Each PVcase product covers its stage in depth, and each is a separate purchase, interface and hand-off. The expensive part of C&I design is rarely the first layout; it is the reconciliation when the layout, the electrical calculations and the yield model live in different files and drift apart. PVcase also keeps layout iteration inside AutoCAD, so every designer who changes a layout needs a CAD seat to do it.
- Pre-CAD design
- Pre-CAD design is the stage where layout, equipment selection and yield are decided before a project enters CAD for construction documentation. It is the stage that sets the cost basis of the project, because changing a design in CAD costs sharply more than changing it before drafting starts.
Where they win
Terrain-heavy ground mount is PVcase's home ground, and the depth that matters there is civil. Ground Mount reads your survey terrain, grades the site with cut-and-fill heatmaps and draws cross sections, all inside the DWG your drafters already use. Solesca places trackers and tables on terrain and simulates them, but it does not grade a site, so if your engineering runs on Autodesk tooling end to end and your output is a construction drawing set, PVcase fits that shape better than a browser platform does.
Prospect is a siting product in its own right: 400+ map layers, parcel and landowner records, zoning, hosting capacity and grid injection studies. Solesca's screening layers cover slope, wetlands, canopy and the grid, so a developer whose bottleneck is finding land gets further with Prospect. Ground Mount also designs AC- and DC-coupled battery storage, which neither Solesca license includes, and both PVcase layout products export a single-line diagram, where Solesca's comes with the plan set add-on.
On layout over terrain the two are level: both place trackers and fixed-tilt tables on the ground as found. On simulation the difference is where it runs. Solesca simulates each frame in the engine that placed it; PVcase simulates terrain in Yield, a separate product.
One thing to discount in either direction: the PVsyst hand-off. Solesca exports a native PVC file, and PVcase added PVC 2.0 export to Ground Mount in August 2026. Both land your geometry in PVsyst without a rebuild, so neither vendor holds an edge worth switching over.
Do you need AutoCAD to design solar?
With PVcase, for layout work, yes. Ground Mount and Roof Mount run inside AutoCAD on Windows, and PVcase's published system requirements list AutoCAD 2019 through 2027 and state that the plugins will not run on virtual machines. Every designer who lays out a site needs a seat of both.
- Ground Mount or Roof MountThe PVcase layout plugin
- An AutoCAD seatVersions 2019 to 2027
- A Windows desktopThe plugins will not run on virtual machines
Energy modeling is PVcase Yield and site selection is PVcase Prospect, each a separate product.
- A Solesca licenseLayout, shading and yield on either license
- Any machine with a browserNothing to install
Layouts export to editable DXF, so the drawing still reaches CAD for construction documents.
With Solesca, no. Design runs in the browser on the machines your team already uses, and layouts export to editable DXF, so your CAD team picks the drawing up in the tool they know. CAD keeps its place, which is construction documentation. The question is whether every iteration before that stage should cost a CAD seat.
What should you require in a PVcase alternative?
Six checks separate the candidates for rooftop work, and they are worth settling before any demo. Here they are with Solesca's answer to each. Hold any vendor, this one included, to the same six.
- 01
Layout that does not take a CAD seat per designer
Design runs in a browser tab on the machines your team already has.
- 02
Obstruction handling with setbacks you control
ARGUS AI reads the rooftop image and returns HVAC units, skylights, wires and drains in seconds.
- 03
Simulation with validation a lender accepts
DNV SolarFarmer runs inside the platform, and Solesca’s simulation agrees with PVsyst to within 1%.
- 04
A route from layout to the permit-ready drawings
Plan sets and SLDs come as an add-on, with the Electric Stamp at market rate through SOL Credits.
- 05
DXF your CAD team can open and edit
Every layout exports to editable, layered DXF.
- 06
Screening that costs nothing per site
Neither license counts projects, so a rooftop team can model many roofs to build a few.
Which PVcase alternatives are worth evaluating?
The shortlist follows your deliverable, not your preference. Solesca fits C&I and community solar teams whose output is the interconnection package: browser-based, unmetered, layout through bankable simulation to the drawing set.
