SketchUp for Solar Review: Features, Pricing & Pros vs Cons (2026)

TL;DR: SketchUp for solar design is Trimble’s 3D modeling platform used with the Skelion plugin for solar layout and shadow analysis. At $349/year for SketchUp Pro plus Skelion Pro, it delivers the best 3D visualization in the industry — but it is not standalone solar software. A complete commercial workflow requires PVsyst ($647/year) and AutoCAD ($2,000+/year), pushing total stack cost past $3,000/year. For 3D visualization and client presentations, SketchUp is genuinely excellent. For teams needing design-to-proposal in one tool, SurgePV — the leading solar design software — covers the full workflow from layout to SLD to proposal without additional tools.

Who This Review Is For

This SketchUp for solar review is written for:

• Solar designers evaluating SketchUp and Skelion for project visualization
• Commercial EPCs deciding whether to add SketchUp to an existing design stack
• Architects and engineers with existing SketchUp skills looking to add solar work
• Teams comparing SketchUp vs dedicated solar platforms for overall workflow cost

Who should skip this review:

• Teams needing an all-in-one solar platform (SketchUp is not one)
• Residential installers who want design, proposal, and electrical in a single subscription
• High-volume commercial EPCs where per-project time savings matter most

What Is SketchUp for Solar?

SketchUp is a 3D modeling platform developed by Trimble (acquired from Google in 2012, originally launched in 2000). It is not solar software. It is a general-purpose 3D modeling tool used across architecture, construction, and engineering — and heavily adopted in the solar industry via a plugin ecosystem, primarily through Skelion.

The SketchUp-for-solar workflow works like this: SketchUp provides the 3D modeling engine and shadow visualization. The Skelion plugin adds solar-specific tools — panel placement, energy reports, PVsyst export. For bankable simulations, the 3D model exports to PVsyst. For electrical documentation, AutoCAD handles the SLD generation.

This means SketchUp is always one component in a multi-tool stack, not a standalone platform.

Company Background

How SketchUp Fits in a Solar Workflow

SketchUp sits in the preliminary design and visualization layer of the solar workflow:

1. Site modeling — Build or import 3D site geometry in SketchUp
2. Panel layout — Use Skelion to place panels automatically on any surface
3. Shadow analysis — Use SketchUp’s real-time shadow engine for visual analysis
4. Energy estimate — Run PVWatts or PVGis reports via Skelion
5. Detailed simulation — Export 3D model to PVsyst for bankable calculations
6. Electrical drawings — Move to AutoCAD for SLD and permit packages
7. Proposal — Use a separate proposal tool

This is the workflow used by large EPCs like Kirloskar Solar, which documented 98% accuracy in solar site studies using SketchUp.

SketchUp Pricing Plans 2026

SketchUp uses a subscription model. Plugin costs like Skelion are separate.

SketchUp License Price 2026

Most solar professionals use SketchUp Pro at $349/year. This is the plan that supports third-party extensions like Skelion.

Skelion Plugin Pricing

Skelion Pro pricing is not published on their website. Contact skelion.com for current rates.

Full Stack Cost for Commercial Solar Work

This is the number most pricing comparisons miss. SketchUp Pro alone does not deliver a complete commercial solar workflow.

Total Cost of Ownership Comparison

Is SketchUp Free? Free Trial Options

SketchUp Free exists but is heavily limited. It is web-only, cannot run desktop extensions, and therefore cannot run Skelion. You cannot do real solar design work with the free plan.

For a proper evaluation:

• SketchUp offers a 30-day free trial of Pro and Studio plans
• Skelion Free is permanently free but limited to 10 panels

If you want to test the SketchUp + Skelion workflow before purchasing, use the SketchUp Pro trial with Skelion Free on a small residential project (10 panels or fewer to stay within Skelion’s free limit).

Core Features & Capabilities

3D Modeling and Site Design

SketchUp’s core value in solar work is 3D geometry modeling. It is genuinely the best tool in the category for this specific job. The modeling engine handles complex roof geometries, irregular surfaces, and multi-structure commercial sites with a level of visual fidelity that dedicated solar tools do not match.

