TL;DR: No single solar platform does everything well. SurgePV ($1,899/year for 3 users) covers design, simulation, and proposals in one package. PVsyst remains the bankability gold standard for simulation. Aurora Solar leads in remote design automation. OpenSolar offers a free entry point. The right choice depends on whether you need bankable reports, fast proposals, or full-stack coverage. This guide compares all 10 tools across every category that matters.
Why a Side-by-Side Comparison Matters
Most “comparison” articles rank tools from best to worst. That’s not useful when the best tool for a 5 kW residential installer in Texas is different from the best tool for a 50 MW utility developer in Germany.
Solar software falls into three functional categories: design, simulation, and proposals. Some tools cover one category well. A few cover two. Very few handle all three without forcing you into workarounds or third-party integrations.
The problem is this: if your solar software only handles design, you still need separate tools for simulation and proposals. That means exporting files between platforms, re-entering project data, and reconciling inconsistent results. A 10-minute design becomes a 45-minute workflow spread across three apps.
This comparison evaluates 10 tools across all three categories. We tested each platform on residential and commercial projects, documented feature coverage, checked pricing against published rates, and verified simulation accuracy against IEC 61724 standards.
In this guide, you’ll find:
- A master comparison table covering all 10 platforms at a glance
- Feature matrices for design, simulation, and proposals
- Pricing breakdown with per-user and per-project costs
- A decision table matching each tool to specific installer profiles

Design Features Matrix
Design is where your workflow starts. The quality of your 3D model, shading analysis, and module placement directly affects simulation accuracy downstream.
Roof Design Capabilities
| Feature | SurgePV | Aurora Solar | PV*SOL | HelioScope | OpenSolar | Solargraf |
|---|---|---|---|---|---|---|
| LIDAR Roof Import | Yes | Yes | No | Yes | Yes | Yes |
| Manual Roof Drawing | Yes | Yes | Yes | Yes | Yes | Yes |
| Drone Imagery Import | Yes | Yes | No | Yes | No | No |
| Auto Module Placement | Yes | Yes | Yes | Yes | Yes | Yes |
| Setback Rules | Yes | Yes | Manual | Yes | Yes | Yes |
| Fire Code Compliance | Yes | Yes | Manual | Yes | Yes | Yes |
| Obstruction Drawing | Yes | Yes | Yes | Yes | Yes | Basic |
| Multi-Roof Arrays | Yes | Yes | Yes | Yes | Yes | Limited |
For residential installers, roof design accuracy depends on two things: the quality of the underlying roof model and the intelligence of the auto-placement algorithm.
Aurora Solar uses LIDAR data and HD aerial imagery combined with AI to generate 3D roof models automatically. Their SmartRoof technology handles complex roof geometries (dormers, hip-valley intersections, skylights) with minimal manual correction. For US residential, this is the fastest path from address to design.
SurgePV takes a similar approach with LIDAR integration but adds manual precision tools for cases where automated modeling falls short. Complex European roofs with irregular geometries, attached garages, and chimney placements often need manual adjustment that pure AI struggles with.
PV*SOL requires manual 3D modeling but provides the most detailed shading simulation. Every dormer, chimney, tree, and neighboring building is modeled as a 3D object with minute-by-minute shadow casting. The tradeoff: it takes 20-30 minutes to build a model that Aurora generates in 2 minutes.
Ground-Mount and Commercial Design
| Feature | SurgePV | PVcase | PV*SOL | HelioScope | Aurora Solar |
|---|---|---|---|---|---|
| Terrain Following | Yes | Yes | Yes | Yes | Limited |
| Tracker Layouts | Yes | Yes | No | Yes | No |
| Cable Routing | Yes | Yes | No | Limited | No |
| Inverter Pad Placement | Yes | Yes | No | Yes | No |
| Substation Design | No | Yes | No | No | No |
| Civil Grading | No | Yes | No | No | No |
| CAD Export (DXF/DWG) | Yes | Yes | Yes | Yes | Yes |
| Utility-Scale (10+ MW) | Yes | Yes | Limited | Yes | No |
PVcase dominates utility-scale design. It works as a plugin for AutoCAD and Civil 3D, which means engineers stay in their native CAD environment. Terrain-following tracker layouts, automatic cable routing, and civil grading integration make it the standard for projects above 10 MW.
HelioScope handles commercial rooftop and ground-mount projects well in a browser. No software installation. Upload a satellite image, draw your array boundaries, and HelioScope auto-fills with modules based on your setback and spacing rules. For commercial projects between 100 kW and 5 MW, it’s fast and accurate.
