Austria’s solar market is booming. Growth of 30–40% per year, driven by the EAG and electricity prices at EUR 0.25–0.35/kWh. But picking the right solar design software? That is where most Austrian EPCs get it wrong.
OVE-compliant electrical documentation is mandatory. Single Line Diagrams. Wire sizing per NINorm. Protection device specs per OVE E 8001. If your software does not generate those automatically, you are stuck paying EUR 1,800/year for AutoCAD and spending 2–3 hours per project drawing them by hand. That is time and money you cannot afford to waste in a market with 8–12% margins.
We tested 5 solar design platforms specifically for the Austrian market, evaluating each on OVE compliance, engineering features, bankability, ease of use, and total cost.

Comparison Table: Best Solar Design Software for Austria
Why Most Austrian Solar Companies Overpay for Design Software
OVE compliance and Austrian electrical standards
Austrian solar installations must comply with OVE (Osterreichischer Verband fur Elektrotechnik) standards, particularly OVE R 11-1 for grid connections and OVE E 8001 for electrical safety. Your design software needs to generate SLDs showing DC and AC protection devices, wire sizing per NINorm, voltage drop analysis, grounding per OVE E 8001-5, and anti-islanding protection specifications.
Manual SLD creation in AutoCAD takes 2–3 hours per commercial project. Platforms without integrated SLD generation force EPCs to purchase AutoCAD (EUR 1,800/year) and waste 40–60 hours/year on manual electrical drawings.
Austrian grid connection requirements (TOR compliance)
Austria’s DSOs — Wien Energie, Netz Oberosterreich, EVN, Salzburg Netz — require specific grid connection documentation per TOR (Technische und Organisatorische Regeln) standards set by E-Control. Feed-in tariff administration runs through OeMAG. Incomplete or non-compliant grid documentation leads to rejected applications and project delays.
Bankability and Austrian lender acceptance
Austrian banks (Erste Bank, Raiffeisen, BAWAG, Bank Austria) require bankable energy yield reports for project financing. PVsyst is the gold standard. But SurgePV’s P50/P75/P90 analysis delivers comparable accuracy (within ±3% vs. PVsyst) at lower cost — EUR 633/user/year vs. EUR 2,400+ for PVsyst combined with CAD tools.
EAG grant and subsidy documentation
Austria’s EAG provides investment grants up to EUR 250/kWp, but requires detailed technical and cost documentation. Incomplete grant applications get rejected. On a 100 kWp commercial system, that is EUR 20,000–25,000 in lost subsidies. Software with automated BOM generation and cost reporting streamlines EAG applications significantly.
Commercial rooftop focus
According to PV Austria, the market is dominated by commercial and industrial rooftop installations (40–50% of the market). Residential-focused tools like Aurora struggle with flat industrial roofs, complex shapes, and carport designs. Austrian EPCs need fast commercial layout tools and carport design capabilities.
Workflow efficiency
Austrian installers operate in a competitive market with thin margins (8–12% typical). Platforms requiring AutoCAD or multiple tools slow teams down by 50–70%. Calculate your potential savings with our solar ROI calculator.

Bottom Line: Best Solar Design Software for Austria
For Austrian EPCs and commercial installers: SurgePV offers the most complete platform with automated SLD generation, OVE-compliant electrical engineering, and bankable P50/P90 reports — all without purchasing AutoCAD. Pricing starts at EUR 633/user/year (vs. EUR 6,600+ for Aurora + AutoCAD).
For residential installers with international operations: Aurora Solar provides proven 3D modeling and proposal tools but requires AutoCAD (EUR 1,800/year) for SLDs.
For bankability-critical projects: PVsyst remains the gold standard for financing reports accepted by all Austrian banks.
For utility-scale EPCs (1+ MW): PVCase offers powerful optimization for large solar farms, but AutoCAD dependency makes it unsuitable for small-to-medium installers.
The Austrian solar market is not slowing down. The EPCs winning projects today are the ones delivering OVE-compliant documentation and bankable reports faster than the competition – not spending extra hours in AutoCAD. Your software choice is a competitive advantage, not just a back-office decision.
Which Software Is Right for Your Use Case?
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.
- 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 Austria EPCs, developers, and medium-to-large installers benefit from integrated platforms that reduce manual work and improve accuracy.
Frequently Asked Questions (FAQs)
How accurate is SurgePV’s LIDAR shading in Dutch rooftops like Utrecht or Amsterdam?
SurgePV uses AI-enhanced LIDAR scans at 5–10 cm resolution to detect dormers, chimneys, and steep roof planes typical in Dutch architecture. Shading accuracy is per-panel and time-resolved—validated against PVGIS irradiance data and field measurements.
Does SurgePV calculate real output loss based on shade for Dutch saldering forecasts?
Yes. SurgePV connects shading maps directly to its 8760-hour simulation engine, adjusting P50/P90 forecasts based on seasonal irradiance loss. These results are automatically factored into ROI projections, cash flow forecasts, and payback timeframes under the current saldering regime.
Can I export Dutch-labeled shading visuals for customers or permitting?
Absolutely. All shading reports, ROI summaries, and layout diagrams are available in Dutch and formatted for both residential client use and compliance documents—such as those required by municipalities or financiers.
How does SurgePV’s shade tool compare to Solargraf or Aurora?
SurgePV offers deeper integration: LIDAR + per-panel shading tied to full-year yield modeling, localized in Dutch. Solargraf excels at speed but lacks advanced simulation. Aurora delivers impressive visuals, but requires manual ROI calculations and lacks Dutch regulatory alignment.
What time savings can I expect versus HelioScope or PVsyst shading workflows?
Installers report 50–70% time savings by switching from HelioScope/PVsyst + Excel workflows to SurgePV. The platform replaces three separate tools with one end-to-end environment—from layout to shading to final proposal.