HelioScope fits a small commercial team that wants a lower entry price and storage design, which it includes on every tier; weigh that against its allowance of 10 projects a month and 120 a year per license, and a 5 MW DC ceiling on Pro. PVsyst is the simulation of record rather than a layout tool, so a team that only needs the financeable model can buy PVsyst on its own. Residential teams belong on Aurora rather than on anything else named here.
What does leaving AutoCAD cost a rooftop team?
Count the switching costs honestly. Your drafting standards, title blocks and details live in CAD templates that took years to build, and your drafters' fluency is in AutoCAD, not in a new interface. Neither cost disappears because a license is cheaper.
The move that keeps both is to leave CAD where it earns its seat, construction documentation, and stop spending it on iteration. Solesca layouts export to editable DXF, so the drawing lands back in the tool your drafters know, and because Solesca does not meter, running it beside PVcase during your current term uses no allowance. Bring one roof you are working on now, model it in both, and hand the PVsyst comparison to whoever signs your drawings.
Common questions
Does Solesca require AutoCAD?
No. Solesca runs in the browser, and layouts export to DXF so a CAD team can pick the drawing up in the tool they already use.
Can we design commercial rooftops without AutoCAD?
Yes. Solesca runs in the browser, ARGUS AI detects rooftop obstructions such as HVAC units, skylights, wires and drains and applies the setbacks you specify, and finished layouts export to editable DXF, so construction documentation stays in the CAD tool your team already uses.
Does PVcase require AutoCAD?
For layout work, yes. PVcase Ground Mount and Roof Mount run inside AutoCAD on Windows, per the published system requirements, which also state the plugins will not run on virtual machines. PVcase Prospect and PVcase Yield are cloud products.
Does PVcase Roof Mount run on a Mac or a virtual machine?
No. PVcase publishes system requirements for Roof Mount and Ground Mount that specify Windows 10 (x64) with AutoCAD 2019 through 2027, and state that the plugins will not run on virtual machines.
Does PVcase produce a single-line diagram or a plan set?
PVcase Ground Mount and Roof Mount both export a single-line diagram, and PVcase describes Roof Mount’s string plans and wiring layouts as permit-ready documentation. Neither its product pages nor its help center list a plan set package with a site plan and an equipment settings sheet, or a stamp. Solesca produces all three sheets as the plan set add-on to the Engineering License.
Does Solesca stamp plan sets?
No. Solesca produces the plan set as an add-on to the Engineering License. The Electric Stamp is a market-rate service through a licensed PE partner, bought with SOL Credits, and an engineer of record signs the drawings.
Does Solesca offer storage design?
Neither Solesca license includes storage design. PVcase Ground Mount designs AC- and DC-coupled battery storage, standalone or with PV, so if your projects are storage-led, PVcase covers something Solesca does not.
Can both export to PVsyst?
Yes. Solesca exports a native PVC file, and PVcase added PVC 2.0 export to Ground Mount in August 2026, covering project geometry. The PVsyst hand-off is not a meaningful difference between the two.
Which is more accurate, Solesca or PVcase Yield?
Solesca validates within 1% of PVsyst, corroborated by ECA Power’s published case study, and holds an NREL CRADA (CRD-23-23746). We have not evaluated PVcase Yield and do not claim an accuracy edge over it.
How much does PVcase cost in 2026?
PVcase publishes plan names but no prices: Prospect comes in Essentials, Professional and Premium, Yield in Essentials and Professional, and Ground Mount and Roof Mount in Professional, each quoted on request. Budget an AutoCAD subscription per layout designer as well. Solesca publishes its license model rather than a price list, and neither of its licenses meters projects.
Can we run Solesca and PVcase in parallel?
Yes. Solesca does not meter projects, so a side-by-side on live sites during your current PVcase term consumes no allowance on the Solesca side. Most teams evaluate this way rather than switching cold.
Which PVcase alternative is right for our team?
It follows your deliverable. Solesca fits C&I and community solar teams, with a sweet spot of 100 kW to 10 MW, whose output is an interconnection package and who want no CAD seat per designer. HelioScope fits small commercial teams wanting a lower entry price and storage design. PVsyst is the simulation of record rather than a layout tool. Residential teams should look at Aurora. If your drafters work in AutoCAD all day and your deliverable is a construction DWG, staying on PVcase is the correct answer.
