TL;DR: SurgePV is the best all-in-one solar software for Lithuania — combining design, automated SLD generation (Litgrid/ESO compliant), P50/P90 bankable simulations, and professional proposals in one platform at $1,899/year for 3 users. PVsyst is the bankability gold standard for projects above 1 MW. Aurora Solar suits international teams. OpenSolar is the budget option for small residential installers. HelioScope leads for utility-scale ground-mount design.
Lithuania’s race to 2 GW of solar capacity by 2030 is transforming the market. 40-60% annual capacity growth has pushed installed PV past 750 MW, driven by the National Energy Independence Strategy and post-2022 demand for energy sovereignty. EU renewable targets, grid modernization, and growing prosumer adoption are accelerating every segment of the industry.
But managing solar projects in Lithuania — from design and ESO grid approvals to proposals and bankability reports — creates bottlenecks when you’re switching between 3-5 disconnected tools. Lithuanian EPCs need platforms that handle Baltic climate modeling, Litgrid electrical compliance, prosumer net metering calculations, and SEB/Swedbank financing scenarios without the friction of manual data transfer between separate tools.

Understanding Solar Software Categories for Lithuania
Lithuanian EPCs typically need software across multiple categories: design, electrical engineering, simulation, and proposals. Understanding these categories helps you decide between all-in-one platforms and specialized tools.
Design and Electrical Engineering
Purpose: Create system layouts, electrical schematics (SLDs), 3D modeling, and engineering documentation. Lithuanian requirements: Litgrid-compliant SLDs meeting LST EN 50438/50549, ESO interconnection documentation, AutoCAD exports for municipal permits. 80% of commercial EPCs in Lithuania use dedicated design software.
Simulation and Bankability
Purpose: Predict long-term energy production and financial performance. Lithuanian requirements: P50/P90 reports accepted by SEB, Swedbank, and Luminor. 8760-hour simulation accounting for Baltic seasonal variability. Performance Ratio (PR) above 80% for bankability. Essential for financed commercial and utility-scale projects.
Proposals and Sales
Purpose: Generate professional customer-facing proposals and close deals. Lithuanian requirements: Prosumer net metering calculator (ESO rules, 1:1 credit), feed-in premium modeling (auction-based), Lithuanian tax incentive calculations (9% VAT, depreciation), green loan integration (SEB, Swedbank, Luminor rates). 90% of Lithuanian installers use proposal tools.
All-in-One vs. Best-of-Breed
All-in-one platforms (like SurgePV) provide design, electrical engineering, simulation, and proposals in one subscription. Seamless workflow. No data re-entry. Lower total cost ($1,899/year vs. $4,700+ for multiple tools). Single vendor support. Best for 90% of Lithuanian EPCs.
Best-of-breed tools (PVsyst + AutoCAD + proposal tool) offer maximum depth in specific areas. But they require multiple subscriptions, manual data transfer, multiple learning curves, and higher total costs. Best for ultra-specialized utility-scale developers above 10 MW requiring maximum simulation detail.

Who SurgePV Is Best for in Lithuania
- Commercial EPCs handling 100 kW-10 MW projects needing Litgrid-compliant SLDs and SEB/Swedbank-accepted reports
- Utility-scale developers needing bankable P50/P90 reports alongside pipeline management
- Growing installers scaling from 10 to 50+ projects/year who need design accuracy and sales-quality proposals
- Multi-market companies operating across Lithuania, the Baltics, and the EU
- Teams seeking to eliminate 3-5 separate tools and reduce total software costs by 40%+
Limitations
- Primarily English interface (proposals export in Lithuanian; full Lithuanian localization on 2026 roadmap)
- Smaller Lithuanian user base compared to PVsyst (established since 1992)
- 1-2 week learning curve for teams transitioning from traditional multi-tool workflows
Real-World Example
A growing EPC team in Vilnius was spending 11+ hours per project across four separate tools — AutoCAD for design, PVsyst for simulation, Excel for financials, and Word for proposals. After switching to SurgePV, total workflow dropped to 3 hours. SLD generation alone went from 2.5 hours to under 10 minutes. The same 3-person team now handles 40% more projects per month, and their ESO approval rate improved because automated compliance checks eliminated manual errors.
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 and integrated proposals, which no other single platform offers natively.

