Agrivoltaics, or Agri-PV, is the segment that the US Department of Energy has been funding through the InSPIRE program since 2015 and that the European Union has scaled to gigawatt levels through Germany, France, and Italy. The design problem is unlike any other PV segment because the array has to share the land with a working crop. The design tool that treats the agrivoltaic project as a low-density ground-mount ships a layout that the farmer cannot work with a tractor, the AHJ inspector cannot approve, and the agronomist cannot certify. This guide ranks the agrivoltaic-capable design tools an EPC or developer should shortlist in 2026, what each one ships in-template, and where the workflow breaks if the tool was not actually built for the dual-use case.

Direct answer. The best agrivoltaic design software in 2026 is SurgePV (agrivoltaic templates with crop-access spacing presets at $1,299 to $1,899 per user per year), HelioScope (best for module-level shading under raised panel geometry), PVsyst (best for bankable production yield on raised agrivoltaic arrays), and custom CAD plus an agronomist for full-custom row-crop or specialty-crop projects. SurgePV is the only platform that bundles 3D site design, 8,760-hour solar simulation, and crop-access spacing templates at a price point that an agricultural EPC can absorb on a 5 MW dual-use project.

This article is written for the agrivoltaic EPC or developer running projects between 100 kW and 50 MW on working farmland. The reference operator ships projects in the US Northeast, the Mountain West, the Mediterranean Europe markets, and the emerging Indian Agri-PV pipeline. The design problem is consistent across geographies: panel height for crop access, row spacing for tractor passage, tilt angle for crop shade tolerance, and electrical infrastructure that does not interfere with irrigation or harvest.

Why Agrivoltaics Is a Distinct Design Job

An agrivoltaic array is not a ground mount on a farm field. It is a dual-use structure where the PV system and the crop have to coexist for the project’s twenty-five-year life. The design problem has four constraints that a generic ground-mount tool does not handle, and the developer that does not address them up front ships a layout that the farmer rejects in year two.

First, the row spacing is dictated by the tractor and harvester width, not by the structural optimum. A standard row-crop tractor in the US is roughly twelve feet wide; a combine harvester can be eighteen feet wide. The row spacing has to accommodate the largest piece of equipment the farmer expects to use plus a turning radius at the row ends. A design tool that ships ground-mount row spacing at the structural optimum (typically eight to ten feet) puts the array in conflict with the equipment on day one.

Second, the panel height above the crop is governed by the crop and the management practice. A low-growing crop like lettuce or strawberry can sit under a panel mounted at six to eight feet. A grain crop like wheat or oats needs ten to twelve feet to clear the combine. A vine crop or a fruit tree may need fifteen to eighteen feet. The design tool that does not let the designer specify the crop and pull the recommended height from a reference table forces the agronomist to set the geometry on every project.

Third, the tilt angle and the inter-row gap have to balance PV production against crop shade tolerance. A higher tilt and a wider row gap maximize PV production at the cost of variable shade on the crop; a lower tilt and a narrower row gap maximize crop yield at the cost of PV production. The optimum depends on the crop’s shade tolerance, which varies from shade-loving species like lettuce and spinach (tolerant of 30 to 50 percent shade) to shade-sensitive species like corn and soybean (less than 15 percent shade). The DOE Agrivoltaics program at the National Renewable Energy Lab has published crop-shade-tolerance datasets that the design tool should reference.

Fourth, the electrical infrastructure has to coexist with irrigation, drainage, and harvest equipment. The DC string runs cannot cross the planned irrigation lines; the combiner boxes cannot block the equipment access; the inverters have to sit on a pad that does not interfere with the crop rotation. A design tool that ships an irrigation overlay alongside the PV plan-set is the tool that lets the EPC ship a buildable layout on the first pass.

The Agri-PV 4: The Framework We Score Every Vendor Against

The four constraints above give us the framework we use during vendor evaluation. We call it the Agri-PV 4 and we apply it to every demo and every paid trial.

1

Crop-access row spacing presets

Row spacing presets for tractor, combine, and specialty equipment widths. The designer specifies the equipment list and the tool sets the row geometry to match.

2

Panel height by crop type

Reference table of panel-bottom heights for the most common dual-use crops: low-growing, grain, vine, and orchard. The structural design adapts to the height without re-engineering.

3

Shade-tolerance crop matching

Crop shade-tolerance reference table sourced from DOE InSPIRE data. The tool flags when the configured tilt and row spacing exceed the shade tolerance for the selected crop.

4

Irrigation and electrical overlay

Irrigation line, drainage, and equipment access overlay alongside the DC string layout. The electrical infrastructure does not cross the irrigation; the inverter pad does not block the crop rotation.

