Easy to get started

The growing solar market has increased workload on permitting offices nationwide, but typical solar panel systems have also become more common and consistent. SolarAPP+™ is able to streamline this process through an automated and standardized approval process.

Free for jurisdictions

SolarAPP+™ will always be offered to city and county permitting departments at no cost. After initial setup, jurisdictions are able to spend less time with common residential solar panel systems and can devote their resources to other critical needs.

Full support

After the initial onboarding, the system will operate without additional support from your team. SolarAPP+™ will continue to improve, and NREL will provide no-cost updates for code revisions and new technology as they come online.
