What Is SolarAPP+

Standardized
Plan Review
Software

In 2021, the National Renewable Energy Laboratory launched a collaborative effort with key code officials, authorities having jurisdiction, and the solar industry to develop standardized plan review software that can run compliance checks and process building permit approvals for eligible rooftop solar systems.

SolarAPP+ is developed and maintained by the National Renewable Energy Laboratory (NREL) in partnership with code officials and the solar industry. Learn more at solarapp.nrel.gov →

The Process

How SolarAPP+
Works

📋
Submit System Plans

Solar installers enter project details and system specifications into the SolarAPP+ platform — no paper forms, no mailing plans to a counter.

🤖
Automated Compliance Check

The platform runs the design against applicable building and electrical codes instantly, flagging any issues before a permit is issued.

🏛️
Permit Approved & Issued

Compliant systems receive permit approval automatically — sometimes in minutes rather than days or weeks — so installation can begin sooner.

🔍
Inspection & Final Sign-Off

After installation, SolarAPP+ provides a standardized inspection checklist, streamlining the inspector's job and closing out the permit cleanly.