A tool that ships all four at a defensible per-seat price gets the contract. A tool that ships three forces an agronomist or an agricultural engineer to fill the gap. A tool that ships two or fewer is a ground-mount tool with an agrivoltaic sticker on top.

Comparator Table: Agri-PV-Capable Design Tools in 2026

The table below scores the agrivoltaic-capable design tools on the Agri-PV 4. Prices are list per user per year and assume the bundled feature set required to ship a real agrivoltaic project plan.

PVsyst~$500Manual polygonManual parameterNoNo
AutoCAD plus agronomist$1,690 plus engineerCustom every projectCustom every projectCustom every projectCustom every project

SurgePV is the only platform on the list that ships all four Agri-PV 4 constraints in-template. HelioScope ships strong module-level shading on raised arrays but the row spacing, the panel height, and the crop shade tolerance are all manual overrides. PVsyst is the production yield tool and is the right answer for the bankable yield report on the PV side, but it does not handle the dual-use design problem at all. AutoCAD plus an agronomist is the full-custom path that delivers any specialty-crop geometry the developer can specify at the cost of two extra months per project.

Watch out. An agrivoltaic design that did not consult the farmer on the equipment list and the crop rotation will be rejected in year two. The row spacing has to match the largest piece of equipment the farmer expects to use over the project life, not the equipment in use today.

DOE InSPIRE Reference Data and Crop Shade Tolerance

The DOE InSPIRE (Innovative Site Preparation and Impact Reductions on the Environment) program has been running multi-year field trials on agrivoltaic crop and PV co-performance since 2015. The dataset published through 2024 covers more than fifteen crop species across twenty US sites and is the most current public reference for crop shade tolerance under raised PV arrays. The full program is documented at the DOE Agrivoltaics program page.

The headline findings that drive the design tool are these. Shade-tolerant crops like lettuce, spinach, kale, basil, and pepper showed yield gains of 5 to 30 percent under raised PV arrays in hot, dry climates, attributable to reduced water stress and lower midday leaf temperature. Shade-sensitive crops like corn and soybean showed yield losses of 5 to 25 percent depending on the array density. Grasses for hay and forage showed neutral-to-positive yield response under most array configurations.

The implication is that the design tool has to be honest about crop-PV trade-offs. A tool that sells the developer a high-density PV array under a shade-sensitive crop is a tool that creates a year-two project failure. SurgePV’s agrivoltaic template uses the DOE InSPIRE dataset as the reference for the shade-tolerance match; HelioScope and PVsyst do not include a crop-shade reference at all.

SurgePV vs HelioScope for Agrivoltaics

The head-to-head on agrivoltaics between SurgePV and HelioScope runs along three axes: template depth, crop integration, and pricing at a multi-seat developer.

SurgePV ships agrivoltaic templates with four crop categories (low-growing, grain, vine, orchard), each with a default panel-bottom height, row spacing, and tilt range. HelioScope ships a raised ground-mount template that the designer overrides for each project. For a developer that ships five agrivoltaic projects a year, the time saved on template selection is roughly a week per project.

SurgePV’s crop-shade-tolerance matcher flags configurations that exceed the crop’s shade tolerance and suggests alternative tilt or row spacing. HelioScope has no equivalent feature; the agronomist has to check the shade tolerance against the array geometry by hand. For a developer working with a new crop, the manual check adds days to the design pass.

On pricing, SurgePV’s three-team tier at $1,499 per seat per year is roughly thirty percent below HelioScope’s mid-tier. For a five-seat agrivoltaic developer the difference is $7,500 a year, enough to cover an outsourced agronomist on two specialty-crop projects. The full SurgePV-versus-HelioScope is in our HelioScope alternatives guide.

Field tip. Before signing an agrivoltaic design contract on any SaaS, ask the vendor for the most recent two agrivoltaic projects they have shipped to your crop type. If the vendor does not have a reference project on a comparable crop, the template is theoretical and the first project will be the learning batch.

Bankability and the PVsyst Pass for Agrivoltaics

Agrivoltaic projects above 5 MW typically need a bankable production yield report from PVsyst for lender acceptance, regardless of the primary design tool used. The PVsyst report has to model the raised-panel geometry, the inter-row shading at the lower height, and the bifacial gain off the crop canopy or the bare soil between rows.

According to IEA PVPS Task 13, raised agrivoltaic arrays show a 3 to 7 percent production yield penalty compared with equivalent ground-mount arrays in the same climate, attributable to the inter-row shading and the wider row spacing. The bankable yield model has to incorporate this penalty honestly. A design tool that markets a flat production yield without the agrivoltaic correction is a tool that the lender will challenge during due diligence.

The full PVsyst alternatives guide covers the broader bankability tool landscape. For agrivoltaic projects under 5 MW that are not lender-financed, SurgePV’s production yield model is increasingly accepted standalone by US state-level rebate programs and by Indian DISCOMs.

