TL;DR: SurgePV is the best solar proposal software for Romania in 2026 — combining design integration, prosumer financial modeling per Law 184/2018, Casa Verde subsidy calculations, and professional EUR/RON proposals in one cloud platform. Aurora Solar ranks second for visual enterprise proposals. OpenSolar is the best free option. PVsyst + manual workflows suit utility-scale simulation-only needs.
Speed wins deals. In Romania’s prosumer market, customers collect 3-6 quotes before signing. Residential installations are growing 40-50% year-over-year as Casa Verde Fotovoltaice subsidies and rising electricity prices push homeowners toward solar.
Here is the problem. Most Romanian installers still build proposals in Excel. A 5 kW prosumer system quote takes 1-2 hours of manual work. Meanwhile, your competitor using automated solar proposal software sends a professional, accurate quote in 15-20 minutes. The customer signs before your spreadsheet is even formatted.
That gap is not just inconvenient. It is costing you deals every single week.

Proposal Speed: 15-20 minutes from design to finished proposal
Overall Score: 95/100
Why SurgePV Ranks #1
SurgePV combines solar design, bankable simulations, electrical engineering, and professional proposals in a single cloud platform. For Romanian installers, this means one workflow from address to signed contract.
Prosumer financial modeling built in. SurgePV calculates self-consumption savings under Law 184/2018, grid injection credits at ANRE-regulated reference prices, and the impact of battery storage on prosumer ROI.
Casa Verde subsidy integration. The platform includes incentive calculators that show Casa Verde Fotovoltaice subsidy amounts (up to RON 20,000/~EUR 4,000) and their impact on payback period.
Design-integrated proposals. Proposals pull directly from SurgePV’s design and simulation engine, eliminating manual data transfer.
Automated SLD generation. SurgePV is the only proposal platform that also generates permit-ready single line diagrams in 5-10 minutes.
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
- Full Design-to-Proposal Integration: One platform from design to signed contract. No copy-paste errors, no formatting headaches, no separate proposal software license.
- Prosumer Net Billing: Automated calculations per Law 184/2018
- Casa Verde Calculator: Pre- and post-subsidy payback periods in proposals
- Bankable P50/P90 Reports: Bankability-grade accuracy for commercial proposals. Your financing applications include the data Romanian lenders actually require — not just optimistic estimates that get rejected.
- EUR/RON Currency Support: Dual currency display for Romanian customers. Customers see prices in their preferred currency instantly — no manual conversion that introduces rounding errors or confusion.
Limitations
- Brand Recognition: Newer brand with smaller community than Aurora
- Cloud-Only: No desktop app (requires internet)
Real-World Example
A residential installer in Transylvania generating 80+ proposals per month was juggling three tools — design software, simulation software, and spreadsheets for financials. Each proposal took 3-4 hours. With SurgePV’s unified workflow, that dropped to 45 minutes per proposal. Same-day proposals instead of next-week follow-ups. Their close rate improved because in solar sales, speed wins deals.
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.

Excel Templates — The Status Quo
Best For: Very small Romanian installers with no software budget
Pricing: Free
Proposal Speed: 1-2 hours
Overall Score: 40/100
Why Excel Ranks #5
Many Romanian installers still use Excel spreadsheets. It’s free, customizable, and familiar — but also slow, error-prone, and unprofessional. Every formula error goes straight to the customer. For an installer handling 20+ proposals per month, that’s 20-40 hours lost to manual spreadsheet work. SurgePV at EUR 1,399/year pays for itself in the first month.
The Proposal Mistakes Costing Romanian Installers Deals
Prosumer net billing economics
Under Law 184/2018, Romanian prosumers with systems up to 400 kW benefit from net billing. Your proposal must show monthly self-consumption savings, grid injection credits at ANRE-regulated reference prices, net electricity bill after solar offsets, and battery storage impact on self-consumption ratio.
Casa Verde subsidy visualization
The Casa Verde Fotovoltaice subsidy (up to RON 20,000/~EUR 4,000) is the primary purchase driver. Your proposal should clearly show system cost before subsidy, Casa Verde amount, net customer cost, and payback period with and without subsidy.
EUR/RON pricing clarity
Romanian customers think in RON for everyday expenses but compare solar prices in EUR for larger systems. Proposals should support dual currency display.
