Solar & Storage Permit Data

Solar and storage permit data records distributed generation as it is authorized: photovoltaic system size, module and inverter counts, battery capacity, and EV charging. Builty structures these nationally at the address, dated from the permit that authorized the install.

Why permits

Every install at the address, as it is permitted

Interconnection queues and incentive filings are the usual sources for distributed generation, and both lag the physical work. A permit is pulled before the panels go up. It carries the system size, the equipment, and the address, which makes it the earliest structured record that a property is about to start generating.

A solar permit, decoded

Solar is frequently stacked with the electrical and roof work it requires.

FAQ

Frequently asked questions

Do solar installations require a permit?
Yes, in effectively all US jurisdictions. A photovoltaic install is electrical work and usually structural work as well, so it is permitted, and that permit is a public record.
Do you know the system size?
Where the permit states it, which is most of the time: kW DC, module count, and inverter configuration. Battery capacity is captured where storage is included.
How is this earlier than interconnection data?
A permit is pulled before installation. An interconnection record is created after it, once the utility approves the connection. The gap between the two is typically weeks to months.
Is EV charging included?
Yes, where charger circuits are permitted, often on the same record as a panel upgrade.
Can I scope this to one utility territory?
Yes. Delivery can be scoped to any set of jurisdictions or geographies, by API, bulk file, or ongoing feed.
