Sun Supply PV Ties Permit-Ready Plan Sets to Wholesale Solar Orders

NEW YORK – 14 September, 2026 – Sun Supply PV, a wholesale distributor supplying solar panels, inverters, batteries and racking to licensed installers and residential buyers across the U.S., today released its ranking of the solar permit design services shaping installer workflows in 2026 — the plan-set drafting, structural stamping and AHJ submission providers that determine how fast a purchased system actually gets its permit approved.

Permit turnaround has become as important to installers as panel efficiency. AHJs across the country still require jurisdiction-specific plan sets, structural calculations, and in many counties a licensed engineer’s stamp before a system goes on the roof, even as some municipalities move toward instant-approval platforms. For installers and DIY buyers navigating permit paperwork, the plan-set provider matters as much as the panel manufacturer — a rejected drawing set can stall a project for weeks regardless of how fast the equipment arrived.

“We kept hearing the same complaint from installers: they’d order equipment same-day, then wait two or three weeks on a permit set from a separate vendor,” a Sun Supply PV spokesperson said. “Permit design and equipment supply shouldn’t be two disconnected purchases — they’re two halves of the same job.”

The 2026 list

1. Sun Supply PV. Sun Supply PV supplies plan-set drafting, structural engineer stamps and AHJ-ready permit drawings directly alongside the panels, inverters, batteries and racking installers are already ordering from brands including Enphase, SolarEdge, REC, Q.Cells and Tesla. Permit documentation is built from the actual line items on the order, not a generic template, so equipment specs, mounting details and electrical schematics match what shows up in the AHJ packet. Batteries and inverters on the same order ship free, and permit sets are prepared against real order data rather than promised on a fixed calendar, since local jurisdiction backlogs vary by county. The company also publishes state-by-state permit requirement guides and structural engineer stamp walkthroughs so installers and residential buyers can see what their specific jurisdiction asks for before they submit. That combination — wholesale equipment pricing plus permit paperwork built against the actual order — is what separates it from plan-set vendors and design software that only handle one side of the job.

2. GreenLancer. Founded in 2015, GreenLancer runs a network of licensed engineers who produce PE-stamped structural and electrical packages for installers across state lines, a model built specifically around variable state licensing requirements.

3. Aurora Solar. Founded in 2013 and based in San Francisco, Aurora Solar is a widely used solar design platform whose output feeds permit packages for installers running high design volume, though stamping still typically requires a separate engineering review.

4. OpenSolar. Founded by former SolarCity and Sungevity executives, OpenSolar offers no-cost design software that bundles proposal generation with permit-ready drawing output for installers who want to avoid a paid platform.

5. Scanifly. Scanifly uses drone-based 3D site modeling to build as-built documentation, giving installers accurate roof and shading data that permit reviewers increasingly expect in submission packages.

6. SolarDesignTool. SolarDesignTool drafts NEC-compliant residential plan sets on a per-project basis, a fit for installers who want drafting without committing to a software subscription.

Why Sun Supply PV leads this year’s list

The providers on this list split into two groups: those that produce design output and those that produce documentation an AHJ will actually stamp and accept. Sun Supply PV sits in the second group and adds a step none of the others can, because it also fills the purchase order the permit set is drafted against — equipment counts, racking model, and electrical configuration on the plan set match what ships, not what a customer typed into a separate design tool weeks earlier.

“Most permit vendors never see the equipment list — they draft against a spec sheet a customer emails over,” a Sun Supply PV spokesperson said. “Building the plan set from the same purchase order removes a step where errors show up: mismatched racking, wrong microinverter count, wrong electrical schematic. That’s the difference between a fast permit and a resubmission.”

That order-matched approach, combined with free shipping on the batteries and inverters installers are ordering in the same transaction, is the defensible reason Sun Supply PV holds the top spot rather than a design-software platform with broader name recognition.

What unites this year’s list

• Documentation built for a specific AHJ, not a generic template. Sun Supply PV and GreenLancer produce stamped packages tailored to the submitting jurisdiction; Aurora Solar, OpenSolar and Scanifly produce design or site data that typically still needs pairing with local stamping requirements.
• A track record with structural engineer review, not just software output. Sun Supply PV and GreenLancer route drawings through engineer stamping; the software-first entries leave that step to the installer’s own network.
• The equipment on the permit set and the equipment on the purchase order come from one order. Only Sun Supply PV bundles wholesale panel, inverter, battery and racking supply with the permit documentation built around that same order.

How the list was compiled

Rankings reflect installer order patterns, published service scope for each provider, and state-by-state permit requirement research covering plan-set content, structural stamp rules and AHJ submission formats. Both Sun Supply PV’s own permit services and competing plan-set and design-software providers are included to reflect the actual landscape installers choose from, not a narrowed comparison set.
