TL;DR: SurgePV is the best all-in-one solar platform for Brazil — design, automated electrical engineering, bankable P50/P75/P90 simulations, and Portuguese proposals in one workflow with built-in ANEEL compliance. Aurora Solar leads for residential mobile sales. PVsyst remains the gold standard for utility-scale bankability. HelioScope suits C&I designers already on Aurora. OpenSolar works for budget-conscious residential installers.
Brazil just passed 40 GW of installed solar capacity. That is not a typo.
The country that most of the solar world ignored five years ago is now Latin America’s undisputed solar leader — and the growth is not slowing down. ABSOLAR reports continued distributed generation expansion driven by ANEEL’s net metering framework, state-level ICMS exemptions, and electricity prices that make solar payback periods genuinely attractive (3 to 5 years in most regions).
But here is the problem that 10,000+ Brazilian installers face every day: most solar design software was not designed for this market. ANEEL Resolution 1.059/2023 created a unique regulatory environment. The Marco Legal da Geracao Distribuida (2022) changed the rules on compensation credits.
ABNT NBR electrical standards differ from NEC or IEC. INMETRO-certified components are mandatory. And clients expect everything in Portuguese — proposals, financial projections, technical documentation.
Using software built for the American or European market means constant workarounds. Manual tariff inputs. Translated proposals that read like Google Translate output. Financial models that don’t account for bandeira tarifaria (the tariff flag system) or CONFINS/PIS tax impacts. That costs you hours per project and credibility with every client.

Best Solar Software in Brazil (Detailed Reviews)
Pro Tip
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 strong — but expensive.
SurgePV — Best All-in-One Solar Platform for Brazil
Target Users: Residential installers, C&I EPCs, solar designers, sales teams, and developers needing end-to-end workflows with ANEEL compliance.
SurgePV is the only cloud-based platform that combines AI-powered design, automated electrical engineering, bankable simulations, and professional proposals in a single workflow. For Brazilian teams, that means one tool from roof modeling to signed contract.
No more exporting designs to AutoCAD for SLD generation. No more switching to PVsyst for bankable numbers. No more rebuilding the same data in a proposal tool. One platform. One workflow. One source of truth.
Key Features for Brazil
Design and Engineering
AI-powered roof modeling creates 3D models from satellite imagery in 15 to 20 minutes — versus 45 to 60 minutes manually. For Brazilian rooftops with complex tile patterns and irregular shapes common in residential neighborhoods, this saves real time.
Automated SLD generation is the standout feature that separates SurgePV from every other platform in this list. Manual AutoCAD SLDs take 2 to 3 hours per commercial project. SurgePV generates code-compliant electrical single line diagrams in 5 to 10 minutes. That is not a marginal improvement — that is eliminating an entire bottleneck from your workflow.
Wire sizing calculations follow electrical standards automatically, including temperature correction and conduit fill adjustment. No more spreadsheet calculations. No more engineering errors that cause utility rejections.
ABNT NBR-compliant electrical diagram outputs (NBR 5410, 16690, 16274) meet Brazilian regulatory requirements. INMETRO-certified component database ensures you are designing with approved modules and inverters.
Simulation and Bankability
Brazilian weather data integration (INMET and global sources) ensures accurate production estimates for Brazil’s 1,500 to 2,200 kWh/m² irradiance range — from the high-irradiance Northeast (Bahia, Ceara) to the more temperate South (Rio Grande do Sul).
P50/P75/P90 bankability reports are accepted by BNDES, Banco do Brasil, and private lenders. Aurora Solar provides only P50 estimates. When your bank requires P75 or P90 conservative metrics for financing approval, that is a critical gap.
8760-hour shading analysis with +/-3% accuracy versus PVsyst. Detailed loss analysis covering soiling, shading, degradation, and inverter clipping.
Net metering credit modeling per ANEEL Resolution 1.059/2023 calculates compensation credits accurately for both micro and mini distributed generation classifications.
Proposals and Sales
Portuguese proposal templates with professional Brazilian Portuguese — not machine-translated output. Correct technical terminology: Sistema de Compensacao, Geracao Distribuida, Periodo de Retorno.
ROI calculations in R$ with Brazilian electricity tariffs pre-loaded for major utilities. Before-and-after bill comparison charts. Monthly savings projections over 25 years with realistic degradation assumptions.
Financing integration with manual input for Brazilian loan terms (12 to 120 months, 1.5 to 3% monthly interest). Solfacil and BV Financeira API integrations under development.
Complete proposals — design, simulation, financial model, Portuguese output — in under 10 minutes. That changes the competitive dynamic when Brazilian clients expect responses within 24 to 48 hours.
Real-World Example
A mid-size EPC team handling both residential and C&I projects across Minas Gerais was spending 2.5 hours per commercial project creating SLDs in AutoCAD, then separately running simulations and building proposals. After switching to SurgePV, the entire workflow — design through proposal — dropped to under 45 minutes. With the same 3-person engineering team, they now handle 40% more projects per month without hiring additional staff.
You might be wondering: with 70,000+ projects powered globally, why isn’t SurgePV as well-known as Aurora or PVsyst in Brazil? PVsyst has had a 30-year head start. Aurora has spent hundreds of millions on marketing. SurgePV launched more recently and built its reputation on the engineering depth that those platforms lack — particularly automated electrical engineering, which no other platform offers natively.

