TL;DR: SurgePV is the best all-in-one solar software for Romania in 2026 — combining design, automated SLD generation, bankable P50/P90 simulations, and professional proposals with prosumer net billing modeling at $1,499/user/year. Aurora Solar ranks second for enterprise residential volume. PVsyst is the gold standard for simulation-only needs. HelioScope handles fast commercial layouts. OpenSolar is the best free option.
Romania’s solar market is exploding. 5.5 GW installed. 2-3 GW added every year. The target: 10+ GW by 2030 (SolarPower Europe).
But most solar software was not built for Romania. Prosumer net billing under Law 184/2018. Casa Verde Fotovoltaice subsidy calculations. DSO connection documentation for E-Distributie, DEER, and Delgaz Grid. ANRE tariff compliance. IEC/CENELEC electrical standards. These are not edge cases — they are every single project you work on.
The wrong platform means manual workarounds on every deal. The right one handles all of it natively.

Overall Score: 95/100
Why SurgePV Ranks #1
SurgePV is the only platform that combines AI-powered design, automated electrical engineering, bankable simulations, and professional proposal generation in a single cloud-based workflow. For Romanian EPCs and installers, this eliminates tool fragmentation entirely.
Complete workflow in one platform. Design, simulate, generate SLDs, and deliver proposals — all without leaving SurgePV. No AutoCAD. No Excel. No PVsyst export. A typical commercial project takes 30-45 minutes vs 2.5-3 hours with fragmented tools.
Prosumer net billing modeling. Calculates self-consumption economics under Law 184/2018 — grid injection at ANRE reference price, battery storage impact, and day/night tariff analysis.
Automated SLD generation. Generates permit-ready single line diagrams in 5-10 minutes, meeting IEC/CENELEC standards for Romanian DSO approval.
Casa Verde subsidy integration. Incentive calculators show pre- and post-subsidy payback periods directly in proposals.
Did You Know?
Romania’s solar irradiance ranges from 1,200-1,400 kWh/m²/year, making accurate simulation software essential for bankable energy yield predictions. Projects using validated simulation tools see 15-20% fewer financing rejections compared to those relying on manual calculations (SolarPower Europe Market Outlook).
Key Strengths
- Complete Workflow: Design + electrical + simulation + proposals in one platform
- Automated SLD Generation: 5-10 min vs 2-3 hrs AutoCAD per project
- Prosumer Compliance: Net billing per Law 184/2018 with Casa Verde calculator
- Bankable P50/P90: +/-3% vs PVsyst accuracy for Romanian lenders. Your financing applications include the bankability data lenders actually require — not just optimistic P50 estimates that get rejected.
- Native Carport and Tracker: Only platform with built-in carport design and solar tracker support. With Romanian commercial parking lot and ground-mount projects growing, this is a competitive advantage.
Limitations
- Newer Brand: Less established than Aurora or PVsyst
- Cloud-Only: No desktop application
- Community Size: Growing but smaller user base
Real-World Example
A growing EPC in Bucharest with both residential and commercial projects was paying over $12,000/year for separate design, simulation, and CAD licenses — and still spending 15 hours per week on tool-switching overhead. After consolidating to SurgePV at $4,497/year (3-user plan), they freed up two full working days per week and cut their software costs by 63%.
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.

Why Most Romanian Solar Companies Overpay for Software
Romanian solar projects operate under a specific regulatory stack: Prosumer Law 184/2018, ANRE tariff regulation, Casa Verde Fotovoltaice subsidies, DSO connection processes, and IEC/CENELEC electrical standards. Software that handles US regulations but stumbles on Romanian prosumer economics wastes your time with manual workarounds.
The typical Romanian EPC without integrated solar software uses 5 separate tools and spends 2.5-3 hours per commercial project switching between them. SurgePV’s integrated platform reduces this to 30-45 minutes.
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.

When You May Not Need Advanced Solar Software
Not every solar project requires comprehensive design and simulation platforms. Consider simpler alternatives if:
- Small residential projects with standard layouts — Basic design tools or manufacturer calculators may suffice for simple rooftop arrays with minimal shading complexity.
- Engineering is outsourced — If your company uses external engineering services, you may only need proposal and CRM tools rather than full design platforms.
- Very limited project volume — Teams handling fewer than 5 projects per year may find that manual AutoCAD workflows and spreadsheet modeling are more cost-effective than software subscriptions.
- Non-technical sales teams — Sales-focused companies without in-house engineers may only require proposal generation tools rather than technical design software.
However, most EPCs, developers, and medium-to-large installers benefit from integrated platforms that reduce manual work and improve accuracy. With strict DSO requirements for electrical documentation, manual workflows create bottlenecks that delay project approvals and increase labor costs.
Bottom Line
For Romania EPCs and installers, SurgePV delivers the most complete design-to-proposal workflow with automated SLD generation, bankable P50/P90 simulations, and integrated proposals — all at $1,899/year for 3 users. Book a demo to see it in action.