Key modeling capabilities:

• Intuitive push/pull geometry modeling — no CAD expertise required
• Real-time shadow engine based on geographic location and time of year
• Geolocation via Google Earth for accurate site positioning
• 3D Warehouse library of pre-built structures, equipment, and components
• Offline capability on desktop plans (Pro, Studio) — work on-site without internet

The real-time shadow engine is particularly useful for solar assessments. Designers can scrub through any date and time and see exactly how shading falls across the array, which is more intuitive than numerical shading reports for client presentations.

Skelion: The Solar Plugin for SketchUp

Skelion is what turns SketchUp into a solar design tool. Without it, SketchUp has no solar-specific functionality beyond shadow visualization.

What Skelion Pro adds:

• Automatic panel insertion on any SketchUp surface (1-click to 4-click workflows)
• Tilt and azimuth calculation for any orientation
• PV module database (expandable with custom models)
• Shading angle control for any hour of the year
• Energy production reports via PVWatts (US) and PVGis (EU)
• PVsyst export capability for bankable simulation
• Ground-mounted and rooftop system design
• Residential and commercial scale support

The speed improvement from Skelion is documented. A professional user review from LinkedIn describes the workflow shift: “Users can do with four clicks what they were doing in four hours. Skelion reduced considerably average time on layouts and energy production reports.”

Shadow Analysis Accuracy

SketchUp’s shadow analysis, validated by Kirloskar Solar, achieves 98% accuracy in site studies and daylight evaluations. This is based on a documented case study of one of India’s major solar EPC companies.

For shading accuracy context:

SketchUp’s 98% figure applies to site studies — shadow visibility and shading pattern accuracy. For bankable energy production numbers, PVsyst export is still recommended.

What SketchUp Cannot Do

These are hard limitations, not gaps that can be filled with settings or workarounds:

• No single-line diagram (SLD) generation
• No wire sizing calculation
• No conduit fill or voltage drop analysis
• No bill-of-materials (BOM) generation
• No automated solar proposal creation
• No financial modeling or ROI calculation
• No permit package generation
• No battery storage modeling
• No automated panel optimization (Skelion places panels, optimization is manual)

For commercial EPCs, the SLD gap is the most significant. Permit-ready electrical drawings require AutoCAD or a dedicated electrical tool, adding cost and time to every project.

Other Solar Plugins Worth Knowing

None of these replace Skelion for professional solar design.

Skelion Plugin Review: Deep Dive

Skelion is the reason most solar professionals use SketchUp at all. It deserves its own section given that two of the top GSC keywords for this review specifically target Skelion.

Skelion Free vs Skelion Pro

The free tier is a demonstration, not a working tool. Skelion Pro is required for any real project.

Skelion Pro Features in Practice

Panel placement speed is the headline feature. Skelion can place panels on a complex multi-faceted roof surface automatically, handling orientation, setbacks, and obstructions. The result is a layout that would take hours of manual CAD work produced in minutes.

Energy reports use PVWatts (US) or PVGis (EU) as the calculation engine. These are not as detailed as a full PVsyst simulation, but they are sufficient for preliminary feasibility work and client estimates.

PVsyst export is how serious engineers use SketchUp. After the visual layout is done in SketchUp + Skelion, the 3D model exports to PVsyst where detailed irradiance, shading, and production calculations run. This is the workflow Kirloskar Solar and other large EPCs follow.

Skelion Limitations

• Plugin beta status — users report occasional bugs requiring updates
• Third-party dependency means Skelion must keep pace with SketchUp version updates
• Solar North extension does not persist across scenes (known issue in community forums)
• Google Maps location accuracy issues have been reported
• No animation feature for shading losses over time

SketchUp Solar Features: Full Assessment

What SketchUp Does Best in Solar

1. Complex 3D site modeling SketchUp handles irregular geometries, multi-structure sites, and complex rooflines better than any dedicated solar tool. This matters for commercial projects with complicated site layouts.

2. Client visualization and presentations The visual output from SketchUp is architecture-grade. 3D renderings, shadow animations, and model walkthroughs are tools that close sales. Dedicated solar platforms produce functional visuals; SketchUp produces impressive ones.

3. Integration as a pre-simulation tool SketchUp fits naturally as the front end of a PVsyst workflow. The 3D model provides exact shading geometry, which PVsyst uses for its detailed optical calculations.

