The short answer
Solar on a new home is cheapest to plan before the roof goes on: conduit, panel capacity and roof layout can be designed in.
In California the building energy code expands solar and battery requirements, with the 2022 code applying to permit applications from 1 January 2023.
Elsewhere it is optional, and you can use the builder’s package or your own installer.
Building with solar in mind
Roof orientation and conduit runs cost little now.
Its energy code sets solar and storage standards for new homes.
Check equipment, size and who warrants it.
Builder package or your own installer?
A builder package is convenient and permitted with the house. It may be sized only to meet code, not your usage. Using your own installer gives you choice but needs coordination with the builder’s schedule and warranty.
Ask whether the builder system is owned or leased, a question that also applies to resales: see pre-purchase inspection.

We are a research desk, not a sales floor. We read the statute, the tariff, the code section, the federal filing or the manufacturer data sheet ourselves, and we publish the figure with the document it came from and the date we retrieved it.
Where a number cannot be traced to a primary source, we publish the shorter page and say what we could not verify. That rule has cost us whole sections, and it is why the rest can be checked.