SurgePV bridges the gap between residential and commercial. The same platform handles a 5 kW residential roof and a 2 MW ground-mount without switching tools. Terrain-following, tracker layouts, and cable routing are built in, though utility-scale projects above 10 MW may benefit from PVcase’s deeper CAD integration.
Pro Tip
If you design both rooftop and ground-mount systems, choose a platform that handles both. Maintaining separate tools for residential and commercial doubles your training costs and fragments your project data. See our best solar design software comparison for the full breakdown.
Simulation Features Matrix
Simulation accuracy determines whether your production estimates hold up against real-world performance. For financed projects, bankable simulation is non-negotiable.
| Feature | SurgePV | Aurora Solar | PVsyst | PV*SOL | HelioScope | HOMER | SAM |
|---|---|---|---|---|---|---|---|
| Hourly Simulation | Yes | Yes | Yes | Yes | Yes | Yes | Yes |
| Sub-Hourly (15 min) | Yes | No | Yes | Yes | No | Yes | Yes |
| Meteo Database | Yes | Yes | Yes | Yes | Yes | Yes | Yes |
| P50/P90 Uncertainty | Yes | Yes | Yes | Yes | No | Yes | Yes |
| Bifacial Modeling | Yes | Yes | Yes | Yes | Yes | No | Yes |
| Battery Storage | Yes | Yes | Yes | Yes | No | Yes | Yes |
| Degradation Modeling | Yes | Yes | Yes | Yes | Yes | Yes | Yes |

| Mismatch Analysis | Yes | Limited | Yes | Yes | Yes | No | Yes |
| IEC 61724 Compliant | Yes | Yes | Yes | Yes | Partial | No | Yes |
Bankability and Lender Acceptance
This is where the field narrows. Lenders, independent engineers, and project finance institutions require simulation reports from tools they trust.
PVsyst is the global standard for bankable simulation. If a lender asks for a “PVsyst report,” they mean it literally. The software’s loss chain methodology, meteorological data handling, and uncertainty analysis are accepted by every major solar lender worldwide. For utility-scale and large commercial projects that require third-party financing, PVsyst is mandatory.
SurgePV produces P50/P90 reports with IEC 61724-compliant simulation methodology. For residential and mid-commercial projects where in-house financing or simpler lending structures apply, SurgePV’s simulation is sufficient. For utility-scale bankability, pair SurgePV’s design with PVsyst’s simulation engine.
Aurora Solar provides bankable reports accepted by major US residential lenders. Their simulation engine uses hourly irradiance data and component-level loss modeling. For US residential solar loans and leases, Aurora’s reports satisfy lender requirements.
SAM (System Advisor Model) from NREL is free and open-source. Researchers and developers use it for detailed financial modeling, technology comparisons, and policy analysis. It’s not a design tool, but its simulation engine is among the most comprehensive available. The learning curve is steep, and there’s no commercial support.
HOMER Energy specializes in hybrid systems — solar + wind + diesel + battery + grid. If you’re designing microgrids, off-grid systems, or hybrid energy solutions, HOMER’s optimization engine finds the least-cost combination of generation and storage. It’s not a PV design tool; it’s a system architecture optimizer.
Key Takeaway
For residential and small commercial: SurgePV or Aurora Solar simulation is sufficient. For utility-scale finance: PVsyst is required. For microgrids: HOMER Energy. For research: SAM. See our full best simulation software comparison.
Proposal Features Matrix
Proposals convert designs into sales. The speed from “design complete” to “proposal sent” determines how many deals your sales team closes per week.
| Feature | SurgePV | Aurora Solar | OpenSolar | Solargraf |
|---|---|---|---|---|
| Branded Templates | Yes | Yes | Yes | Yes |
| Dynamic Pricing | Yes | Yes | Yes | Yes |
| Multiple System Options | Yes | Yes | Yes | Yes |
| Financing Calculators | Yes | Yes | Yes | Yes |
| E-Signature | Yes | Yes | Yes | Yes |
| Online Proposal Portal | Yes | Yes | Yes | Yes |
| Loan/Lease/PPA Options | Yes | Yes | Yes | Limited |
| Utility Rate Modeling | Yes | Yes | Yes | Yes |
| Savings Projections | Yes | Yes | Yes | Yes |
| CRM Integration | Yes | Yes | Limited | Yes |
| Multi-Language | Yes | Limited | Limited | Limited |
Only four of the ten platforms include built-in proposal generation. PVsyst, PV*SOL, HelioScope, PVcase, HOMER, and SAM are engineering tools — they produce technical reports, not customer-facing proposals.
