::THE_MATH

Three Numbers That Change Everything

Solar economics reduce to three numbers. Your current bill. The savings solar produces against it. And what you actually keep paying. Every other figure on this site flows from these.

STEP 01
Your Current Bill
$0/mo

The monthly utility bill you pay today, on a $0.14/kWh national average.

STEP 02
Solar Offsets
−$0/mo

The portion replaced by your rooftop solar production over a 25-year system life.

STEP 03
Net Monthly Cost
$0/mo

What's left: small grid connection fees and minor draw on cloudy days.

::RESIDENTIAL_CREDIT_ENDED

Federal residential credit: $0.

The 30% federal residential solar credit has ended. Under P.L. 119-21, the §25D Residential Clean Energy Credit terminated for expenditures made after Dec 31, 2025 — a system installed in 2026 cannot claim it. So the honest question in 2026 is: does solar still pay in your state without the federal credit? Run the math with $0 federal credit plus your state's incentives.

::FOR_BUSINESSES · SECTION_48E

Run a business? Solar pays back faster.

Commercial solar is a different credit from the residential one that ended. Commonly cited Section 48E percentages and depreciation benefits are not a settled quote.

Commercial solar (§48E) is different — but the clock moved. Projects that missed the Jul 4, 2026 beginning-of-construction deadline generally must be placed in service by Dec 31, 2027. Figures on this page are general information, reviewed Oct 2026, not tax advice.

The federal residential credit is $0 for a 2026 install. What remains is state credit, net metering, SRECs, exemptions, and utility rebates.
