One of the quiet wins for Fresno solar customers in the past few years has been the City of Fresno's adoption of SolarAPP+ — the SunShot Initiative-developed automated permit platform that replaced multi-week city plan review for most residential solar projects with same-day or next-day approval.
If you are installing solar in the City of Fresno in 2026, this is what the SolarAPP+ process looks like and why it matters.
What Is SolarAPP+?
SolarAPP+ (Solar Automated Permit Processing Plus) is an instant-permit platform built by the U.S. Department of Energy's National Renewable Energy Laboratory (NREL) in partnership with leading authorities having jurisdiction (AHJs).
Instead of submitting a paper permit application that sits in a city plan-review queue for 2-6 weeks, qualifying solar projects are submitted through the SolarAPP+ portal, the system automatically checks code compliance, and the permit is issued — typically the same day.
The City of Fresno has been a SolarAPP+ adopter since 2021. For qualifying residential solar systems, this has cut Fresno project timelines by roughly 3-5 weeks vs the legacy review process.
Which Fresno Projects Qualify for SolarAPP+?
SolarAPP+ works for the vast majority of residential rooftop solar installs in Fresno, with a few exclusions. Qualifying projects must:
- Be residential only (1-2 family dwellings)
- Use a standard rooftop mounting system (no ground mount, no tracker, no carport)
- Use listed inverters and panels from a pre-approved database
- Be on a 2017 or newer Fresno electrical code building
- Have no battery storage (battery-included projects use a separate process)
- Be on a service panel that already has spare capacity (no panel upgrade required in scope)
Projects that do not qualify (battery storage, panel upgrades, ground mount, carport, commercial):
- Use the legacy City of Fresno plan review process (2-4 weeks typical)
- Still much faster than many other Central Valley AHJs
How NMS Handles the SolarAPP+ Submission
The submission is technical — code-compliance modeling, structural calculations, electrical single-line diagrams, panel and inverter spec sheets. NMS handles every step on the homeowner's behalf:
- Design package: Our engineering team prepares the full SolarAPP+ submission including roof structural analysis, electrical SLD, racking layout, and equipment data sheets.
- Submission: We submit through the SolarAPP+ portal as part of the City of Fresno permit application.
- Same-day approval: For qualifying projects, the permit is typically issued within hours of submission.
- Pay the City fees: We pay the City of Fresno permit fee on your behalf (included in our quoted price — no surprise add-ons).
- Build: With permit in hand, we can schedule install immediately. No 4-week wait.
What the Old Process Looked Like (Pre-SolarAPP+)
For context on how big a deal this is:
- Submit paper permit application to City of Fresno
- Pay permit fee
- Wait 2-6 weeks for plan reviewer to get to it
- Receive plan reviewer comments (almost always something to fix)
- Resubmit with corrections
- Wait another 1-3 weeks
- Receive approval
- Schedule install
The pre-SolarAPP+ process routinely added a month to project timelines — and that month was pure dead time for the homeowner. SolarAPP+ collapses it to a day for most residential projects.
What About Battery-Included Projects?
Battery storage (Tesla Powerwall, Enphase IQ, FranklinWH) is excluded from SolarAPP+. Battery-included projects use the City of Fresno's legacy residential plan review. In Fresno, this typically runs 2-4 weeks — still faster than many surrounding jurisdictions but slower than the SolarAPP+ instant track.
If your priority is speed-to-PTO, solar-only with battery added later (as a "storage-only addition") can be a faster path. We will walk you through the trade-offs on the design call.
The Other Cities
Not every Central Valley city has adopted SolarAPP+:
- Clovis: Uses its own electronic permit portal with typically 1-2 week turnaround. Not SolarAPP+ but reasonable.
- Madera: Legacy plan review process, 2-3 weeks typical.
- Visalia: Mixed; depends on project type.
- Fresno County (unincorporated): SolarAPP+ available for many residential projects since 2022.
- Foothill jurisdictions (Auberry, Tollhouse, Oakhurst): Legacy process, often slower due to high-fire-zone reviews.
NMS handles permitting for every AHJ in the Central Valley. We know what each one wants and how to get a clean approval.
Total Project Timeline With SolarAPP+
For a typical Fresno residential solar-only install:
- Design + survey: 1 week
- SolarAPP+ permit: same day
- Install: 1-2 days
- City inspection: 1-2 weeks
- PG&E PTO: 2-4 weeks
- Total: 4-7 weeks from signed agreement to system operating
For battery-included projects on legacy review, add 2-3 weeks to the front end.
Why It Matters
A faster install timeline means:
- Earlier first month of PG&E bill savings
- ITC eligibility for whichever tax year your PTO falls into
- One fewer summer of paying full PG&E rates while waiting
Pre-SolarAPP+, a homeowner who signed in February might not be saving on PG&E until July. Post-SolarAPP+, the same homeowner can be operating by mid-April — capturing two extra months of California sun and savings.