If your workflow requires proposals, your choices narrow to SurgePV, Aurora Solar, OpenSolar, or Solargraf. Each approaches proposals differently.
SurgePV generates proposals directly from the design and simulation data already in the platform. No export, no re-entry. The proposal includes 3D visualizations, production estimates, financial analysis, and e-signature. For installers who want one tool from design through contract signing, this eliminates the fragmentation of separate design and proposal apps.
Aurora Solar offers a similar integrated experience with strong sales automation features. Their Sales Mode lets sales reps modify designs in real-time during customer meetings without touching the engineering backend. For high-volume residential operations with separate sales and engineering teams, this workflow separation is valuable.
OpenSolar is free and includes financing marketplace integration. Installers can present loan and lease options from multiple lenders directly within the proposal. For small installers who need proposals without a software subscription, OpenSolar is the zero-cost entry point.
Solargraf (by Enphase) focuses on speed. Upload a utility bill, select equipment, and generate a proposal in minutes. The simulation depth is limited compared to SurgePV or Aurora, but for residential installers selling standardized packages, speed matters more than simulation precision.
Pro Tip
Proposal speed directly affects close rates. Installers who send proposals within 24 hours of the site visit close 30-40% more deals than those who take 3-5 days. Choose a platform where design-to-proposal takes minutes, not days. See our best proposal software comparison.
Pricing Comparison
Pricing structures vary across subscription models, per-project fees, perpetual licenses, and free tiers. This table reflects published pricing as of March 2026.
| Platform | Pricing Model | Starting Price | Per-User Cost | Free Tier |
|---|---|---|---|---|
| SurgePV | Annual subscription | $1,899/year (3 users) | ~$633/user/year | Demo available |
| Aurora Solar | Annual subscription | ~$3,600/year (est.) | Varies by plan | No |
| PVsyst | Perpetual + maintenance | ~$1,350 perpetual | Single-user license | 30-day trial |
| PV*SOL | Perpetual + maintenance | ~$1,200 perpetual | Single-user license | Free (PV*SOL basic) |
| HelioScope | Annual subscription | ~$2,388/year | ~$199/month | 14-day trial |
| OpenSolar | Free | $0 | $0 | Yes (full platform) |
| PVcase | Annual subscription | Custom pricing | Custom | 14-day trial |
| Solargraf | Annual subscription | Custom pricing | Custom | Limited free tier |
| HOMER Energy | Annual subscription | ~$1,188/year | Single-user license | Free (HOMER Front) |
| SAM (NREL) | Free | $0 | $0 | Yes (open-source) |
Cost Per Project Analysis
Raw subscription cost doesn’t tell the full story. What matters is cost per project completed.
An installer completing 200 residential projects per year:
| Platform | Annual Cost | Cost Per Project | Notes |
|---|---|---|---|
| SurgePV | $1,899 | $9.50 | Design + simulation + proposals included |
| Aurora Solar | ~$3,600 | ~$18.00 | Design + simulation + proposals included |
| PVsyst + Solargraf | ~$2,500 combined | ~$12.50 | Separate simulation + proposal tools |
| HelioScope + Solargraf | ~$3,600 combined | ~$18.00 | Separate design + proposal tools |
| OpenSolar | $0 | $0 | Free, but limited simulation depth |
The cost calculation shifts for commercial projects. An EPC completing 20 commercial projects per year:
| Platform | Annual Cost | Cost Per Project | Notes |
|---|---|---|---|
| SurgePV | $1,899 | $94.95 | Handles commercial design + simulation |
| PVsyst | ~$1,350 (one-time) | ~$67.50 (Year 1) | Bankable simulation, no design |
| HelioScope | ~$2,388 | $119.40 | Commercial design, limited proposals |
| PVcase | Custom (~$5,000+) | ~$250+ | Utility-scale, CAD-native |
Key Takeaway
For residential volume, SurgePV offers the lowest cost per project among paid all-in-one platforms. OpenSolar is free but trades simulation depth for price. For utility-scale, PVsyst’s perpetual license becomes cost-effective after Year 1.
All-in-One vs. Best-of-Breed
The fundamental decision: do you want one platform that does everything, or do you assemble the best tool for each category?
