Top 10 Best Solar Layout Software of 2026

PV*SOL is built around a design canvas that couples roof segmentation with electrical layout steps like string sizing and inverter selection. The workflow keeps modeling inputs and results connected, so layout edits propagate into yield and configuration outputs. Shade and irradiance handling is integrated into the same session, which reduces the need for separate assumptions when iterating on obstruction and placement.

A key tradeoff is that deep CAD-like roof authoring is not its primary strength, so complex structural edits often require preparing clean roof geometry elsewhere. PV*SOL works best when installers already have roof segments and want fast iterations on module placement, string topology, and yield reporting without switching tools.

EasySolar is geared toward producing roof-level layouts that teams can refine during site planning, including repeatable segmentation of roof surfaces. Its interactive placement workflow is designed around placement rules and layout iteration, which helps reduce time spent redrawing when spacing or roof boundaries shift. CAD export supports handoff into design and drafting pipelines, which matters when detail work happens outside the layout tool.

A key tradeoff is that advanced energy modeling depth and granular electrical design controls are less central than the layout and CAD handoff path. EasySolar works best when the team’s next step depends on geometry-driven drawings and clearer roof coverage plans rather than full engineering-grade simulation. A common usage situation is multi-roof projects where installers need consistent layouts across parcels and must deliver drawings quickly to procurement or structural review.

archelios Pro is built around a layout-first workflow that maps PV placement onto roof segmentation and project elements so edits propagate through subsequent outputs. Design work typically covers string and interconnection sizing inputs and then produces drawing artifacts suitable for handoff to CAD-based teams. The tool’s documentation focus shows up in how it structures sheets and exports that designers can reuse across revision cycles.

A practical tradeoff is that the strongest results depend on clean starting geometry and disciplined layer setup before layout rules run. It fits best when the design team owns standardized roof models and expects consistent output formats for a repeatable pipeline.

Polysun is a solar layout and design tool used to produce site-ready system configurations with strong layout-to-analysis continuity. It supports roof segmentation workflows, obstruction inputs, and energy yield simulation in one design loop.

The software also centers on PV-specific CAD interoperability with exports aimed at downstream tools that consume PV layouts. Polysun fits teams that need repeatable layout generation tied to simulation assumptions rather than disconnected drawing-only outputs.

ARKA 360 produces PV layout outputs that installers can turn into CAD-ready plan sets for roof and parcel scenarios. The workflow focuses on roof segmentation, module placement, and engineering outputs like single-line diagrams and design documentation.

It also supports geometry-driven constraint checking such as setbacks and obstruction handling to keep layouts aligned with site conditions. ARKA 360’s value for teams is controlled configuration of layout rules and repeatable design generation across projects.

Scanifly targets solar layout teams that need quick roof-based modeling tied to engineering outputs like CAD export and downstream design packages. The workflow centers on generating PV layouts from site inputs, then refining placement with constraint-aware checks for spacing and layout rules.

Scanifly focuses on practical production needs like obstruction handling, plan generation, and file export for handoff. Integration depth and automation depend on what output formats and interfaces are available in the design-to-CAD and design-to-model pipeline.

Solargis Prospect focuses on geospatial-ready PV design workflows for teams that need parcel and terrain context before module placement. It supports roof and site mapping inputs used for obstruction and shading assessments, then connects those results to layout constraints like setback compliance and electrical sizing outputs.

The tool’s distinction is its emphasis on modeling inputs and exports that fit downstream design and permitting work rather than only drawing a single-line diagram. Grid-oriented iteration is handled through repeatable configuration runs that reduce manual rework when site geometry or assumptions change.

Fronius Solar.creator targets installer workflows around Fronius inverter projects, with layout, shading, and reporting centered on Fronius hardware output. The software builds roof segmentation and designs string wiring to produce documentation that can feed typical electrical and design handoff steps.

Shading and yield modeling help validate orientation choices and plan for module placement constraints. Export options support CAD and PV design workstreams, with Fronius-oriented project data that reduces rework when standardizing on the Fronius ecosystem.

Solar Monkey generates solar layout designs from a web-based workflow that focuses on roof segmentation, panel placement, and constraint checks in one pass. The core capability centers on producing CAD-ready deliverables for installer handoffs, plus reporting that ties layout decisions back to measurable geometry inputs.

Solar Monkey also supports geospatial inputs and obstruction handling so designs can be iterated without rebuilding models from scratch. Integration depth is practical through export and workflow automation hooks rather than a deep API-first design model.

K2 Base targets PV layout workflows where installers need consistent drawing output across many roof types and projects. It centers on roof segmentation, panel placement configuration, and generation of design artifacts that can be used for review and handoff.

The software’s distinct angle is its focus on repeatable project configuration that can be carried forward between sites with controlled settings. Where competitors differentiate through specific modeling engines, K2 Base differentiates through layout-driven execution and export interoperability for downstream work.
