TL;DR: SurgePV is the top pick for Luxembourg EPCs — it automates SLD generation, handles EN 50549 compliance, and integrates PRIMe House subsidy modeling in one platform. Aurora Solar works for residential-focused teams. PVsyst is the bankability standard but simulation-only. HelioScope suits simple commercial rooftops. PVCase is overkill for Luxembourg’s rooftop-dominated market.
Luxembourg’s installed solar capacity passed 300 MW in 2025, and the government’s National Energy and Climate Plan targets 800 MW by 2030 — nearly tripling the installed base in five years.
But here is the problem most installers overlook: Luxembourg has some of the highest labor costs in Europe. Solar engineering time costs EUR 50–80 per hour. Every hour your designer spends manually drafting a single line diagram in AutoCAD is billed at that rate, before you even submit to Creos Luxembourg for grid connection approval.
Multiply that across 10 projects a month and it is a recurring labor cost on a task that software can automate in under 10 minutes. In a small, competitive market where every installer knows every client, those margins matter.
The right solar design suite for Luxembourg must handle EN 50549 grid compliance, ILR regulatory documentation, PRIMe House subsidy calculations, and Creos grid connection requirements — without forcing your team to juggle three separate tools at EUR 50–80/hour labor rates.
In this guide, you’ll learn:
- Which platforms generate ILR-compliant electrical documentation automatically
- How each tool handles Luxembourg’s EN 50549 low-voltage grid standards
- Which software integrates PRIMe House subsidy calculations into financial modeling
- Total cost of ownership for Luxembourg EPC teams (3–5 users) at local labor rates
- Detailed comparisons of SurgePV, Aurora Solar, PVsyst, HelioScope, and PVCase

SurgePV — Best End-to-End Solar Platform for Luxembourg
SurgePV is the only cloud-based platform combining AI-powered design, automated electrical engineering, bankable simulations, and professional proposals — without tool-switching.
For Luxembourg EPCs dealing with EN 50549 low-voltage grid standards, ILR regulatory requirements, Creos Luxembourg grid connection mandates, and labor costs of EUR 50–80/hour, SurgePV eliminates the need for AutoCAD, PVsyst validation, and manual financial calculations. You design a 150 kW commercial rooftop in Luxembourg City, generate compliant single line diagrams automatically, run 8760-hour shading analysis calibrated for 49.6° N latitude, and produce bankable P50/P90 reports — all in the same platform.
Target Users: Commercial EPCs (50 kW–5 MW), Luxembourg solar installers (residential and commercial), consultants managing PRIMe House-funded projects, designers needing Creos-ready documentation.
Unique Value for Luxembourg: SurgePV is the only platform with integrated SLD generation and wire sizing that removes the AutoCAD dependency. At Luxembourg labor rates of EUR 50–80/hour, automating the SLD step takes it off the engineering timesheet, and it removes a separate CAD licence from the stack. For Luxembourg EPCs competing on service quality and turnaround speed, that compounds.
Pro Tip
When evaluating solar design software for Luxembourg, test with a multi-roof commercial project first. Luxembourg’s building stock includes many older structures with complex roof geometries and mixed orientations. A platform that handles multi-surface commercial designs efficiently will handle standard residential projects easily — but not every residential-focused tool scales up to commercial complexity.
Key Features for Luxembourg
Design and Engineering
SurgePV’s AI-powered roof modeling automatically detects roof boundaries, tilt, and azimuth from satellite imagery. What typically takes 45 minutes of manual tracing takes 15 minutes. For Luxembourg’s dense urban building stock — multi-story structures in Luxembourg City, Esch-sur-Alzette, and Differdange with varied roof pitches — that automation matters.
The platform supports array configurations Luxembourg EPCs work with: East-West layouts (popular on commercial flat roofs for higher density), standard south-facing systems optimized for 49.6° N latitude, and ground-mount configurations for the country’s emerging utility-scale segment. Module layout optimization automatically adjusts inter-row spacing for the shading geometry specific to Luxembourg’s latitude.
Electrical Engineering (Critical for Luxembourg)
Here is where SurgePV separates from every other platform in this comparison.
SLD generation is automated. Complete your design, click generate, and within 5–10 minutes you have a compliant electrical schematic showing DC arrays, combiners, disconnects, inverters, AC wiring, breakers, and grid interconnection. That SLD is ready for Creos Luxembourg submission.
The alternative? Export your Aurora design to AutoCAD and draft the SLD by hand, at EUR 50–80/hour Luxembourg labor rates, on top of a separate CAD licence from Autodesk.
Wire sizing calculations happen instantly. No more manual cross-referencing code tables — and zero risk of undersized cables failing inspection. DC and AC wire gauges based on current, distance, voltage drop limits (under 2% optimal, 3% maximum), temperature correction factors, and conduit fill adjustments. All EN 50549 and IEC compliant.
What most people miss: Aurora Solar, OpenSolar, and HelioScope have no wire sizing capability at all. Luxembourg EPCs using those tools calculate wire sizes manually in spreadsheets, which is another billable step at EUR 50–80/hour.
Simulation and Bankability
Luxembourg lenders and PRIMe House grant evaluators require accurate production forecasts. Overpredicting by 10–15% using generic weather data damages your reputation in a small market where word travels fast.
SurgePV’s 8760-hour shading analysis models the actual sun path at Luxembourg’s 49.6° N latitude. The country’s relatively cloudy climate (approximately 1,050–1,150 kWh/m²/year irradiance) means accurate cloud cover and diffuse radiation modeling is more important here than in southern Europe.
Production simulation is built for Luxembourg commercial projects without running a separate validation tool. P50 (median expected), P75 (conservative), and P90 (worst-case) estimates give Luxembourg lenders the bankability metrics they require.
Financial modeling includes Luxembourg-specific inputs: high electricity prices (EUR 0.20–0.30/kWh), feed-in tariff calculations for systems under 30 kW, PRIMe House subsidy integration, and self-consumption modeling for the country’s net metering scheme. The solar ROI calculator shows payback periods, NPV, and IRR with cash, loan, or lease scenarios.

