Between 2023 and 2025, 34 companies pulled 3,929 permits for solar panels on homes in Philadelphia. Solar States pulled the most (339, or 9%), followed by Velocity Energy and Home Solutions (254) and Phoenix Business Solutions (154). Every company in the ranking was still pulling permits in 2025; installers that have since closed are left out.
This ranking counts residential solar permits issued in the city, not finished installations: a few permits are never completed, and the permit is filed by the licensed company doing the work, which is usually but not always the company that sold the system. Permit records don't include prices or whether a system is leased.

Comparing quotes in Philadelphia?
Divide each quote's total, before incentives, by the system size in watts. Ask at least three of the companies above to quote the same system size. Reject any 2026 quote that subtracts a 30% federal tax credit from a purchase: that credit ended in 2025.
How to check a solar quote →Home Solar in Philadelphia by the Numbers
Based on 4,025 residential solar permits issued in Philadelphia between 2023 and 2025, from the City of Philadelphia, Department of Licenses and Inspections's open data.
Home solar permits per year
2026: 283 permits in the records so far. The year isn't complete, so it isn't counted in the ranking.
Home Solar Across Pennsylvania
City permits record who installed each system, but not what it cost or whether it was leased. For that, here is the picture across Pennsylvania.
Utilities in Pennsylvania reported 101,201 homes with rooftop solar in July 2026, averaging 8.3 kW per home. That is 19,612 more than a year earlier (+24%). Pennsylvania ranks 14 of 44 states by homes with solar. Home batteries paired with those systems add up to 15 MW.
Homes with solar: U.S. Energy Information Administration, Form EIA-861M, net metering (homes enrolled in net metering or a similar program).
Solar Panel Repair in Philadelphia
When a system stops producing, the best first call is an established local company. The companies ranked above pulled permits in Philadelphia through 2025, so they know the equipment on local roofs. Many will service a system they didn't install, but not all — ask before you book, and expect a diagnostic fee.

Installers That Closed or Went Bankrupt in Philadelphia
Companies that have since closed, liquidated or filed for bankruptcy pulled 3,242 home solar permits in Philadelphia since 2019. They are left out of the ranking above. If one of them installed your system, its workmanship warranty is likely gone — but panel and inverter warranties come from the manufacturer and usually survive the installer.

Solar in Philadelphia: Common Questions
Who installs the most solar panels in Philadelphia?
In the three most recent complete years (2023–2025), Solar States pulled 339 permits for solar on homes in Philadelphia, more than any other company. Velocity Energy and Home Solutions (254) and Phoenix Business Solutions (154) came next. Volume shows local experience, not workmanship, so compare quotes and reviews before choosing.
Who repairs solar panels in Philadelphia?
Start with the companies in the ranking above: Solar States, Velocity Energy and Home Solutions and Phoenix Business Solutions did the most work here, and an installer that knows the equipment on local roofs can usually diagnose a fault faster. If your system was leased or is on a PPA, call the company you pay each month first — maintenance is normally its job.
Can I still get the federal solar tax credit in 2026?
Not as a homeowner buying the system: the 30% residential credit (Section 25D) ended on December 31, 2025. Be wary of any quote that still subtracts it from the price. See our 2026 solar tax credit guide for what's left.
What if my solar installer went out of business?
Your panels and inverters are still covered by their manufacturers' warranties; what you lose is the installer's workmanship and roof-leak warranty. If the system is leased or on a PPA, the company you pay each month is usually responsible for repairs, and any active company in the ranking can take over service. See the installers that closed in Philadelphia and what still works when an installer closes.
What do homeowners in Philadelphia pay for electricity?
Residential customers in Pennsylvania pay an average of 21.73¢ per kWh, 25% above the national average. The higher the rate, the faster solar pays for itself. Source: EIA, Electric Power Monthly, Table 5.6.A.
No company pays to be listed or to rank higher, and any ad on this site is labeled. Before you sign, confirm the contractor license, insurance and recent reviews, and get at least three quotes. If a company in Philadelphia has closed, moved or changed its phone number, tell us and we'll check it.
How This Ranking Works
Companies are ranked by the residential solar permits they pulled here in 2023–2025, counting one permit per address per year; each needs at least 10 permits and at least one in 2025. Closed or bankrupt companies are removed and listed separately. The count shows local experience, not workmanship or service.