All-in-One Platforms
| Platform | Design | Simulation | Proposals | Tradeoff |
|---|---|---|---|---|
| SurgePV | Strong | Strong | Strong | No utility-scale CAD integration |
| Aurora Solar | Strong | Strong | Strong | Higher price, US-centric |
| OpenSolar | Adequate | Basic | Strong | Limited simulation accuracy for complex projects |
When all-in-one works: residential installers, small commercial EPCs, and companies where speed and simplicity matter more than simulation precision for bankable reports.
When all-in-one falls short: utility-scale projects requiring PVsyst bankability, complex ground-mount designs needing CAD-native tools, or microgrid projects requiring HOMER’s optimization.
Best-of-Breed Stack
Common professional stacks:
| Stack | Design | Simulation | Proposals | Total Cost |
|---|---|---|---|---|
| PVsyst + AutoCAD + Custom | Manual/CAD | PVsyst | Custom PDF | ~$3,000+/year |
| HelioScope + PVsyst + Solargraf | HelioScope | PVsyst | Solargraf | ~$4,500+/year |
| PVcase + PVsyst | PVcase (CAD) | PVsyst | Manual | ~$6,000+/year |
| SurgePV standalone | SurgePV | SurgePV | SurgePV | $1,899/year |
The best-of-breed approach costs more, requires data export between tools, and creates version control challenges. But it gives you the strongest tool in each category.
For most residential and commercial installers, the all-in-one approach saves time and money. For utility-scale developers and specialized EPCs, best-of-breed is worth the overhead. See our best all-in-one solar software comparison for a deeper dive.

Which Tool Is Right for You?
High-Volume Residential Installer (200+ Projects/Year)
You need speed. Address to proposal in under 30 minutes. Financing integration so customers can see loan payments on screen. E-signatures so contracts close on the spot.
Best choice: SurgePV or Aurora Solar. Both handle the full residential workflow. SurgePV is more affordable ($1,899 vs. ~$3,600/year). Aurora offers stronger AI-powered roof detection for US addresses.
Budget alternative: OpenSolar. Free, with integrated financing. Simulation depth is limited, but for standardized residential packages, it gets the job done.
Commercial and Industrial EPC (20-50 Projects/Year)
You need accurate simulation for projects where production guarantees carry financial penalties. Design flexibility for flat roofs, carports, and ground-mount arrays. Technical reports that satisfy engineering review.
Best choice: SurgePV for design + simulation, paired with PVsyst if lenders require PVsyst-specific reports. HelioScope is a strong alternative for browser-based commercial design.
Utility-Scale Developer (1-10 Projects/Year)
You need CAD-native design tools, bankable simulation, and the ability to model terrain, trackers, cable routing, and civil grading. Cost per project is less important than accuracy and lender acceptance.
Best choice: PVcase for design + PVsyst for simulation. This is the industry-standard utility-scale stack. Accept the combined cost as a project expense.
Solar Sales Organization (Proposals Only)
You don’t design systems. Your engineering team handles that. You need fast, branded proposals with financing options and e-signatures.
Best choice: Solargraf for Enphase-based residential, or Aurora Solar Sales Mode for high-volume operations with separate sales and engineering teams.
Researcher or Policy Analyst
You need detailed simulation with full parameter control, technology comparison capabilities, and financial modeling for policy analysis. Commercial support is less important than methodological transparency.
Best choice: SAM (NREL). Free, open-source, and backed by the US Department of Energy. The learning curve is steep, but the simulation depth is unmatched for research purposes.
Off-Grid and Microgrid Designer
You’re designing hybrid systems with solar, wind, diesel generators, and battery storage. Least-cost optimization across multiple generation sources is the core requirement.
Best choice: HOMER Energy. It’s the standard for microgrid optimization. Pair it with SurgePV or PVsyst for the solar-specific design and simulation, then use HOMER for system architecture optimization.
Regional Considerations
Europe
European installers face specific requirements: country-specific subsidy calculations, VAT handling, local meteorological databases, and compliance with regional building codes. Multi-language support matters when operating across borders.
SurgePV and PV*SOL handle European markets well. PV*SOL’s German engineering heritage means strong compliance with DIN standards and detailed shadow analysis capabilities. SurgePV supports multiple European countries with localized weather data and regulatory compliance.
PVsyst is used globally but originated in Switzerland. Its meteorological database includes comprehensive European coverage, and its loss modeling accounts for European-specific factors like snow loading patterns.
North America
US installers benefit from strong LIDAR coverage (most urban areas have high-resolution roof data), standardized utility rate databases, and integrated loan/lease marketplace access.