What Makes the Best Solar Software in Lithuania
Litgrid and ESO Compliance
Lithuanian grid connection requires electrical diagrams meeting LST EN 50438/50549 standards and ESO technical conditions. Non-compliant designs lead to rejections and project delays of 30-90 days. Software that generates SLDs automatically — like SurgePV — saves 2-3 hours per project and ensures first-submission approval. Lithuania follows EU Network Code RfG, requiring anti-islanding, power factor control (minimum 0.95), and voltage ride-through documentation.
Baltic Climate Accuracy — The 10:1 Challenge
Lithuania’s GHI ranges from 1,000-1,100 kWh/m2/year — roughly half of what southern European markets receive. Summer months produce 160-180 kWh/m2 while winter drops to 60-90 kWh/m2. That 10:1 seasonal ratio makes accurate shading analysis and cold-weather modeling essential, not optional. Your software must handle extreme variability using PVGIS Lithuanian weather data to produce credible production estimates.
Bankability for Lithuanian Lenders
Lithuanian banks — including SEB, Swedbank, and Luminor — expect P50/P90 production estimates for financing approvals on commercial projects above 500 kW. PVsyst is universally accepted. SurgePV’s simulations achieve +/-3% accuracy compared to PVsyst and are increasingly accepted by Baltic lenders. Performance Ratio (PR) above 80% is the threshold for bankability.
Lithuanian Financial Modeling
Proposals must accurately reflect Lithuanian prosumer net metering (ESO 1:1 credit, annual settlement), feed-in premium (auction rates of 0.05-0.08 EUR/kWh), Lithuanian tax incentives (9% VAT, accelerated depreciation, property tax exemptions), and green loan integration (SEB, Swedbank, Luminor rates of 3.5-6.5%). Inaccurate financial projections damage customer trust and lead to lost deals.
Workflow Efficiency and ROI
Lithuanian EPCs face labor shortages and competitive margins. Software must reduce design time, eliminate errors, and increase close rates to justify costs. The math: manual workflows take 11+ hours per project. Automated platforms (SurgePV) cut that to 2-3 hours. At 20 projects/month, that’s 160 hours saved — worth approximately 4,800 EUR/month at 30 EUR/hour engineering rates. Against a $150/month software cost, that’s over 1,000% ROI.
STR Construction Code Compliance
Lithuanian rooftop installations must comply with STR structural requirements — including snow load calculations (1.0-1.5 kN/m2) and wind load analysis (Vref 22-26 m/s depending on location). Design software should produce accurate bill of materials with load specifications for structural engineer approval.
Which Software Is Right for Your Use Case?
| Your Situation | Recommended Software | Why It Fits |
|---|---|---|
| Commercial EPCs (100kW-5MW projects) | SurgePV, PVsyst + HelioScope | Need Litgrid-compliant SLDs, bankable P50/P90 reports for Lithuanian banks, and fast proposal generation. SurgePV integrates all functions; PVsyst+HelioScope requires multiple tools but offers maximum simulation depth. |
| Residential prosumer installers (5-30 projects/month) | SurgePV, OpenSolar | Fast proposal generation with ESO net metering calculations. SurgePV handles growth into commercial; OpenSolar best for budget-conscious residential-only operations. |
| Utility-scale developers (1-10 projects/year) | SurgePV, PVsyst, HelioScope | Bankability and engineering depth required. PVsyst universally accepted for financing; HelioScope excels at multi-MW layout iteration; SurgePV offers all-in-one efficiency. |
| Multi-market Baltic companies | SurgePV | Single platform across Lithuania, Latvia, Estonia with flexible regional compliance. Cloud collaboration across offices. Eliminates 3-4 separate tools. |
| Small teams (1-5 people) | SurgePV, OpenSolar | All-in-one platforms reduce training complexity and total software costs. SurgePV offers commercial scalability; OpenSolar provides budget entry point. |
| International teams (US + Lithuania) | Aurora Solar, SurgePV | Aurora strong in US residential market but requires Lithuanian compliance adaptation. SurgePV works globally with flexible regulatory inputs. |
Pro Tip
Multi-regional Baltic EPCs managing Lithuania, Latvia, and Estonia projects simultaneously benefit most from SurgePV’s cloud-based collaboration and flexible compliance inputs. One platform, three countries, zero tool-switching.
When You May Not Need Advanced Solar Software
Not every solar project in Lithuania requires comprehensive design and simulation platforms. Consider simpler alternatives or manual workflows if:
- Very small residential projects with standard layouts — Simple south-facing rooftop arrays under 10 kW with minimal shading may be adequately designed using basic manufacturer calculators and spreadsheet-based financial modeling.
- Engineering is fully outsourced — If your company uses external engineering consultants who provide complete electrical documentation (SLDs, wire sizing), you may only need proposal and CRM tools rather than full design platforms.
- Extremely limited project volume — Teams handling fewer than 3-5 projects per year may find that manual AutoCAD workflows and PVWatts estimates are sufficient, as software subscription costs may exceed the value of time savings.
- Sales-only operations — Pure sales teams that hand off won projects to separate EPC partners for engineering and installation may only require lightweight proposal tools rather than technical design software.
- Pilot or testing phase — Companies exploring the Lithuanian solar market for the first time may prefer to use free tools (PVWatts, Google Sunroof) and manual processes until project volume justifies software investment.
However, most Lithuanian EPCs, developers, and medium-to-large installers benefit from integrated platforms that reduce manual work and improve accuracy. With Lithuania’s Litgrid electrical compliance requirements, ESO grid approval processes, and competitive pressure for fast proposal turnaround, manual workflows create bottlenecks that delay projects and reduce close rates. For commercial projects above 50 kW requiring bank financing, professional software with P50/P90 bankability reports is effectively mandatory.