4. Flexibility for non-standard projects Carports, facades, atriums, pergolas, unusual tilt angles — SketchUp can model anything because it is a general 3D modeling tool, not constrained by solar-specific templates.

Where SketchUp Falls Short for Solar

1. No electrical outputs Commercial solar permits require SLDs, wire sizing calculations, and conduit fill documentation. SketchUp produces none of these. AutoCAD or a dedicated electrical tool handles this work separately.

2. No financial modeling Clients want payback periods, IRR, cash flow projections. SketchUp does not calculate any of this. A separate financial tool or generation and financial tool is required.

3. Tool-switching friction The SketchUp workflow requires moving between platforms: model in SketchUp, simulate in PVsyst, document in AutoCAD, propose in a proposal tool. Each handoff creates friction, potential errors, and additional learning curves.

4. Plugin reliability Third-party plugins occasionally break after SketchUp version updates. The Skelion + SketchUp combination has known compatibility lag periods where users must wait for Skelion to update before upgrading SketchUp.

User Reviews & Feedback

Detailed G2 review data for SketchUp as a solar-specific platform is limited (SketchUp reviews on G2 cover all industries, not solar specifically). The feedback below combines professional solar user reviews from LinkedIn, SketchUcation forums, and documented case studies.

Top Praised Features

Top Criticisms

Representative User Quote

“Skelion reduced considerably average time on layouts and energy production reports. Users can do with four clicks what they were doing in four hours.” — Professional solar designer (LinkedIn review)

The flip side from the same review: location accuracy with Google Maps was flagged as an issue, and the absence of financial analysis tools means SketchUp alone cannot produce a complete client deliverable.

Pros & Cons

Pros

1. Best 3D Visualization in Solar

No dedicated solar platform matches SketchUp for visual quality. Architecture-grade 3D renders, shadow animations, and model walkthroughs. If closing sales with impressive visuals matters to your team, SketchUp delivers this better than Aurora, SurgePV, or HelioScope.

2. Skelion Speed Transformation

“4 clicks vs 4 hours” is a real benchmark from professional users. Skelion’s automatic panel placement on complex surfaces dramatically reduces layout time compared to manual CAD-based workflows.

3. 98% Shadow Analysis Accuracy

Validated by Kirloskar Solar in documented site studies. For preliminary shadow assessments, this is sufficient for most residential and commercial projects before handing off to PVsyst.

4. Offline Capability

SketchUp Pro and Studio work without internet. For site visits, remote locations, or teams in areas with unreliable connectivity, this is a practical advantage over cloud-only platforms.

5. PVsyst Integration

The direct export from Skelion to PVsyst is clean and widely used. It positions SketchUp as the visualization front end to PVsyst’s calculation engine — a pairing that large EPCs like Kirloskar Solar use in production.

6. Flexible for Non-Standard Geometries

Facades, carports, canopies, irregular rooflines — SketchUp models anything. Dedicated solar platforms constrain design to standard templates; SketchUp does not.

Cons

1. Not Standalone Solar Software

SketchUp requires Skelion for solar-specific work. Skelion requires PVsyst for bankable simulations. PVsyst workflows often require AutoCAD for electrical documentation. The full commercial stack costs over $3,000/year.

2. No Electrical Engineering

Single-line diagrams, wire sizing, conduit fill — none of these exist in SketchUp. Commercial permit packages need AutoCAD or a dedicated electrical tool. At scale, this adds 2–3 hours per project in manual work.

3. No Financial Modeling

No ROI, payback period, IRR, or cash flow analysis. No bill of materials. Clients making purchasing decisions need this data, which means a separate tool is required for every project that needs financial justification.

4. No Automated Proposals

SketchUp cannot produce a client-ready solar proposal. After completing the 3D model, designers must move to a separate proposal tool — adding another subscription and another workflow step.

5. Free Tier Is Non-Functional for Solar

Skelion Free limits users to 10 panels. SketchUp Free is web-only with no extension support. Neither is viable for real solar work. The “entry-level pricing” headline is misleading for solar professionals.

6. Plugin Dependency Risk

When SketchUp releases updates, Skelion compatibility sometimes lags. Users have reported periods where upgrading SketchUp breaks Skelion, forcing a choice between staying on an older SketchUp version or losing solar functionality temporarily.

