Comparison Table
Scanifly
vertical specialistSolar design and field data software using drone and 3D site capture.
Project-linked proposal document generation that preserves traceability from configuration inputs to client deliverables.
Scanifly’s core workflow centers on taking module and inverter configuration inputs, mapping them to a layout, and generating documentation tied to that configuration. It includes shading-related inputs and output artifacts that help standardize how teams capture assumptions across projects. Deliverables are grouped by project, which reduces rework when iterating through alternative layouts.
A key tradeoff is that deep, CAD-grade electrical design work still depends on external tooling for detailed drafting beyond what Scanifly emits. Scanifly fits best when teams need consistent proposal documentation and repeatable design assumptions rather than custom drawing pipelines.
- +Project-based document output keeps proposal versions tied to design inputs
- +Iterative design workflow reduces rework across layout and electrical configuration changes
- +Shading and irradiance assumptions are represented in the generated deliverables
- +Workspace organization supports multi-project queues for proposal teams
- –CAD-grade electrical drafting is limited versus dedicated electrical design tools
- –Automation depth depends on how teams structure inputs before running exports
- –Advanced custom data import can require process alignment across project setups

Best for: Fits when proposal teams need consistent solar design documentation tied to controlled assumptions.
Aurora Solar
vertical specialistSolar design and sales software for residential and commercial photovoltaic projects.
Customer proposal outputs and design artifacts stay synchronized during iterative roof and production modeling.
Aurora Solar is geared toward sales engineering teams that need fast iterations from initial roof fit to proposal-grade deliverables. The workflow centers on parcel and roof context, then runs energy production estimates with shading and orientation inputs to produce proposal-ready summary outputs. It also provides drawing and export artifacts that reduce manual rework when transitioning from design to permitting and procurement steps.
A practical tradeoff is that electrical detailing depth and engineering-grade control can depend on the specific project setup and imported constraints rather than fully mirroring a dedicated electrical engineering CAD flow. Aurora Solar fits best when project timelines reward rapid proposal turnaround and when standard design assumptions are acceptable for early-stage validation.
- +Proposal-ready outputs generated directly from the design workflow
- +Geospatial terrain and shading context used in production estimates
- +Exports support handoff to downstream project steps
- +Project configuration stays tied to design iterations
- –Electrical detailing can require careful setup to match engineering expectations
- –Some advanced constraints may need external inputs to stay consistent
- –Workflow changes can be costly once the design is heavily edited

Regional installers and EPCs
Standardized handoff from design to procurement
Lower handoff rework
Show 1 more scenario
Project managers
Design-to-permitting coordination
Cleaner internal review cycles
Structured deliverables help track what changed between design iterations before submission.
Best for: Fits when sales engineering teams need fast solar designs and proposal exports with consistent production estimates.
PVcase
enterprisePhotovoltaic design software for utility-scale and commercial solar projects.
Single-project workflow where design changes propagate into proposal-ready deliverables without rebuilding outputs.
PVcase centers on solar project design with inputs that support electrical configuration work and site constraints, then carries those results into proposal deliverables. The output set is geared toward commercial and residential sales cycles, including packaged documents derived from the underlying design. Teams get fewer handoffs because the proposal uses the same model context created during design. That reduces rework when geometry or electrical settings change.
A tradeoff appears in how teams adopt the workflow because proposal-ready outputs depend on staying inside PVcase’s modeling conventions during design. PVcase fits situations where a design desk supports multiple sales roles and needs repeatable turnaround for customer submittals. It is less ideal when project delivery requires deep integration with custom electrical rule engines or specialty formats outside PVcase’s export expectations.
- +Design outputs and proposal artifacts stay synchronized across changes
- +Shading-aware modeling reduces manual recalculation during revisions
- +Electrical configuration work feeds bill-of-materials style outputs
- +Project packaging supports faster internal review cycles
- –Workflow discipline is needed to keep proposal documents consistent
- –Export formats can limit downstream custom engineering toolchains
- –Advanced edge-case electrical designs may require extra manual handling
- –Collaboration controls depend on how projects are structured

Use the comparison table and detailed reviews above to validate the fit against your own requirements before committing to a tool.
How to Choose the Right Solar Pv Software
In solar pv software, the differences that matter show up in how well each tool connects design, documentation, and handoff—then keeps results consistent over updates. We look first at update frequency and import/export compatibility because those decide whether your workflows stay intact month to month.
Update frequency for PV libraries
Why it matters
Update frequency for PV libraries matters because module, inverter, and electrical assumptions change, and outdated component data can quietly skew outputs. If a tool refreshes component inputs reliably, you spend less time correcting old assumptions.
How to check
Ask for a changelog or release notes sample from the last 6–12 months and note whether component libraries were updated. In the demo, search for a recently released module or inverter; confirm you can select it and that the underlying spec matches the latest manufacturer datasheet.
Import/export compatibility for project files
Why it matters
Import/export compatibility decides whether you can reuse existing spreadsheets, CAD-derived electrical data, or template documents without rebuilding everything. In solar pv software, file handoff errors often become rework, not minor formatting fixes.
How to check
Request sample import of a BOM-style list or an exported spreadsheet and observe whether identifiers and quantities carry over correctly. Then run an export to the common formats the tool supports and check that the exported rows still map to the same component selections.
API and automation for recurring designs
Why it matters
API and automation for recurring designs matter because solar workflows rarely start from scratch; templates, repeat jobs, and internal approvals need controlled reruns. When automation is shallow, you end up copying settings and risking drift.
How to check
In the demo, ask whether there’s an API or at least a documented way to run repeatable tasks from outside the UI (batch runs, webhooks, or scripted exports).
Data model control for assumptions
Why it matters
Data model control for assumptions matters because solar results hinge on stored assumptions staying consistent from proposal to final paperwork. If the tool mixes assumptions between runs, you cannot audit what changed.
How to check
Open a project, then modify one assumption (for example, a component selection or electrical setting) and confirm which dependent outputs update. Check whether the tool keeps a clear record of assumptions per project and whether recalculation is deterministic.
Audit trail for revisions and exports
Why it matters
An audit trail for revisions and exports matters because solar projects move through approvals, and teams need traceability when numbers change. Without it, you cannot confidently explain why two documents disagree.
How to check
Create or load a small project and perform two edits, then export documents after each. Confirm you can view revision history with timestamps and show what changed (inputs vs outputs), and ask whether exports are linked to specific revision states.
Calculation transparency for PV outputs
Why it matters
Calculation transparency for PV outputs matters because solar pv software decisions often need justification for technical reviewers. When the tool shows where results come from, you can validate outputs instead of treating them as a black box.
How to check
In the demo, generate outputs and open the breakdown view to see which inputs drive the result. Change one input slightly and verify the tool’s breakdown updates in a way that matches expected directionality (for example, component selection changes reflect in the corresponding section).
Red flags
- Updates are infrequent, so new components don’t appear or specs look stale
- Imports lose identifiers, and exports don’t match the same component selections
- Revision history shows timestamps only, with no clear input/output linkage
Fit by situation
- If your team reuses the same job templates every month, prioritize API and automation for recurring designs.
- If you must reuse existing spreadsheets and exported project files, prioritize import/export compatibility for project files.
- If approvals require traceability between drafts, prioritize audit trail for revisions and exports.
