Comparison Table
EasySolar
SMBWeb-based solar design and sales software with system sizing and production calculation features.
Scenario reruns tie layout changes to energy yield deltas inside one report workflow.
EasySolar is built for iterative PV design where inputs like module configuration, orientation, and shading context change and yield updates follow quickly. The workflow emphasizes practical PV design outputs such as energy yield summaries, loss breakdowns, and report-style deliverables that teams can reuse across revisions. The integration depth is most relevant when projects need consistent repeatability, since the same configuration can be rerun to compare scenarios.
A key tradeoff is that deep engineering verification workflows that require PVsyst PAN file parity, extensive bespoke electrical studies, or full IEC-grade electrical test planning may need external tools. EasySolar fits teams that want faster early-stage scenario comparisons for rooftops and small sites, then use a separate stack for final electrical engineering and grid-interconnection dossiers.
- +Browser-first simulation workflow for rapid PV design iteration
- +Loss-aware energy yield outputs support revision-to-revision comparisons
- +Report-style deliverables help standardize client and internal review
- –Limited coverage for full PVsyst PAN and report parity workflows
- –Advanced electrical engineering deliverables still need external tooling

Most failures stem from inconsistent scenario assumptions, scene geometry accuracy, or expecting estimator-style modeling to cover electrical edge cases.
Relying on scene-based shading outputs without validating horizon shading geometry and asset placement
Arka 360 depends on correct shading geometry and asset placement for model accuracy, so incorrect 3D positioning can distort energy yield results. Polysun also ties scene-based horizon and shading inputs to POA irradiance, so geometry mistakes propagate into loss attribution.
Changing layout assumptions across runs without keeping scenario management comparable
EasySolar ties layout changes to energy yield deltas inside one report workflow, so teams should use its scenario reruns to preserve comparability rather than rebuilding models from scratch. Scanifly keeps scenario alternatives comparable from first input through final yield reporting, so teams should avoid mixing ad hoc edits across separate scenarios.
Expecting estimator-first workflows to cover string-level electrical design and protection studies
OpenSolar is not focused on deep electrical design detail like string-level inverter loading, so external electrical tooling is needed for those studies. Solargis Evaluator also fits less for string-level electrical design and protection studies, so electrical verification must be handled elsewhere.
Assuming full PVsyst PAN and report parity workflows without checking model workflow coverage
EasySolar shows limited coverage for full PVsyst PAN and report parity workflows, so teams that need PVsyst PAN parity should plan an external handling path. PVcase can require external model handling for advanced PVsyst PAN style workflows, so teams should confirm the handling approach before standardizing a pipeline.
Using advanced modeling options without input discipline that keeps assumptions consistent
Scanifly flags that advanced modeling options require careful setup to avoid inconsistent assumptions, so standardized scenario templates reduce drift.
