Top 10 Best Pv Solar Design Software of 2026

Aurora Solar maps the roof surface into placement zones, then runs electrical design decisions like string sizing and inverter sizing to produce a consistent bill of materials output. Shading and irradiance modeling are integrated into the design loop so layout edits update production estimates instead of requiring separate analysis work. Export options include construction drawing sets and IFC file export for downstream workflows. The integrated approach helps teams keep layout, losses, and equipment lists aligned during customer revision rounds.

A key tradeoff is that Aurora Solar’s modeling accuracy depends on input completeness for site context like roof obstructions and terrain detail, which can add time before first pass automation. Aurora Solar fits best when teams need fast iteration across multiple roof geometries with repeatable electrical assumptions. It also supports usage when sales engineers need to turn design edits into updated production numbers without rebuilding the project structure from scratch.

PV*SOL covers the core chain from photovoltaic array layout through module stringing, electrical design rules, and energy yield simulation with irradiance modeling. Shading inputs can be derived from horizon profile and roof obstruction mapping, and those shading effects feed downstream losses and yield outputs. Design results can be packaged into construction drawing sets and bills of materials so handoff from engineering to installation stays tied to the same assumptions.

A practical tradeoff is that PV*SOL’s strongest results depend on careful setup of site data and electrical assumptions before running production calculations. It fits best when teams run the same project type repeatedly and need consistent DC and AC configuration choices across iterative roof layouts.

Scanifly maps roof inputs into photovoltaic array layout with module placement controls and constraint handling for setbacks and roof obstructions. It then moves into electrical design rules for module string sizing and inverter sizing checks tied to the selected configuration. Output generation covers bill of materials and construction drawing set style exports, which reduces rework when construction documents are needed. Integration work is more practical than pure desktop modeling because exports align with downstream procurement and drawing workflows.

A key tradeoff is that Scanifly is strongest when designs can be expressed through its layout-to-electrical workflow rather than when users need deep, custom engineering logic at every step. The best usage fit is a design desk that iterates multiple roof layouts and quickly produces BOM and drawings for review. Complex edge cases that require heavy custom modeling of rare installation geometries may need additional manual steps outside the Scanifly workflow.

OpenSolar is a PV solar design and proposal tool focused on fast solar layouts, electrical sizing outputs, and client-facing documents. It supports roof modeling inputs, photovoltaic array layout planning, and energy yield simulation workflows that generate construction-ready deliverables.

The software also produces bill of materials outputs aligned to the selected module and stringing decisions, which reduces rework during iterative design reviews. OpenSolar’s workflow prioritizes end-to-end design to proposal handoff over deep electrical modeling customization.

EasySolar is a PV solar design tool that turns roof and system inputs into layout diagrams, stringing guidance, and electrical sizing outputs. It focuses on end-to-end plan generation, including shading-related geometry inputs and production estimation that feeds an annual yield view.

Outputs are packaged for construction-facing handoff with a bill of materials and exportable drawing artifacts. The differentiator is workflow fit for small to mid-size teams that need repeatable designs with minimal manual iteration between layout and electrical assumptions.

Solar Monkey is a PV solar design tool focused on turning site inputs into layout, stringing, and electrical sizing outputs for fast iteration. The workflow centers on photovoltaic array layout generation with module stringing and inverter sizing guidance, plus energy yield simulation that ties shading and irradiance assumptions to production estimates.

Solar Monkey also supports construction-oriented deliverables like bill of materials and exportable drawings packages, so design outputs can move into downstream documentation. Automation is geared toward repeatable project setups, with an interface that emphasizes configuration consistency across similar roof types.

SolarEdge Designer ties PV layout, stringing, and electrical design to SolarEdge inverter and optimizer assumptions, which narrows variance versus generic solar CAD tools. It supports module string design, DC voltage window checks, and MPPT allocation consistent with SolarEdge architectures, then generates construction-ready outputs for project teams.

The workflow emphasizes rule-constrained configuration across the electrical design loop, so teams can maintain consistency from early proposal geometry through BOM and drawing packages. Library-driven project generation reduces manual reconciliation compared with tools that leave equipment mapping as a late-stage step.

PVcase is a solar design package that generates fast layout and electrical outputs from a structured proposal workflow. It focuses on roof and site geometry inputs, array layout generation, and production-style electrical sizing checks to speed up concept-to-drawing cycles.

The tool also supports exportable outputs for downstream teams that need drawings, bill-of-materials style lists, and shareable project files. PVcase is best evaluated by how well its design workflow matches the needed handoff format for construction and engineering review.

SolarProof produces PV solar design outputs from a guided workflow that maps roof inputs to module layouts and bill of materials. It supports electrical configuration for module stringing and DC sizing, then generates construction-oriented deliverables such as a bill of materials and plan set outputs for customer and installer use.

The tool focuses on practical design iteration using solar resource inputs for an annual production estimate and loss assumptions that drive the energy yield view. SolarProof is most effective when a team wants one package from array layout through deliverable generation without stitching multiple authoring tools together.

ENPHASE Designer is an Enphase-focused PV design tool that centers module and inverter choices from the Enphase ecosystem. It generates roof layouts and electrical configuration for Enphase hardware, then produces documentation sets suitable for internal review and handoff.

The tool’s differentiator is tight coupling to Enphase component constraints such as inverter allocation and DC behavior assumptions. Output generation is designed around what Enphase installers need for Enphase-based projects rather than fully vendor-agnostic modeling.
