Solar Panel Permit Cost in 2026: $50 to $919.75 for the Same Array
A residential solar array runs roughly $15,000 to permit against, and the permit itself is the smallest, most wildly variable line on the whole project. The same array costs $50 to permit in Denver and $919.75 in Minneapolis. That is an 18x spread, set by each city's fee architecture, not by the panels or the sun. The permit is also not what makes solar slow. Utility interconnection review and the AHJ (authority having jurisdiction) inspection are the calendar. The fee is just the toll.
Full disclosure: the dataset and the calculator below are mine. I read these fee schedules for a living, and the numbers here come from the documents the cities publish, not from installer quotes or industry averages.
What 29 Cities Charge to Permit Solar
Here is what a sample of the tracked cities charge to permit the same $15,000 residential array.
| City | Permit fee | Share of a $15,000 array |
|---|---|---|
| Denver, CO | $50.00 | 0.3% |
| Nashville, TN | $107.50 | 0.7% |
| Tampa, FL | $124.00 | 0.8% |
| Atlanta, GA | $175.00 | 1.2% |
| New York, NY | $193.75 | 1.3% |
| Chicago, IL | $225.00 | 1.5% |
| Orlando, FL | $244.96 | 1.6% |
| Charlotte, NC | $321.61 | 2.1% |
| Seattle, WA | $466.40 | 3.1% |
| Los Angeles, CA | $497.75 | 3.3% |
| Phoenix, AZ | $706.00 | 4.7% |
| Minneapolis, MN | $919.75 | 6.1% |
The median city is New York at $193.75. Half the 29 cities charge less than that, half charge more. The mean is $278.09, pulled up by the few high cities at the bottom of the table. Even the worst case, Minneapolis, is 6.1% of the array, and the median sits well under 2%. This table shows 12 of the 29 cities, chosen to span the full range. The other 17 land somewhere between these markers.
The Fee Tracks the Schedule, Not the Sunshine
You might expect the sunniest cities to charge the most, since that is where solar pays off fastest and demand runs hottest. They do not. Phoenix and Los Angeles, two of the strongest solar markets in the country, sit near the top at $706 and $497.75. Denver, also sunny, is the cheapest in the set at $50. Sun does not set the fee. What sets it is how each city wrote its schedule. Some price a solar permit off the system's declared value, so a bigger or pricier array pays more. Some charge a flat electrical-plus-building fee that ignores size entirely. Some bundle a structural review of the roof attachment into the cost, because mounting panels loads the rafters. Minneapolis at $919.75 is not pricing more panels than Denver. It is pricing more review.
The Permit Is Not What Makes Solar Slow
The permit fee is a one-time charge you pay and forget. The calendar lives somewhere else. Two approvals gate a solar project. The first is the building and electrical permit from the city, which is the fee in the table above. The second is the interconnection agreement from your utility, the document that lets your system back-feed power onto the grid. The utility review runs on its own clock, answers to nobody at city hall, and often outlasts the permit by weeks. Plan review and a final inspection by the AHJ both sit between you and permission to operate, and both take time the fee schedule says nothing about. So the number people fixate on, the permit cost, is the part that resolves quickest. The timeline is where solar projects actually stall. Budget for the wait, not just the toll.
How to Read the Solar Line in Your Installer's Bid
A reputable solar installer pulls the permit and files the interconnection paperwork for you, and lists the permit as its own line on the bid. That is the tell. A bid that folds "permits and fees" into one lump is hiding a number you can look up yourself, and a number you can look up is a number worth checking. So check it. Run your city and system size through the calculator at the calculator, or pull the raw schedule from your city's page, where every figure links straight to the source document it came from. If the line on your bid is close to what the schedule says, the installer is being straight with you. If it is double, ask why.
Frequently Asked Questions
Do I need a permit to install solar panels?
Yes, in every city in the dataset. Rooftop solar adds electrical load to your service and bolts hardware to your roof, so it needs an electrical permit and usually a building permit too, plus the separate interconnection approval from your utility. None of the 29 cities tracked here exempt a residential install.
How much is a solar permit?
It runs $50 to $919.75 across the cities tracked, with a median of $193.75, measured against a roughly $15,000 array. Your city's fee schedule sets the exact figure. Either way it lands as a small fraction of the total install, usually under 2%.
Does a bigger solar system cost more to permit?
Sometimes. Cities that price the permit off declared system value scale the fee up as the system gets bigger or more expensive. Flat-fee cities charge the same regardless of size. Either way the permit stays a low single-digit percentage of the project, so size your system for your roof and your load, not for the permit line.
