All claims are validated using publicly available and vendor-verified sources.

Introduction

Brazil’s solar market has surged to 17.5 GW of installed capacity. Distributed generation (GD) drives growth.

ANEEL’s Resolution 1.059/2023 governs net metering. ABNT NBR standards mandate electrical compliance. State-specific ICMS regulations add complexity.

The wrong software leads to utility rejections, manual rework, and lost deals in a market where 10,000+ installers compete for projects.

The best solar design software for Brazil must support ANEEL-compliant grid connection modeling, ABNT NBR electrical standards, Portuguese-language outputs, Brazilian component databases (INMETRO-certified), and net metering credit calculations.

Here’s our expert-tested ranking of the best solar design software for Brazil in 2026.

Best Solar Design Software Comparison Table for Brazil

What Makes the Best Solar Design Software in Brazil

The best solar design software 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 Compensacao de Energia Eletrica) compensation credits accuratelySupport micro (≤75 kW) and mini (75 kW to 5 MW) GD classificationsCalculate grid connection parameters per ANEEL interconnection rulesGenerate documentation for utility applications (Parecer de Acesso)

Why It MattersNon-compliant designs get rejected by utilities (concessionarias), 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 requirementsABNT NBR 16274:2014: Inverter minimum requirements for grid connectionSingle-line diagrams (SLDs) must meet utility application standards

Why It MattersUtilities 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 timesIntegration with major Brazilian suppliers (Solfácil, Aldo, Renovigi)

Why It MattersUsing 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 least Portuguese outputsProposal templates in Portuguese for client presentationsTechnical documentation in Portuguese for utility applications

Why It MattersClients 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 Economico e Social): National development bank for solar projectsBanco do Brasil, Caixa Economica Federal: Major consumer solar lendersPrivate financiers (solar loan specialists like Solfácil, BV Financeira)P50/P90 reports for utility-scale projectsEnergy yield calculations using INMET or SWERA weather data

Why It MattersProjects can’t secure financing without bankable reports. Software must produce outputs accepted by Brazilian financial institutions.

6. Regional Weather Data Accuracy

Brazil has significant climatic variation:Northeast (Bahia, Ceara, Piaui): High irradiation (5.5-6.5 kWh/m²/day)South (Rio Grande do Sul, Parana, Santa Catarina): Lower irradiation (4.0-5.0 kWh/m²/day)Southeast (Sao 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.

Why It MattersInaccurate weather data leads to over/under-promising system performance, damaging installer reputation and project financials.

Bottom Line: Best Solar Design Software for Brazil

For EPCs and installers focused on distributed generation (GD) in BrazilSurgePV offers the most complete platform with ANEEL Resolution 1.059/2023 compliance, ABNT NBR electrical outputs, Portuguese proposal generation, and Brazilian component databases (INMETRO-certified). Teams reduce design time by 70% compared to manual workflows and close deals 30% faster with professional Portuguese proposals.For residential installers needing speedAurora Solar provides fast AI-powered design and mobile sales capabilities, though net metering calculations require more manual work than SurgePV.For utility-scale EPCs requiring maximum bankabilityPVsyst remains the gold standard for financier-accepted P50/P90 reports, but lacks proposal tools and residential workflow optimization.For complex urban rooftop projects with heavy shadingPV*SOL’s 3D shading analysis is unmatched, though workflows are slower than Aurora or SurgePV.For large C&I and ground-mount projectsHelioScope excels at fast utility-scale layouts with financial modeling, but isn’t optimized for residential GD or ANEEL net metering rules.
