrays cost more but produce more.
- Panel tier & inverter. Premium high-efficiency panels and microinverters cost more per watt.
- Roof complexity. Steep, multi-plane, or shaded roofs add labor and may need more equipment.
- Battery storage. Adding storage roughly increases project cost by half but adds backup power and self-use value.

Why it matters
Why it pays to do it right
Lock in your electricity rate
Solar trades a volatile monthly bill for a fixed up-front cost, hedging against future utility rate increases over the system's life.
Payback is the real question
With the federal credit gone in 2026, the honest math is production times your local rate versus net cost. We show that payback plainly, no inflated promises.
Net metering rules drive the return
Where your utility still offers it, net metering credits the power you export, and that buyback rate is often the single biggest swing factor in your return. Several states have scaled it back, so confirm your utility's current policy.
Pairs with a sound roof
Panels last 25+ years, so install on a roof with plenty of life left. If your roof is near end-of-life, replace it first.
Local conditions
Solar in Mount Vernon
Rooftop solar in Lyman works, but the economics deserve an honest look. Puget Sound Energy's service territory sees only about 3.8 peak sun hours per day averaged annually, and PSE's rate of roughly 10 cents per kWh means the bill you're offsetting is modest. A typical Mount Vernon system produces around 1,050 kWh per installed kW per year. Paybacks commonly run 18 to 25 years here, and the 30% federal credit expired at the end of 2025, so 2026 cash buyers should model carefully before committing.
Peak sun hours
~3.8/day
Heavy Pacific cloud cover limits production; a south-facing roof with no shading is essential to extract maximum output.
PSE rate
~10¢/kWh
A lower rate means a smaller nominal bill to offset, which stretches payback compared with higher-rate markets.
Annual output
~1,050 kWh/kW
Expected production per installed kW in the Mount Vernon climate; lower than inland or southern markets due to cloud cover.
Incentives & net metering
Washington's net metering law (RCW 80.60) requires Puget Sound Energy to credit excess solar production at the retail rate and apply it to future bills, which is the strongest possible credit structure. The 30% federal 25D credit expired December 31, 2025, so 2026 cash buyers get $0 federal credit; leases or PPAs can tap the business 48E credit through 2027. With 3.8 peak sun hours and a 10-cent rate, a 6 kW system offsets only a modest portion of a typical annual bill, and the breakeven horizon is long. The math is most favorable for south-facing roofs with minimal shading and for homeowners planning to add an EV or heat pump to increase their own load.
Permits
Rooftop solar in Lyman requires a building permit, electrical permit, and PSE interconnection approval.
FAQ
Solar questions, answered for Lyman
Is solar worth installing in Lyman's cloudy climate?
It can be, but payback is long. With roughly 3.8 peak sun hours and a 10-cent rate, most Lyman systems pay back in 18 to 25 years. The 30% federal 25D credit expired at the end of 2025, so a 2026 cash purchase no longer shortens that; adding an EV or heat pump to increase your own consumption makes the math better. Run the numbers carefully before committing.
How does net metering work with PSE in Mount Vernon?
Washington's net metering law requires Puget Sound Energy to credit excess solar production at the retail rate and apply the credits to future bills. This is the strongest credit structure possible, but with a 10-cent rate the credits are modest in absolute dollar terms.
What is the federal solar tax credit for Lyman homeowners?
The 30% residential solar credit (Section 25D) expired December 31, 2025, with no phase-down, so a 2026 cash purchase across Lyman gets $0 federal credit. The strongest lever now is PSE's retail-rate net metering. Leases or PPAs can use the business 48E credit through 2027.
What roof orientation works best for solar in Lyman?
South-facing at a pitch of 20 to 35 degrees maximizes annual production in the Mount Vernon climate. Southwest is nearly as good. North-facing panels produce roughly half the output of south-facing ones here and rarely pencil out; get a site-specific shading analysis before committing.
