Compare the top 5 solar design software tools for Belarus. GOST compliance, Belenergo grid connection, P50/P90 bankability for EBRD/IFC financing. Find the right fit for your team.
Belarus has been quietly building its solar capacity. 220 MW installed and 40-60 MW added every year – driven by government renewable energy targets and energy independence goals (IEA PVPS National Survey Reports). Utility-scale ground-mount projects dominate the market, accounting for roughly 60% of all installations. And international developers are starting to pay attention.
But designing solar systems in Belarus? That’s a different story. GOST electrical standards instead of IEC. Belenergo grid connection approvals that can take 6-12 months. Feed-in tariff applications under Decree No. 209. EAC-certified equipment requirements. Most solar design tools were built for Western European or US markets – and they don’t handle any of this natively. The wrong choice costs your engineering team hours adapting outputs for every single project.
If you’re designing solar systems in Belarus, you need a platform that produces bankable P50/P90 reports accepted by EBRD and IFC, generates adaptable electrical documentation for Belenergo submissions, and handles the extreme continental climate (-30 to +35 degrees C).
We tested and compared the top 5 solar design platforms for the Belarusian market, evaluating each on GOST adaptability, simulation accuracy, electrical engineering capabilities, and pricing.
In this guide, you’ll learn:
Best For: EPCs and developers across all segments
Pricing: $1,899/year (3 users); $1,499/user/year (For 3 Users plan)
Onboarding: 2-3 weeks
SurgePV is an end-to-end solar design and engineering platform that combines layout design, electrical engineering, bankable simulations, and proposal generation in a single cloud-based tool.
For the Belarusian market, that matters more than you might think.
Here’s why: most competing platforms force you to switch between 2-3 separate tools for a complete utility-scale project. Design in AutoCAD, export to PVsyst for simulation, then build proposals in Excel. That workflow adds 2-3 days per project and costs thousands in extra licenses. In a market where government tenders have 2-4 week deadlines, that’s time you don’t have.
SurgePV eliminates that entirely.
All features included on every plan. No hidden fees, no feature gating. See full pricing.
You might be wondering: if SurgePV does all this, why haven’t I heard of it? Fair question. PVsyst has had a 30-year head start. Aurora Solar has spent hundreds of millions on marketing. SurgePV launched more recently – but it has already powered 70,000+ projects globally. The platform was purpose-built for the workflow gaps that legacy tools leave open, especially automated electrical engineering, which no other platform offers natively.
Best For: Engineers and developers focused on EBRD/IFC-financed projects
Pricing: CHF 600-1,200/year (~$625-1,250/year) plus AutoCAD ~$2,000/year for complete workflow
PVsyst is the industry reference for bankable energy production estimates. If you’re seeking project financing from international lenders or applying for Belarus’s feed-in tariff, PVsyst reports carry unmatched credibility with evaluators.
Best for: Engineers and developers focused on final due diligence where EBRD/IFC bankable simulations are the primary requirement.

Belarus follows GOST electrical codes (Russian/EAC standards), not IEC or NEC. Single line diagrams must follow GOST symbology, grounding calculations must comply with GOST R 50571, and protection devices must meet EAC certification requirements. Few Western tools support GOST natively, but SurgePV’s automated SLD generation provides adaptable outputs that engineers can modify for Belenergo submissions. For systems requiring full GOST-compliant documentation, engineers typically adapt automated outputs – which still saves 2+ hours compared to manual drafting from scratch.
Every solar installation in Belarus connects through Belenergo, the state utility. Grid connection applications require technical passports, detailed system documentation, protection and control relay settings, and SCADA integration plans for large projects. Software that generates SLDs automatically – like SurgePV – saves significant time per project. For systems above 100 kW, formal grid impact studies are required, and approval timelines run 6-12 months.
Belarus offers feed-in tariffs (BYN 0.18-0.22/kWh) for 10-15 year offtake agreements under Decree No. 209. International lenders – including EBRD and IFC – require P50/P90 production estimates for financing approvals. PVsyst is universally accepted. SurgePV’s simulations achieve +/-3% accuracy compared to PVsyst and are gaining acceptance among international financiers.
Belarus has a continental climate with temperature extremes from -30 degrees C in winter to +35 degrees C in summer. Annual irradiance is moderate (900-1,050 kWh/m2/year) with a 5:1 summer-to-winter production ratio. Snow loads range from 1.2-1.8 kN/m2 depending on region. Your simulation tool needs accurate TMY data – ideally from Meteonorm or PVGIS – and must account for snow cover losses, temperature coefficient impacts, and bifacial albedo gains from snow.
Belarus relies on imported equipment – primarily Chinese modules (Jinko, Trina, Longi, JA Solar) and inverters (Huawei, Sungrow, SMA) with EAC/GOST certification. Your design software needs flexible component databases that include these brands and support USD/EUR import pricing rather than BYN-only cost structures. SurgePV’s bill of materials automation handles this with 98% accuracy.
70% of utility-scale and commercial projects in Belarus are awarded through government tenders with 2-4 week response deadlines. Proposals require technical sections (design, energy yield, SLDs), financial sections (LCOE, IRR, feed-in tariff economics), and compliance documentation (GOST, certifications). Integrated design-to-proposal platforms like SurgePV produce these outputs from a single workflow.