SketchUp vs SurgePV

SketchUp and SurgePV address different parts of the solar workflow. This comparison covers the key decision points for solar EPCs and installers.

Feature Comparison

Workflow Time: 100 kW Commercial Project

Annual Cost Comparison

The calculation shifts at commercial scale. SketchUp’s low base price is real, but teams doing 30+ commercial projects per month spend 6–9 additional hours per project assembling outputs from multiple tools. At $75/hour, that’s $450–675 per project in labor — more than the software cost differential.

SketchUp for Solar Alternatives

If SketchUp does not fit your workflow, here are the main alternatives by use case.

Aurora Solar is the most direct alternative for residential and commercial solar design with proposal generation. It includes automated roof modeling from aerial imagery, shading analysis, financial modeling, and proposal tools in one platform. Aurora does not match SketchUp’s 3D visualization quality, but it produces complete client deliverables without additional software.

SurgePV covers the full commercial solar workflow — 3D design, shading analysis, automated SLD generation, financial modeling, and proposals — in a single platform. For EPCs that currently use SketchUp + AutoCAD + a proposal tool, SurgePV consolidates the stack. Solar design software that handles electrical engineering is the key differentiator at commercial scale.

HelioScope is a cloud-based simulation and design platform used for commercial and utility-scale work. It integrates with SketchUp in some workflows (SketchUp for 3D modeling, HelioScope for simulation). As a standalone tool, HelioScope has stronger simulation depth than SketchUp + Skelion but lacks the visualization quality.

PVsyst is the bankable simulation standard, not a layout tool. It works best downstream of SketchUp — SketchUp + Skelion creates the 3D model, PVsyst runs the detailed calculations. As an alternative to SketchUp, PVsyst does not replace the visualization and layout functions.

OpenSolar is a free all-in-one platform for residential and light commercial solar. It handles design, shading, proposals, and some financial modeling without the multi-tool complexity of a SketchUp stack. The trade-off is significantly less 3D visualization depth.

AutoCAD is commonly used alongside SketchUp for electrical documentation. Some teams build their entire solar workflow in AutoCAD without SketchUp. AutoCAD is stronger for electrical drawings; SketchUp is stronger for 3D visualization. They often coexist in the same workflow.

Who Should Use SketchUp for Solar?

SketchUp Is a Good Fit When:

You already know SketchUp. If your team has architects or engineers who use SketchUp for other work, adding solar via Skelion is a natural extension. The learning investment is largely already made.

3D visualization is your primary deliverable. For firms selling to clients who respond to visual presentations — architects, landscape architects, premium residential installers — SketchUp’s rendering quality is a competitive advantage.

You export to PVsyst anyway. Large EPCs doing bankable work typically run PVsyst regardless of what front-end design tool they use. If PVsyst is already in your stack, SketchUp’s export integration makes sense.

You work on non-standard geometries. Facades, carports, pergolas, irregular rooflines, complex multi-structure sites — SketchUp handles these more flexibly than any template-based solar platform.

Offline capability matters. Site visits, remote installations, locations with unreliable internet — SketchUp Pro and Studio work without a connection.

SketchUp Is the Wrong Choice When:

You need an all-in-one workflow. SketchUp requires multiple additional tools to produce complete project deliverables. If reducing tool-switching is a priority, a dedicated solar software platform is a better fit.

Electrical documentation is on your plate. Commercial permits require SLDs and wire sizing. SketchUp cannot produce these. If you are responsible for permit-ready electrical drawings, budget for AutoCAD on top of SketchUp.

You need automated proposals. SketchUp produces no proposals. If client proposals are a core deliverable, a separate proposal tool is required.

High volume, short timelines. The multi-tool workflow works at low volume. At 30+ commercial projects per month, the time spent moving data between SketchUp, PVsyst, AutoCAD, and a proposal tool becomes a material cost.

Frequently Asked Questions

What is SketchUp for solar?

SketchUp for solar refers to the use of Trimble’s SketchUp 3D modeling platform — combined with the Skelion plugin — to design, visualize, and analyze solar PV systems. SketchUp handles 3D geometry and shadow visualization. Skelion adds panel placement, energy reporting, and PVsyst export. It is not standalone solar software; it functions as one part of a multi-tool design workflow.

What are SketchUp pricing plans in 2026?

