Calculators guess from your ZIP code. An engineer looks at your roof from satellite data, your twelve months of use and the panel you already eyed in the store — then builds the cart that actually fits.
You get one link with every part priced to the cent, a wiring diagram your installer or inspector can follow, and a delivery date we hold for a week while you decide.

Two fields, then attach a bill in the reply email. No calls unless you ask, and nothing is ordered until you check out.
Yes. The parts list, wiring diagram and permit pack cost nothing and carry no obligation. You only pay if you check out the cart.
Your email, your address and a recent power bill — a photo of it is fine. If you already picked a panel in the store, mention it and we design around it.
Usually one working day. Engineers work Mon–Sat, 7:00–19:00, and anything sent on a Sunday is answered Monday.
Yes. Swap any part before checkout and the engineer re-checks the cart. If a swap breaks the design, we tell you before you pay.
Yes — the Cabin kit starts at $2,190 and the same engineers size it from what you plan to run there.
The five questions people ask before they send a bill.
The same eight things go into every parts list, whether it ends up a cabin kit or a whole-home bundle.
Bundles drawn from a power bill and a roof photo — with what each family ordered and who fitted it.
