This is a broad gross-cost range, not a proposal. Equipment, labor, site conditions, financing, and current program terms can materially change it.

WHAT'S IN THE PRICE

Five things determine what you'll pay.

If a quote hides these, you can't compare it to anything.

01

System size

How much energy you use determines how many panels you need, the biggest single price factor.

↗
02

Your roof

Pitch, shade, condition, and layout affect both the design and the labor.

↗
03

Equipment

Panel and inverter choice, plus add-ons like batteries or EV charging, changes capability and cost.

↗
04

Site work

Electrical upgrades, structural work, or trenching for ground mounts add scope.

↗
05

Financing

Loan term, APR, and dealer fees can make the financed cost higher than the cash price.
