Solar Takeoff Software: Auto-BOQ Guide 2026

Solar takeoff software is the tool an estimator uses to turn a finished design into a bill of quantities that procurement and the install crew can act on. The pain is well known. A residential job can swallow two hours of manual counting. A C&I bid can swallow a full day. Estimators tab through PDF drawings, tally modules, measure conduit on a screen ruler, guess at mounting hardware, and type it all into a spreadsheet that nobody trusts. The right solar takeoff software removes that step. It reads the design canvas, applies the hardware rules, and writes the BOQ automatically. SurgePV’s auto-BOQ does exactly this on every paid plan.

What a Solar Takeoff Includes

A complete solar takeoff is not a module count. It is the full procurement and labour list the project office needs to order materials, schedule crew, and price the bid. A useful takeoff lists every category below.

How SurgePV Auto-Generates the Takeoff

SurgePV treats the design canvas as the single source of truth. Every object on the canvas carries the catalog rules that govern its quantity. When the design changes, the BOQ changes.

When the design is locked, the platform writes the BOQ. Modules come from the array. Rail length comes from the row geometry. Clamp count comes from module count plus end clamps per row. DC cable length comes from the routed string paths set during string sizing. AC cable length comes from the run from inverter to the service panel. Conduit follows the routed paths with a configurable fill factor. Labour follows the editable rate table.

The result exports as a branded solar proposal PDF, an XLSX takeoff for the procurement team, and a DXF/DWG export for the install crew. The whole bundle drops out of a single canvas inside the solar design platform.

Solar Takeoff Software Across Tools

Most platforms market themselves as solar design software. Far fewer ship a true auto-takeoff. The table below compares the four most common tools an estimator will evaluate in 2026.

The pattern is clear. SurgePV bundles auto-takeoff and the export formats procurement actually uses into the base seat price. Competing platforms either add modules at extra cost or leave the takeoff partial. See the full breakdown on SurgePV pricing.

Real Example: 50 kW C&I Takeoff in 30 Seconds

Picture a 50 kW rooftop C&I project on a warehouse in Pune. The estimator imports the satellite image, draws the building footprint, sets the parapet height, and lets Clara AI place the array. The design takes under twenty minutes.

When the estimator clicks Generate BOQ, this is what drops out, in under thirty seconds.

• 92 modules at 545 W, monocrystalline bifacial, plus 2 spares.
• 1 string inverter at 50 kW, three-phase, six MPPT inputs.
• 184 meters of mounting rail, 6063-T6 aluminium.
• 188 mid clamps and 16 end clamps to suit a 35 mm frame.
• 24 L-feet and flashings rated for the metal deck.
• 92 pairs of MC4 connectors and 320 meters of 4 sq mm DC cable.
• 80 meters of 16 sq mm AC cable from inverter to the LT panel.
• 110 meters of 32 mm UV-rated conduit with eight sweeps.
• 1 DC isolator at 1,000 V DC and 1 AC isolator at 63 A.
• 1 monitoring gateway, 1 irradiance sensor, 1 module temperature sensor.
• 96 hours of mounting labour, 24 hours of wiring, 8 hours of commissioning.
• A contingency line at 3 percent for breakage and offcuts.

The same export carries the shade report, the yield estimate, the proposal PDF, the single line diagram, and the DXF for the install crew. The estimator never opened a spreadsheet.

Common Takeoff Mistakes

The bids that lose money rarely lose on module pricing. They lose on the lines the estimator forgot. The five most common misses.

1. Missing labour. The BOQ lists every part and zero hours. The crew shows up on day one and the margin is gone by lunchtime.
2. Forgetting AC cable to the meter. The DC side is detailed and the AC run to the service panel is left blank. On a long warehouse roof that single line can swing the bid by tens of thousands of rupees.
3. Wrong mounting count. End clamps are not mid clamps. Splices are not free. Counting one clamp per module instead of one per module plus end clamps per row understates the hardware by ten to fifteen percent.
4. Missing spare parts. Modules break in transit. MC4 connectors get crushed. A spare allowance of two to three percent protects the install schedule.
5. No contingency. Cable offcuts, breakage, weather delays. A two to three percent contingency line keeps the project office honest with the buyer.

Auto-takeoff does not eliminate judgment. It does eliminate the lines that get skipped because the estimator was tired.

Integration With Procurement and CRM

The takeoff lives downstream of design and upstream of procurement. SurgePV exports the BOQ as CSV, which means it slots into any ERP, any inventory system, and most quoting tools without a custom integration. Teams that want a clean handoff to a buyer-facing quote often pair SurgePV with QuickEstimate to turn the BOQ into a customer-ready price sheet without re-typing line items.

For sales workflows, the same export feeds the CRM. Deal stage, BOQ version, and quoted price stay aligned. When the engineer revises the design, the auto-BOQ updates and the CRM pulls the new total. That is the loop most teams describe as the difference between bidding ten jobs a week and bidding fifty.

Who Should Choose Each Tool

A few honest recommendations based on the shape of the team.

• Solo installer or two-person residential shop. Pick a tool with a fast residential flow and a clean proposal PDF. SurgePV Individual at 1,899 dollars per year fits if you also bid the occasional C&I roof.

• Three to five person mixed residential and C&I team. SurgePV at 1,299 to 1,499 dollars per seat is the sweet spot. Auto-BOQ, shade, and DXF export are included on every seat.

• Residential-only retail sales floor with light engineering. OpenSolar is a reasonable starting point, but most teams outgrow the BOQ depth within a year.

• Utility-scale only. Use a dedicated utility-scale tool. SurgePV is built for residential and C&I rooftop and carport work up to multi-megawatt jobs.

For most installer teams in 2026, the math is simple. Pick the solar design software that ships auto-takeoff, hardware neutrality, and export formats your procurement team already uses. That short list is short for a reason.
