What a Solar PV Takeoff Delivers
A contractor-ready spreadsheet organized by system — panels by array, inverters with specs, racking by type, conduit by size. The format your supplier and estimating software expect.
- Panel counts by array with wattage and string configuration
- Inverter and combiner box schedules with specifications
- Racking quantities and conduit footage by size
How the AI Reads Solar Plans
The AI reads your site plan, electrical one-line diagram, racking layout, and spec sheets together — understanding array configuration, string sizing, inverter connections, and conduit routing the way a solar estimator would.
- Reads site plan, one-line diagram, and racking layout together
- Understands string sizing and array configuration from one-line
- Conduit routing traced from inverters to point of interconnection
Every Trade. One Platform.

Solar Contractors Who Use It
Solar installers and electrical contractors doing commercial PV who needed takeoff speed on large projects.
6 reviews
"Ground-mount system, 2 MW. The AI caught the difference between the racking spec for section A and section B — different ballast configs. Flagged it. That would have been an expensive mistake."
"I do the electrical work on solar installs — inverters, conduit, interconnection. The AI organizes the conduit by DC vs AC runs automatically. Saves me 2 hours of sorting."
"Use it to verify sub bids. Caught a 20% undercount on a recent electrical sub package. Paid for a month of credits on that one catch. Now I run every sub bid through it before signing."
"Sprinkler layouts are complex — density zones, obstruction calcs, riser diagrams. The AI catches head counts and pipe footage I'd need hours to verify manually. Especially useful on large commercial projects."
"No subscription is the key for me. I pay credits when I bid, not monthly whether I use it or not. Slow months cost me nothing. Busy months I load up credits at the 10-pack rate and save 25%."
Solar PV Takeoff — Contractor Questions
Honest answers to what solar installers and electrical contractors ask before their first solar PV takeoff.
What does a solar PV takeoff include?
Panels by array and string, inverters and combiners with specs, racking by type and footage, DC and AC conduit by size, wire quantities by conductor, grounding system, rapid shutdown devices, and monitoring equipment.
- Panels, inverters, combiners, racking, conduit, wire
- Grounding, rapid shutdown, monitoring equipment
Does it work on commercial rooftop and ground-mount?
Yes — both. Rooftop plans include roof penetration hardware and flashing quantities. Ground-mount plans include pile or ballast counts by array section. The mounting type is identified from the racking drawing and spec section.
- Rooftop: penetration hardware and flashing quantities
- Ground-mount: pile or ballast counts by array section
How long does it actually take?
About 15 minutes for a typical 30-page commercial set. Larger plan sets — 80-100 pages — run 25-40 minutes. You'll get an email when results are ready. Upload before lunch, have counts before you leave the office.
- 30 pages: ~15 minutes
- Email notification when complete — no waiting at the screen
What exactly do I get back?
An Excel spreadsheet (or CSV) organized by trade category — circuits, devices, wire footage by gauge, conduit runs with sizing. The same format you'd hand to a supplier or import into your estimating software. Plus a flagged items list with page references.
- Excel, CSV, or JSON — your choice
- Organized by category, ready to import or price
How do I get started?
Create a free account with one Google click and we’ll show you a real commercial plan set alongside the AI-generated takeoff from it. See the output format, accuracy, and how flagged items work — before uploading any of your own plans. No credit card required.
- One Google click — no credit card required
- See a real example plan and takeoff output immediately
I already use PlanSwift / Bluebeam. Will this replace it?
No — and we're not trying to. TakeoffBuilder handles the counting. Your existing software handles pricing, markup, and workflow. We export to the formats your software imports. Think of it as a counting layer on top of what you already use.
- Exports to PlanSwift, Accubid, and Excel
- Complements your existing tools — doesn't replace them