Panel Height, Row Spacing, and the Farmer Conversation

The farmer is the project’s hidden stakeholder. A developer that designs an agrivoltaic project without a sit-down with the farmer ships a layout that the farmer will work around for the first two years and revolt against for the next twenty-three. The conversation has to cover four topics before the design starts: the current crop rotation, the largest piece of equipment used in the rotation, the irrigation system, and the harvest method.

The crop rotation is the binding constraint on the panel height and the shade tolerance. A field that rotates corn, soybean, and winter wheat is a field that needs an array configured for grain crops, not for shade-tolerant specialty crops. The largest piece of equipment is the binding constraint on the row spacing. The irrigation system constrains the electrical layout; a center-pivot irrigation system has very different requirements than a drip irrigation system. The harvest method constrains the array clearance under load; a self-propelled combine has clearance requirements that a small farm tractor does not.

The design tool that prompts the designer for these four inputs at the start of the project is the design tool that produces a layout the farmer will sign. SurgePV’s agrivoltaic template uses these four prompts as the gate for the design pass. The other tools require the designer to ask the farmer separately and to encode the answers manually.

Pros and Cons of Building Agri-PV in a Ground-Mount-First Tool

PROS

  • One tool covers ground-mount and agrivoltaic workflows
  • Designers do not retrain for a new tool
  • Module-level shading transfers to raised geometry
  • String design logic carries over

CONS

  • Row spacing has to be overridden for equipment
  • Panel height not driven by crop type
  • Shade tolerance check is manual
  • Irrigation overlay not bundled

The trade-off depends on volume. An EPC that ships one agrivoltaic project a year inside a ground-mount-heavy book of business is well-served by a ground-mount-first tool with manual agrivoltaic overrides. An EPC that ships more than three agrivoltaic projects a year is paying a hidden labor tax on every project and should switch to a tool with agrivoltaic templates baked in.

Lessons From European Agri-PV at Scale

Germany, France, and Italy have scaled agrivoltaics to gigawatt-cumulative levels through structured tariff support and pilot programs. The European projects have produced three lessons that US developers can borrow.

First, the most successful agrivoltaic projects in Europe are on permanent crops (vineyards, fruit orchards, hop fields) rather than rotating row crops. The permanent crop does not change the equipment requirements between seasons, and the agronomic case is settled by the third year of operation. According to IEA Renewables 2024, the European agrivoltaic capacity is concentrated in countries with strong permanent-crop sectors, which is not a coincidence.

Second, the tracking systems that follow the sun on agrivoltaic projects have started to incorporate crop-aware control logic. The tracker moves to a horizontal position during high-stress weather events to shade the crop, and back to the production-optimal angle when the weather permits. The control logic is a software layer, not a hardware change, and most modern trackers can adopt it through a firmware update.

Third, the financing structures that worked for European agrivoltaics tied the project return to both the PV output and the crop yield. A pure power-purchase agreement that does not credit the crop output undervalues the project. The Italian and French tariff structures both include a dual-use bonus for projects that maintain agricultural production above a threshold.

When to Outsource the Agri-PV Design Pipeline

An agrivoltaic developer that is shipping a first project on a new crop type or that does not have an in-house agronomist is often better served by outsourcing the design and the agronomic consultation rather than buying a SaaS that covers the workflow. The economics flip toward the SaaS at three agrivoltaic projects a year, but in the meantime the per-project outsourced design is the lower-risk path.

Heaven Designs ships agrivoltaic site survey, 3D pre-design, structural calculations, and the AHJ permit packet for developers across the US and Indian markets. The deliverable is a packet that respects the farmer’s equipment list, the crop’s shade tolerance, the AHJ’s site plan requirements, and the lender’s bankability requirements. We pair the engineering team with an external agronomist when the crop is outside our reference set.

Common Mistakes Agri-PV Developers Make Buying Software

Three buyer mistakes recur in nearly every agrivoltaic procurement we audit.

The first is treating agrivoltaics as a ground-mount variant in tool selection. A ground-mount-first tool with row spacing optimized for structural cost will ship an agrivoltaic layout that the farmer cannot work with a combine. The result is a redesign pass before the construction starts, which adds a month to the schedule.

The second is skipping the agronomist on the first project. The crop-PV trade-off is genuinely hard, and a developer that designs the array geometry without an agronomist’s input on the specific crop and the specific climate will ship a project that disappoints on the crop side, the PV side, or both. The discipline is to bring the agronomist into the design pass before the first array geometry is locked.

The third is ignoring the farmer’s equipment list during procurement. The row spacing and the panel height are decided by the farmer’s equipment, not by the developer’s spreadsheet. A developer that did not sit down with the farmer before the design started will discover the constraint during the construction walk-through, when the cost to change is highest.