SketchUp offers four plans: Free (web-only, no solar plugins), Go at $149/year, Pro at $349/year (industry standard for solar professionals), and Studio at $779/year. Skelion Pro pricing is separate and not publicly disclosed. A complete commercial solar stack (SketchUp + Skelion + PVsyst + AutoCAD) costs over $3,000/year. See the pricing section above for the full breakdown.

What is Skelion?

Skelion is the primary solar plugin for SketchUp, developed as a third-party extension. It adds automatic panel insertion on any 3D surface, tilt and azimuth calculation, PV module database access, energy production reports via PVWatts and PVGis, and PVsyst export. Skelion Free is limited to 10 panels. Skelion Pro is required for professional solar work.

Is Skelion Pro worth it?

Yes, if you use SketchUp for solar design. The free version’s 10-panel limit makes it non-functional for real projects. Skelion Pro enables the “4 clicks vs 4 hours” speed improvement documented by professional users, plus PVsyst export and energy reports. Without Skelion Pro, SketchUp is just a 3D modeling tool with no solar-specific features.

Can SketchUp generate SLDs or electrical drawings?

No. SketchUp cannot generate single-line diagrams, wire sizing calculations, conduit fill documentation, or any other electrical engineering outputs. Commercial permit packages require AutoCAD or a dedicated electrical tool in addition to SketchUp. SurgePV generates automated SLDs in 5–10 minutes with no additional software.

Is SketchUp for solar free?

SketchUp Free exists but is web-only and cannot run the Skelion plugin, making it non-functional for real solar design work. SketchUp Pro ($349/year) is required for solar use. The free tier of Skelion limits panel count to 10. A proper solar workflow requires paid versions of both SketchUp and Skelion, plus typically PVsyst and AutoCAD.

What is the best SketchUp solar plugin?

Skelion is the best and most widely used solar plugin for SketchUp. It provides automatic panel placement, a comprehensive PV module database, energy reports, and PVsyst export. Other plugins (SunHours, su_solarnorth, Solar Panel Modeller) serve specific niche functions but do not replace Skelion for full solar project work.

Final Verdict

SketchUp for Solar: Strengths and Limitations

Strengths:

• Best 3D visualization quality in the solar industry — architecture-grade client presentations
• Skelion delivers genuine speed improvement (4 clicks vs 4 hours for panel layout)
• 98% shadow analysis accuracy validated in production by Kirloskar Solar
• Offline capability for site visits and remote work
• Flexible enough to handle any geometry — facades, carports, irregular rooflines
• Natural pairing with PVsyst for bankable simulation workflows

Limitations:

• Not standalone solar software — requires Skelion, PVsyst, and AutoCAD for complete work
• No SLD generation, no wire sizing, no proposals, no financial modeling
• Full commercial stack costs over $3,000/year
• Plugin dependency creates update compatibility risk
• Multi-tool workflow adds 5–8 hours per commercial project compared to integrated platforms

The Decision Framework

Choose SketchUp for solar when:

• Your team already uses SketchUp for architecture or construction
• 3D visualization quality is a sales differentiator for your clients
• PVsyst is already in your workflow and you need a front-end visualization tool
• You design non-standard geometries (facades, carports, irregular sites)
• Offline capability is a practical requirement

Choose SurgePV when:

• You need design, simulation, SLD, financial modeling, and proposals in one platform
• Commercial electrical documentation is part of your deliverable
• You do 10+ commercial projects per month and multi-tool switching adds up
• Your team does not have existing SketchUp expertise to leverage
• All-in cost matters: SurgePV at $1,499/user beats a full SketchUp commercial stack

Value Assessment

SketchUp makes economic sense in three scenarios: you already own it, you need its specific 3D visualization quality, or you have an existing PVsyst workflow and need a better front-end. In these cases, the incremental cost of adding Skelion Pro is justified.

For teams without existing SketchUp expertise, building a new workflow around SketchUp means learning SketchUp, Skelion, PVsyst, and AutoCAD — four separate tools, four separate learning curves, over $3,000/year in combined cost. A purpose-built solar design software platform covers the same workflow in a single subscription.

Take the Next Step

SketchUp is the right tool for visualization-first workflows. For teams that need a complete solar workflow — design to SLD to proposal — SurgePV covers every step without additional software.