What Makes the Best Solar Software in Brazil
The best solar software for Brazil must handle requirements that generic international platforms miss. Here is what separates platforms that work in Brazil from those that create workarounds.
1. ANEEL Compliance
Software must support ANEEL Resolution 1.059/2023 distributed generation rules. That includes net metering credit calculations, micro versus mini GD classifications, the transition tariff (Fio B) for new systems under the Marco Legal da GD, and utility interconnection documentation.
Non-compliant software means manual engineering review for every project. That adds hours and increases the risk of utility application rejections. In a market where speed wins deals, regulatory compliance built into the software is a requirement, not a nice-to-have.
2. ABNT NBR Standards
Brazilian electrical standards differ from NEC (US) and IEC (Europe). Software must generate electrical diagrams compliant with NBR 5410 (electrical installations), NBR 16690 (PV systems), and NBR 16274 (PV performance). INMETRO-certified component databases are mandatory.
Submitting designs with non-compliant electrical documentation gets your utility application rejected. Fixing it after the fact costs more time than getting it right the first time. Software with ABNT compliance built in eliminates this risk.
3. Portuguese Language Output
Professional proposals and client-facing documents must be in Brazilian Portuguese — properly localized with correct technical terminology, not just translated.
Clients compare quotes from three to five installers. English-language or poorly translated proposals signal “foreign company that doesn’t understand our market.” Correct Portuguese signals credibility and local expertise.
4. Brazilian Component Database
Software must include INMETRO-certified inverters and modules with local pricing in R$. Software without Brazilian component databases forces manual BOM creation — adding 30 to 60 minutes per project.
5. Bankability for Brazilian Financiers
For projects requiring bank financing — which includes most C&I projects and utility-scale developments — software must produce reports accepted by BNDES, Banco do Brasil, and private lenders.
P50/P75/P90 estimates are the language financiers speak. Software providing only P50 (median) without P75 or P90 (conservative) limits your ability to secure project financing. That directly impacts your business pipeline.
6. Workflow Efficiency
Brazilian installers face extreme competitive pressure — 10,000+ installers in a fast-growing market. Software that streamlines design through proposal in one workflow, eliminating tool-switching, gives teams a measurable productivity advantage.
Here is the math: if you save 1.5 hours per project by eliminating AutoCAD for electrical and avoiding data re-entry between tools, and you handle 50 projects per month, that is 75 hours saved monthly. At R$100/hour loaded labor cost, that is R$7,500/month in productivity gains. Software paying for itself is arithmetic, not theory.

Transparency Note
SurgePV publishes this content. We are transparent about this relationship. This comparison acknowledges PVsyst as the undisputed gold standard for bankable simulation and Aurora Solar’s leadership in residential mobile sales. We do not claim SurgePV is the right choice for every use case — we present it as the strongest all-in-one platform for Brazilian EPCs and installers who need design, electrical engineering, simulation, and proposals in one workflow. See our editorial standards.
Bottom Line: Best Solar Software for Brazil
For end-to-end workflows: SurgePV offers the most complete solar proposal software platform for Brazil. Design, automated electrical engineering, bankable P50/P75/P90 simulations, and Portuguese proposals — all in one tool. Teams reduce design time by 70% versus manual workflows and eliminate AutoCAD dependency. At $1,899/year for 3 users, it delivers the strongest value for Brazilian EPCs and installers at any scale.
For residential installers prioritizing mobile sales: Aurora Solar provides industry-leading AI roof modeling and on-site iPad/tablet proposal generation. Strong proposals. Strong CRM integration. But premium pricing ($1,908 to $3,108/year per user), no electrical engineering, and P50-only bankability limit its value for C&I work or bank-financed projects.
For utility-scale EPCs requiring maximum bankability: PVsyst remains the gold standard for financier-accepted simulation reports. Every major Brazilian bank accepts PVsyst P50/P90 reports. But it is simulation only — no design, no proposals, no electrical engineering. Use alongside a design platform like SurgePV for complete workflows.
For C&I designers already using Aurora: HelioScope offers fast commercial rooftop design that integrates with Aurora’s proposal platform. Good for quick iterations on commercial flat-roof layouts. No standalone proposal or electrical engineering capabilities.
For budget-conscious residential installers: OpenSolar delivers fast proposals and basic design at accessible pricing. Good for high-volume standardized residential systems. Limited design tools, no electrical engineering, and no bankability restrict growth into C&I projects.
Brazil’s distributed generation market added massive capacity in 2025 alone. The consorcio solar (solar cooperative) model is expanding. Installers who automate their workflows today — design through proposal, with ANEEL compliance and Portuguese output — will capture the next wave of growth. Those still switching between Excel, AutoCAD, and separate proposal tools will fall behind.
Your solar design software choice is a competitive advantage. Not a procurement checkbox.
