Prince George’s County launches online solar permit platform in July
Licensed solar contractors will get a single online permit path in July, after Prince George’s County said homeowners were still facing separate building and electrical filings.
Prince George’s County will roll out SolarAPP+ in July, giving licensed contractors a single online path for standard residential rooftop solar and energy-storage permits. The platform will automate plan review and code checks, cutting the separate filings that have added time and paperwork for homeowners trying to put panels on their roofs.
The new system is meant to fit into the county’s broader shift to digital permitting. Prince George’s already uses Momentum as its main online permits and licensing platform and ePlan for electronic plan submission, so SolarAPP+ will plug into a process that has already moved away from paper-heavy reviews. Applicants previously had to submit separate building and electrical permits through the online system, a setup SolarAPP+ is designed to replace with one automated review.
The platform will be limited to licensed contractors working on standard residential rooftop solar and energy-storage systems. SolarAPP+ automates code-compliance checks tied to ICC-2021 Code, Prince George’s County Building Amendments Subtitle 4, and local regulations.
The launch comes after a tightening of local solar inspection rules. An Oct. 2, 2025 county notice updated third-party inspection guidelines so residential and commercial solar inspections must be handled by approved third-party inspectors, with each project requiring final certification from an approved third-party electrical inspector.
Prince George’s County has also been promoting solar through Solarize Prince George’s, a county-supported effort that connects residents with state-vetted installers, incentives, homeowner FAQs, contractor guidance and permitting support. County clean-energy pages list about 8% of county homes and businesses as already having clean and renewable energy projects installed, and the county is developing a solar siting tool through ArcGIS.
The U.S. Department of Energy funded SolarAPP+ through its Solar Energy Technologies Office in 2019 and launched it in 2021. Since then, it has been used in more than 62 communities, issued more than 22,000 permits and approved about 127,000 kilowatts. Maryland’s Energy Administration created a SolarAPP+ Implementation Grant Program to help local governments cover software integration and training costs, and Prince George’s was among the first Maryland jurisdictions to receive that support.
