TL;DR: SurgePV is the best solar proposal software for Iran — automated proposal generation with accurate financial modelling and regulatory compliance. OpenSolar offers a free entry tier for smaller installers.
Iran’s 5,000 MW Solar Target Runs on Proposals. Most EPCs Still Build Them Manually.
Iran is pushing toward 5,000 MW of solar capacity by 2027. SATBA Feed-in-Tariff contracts guarantee $0.063–0.073/kWh for 20 years. The economics work.
The pipeline is real. Kerman, Yazd, and Semnan are filling with utility-scale projects.
But winning those SATBA FIT tenders takes more than competitive pricing. It takes professional, bankable proposals — fast.
Right now, most Iranian EPCs build SATBA tender documents by stitching together outputs from three or four separate tools. PVsyst generates the simulation. AutoCAD produces electrical diagrams. Excel handles 20-year financial projections. Someone assembles it all into a Word document. The process takes 2–4 weeks per tender. Meanwhile, the tender deadline moves closer, and competitors who move faster submit first.
The proposal challenge is even harder than it looks. SATBA tenders require P50/P90 production guarantees, IEC compliance documentation for Tavanir grid connection, 50% local content tracking in the bill of materials, and 20-year FIT revenue projections. The best solar proposal software for Iran must handle all of these while cutting turnaround from weeks to hours.

SurgePV — Best End-to-End Platform for Iranian EPCs
Target Users: Utility-scale EPCs pursuing SATBA FIT tenders (10–100 MW), commercial installers, engineering firms, and solar developers requiring bankable proposals with local content compliance.
SurgePV is the only cloud-based platform combining AI-powered solar design, bankable simulations, and professional proposals in one integrated workflow. For Iranian EPCs, that integration addresses the core problem: you can produce SATBA-compliant tender documents — with P50/P90 guarantees, IEC-compliant SLDs, local content BOMs, and 20-year FIT financial projections — without switching between separate tools.
Here is why that matters for SATBA tenders. When you use PVsyst for simulation, AutoCAD for electrical, and Excel for financials, every data transfer introduces risk. The production numbers in your simulation do not automatically match the numbers in your financial model. The component list in your design does not automatically populate your local content calculation. Manual assembly across tools takes 2–4 weeks and leaves room for the inconsistencies that cost you tenders.
SurgePV compresses that into hours. Design flows into simulation flows into proposal. One data set. One workflow. One document package.
Pro Tip
SATBA FIT tenders are price-competitive. The EPC with faster proposal turnaround can iterate on more tender submissions per cycle. SurgePV’s integrated workflow does not just save time — it lets you respond to more tenders per quarter, increasing your win probability through volume.
Key Features for Iran
SATBA FIT Proposal Generation
SurgePV produces professional, customizable proposal packages suitable for SATBA tender submissions. Templates support branded cover pages, technical specifications, equipment lists, and financial summaries. Export to PDF and DOCX formats that SATBA evaluators expect.
Proposals include 3D site visualizations, system layouts for ground-mount and tracker installations, and equipment specifications pulled directly from the design. No manual assembly from separate tools.
Bankable P50/P90 Production Guarantees
SATBA requires P50/P90 production guarantees for FIT contract approval. SurgePV’s 8,760-hour simulation achieves ±3% accuracy versus PVsyst — meeting SATBA standards for bankability. The simulation accounts for Iran’s high-irradiation climate (1,800–2,200 kWh/m²/year, southern regions reaching 2,500+), desert temperatures (45–50°C), and 2–5% monthly soiling losses.
For most utility-scale projects under 100 MW, ±3% accuracy meets SATBA standards. PVsyst remains the gold standard for the largest developments, but SurgePV’s bankability meets the threshold SATBA evaluators accept.
20-Year FIT Financial Modeling
The financial modeling tool projects 20-year revenue at SATBA FIT rates ($0.063–0.073/kWh). IRR, NPV, payback period, LCOE, and cash flow analysis model the full contract term. Degradation assumptions, O&M cost escalation, and inflation adjustments reflect real project economics.
For commercial projects outside the FIT structure, the platform models self-consumption savings, net metering benefits, and custom financing scenarios.
Local Content BOM Tracking
SATBA requires 50% Iranian-manufactured components for FIT eligibility by 2027. SurgePV’s bill of materials generation tracks component origin, calculating local content percentage automatically. The 70,000+ module database includes Iranian-manufactured panels, letting you verify compliance before submission rather than discovering gaps after.
Integrated Design-to-Proposal Workflow
Design, simulation, electrical SLDs, and proposals in one cloud platform. No data re-entry between PVsyst, AutoCAD, and Excel. Real-time collaboration across distributed teams — Tehran headquarters, Kerman project sites, Yazd field offices.

What to Look for in Solar Proposal Software for Iran
Choosing the right solar proposal software for the Iranian market requires evaluating capabilities beyond generic template generation. Here are the criteria that matter:
SATBA FIT Proposal Compliance
SATBA tenders require P50/P90 production guarantees, IEC compliance documentation, 50% local content BOM, and 20-year FIT financial projections. Software that cannot generate all four forces manual assembly — the 2–4 week bottleneck that costs Iranian EPCs tender wins.
Bankable Simulation Integration
Proposals without bankable simulation data get rejected. The best solar proposal software integrates simulation into the proposal workflow, so production numbers flow directly into financial projections without manual re-entry. SurgePV’s ±3% accuracy versus PVsyst meets SATBA standards for projects under 100 MW.
20-Year FIT Financial Modeling
Iran’s FIT contracts run 20 years at $0.063–0.073/kWh. Proposals need IRR, NPV, payback period, and annual cash flow projections reflecting real degradation assumptions and O&M cost escalation. Generic US-market financial templates do not model Iranian FIT economics correctly.
Local Content Tracking
SATBA’s 50% Iranian-manufactured components requirement means proposals must document component origin. Software with built-in Iranian manufacturer databases and automatic local content percentage tracking removes a manual compliance step that commonly causes submission errors.
Speed and Turnaround
SATBA tender cycles are competitive. The EPC that submits a complete, bankable proposal first has an advantage. Software that cuts proposal assembly from 2–4 weeks to hours — without sacrificing documentation quality — directly increases tender win rates.