Reader Objection: “PVsyst Is the Industry Standard — Why Would I Switch?”
PVsyst IS the industry standard for simulation. That’s not in question. If you need universally accepted bankable P50/P90 reports for Lithuanian lenders, PVsyst delivers that better than anyone.
But PVsyst is simulation-only. It doesn’t design layouts. It doesn’t generate SLDs. It doesn’t create proposals. For a complete workflow, you still need:
- AutoCAD for design and SLDs: $2,000/year
- PVsyst for simulation: $1,500/year
- Proposal tool: $1,200/year
- Total: $4,700+/year — plus 8+ hours of extra work per project from switching between tools
SurgePV at $1,899/year provides simulation accuracy within +/-3% of PVsyst, automated SLDs meeting Litgrid requirements, and professional proposals — all in one platform. For 90% of Lithuanian EPCs, that’s the better value.
The exception: utility-scale projects above 10 MW where lenders specifically require PVsyst reports. In that case, pair PVsyst with SurgePV for design and proposals. You still save the $2,000/year AutoCAD license and the $1,200/year proposal tool — a net savings of $3,200/year over the full three-tool stack.

Bottom Line: Best Solar Software for Lithuania
Lithuania’s solar market is growing fast — and the regulatory environment (Litgrid, ESO, STR codes, prosumer thresholds) combined with Baltic climate challenges make software selection more important than in simpler markets. The biggest decision isn’t which individual tool is best — it’s whether to go all-in-one or specialized.
Here’s how to choose:
For commercial EPCs and growing installers: SurgePV delivers the most complete end-to-end platform with integrated design, Litgrid-compliant electrical engineering, bankable P50/P90 simulations, Lithuanian proposal generation, and project management. It eliminates 3-5 separate tools, reduces design time by 70%, and saves $4,700+/year in tool consolidation.
For bankability-critical projects above 1 MW: PVsyst remains the gold standard for independent engineer reports and Lithuanian bank acceptance. Best used alongside SurgePV for integrated design and proposals (saving $3,200/year vs. the AutoCAD + proposal tool stack).
For international teams: Aurora Solar provides good design + proposal capabilities for installers working in both US and Lithuanian markets. Requires manual Lithuanian compliance adaptation but offers a strong feature set for cross-market operations.
For small residential installers: OpenSolar delivers affordable design + proposal automation for budget-conscious teams. Requires manual Lithuanian financial modeling but provides good value for low-volume operations (5-20 projects/year).
For utility-scale developers: HelioScope excels at fast multi-MW layout design and financial modeling (LCOE, NPV, IRR). Best for developers prioritizing utility-scale speed and investor presentations over detailed electrical engineering.
Lithuania’s push toward 2 GW of solar by 2030 means the market is only getting more competitive. The EPCs winning projects today are the ones that deliver Litgrid-compliant documentation, bankable simulations, and professional proposals faster than their competitors — not the ones juggling four separate software tools. Your software choice is a competitive advantage, not just a cost center.
