Permitting and interconnection

How solar permitting works in Allentown

Authority Having Jurisdiction (AHJ)

Permit office: City of Allentown Bureau of Building Standards and Safety (4th floor, 435 Hamilton St; online via Energov platform)
SolarAPP+ status: SolarAPP+: Not adopted by this AHJ
Permit fee: Allentown: online via Energov platform. Permit fee: greater of $75 or 1.5% of total project cost (materials plus labor), plus $4.50 state UCC fee. Example: $30,000 system = $450 + $4.50 = $454.50 permit fee. Typical review: 1-2 weeks for routine residential. PA-licensed PE stamp required. No SolarAPP+. PPL Level 1 residential interconnection: 2-4 weeks.
Typical contract-to-energization: 6 to 10 weeks (permit 1-2 weeks, PPL Level 1 interconnection 2-4 weeks)

We handle the permit and interconnection filings

LADBS permit application and plan set preparation
SolarAPP+ submission for qualifying systems
LADWP or SCE interconnection application
Inspection coordination and utility sign-off
Certificate of Completion delivery to homeowner

URGENCY: Allentown homeowners should start the solar process immediately if they want the best chance at PPL grandfathered net metering terms. Permitting takes 1-2 weeks; interconnection takes 2-4 weeks. The closer to the July 2026 effective date, the higher the risk of missing the grandfathering window. PPL grandfathering at PTC rate for 140 MW of projects is subject to PA PUC approval; the settlement terms may still change.

Allentown solar questions

What Allentown homeowners ask

City-specific answers. Every number references your utility and your permit office.

What is the PPL net metering change and why does it matter for Allentown?

PPL Electric filed a rate case in September 2025 proposing to shift from 1:1 retail net metering to hourly LMP-based credits, which would reduce export credit value by approximately 40-60%. The proposed settlement (filed March 13, 2026) for a $275M revenue increase includes 10-year grandfathering at the Price to Compare rate for 140 MW of projects. New distribution base rates are expected effective July 1, 2026. Allentown homeowners who have Permission to Operate before the new tariff takes effect may qualify for grandfathered 1:1 credits through December 31, 2036, subject to PA PUC approval.

How urgent is the PPL situation for Allentown solar buyers?

Very urgent for those who want to maximize solar economics under current net metering terms. Permitting in Allentown takes 1-2 weeks; PPL interconnection takes 2-4 weeks. Starting the process immediately gives the best chance of completing interconnection before the July 2026 effective date. The closer you are to the deadline, the higher the risk of missing the grandfathering window. Do not wait.

Does Pennsylvania have a solar sales tax or property tax exemption?

No. Pennsylvania applies the standard 6% sales tax to solar equipment and installation. On a $29,500 Allentown system, this adds approximately $1,770. There is no statewide property tax exemption for solar in PA. PA SRECs ($22-$40/SREC annually) and PPL net metering are the primary financial incentives.

What neighborhoods in Allentown and the Lehigh Valley are seeing solar growth?

South Allentown has established solar adoption among its working-class homeowner population with single-story homes that often have adequate south-facing roof space. In Bethlehem, the South Side and Northampton Heights are seeing active solar outreach from regional installers. Easton, across the Delaware River in Northampton County, falls within the same PPL territory and has similar economics. The Lehigh Valley Economic Development Corporation has clean energy financing resources for the region.

Is there a federal solar tax credit in 2026?

No. The Section 25D residential solar tax credit expired December 31, 2025. Active Allentown incentives: PPL 1:1 net metering (with July 2026 change pending - act now), PA SRECs ($22-$40/SREC annually), and PA HEELP loan for panel upgrades.
