Top 10 Best Solar Panel Design Software of 2026

Aurora Solar’s core loop starts with importing or defining a roof surface and then placing PV strings and inverters against that geometry. Shade analysis is built into the design flow so layout changes can immediately update production expectations. Electrical modeling supports string and inverter configuration so the design stays consistent through DC and AC layout steps.

A practical tradeoff is that deep electrical edge cases can require manual review outside the default layout assumptions. Aurora Solar fits best for organizations that need fast iterations on roof options and want consistent proposal outputs for recurring commercial and residential roof types.

OpenSolar is a fit for teams that need repeatable solar designs with fewer handoffs between layout, electrical, and reporting steps. The workflow centers on interactive placement of PV components and electrical grouping choices tied to the design canvas. Energy modeling can then reference the configured system so updates propagate through results and reports.

A tradeoff is that deeper electrical compliance workflows may require careful template setup and disciplined data entry before design output is considered final. OpenSolar is a strong match when a studio or installer team runs many similar residential or small commercial jobs and needs consistent outputs across designers.

PVcase is most compelling when design teams need repeatable steps from roof modeling to energy yield modeling, then a consistent path to deliverable exports. Shade handling and irradiance modeling feed energy yield prediction, and the layout workflow can map to string inverter configuration or microinverter layouts. Export support includes AutoCAD DWG for structural and placement deliverables, plus electrical single-line diagrams for electrical documentation.

A key tradeoff is that advanced electrical design details can require careful manual parameter choices to match local utility requirements. PVcase fits situations where teams produce frequent residential or light commercial variations and need a controlled workflow that turns layout changes into updated yield and documentation quickly.

Energy Toolbase targets solar project design workflows where electrical layout and engineering outputs are managed from within a single workspace. The tool focuses on plan creation and export packages that support downstream drafting and documentation needs.

It supports common PV design steps like module arrangement planning, string and inverter configuration, and layout documentation for roof-based installations. It also emphasizes repeatability through saved configurations that reduce rework when designs change.

SolarEdge Designer generates PV layouts and supporting electrical documentation inside a workflow aimed at SolarEdge projects. It pairs module and inverter placement with design checks that reflect SolarEdge system constraints, including string-level electrical configuration outputs.

Users can produce drawings such as single-line diagrams and export CAD deliverables like AutoCAD DWG for downstream drafting. The tool also supports shade and energy yield work by tying layout geometry to modeling assumptions used for design reporting.

Skelion targets solar design teams that need layout-to-electrical workflow support for residential and small commercial projects. It focuses on roof-aware PV placement workflows, project configuration, and exportable deliverables for downstream engineering and documentation.

The software is positioned for repeatable design runs where standard assumptions must stay consistent across revisions. Skelion’s value is strongest when the design process benefits from structured inputs that map into drawings and calculations used in proposal and permitting packages.

Scanifly focuses on end-to-end solar layout and permitting workflows tied to roof geometry, not just diagram creation. The workflow supports design iteration with single-line electrical output and structural mounting layouts driven by project inputs.

It also supports export paths used for downstream drawing sets, including CAD-oriented outputs for review packages. Compared with layout-only tools, Scanifly is distinct for keeping the mechanical site model and electrical configuration aligned through the same project build.

ARKA 360 is a solar panel design tool focused on turning roof and layout inputs into engineering-ready PV layouts and electrical outputs. It supports module placement workflows geared toward array configuration, including work that maps physical layout to inverter and circuit structure.

The software also targets obstruction-aware modeling for roofs so the downstream yield and design checks reflect real site geometry. ARKA 360 fits teams that need repeatable modeling output for project handoff rather than sketch-only concepting.

AutoCAD performs PV layouts by converting panel placement and mounting geometry into CAD-accurate drawings such as DWG sheets and details. It supports electrical single-line diagrams and conduit route drafting within the same DWG workflow, which helps coordinate mechanical and wiring views.

AutoCAD also fits solar projects that need LIDAR surface modeling inputs to drive accurate roof and terrain geometry for later shading checks or layout constraints. For energy yield and code-driven electrical engineering outputs, AutoCAD typically relies on external calculation workflows rather than native PV modeling engines.

SolarPlus is a solar panel design and layout workflow focused on producing engineering-ready diagrams and installation layouts. It supports roof-level placement planning tied to electrical design outputs such as string and inverter configurations for DC and AC interconnection sizing.

The workflow emphasizes configuration inputs that drive energy yield estimates and reportable single-line outputs for permit-style documentation. Its distinct value shows up when teams need consistent layouts across projects and repeatable documentation exports.