Aurora Solar has the strongest US-specific feature set: AI roof detection trained on US housing stock, utility rate database integration, and financing marketplace partnerships with major US lenders. SurgePV offers comparable US coverage with broader international support.
Asia-Pacific and Emerging Markets
For markets with limited LIDAR coverage, manual design tools become more important. Satellite imagery-based design and offline simulation capability matter in areas with unreliable internet.
PVsyst works offline and supports any location with meteorological data. PV*SOL is also desktop-based. Browser-dependent tools like HelioScope and Aurora require stable internet connections that may not be available at remote project sites.
Platform Comparison by Update Frequency
Software that doesn’t update frequently falls behind on equipment databases, regulatory changes, and performance improvements.
| Platform | Update Cycle | Equipment Database Updates | Last Major Release |
|---|---|---|---|
| SurgePV | Monthly | Monthly | March 2026 |
| Aurora Solar | Bi-weekly | Monthly | March 2026 |
| PVsyst | Quarterly | Quarterly | Q1 2026 |
| PV*SOL | Semi-annual | Quarterly | Q4 2025 |
| HelioScope | Monthly | Monthly | February 2026 |
| OpenSolar | Monthly | Monthly | February 2026 |
| PVcase | Monthly | Monthly | March 2026 |
| Solargraf | Monthly | Monthly | March 2026 |
| HOMER Energy | Quarterly | Quarterly | Q4 2025 |
| SAM (NREL) | Annual | Annual | 2025.12.17 |
Cloud-based platforms (SurgePV, Aurora, HelioScope, OpenSolar) update more frequently because updates deploy automatically. Desktop software (PVsyst, PV*SOL, SAM) requires manual installation and tends to update less often.
The Bottom Line
There is no single best solar software platform. There is the best platform for your specific workflow, project types, and budget.
For residential installers who want one tool from design to contract: SurgePV at $1,899/year delivers the best value. Aurora Solar offers stronger AI automation at a higher price. OpenSolar is free if budget is the primary constraint.
For commercial EPCs: SurgePV or HelioScope for design, paired with PVsyst when bankable simulation is required.
For utility-scale developers: PVcase for design, PVsyst for simulation. No substitutes.
For researchers: SAM is free and comprehensive. For microgrids: HOMER Energy is the standard.
Start with the decision table above. Match your project volume, project type, and budget to the recommended stack. Then test with a free trial before committing to an annual subscription.

Frequently Asked Questions
What is the best solar software overall in 2026?
There is no single best solar software for every use case. For residential installers who need design, simulation, and proposals in one platform, SurgePV offers the best value at $1,899/year for 3 users. For AI-powered remote design in the US market, Aurora Solar leads. For bankable simulation accepted by all lenders, PVsyst remains the industry standard. For free access with integrated financing, OpenSolar is the best zero-cost option.
How do I choose between all-in-one and best-of-breed solar software?
All-in-one platforms (SurgePV, Aurora Solar, OpenSolar) handle design, simulation, and proposals in a single tool. This reduces data re-entry, eliminates export errors, and speeds up the workflow. Best-of-breed stacks (PVcase + PVsyst, for example) give you the strongest tool in each category but cost more and require data transfer between platforms. Choose all-in-one for residential and small commercial. Choose best-of-breed for utility-scale projects where bankability and CAD-native design are non-negotiable.
Is PVsyst still required for bankable solar simulation?
For utility-scale and large commercial projects that require third-party financing, PVsyst remains the default requirement. Lenders, independent engineers, and project finance institutions specifically request PVsyst reports. For residential solar loans and smaller commercial projects, simulation reports from SurgePV or Aurora Solar are generally accepted. The bankability requirement depends on your lender, not on the software itself.
What is the cheapest solar software for small installers?
OpenSolar is completely free and includes design, simulation, and proposal tools. SAM (NREL) is free for simulation and financial modeling. PV*SOL offers a free basic version for simple residential projects. Among paid platforms, SurgePV at $1,899/year for 3 users offers the lowest per-user cost for a full-featured all-in-one platform, working out to roughly $633 per user per year.
Can I use multiple solar software tools together?
Yes. Many professional workflows combine tools. A common stack is PVcase for utility-scale CAD design, PVsyst for bankable simulation, and a separate proposal tool for customer-facing documents. The tradeoff is data transfer overhead: you export from one tool and import into another, which adds time and introduces version control challenges. All-in-one platforms like SurgePV eliminate this overhead by keeping design, simulation, and proposals in a single environment.