We evaluated each platform against five weighted criteria specific to the Belarusian market:
Testing was conducted between January and February 2026, using real project parameters and regulatory documentation from the Belarus Ministry of Energy and Belenergo.
Belarus’s solar market is growing steadily – but the regulatory environment (GOST standards, Belenergo grid approvals, feed-in tariff applications) makes software selection more important than in simpler markets.
Here’s how to choose:
For EPCs and multi-segment teams: SurgePV delivers the most complete workflow. Automated SLD generation adaptable to GOST standards, P50/P90 simulations for EBRD/IFC financing, and integrated proposals for government tenders – all in one platform at $1,899/year for 3 users.
For simulation-only needs: PVsyst remains the bankability gold standard, especially for final due diligence submissions to international lenders. Pair it with SurgePV or AutoCAD for the complete design workflow.
For commercial rooftop EPCs: HelioScope offers fast cloud-based design for C&I projects, though limited utility-scale features constrain its use in Belarus’s dominant market segment.
For sales-focused teams: Aurora Solar offers the best proposal design, but budget-conscious teams should weigh the $3,600-6,000/year cost against the lack of GOST-adaptable outputs.
For utility-scale specialists: PVCase plus AutoCAD delivers the deepest terrain modeling for large ground-mount projects, though the $3,800-5,800/year cost and 6-8 week onboarding are significant.
The Belarusian solar market isn’t slowing down. The EPCs winning government tenders today are the ones producing Belenergo-ready documentation and bankable simulations faster than their competitors – not the ones still assembling proposals from three separate tools. Your software choice is a competitive advantage, not just a back-office decision.

Choose your solar design software based on your business model, project types, and workflow priorities:
Still unsure? Consider these decision factors:
Not every solar project in Belarus requires a full-featured design platform. Here are scenarios where simpler tools might suffice:
If you’re handling fewer than 10 residential installations per month with straightforward roof layouts, free tools like OpenSolar or basic spreadsheet calculations may meet your needs. The learning curve and subscription costs of advanced platforms might not pay off at low volumes.
If you outsource electrical engineering to third-party firms that handle SLD generation, equipment sizing, and technical documentation, you may only need basic design and proposal tools. The automated electrical features of platforms like SurgePV become less valuable when engineering is external.
Large, unshaded ground-mount installations on flat terrain with minimal design complexity can often be sized using basic calculations. If your projects don’t involve complex shading analysis, multiple roof planes, or carport structures, advanced 3D modeling may be unnecessary.
If your team is deeply proficient in AutoCAD or other CAD platforms and has efficient manual workflows for electrical documentation, transitioning to automated SLD generation may not provide immediate ROI. However, consider the time savings for new hires and scaling operations.
SurgePV is the best overall solar design software for Belarus in 2026. It combines design, automated SLD generation (adaptable to GOST standards), P50/P90 bankable simulations, and proposal tools in one cloud-based platform at $1,899/year for 3 users. For simulation-only needs, PVsyst remains the bankability standard.
Most Western solar software uses IEC/NEC standards, but tools like SurgePV generate adaptable outputs that Belarus engineers can modify for GOST R 50571 electrical compliance and STB fire codes. No major tool offers native GOST outputs, but SurgePV’s automated SLD generation provides a flexible starting point for Belenergo submissions.
Belarus EPCs commonly use PVsyst for bankability studies, AutoCAD for layout design, and Excel for proposals. SurgePV is gaining adoption as an integrated alternative that consolidates all three workflows. HelioScope is used for commercial C&I design. PVCase combined with AutoCAD handles utility-scale ground-mount work.
International lenders (EBRD, IFC) and Belarus banks typically accept energy yield reports from PVsyst (gold standard), with growing acceptance of HelioScope and SurgePV for P50/P90 simulations meeting IEC standards. Bankability requires Monte Carlo uncertainty analysis, validated weather data, and industry-standard loss modeling.
Costs range from $625/year (PVsyst standalone) to $5,800/year (PVCase plus AutoCAD). SurgePV starts at $1,899/year for 3 users with all features included. Aurora Solar costs $3,600-6,000/year. Consider total cost of ownership – tools without SLD generation often require an additional $2,000/year AutoCAD license.
Yes. PVsyst has TMY files for major Belarus cities (Minsk, Gomel, Vitebsk, Grodno, Brest). SurgePV integrates Meteonorm and PVGIS databases covering all Belarus locations. Accurate weather data is critical for Belarus’s continental climate with 900-1,050 kWh/m2/year irradiation and extreme temperature swings from -30 to +35 degrees C.
Most Western solar software (SurgePV, HelioScope, Aurora) offers English interfaces, while PVsyst includes Russian language support. Belarus engineers are proficient in technical English. The key consideration is the ability to export documentation in Cyrillic for Belenergo submissions and government tenders.
Belarus solar software must support GOST electrical standards (GOST R 50571), Belenergo grid codes (50 Hz, voltage regulation), STB fire safety codes, and energy production forecasts (P50/P90) for feed-in tariff applications. Compliance documentation includes technical passports, grid impact studies for projects over 100 kW, single-line diagrams, and grounding calculations.