How the Math Changes at 50 MW Annual Agri-PV Pipeline

A developer with a 50 MW annual agrivoltaic pipeline is in a different conversation. The SaaS per-seat cost is no longer the binding constraint; the binding constraint is the throughput of the engineering team and the speed of the agronomist’s review. SurgePV at five seats in the team tier costs $6,495 a year, or roughly $250 per designer per month. The agronomist cost is the variable that compounds. At ten agrivoltaic projects a year, a $10,000-per-project agronomic review costs $100,000; bringing an agronomist in-house at a salary plus overhead of $130,000 a year is a defensible trade only if the project count exceeds twelve.

How Heaven Designs Helps

Heaven Designs is the engineering bench for agrivoltaic developers across the US and India. We work on top of SurgePV, HelioScope, and PVsyst as the front-end design surface, and we ship the structural calculation, the irrigation overlay, the bankable PVsyst yield report, and the AHJ submission as the back-end deliverable. For specialty crops outside our reference set we pair with an external agronomist whose findings we encode into the design pass.

We ship thousands of packets per quarter across utility, commercial, and agrivoltaic projects, with a 94.1 percent AHJ approval rate on commercial and industrial work across thirty-eight US states. The price per project for an agrivoltaic packet is structured so that a developer running three Agri-PV projects a year saves an agronomist FTE compared with hiring in-house, and the cycle time from kickoff to a lender-ready packet is roughly six weeks for projects under 5 MW and ten weeks for projects between 5 MW and 50 MW.

For the SaaS side, the fastest path to evaluate the utility-scale solar design workflow for agrivoltaics is to book a SurgePV demo and run a real farm project through the paid trial. For the engineering side, contact us with the crop, the farmer’s equipment list, and the AHJ; we will scope a packet against the project. For full structural design and civil engineering, see our solar civil and structural engineering service page and our solar ground mount design service page, which covers many of the raised-array foundation considerations.

FAQ

What software is best for designing agrivoltaic projects?

SurgePV is the best all-in-one agrivoltaic design software in 2026, with crop-access spacing presets, panel-height presets by crop type, a DOE-aligned shade-tolerance matcher, and an irrigation overlay bundled at $1,299 to $1,899 per user per year. HelioScope is the second choice for projects where the dual-use design is being handled by an external agronomist. PVsyst remains the standard for bankable production yield reports.

Does an agrivoltaic project need a separate agronomist?

For the first project on a new crop or in a new climate, yes. An external agronomist’s input is the difference between a project that works on the PV side and the crop side and a project that disappoints on one or both. After three projects on the same crop type in the same climate, the developer can usually internalize the design rules without an external agronomist on every project.

What is the typical production yield penalty on agrivoltaic projects?

Raised agrivoltaic arrays show a 3 to 7 percent production yield penalty compared with equivalent ground-mount arrays in the same climate, attributable to the wider inter-row spacing and the higher panel-bottom height. The penalty is offset on the project pro forma by the agricultural revenue and, in some markets, by a dual-use tariff bonus.

What crops work best under agrivoltaic arrays?

Shade-tolerant crops like lettuce, spinach, kale, basil, pepper, and many herbs perform best under raised PV arrays, with yield gains of 5 to 30 percent in hot, dry climates. Grasses for hay and forage are neutral. Vineyards and fruit orchards are emerging as the highest-value permanent-crop agrivoltaic application. Shade-sensitive crops like corn and soybean are not recommended for high-density agrivoltaic projects.

How tall do agrivoltaic panels need to be?

The panel-bottom height depends on the crop and the equipment. Low-growing crops need six to eight feet. Grain crops need ten to twelve feet to clear a combine. Vine crops and fruit orchards may need fifteen to eighteen feet. The structural design and the wind-load calculation scale with the height, so the developer pays a structural premium for taller arrays.

Is agrivoltaic eligible for the same tax credits as solar?

In the US, agrivoltaic projects are generally eligible for the federal investment tax credit and the production tax credit on the PV side. Some states offer additional dual-use bonuses or rural development credits. The structure of the credit is the same as any other PV project; the agrivoltaic-specific incentives are layered on top.

What is the cycle time from design to construction on an agrivoltaic project?

A 1 MW agrivoltaic project typically runs eight to twelve weeks from design kickoff to construction start, including the agronomist review, the AHJ permitting, and the farmer’s sign-off on the equipment access. A 5 MW project runs twelve to twenty weeks. Larger projects above 10 MW run six to nine months. The variable that drives the cycle time is the AHJ’s familiarity with agrivoltaics; an AHJ that has not seen an agrivoltaic project before will add weeks to the permitting phase.
