CF2R-SRA-01-E: The Solar Ready Certificate Explained
CF2R-SRA-01-E is the installation certificate for a new single-family home's solar-ready provisions. It comes into play in a subdivision of ten or more residences when the home has no rooftop solar, often because an exception applies. SRA-02-E adds the solar zone area worksheet, and STH-01-E covers solar water heating.

When a builder meets this form
The solar-ready provisions are mandatory for single-family homes without photovoltaics in subdivisions of ten or more residences. Many skip PV because an exception to the prescriptive PV requirement applies, and that is when the solar-ready paperwork is asked for.
Three forms, three jobs
- CF2R-SRA-01-E documents what was installed to meet solar readiness, including equipment installed to qualify for an exception.
- CF2R-SRA-02-E is the minimum solar zone area worksheet, needed only when the home keeps a solar zone.
- CF2R-STH-01-E applies when solar readiness is met by installing a solar water heating system.
What the solar zone route puts on the plans
- A zone of at least 250 square feet on the roof or overhang, and on steep roofs facing between 90 and 300 degrees of true north.
- No vents, chimneys or equipment inside the zone, and roof dead and live loads shown on the construction documents.
- A reserved spot for inverter and meter, plus a conduit pathway.
- A main panel with a 200-amp minimum busbar and a reserved double-pole breaker space marked "For Future Solar Electric".
The occupant is also to receive a copy of those documents (Section 110.10(d)).
What the six exceptions do
They differ. Exceptions 2, 3 and 5 shrink the zone to 150 square feet, Exception 4 asks for half of the potential zone area, and Exceptions 1 and 6 swap in other measures such as solar water heating at a 0.50 solar savings fraction or demand-responsive thermostats paired with an additional measure. The manual says zone requirements fall away under an exception, but the Standards text for several still calls for a smaller zone, so read the exact exception being claimed.
Where PV forms take over
When PV is installed, CF2R-PVB-01-E documents the system against the CF1R and PVB-02-E does the same for battery storage. The rule behind all this is explained in solar-ready requirements and solar exemptions for a new home, with the wider picture in residential solar requirements. For form families see the CF2R page and forms by discipline; our residential service prepares the CF1R.

Frequently Asked Questions
The mandatory provisions cover single-family homes without PV in subdivisions of ten or more residences, so a lone custom lot is usually outside them. Your department confirms.
The person responsible for the installation signs it, like any certificate of installation, and the form carries the building permit number.
