Document & Drawing Integration
Attach single-line diagrams, site plans, and permitting docs directly into the proposal package. One file, everything included.
Financial Modeling That Closes Deals
Commercial buyers need more than a payback estimate. Show them IRR, NPV, cash flows, and sensitivity analysis — all auto-generated from your solar design.
Advanced Financial Metrics
ROI, IRR, NPV, LCOE, and detailed cash flow projections. Built for the analysis that CFOs and investors actually review.
Tiered Financing Options
Model power purchase agreements, leases, loans, and cash purchases side by side. Let clients compare scenarios in one view.
Sensitivity & Risk Analysis
Show how changes in energy escalation, degradation, or incentive timelines affect returns. Build trust with transparent risk modeling.
Bankable Energy Reports & 3D Visuals
Lenders and independent engineers need confidence in your numbers. SurgePV delivers validated yield reports and professional visuals that hold up under scrutiny.
IEC-Compliant Yield Reports

Commercial Installers
Move from site visit to signed contract in one day. Present 3D designs, financing options, and savings projections on-site — no follow-up required.
Project Financiers & Investors
Review standardized proposals with consistent financial metrics across your portfolio. Compare projects side by side with uniform IRR, NPV, and LCOE reporting.
How to Choose Commercial Solar Proposal Software
Not every tool handles commercial scale. Here is what to evaluate before committing your team and your pipeline.
Check Project Size Limits
Many tools cap projects at 500 kW or charge exponentially above a threshold. SurgePV has no project size limit — model a 5 kW residential system or a 100 MW utility plant in the same workspace.
Verify Financial Model Depth
Residential tools often stop at simple payback. Commercial deals need IRR, NPV, LCOE, and cash flow analysis. Confirm the tool generates the metrics your investors and lenders require.
Evaluate Design Integration
If your proposal tool is separate from your design tool, you are re-entering data and risking errors. Solar design software with built-in proposals eliminates the handoff gap.
Test Output Flexibility
Commercial proposals serve multiple audiences. Can you generate an executive summary for the CFO, a technical brief for the engineer, and a full financial model for the investor — all from one project?
Review Pricing at Scale
Some platforms charge per project, per MW, or per user. SurgePV uses flat per-user annual pricing. Model as many projects as you want without watching your software costs eat into margins.
Commercial Solar Proposal Software 2026: Side-by-Side Comparison
Commercial EPCs and developers need more than polished PDFs. Here is how the major tools compare on the capabilities that matter for multi-MW deals.
| Tool | Project Size Limit | BOM Auto-Gen | Financial Modeling | Bankable Yield | White-Label | Pricing |
|---|---|---|---|---|---|---|
| SurgePV | ✓ Unlimited | ✓ Auto from design | ✓ ROI, IRR, NPV, LCOE | ✓ IEC-compliant | ✓ Full white-label | From $1,499/user/yr |
| Aurora Solar | Soft cap at 5 MW | ✓ Yes | Partial (US financing) | LIDAR-based | ✓ Polished PDFs | $2,640–$6,000+/user/yr |
| OpenSolar | ✗ 500 kW cap | Basic | Basic payback only | Simplified | Partial | Free (500 kW cap) |
| HelioScope | ✓ No hard cap | ✗ No | Basic energy yield | Design-focused | ✗ No proposals | $159–$259/month |
For Commercial EPCs
SurgePV is the only tool that combines bankable energy yield, auto-generated BOM, and branded proposals in one workflow. Aurora is strong for US residential but costly at scale. HelioScope has no proposals. OpenSolar caps at 500 kW.
For Project Developers
Developers need investor-grade financials and consistent reporting. SurgePV delivers IRR, NPV, and LCOE with standardized outputs. Aurora's financial modeling is US-market focused. HelioScope requires export to a separate tool for proposals.
For Budget-Conscious Teams
OpenSolar is free but the 500 kW cap rules out most commercial work. HelioScope is affordable but lacks proposal generation. SurgePV at $1,499/user/year replaces multiple tools and eliminates re-entry labor.
Why EPCs Choose SurgePV
Speed, accuracy, and scalability — without the enterprise price tag or the workflow fragmentation.
Design-to-Proposal in One Tool
No exporting to Word, no copying BOMs into Excel, no re-drawing in a separate proposal builder. Your solar design feeds directly into the proposal. Change the design, and the proposal updates automatically.
Flat Pricing, Unlimited Projects
Per-project fees punish high-volume teams. SurgePV charges per user per year. Model 10 projects or 1,000 — your software cost stays predictable. See pricing.
Cloud-Based, Multi-User Collaboration
Designers, sales engineers, and project managers work in the same project file. No version conflicts, no emailed PDFs with outdated numbers. Real-time collaboration keeps everyone aligned.
Global Market Ready
Multi-currency, multilingual, and not locked to US tax incentives or financing products. SurgePV serves EPCs in Europe, Asia-Pacific, Latin America, and North America from the same platform.
Simple Pricing for Commercial Teams
No per-project fees. No MW-based tiers. One flat annual rate per user. Scale your pipeline without scaling your software costs.
