What Makes the Best Solar Design Software in Brazil
The best solar proposal generation for Brazil must meet these criteria:
1. ANEEL Distributed Generation Compliance
Brazil’s solar market is dominated by distributed generation (GD) under ANEEL Resolution 1.059/2023. Software must:
- Model net metering (Sistema de Compensação de Energia Elétrica) compensation credits accurately
- Support micro (75 kW or under) and mini (75 kW to 5 MW) GD classifications
- Calculate grid connection parameters per ANEEL interconnection rules
- Generate documentation for utility applications (Parecer de Acesso)
Why it matters: Non-compliant designs get rejected by utilities (concessionárias), causing costly redesigns and project delays.
2. ABNT NBR Electrical Standards Support
Software must generate electrical diagrams compliant with Brazilian standards:
- ABNT NBR 5410:2004 — Low-voltage electrical installations (cable sizing, protection devices)
- ABNT NBR 16690:2019 — Grid-connected PV system installation requirements
- ABNT NBR 16274:2014 — Inverter minimum requirements for grid connection
Single-line diagrams (SLDs) must meet utility application standards.
Why it matters: Utilities require ABNT-compliant documentation for interconnection approval. Non-compliant designs face rejection.
3. Brazilian Component Database (INMETRO-Certified)
The best tools include:
- INMETRO-certified inverters and modules (required for grid connection)
- Brazilian distributor pricing in Reais (R$)
- Local availability and lead times
- Integration with major Brazilian suppliers (Solfácil, Aldo, Renovigi)
Why it matters: Using non-certified equipment causes project delays and utility rejections. Accurate Brazilian pricing is essential for competitive proposals.
4. Portuguese Language Support
Professional tools must support:
- Portuguese UI (user interface) or at minimum Portuguese outputs
- Proposal templates in Portuguese for client presentations
- Technical documentation in Portuguese for utility applications
Why it matters: Clients expect professional proposals in Portuguese. English-only tools create extra work and hurt close rates.
5. Bankability for Brazilian Financiers
Simulations must be accepted by Brazilian banks and lenders:
- BNDES (Banco Nacional de Desenvolvimento Econômico e Social): National development bank for solar projects
- Banco do Brasil, Caixa Econômica Federal: Major consumer solar lenders
- Private financiers (solar loan specialists like Solfácil, BV Financeira)
P50/P90 reports for utility-scale projects. Energy yield calculations using INMET or SWERA weather data.
Why it matters: Projects can’t secure financing without bankable reports.
6. Regional Weather Data Accuracy
Brazil has significant climatic variation:
- Northeast (Bahia, Ceará, Piauí): High irradiation (5.5–6.5 kWh/m²/day)
- South (Rio Grande do Sul, Paraná, Santa Catarina): Lower irradiation (4.0–5.0 kWh/m²/day)
- Southeast (São Paulo, Rio de Janeiro, Minas Gerais): Moderate (4.5–5.5 kWh/m²/day)
Software must use Brazilian meteorological data (INMET preferred) for accurate energy yield predictions. Inaccurate weather data leads to over- or under-promising system performance, damaging installer reputation and project financials.
Decision Matrix: Which Software for Your Use Case?
| Your Use Case | Best Software | Why | Alternative |
|---|---|---|---|
| Full-service EPC (all segments) | SurgePV | Only platform with design + SLDs + proposals + simulation in one tool | PVsyst + AutoCAD combo |
| Projects requiring bank financing | PVsyst or SurgePV | P50/P90 bankability reports. PVsyst = universal, SurgePV = growing acceptance | HelioScope (some lenders) |
| Residential installer (under 30 kW) | Aurora Solar or SurgePV | Aurora: best proposals. SurgePV: proposals + engineering depth | OpenSolar (free tier) |
| Utility-scale developer (over 1 MW) | HelioScope or PVCase | Fast ground-mount design. Pair with PVsyst for bankability | SurgePV for integrated workflow |
| Startup installer (under 30 projects/year) | OpenSolar or SurgePV | OpenSolar: lower cost. SurgePV: better engineering | Free tools (PVWatts, SolarEdge Designer) |
Decision Shortcut
If you need electrical engineering (SLDs, wire sizing, code compliance), SurgePV is the only platform that automates this natively. If you’re simulation-only, PVsyst is the gold standard. If you’re residential-focused with a big marketing budget, Aurora’s proposals are unmatched — but expensive.