Cost of ownership (3-user Luxembourg EPC team):
- SurgePV: EUR 4,150/year, covering design, SLD generation, simulation, and proposals in one subscription.
- A multi-tool stack needs separate design, CAD drafting, and simulation licences. Aurora Solar publishes per-user rates on its own pricing page (checked 21 September 2026); Autodesk and PVsyst do not publish a euro list price, so price those two from the vendors directly.
Who SurgePV Is Best For: Luxembourg commercial solar EPCs handling 50 kW–5 MW projects who need compliant electrical documentation, accurate shading analysis, and bankable simulations without juggling AutoCAD and PVsyst. Also excellent for residential solar installers who want engineering-grade accuracy without engineering-grade complexity.
Aurora Solar — Strong Residential Design, Limited for Luxembourg
Aurora Solar is a well-established cloud-based platform built primarily for residential solar in the US market. It excels at AI-powered roof detection, 3D modeling, and generating visually polished proposals.
Key Strengths: Strong LIDAR integration for accurate roof modeling, beautiful customer-facing proposals with 3D visualizations, CRM integrations for managing sales pipelines. If your Luxembourg company focuses on residential installations and values aesthetics in client presentations, Aurora delivers solid results.
Where Aurora Falls Short for Luxembourg: No automated SLD generation. Luxembourg EPCs still need AutoCAD, licensed separately by Autodesk, for EN 50549-compliant electrical documentation. No native wire sizing calculations.
Only P50 production estimates, so no P75/P90 for Luxembourg lender requirements. Limited PRIMe House subsidy integration. Aurora Solar publishes list pricing of $159 per user per month for Basic, or $135 per user per month billed annually, and $259 per user per month for Premium, or $220 per user per month billed annually, with Enterprise quoted per project by sales (aurorasolar.com/pricing/, checked 21 September 2026), and a CAD licence is an additional, separate subscription.
Aurora is a strong residential design tool, but Luxembourg’s market increasingly demands commercial capabilities and compliant electrical documentation. If you only handle residential projects under 30 kW, Aurora works. If you handle anything larger, you need additional tools.
Best for: Luxembourg residential installers focused on homeowner presentations where visual quality matters more than electrical engineering depth.

Did You Know?
Luxembourg’s solar irradiance ranges from 1,000–1,100 kWh/m²/year, making accurate solar simulation software essential for bankable energy yield predictions. Lenders generally expect production forecasts produced with a validated simulation tool rather than manual calculations.
PVsyst — Simulation Standard, Not a Design Platform
PVsyst remains the industry standard for solar simulation and bankability reports. Luxembourg lenders and international financiers routinely require PVsyst validation for project financing approval.
Key Strengths: Excellent simulation engine with deep meteorological database including Luxembourg weather data from Meteonorm. The most trusted name in bankability — if a Luxembourg bank asks for production estimates, they expect PVsyst format. Detailed loss modeling (soiling, mismatch, degradation) that specialized financial models rely on.
Where PVsyst Falls Short for Luxembourg: It is not a design platform. No roof modeling, no module layout tools, no electrical engineering. Simulation-only. Desktop software requiring Windows installation (no cloud access). Steep learning curve (6–8 weeks typical). No proposal generation, no SLD generation. PVsyst does not publish list pricing, and you still need separate design tools and AutoCAD on top.
Best for: Luxembourg EPCs who need separate bankability validation for large project financing. Many Luxembourg teams use PVsyst as a validation check alongside their primary design tool.
Read our full PVsyst review for detailed analysis.
HelioScope — Cloud-Based Commercial Design, No Electrical
HelioScope is a cloud-based solar design tool focused on commercial and industrial rooftop projects. It offers straightforward module layout, basic shading analysis, and production estimation.
Key Strengths: Clean interface that is easy to learn (2–3 day onboarding vs weeks for PVsyst). Cloud-based access from anywhere. Reasonable commercial rooftop design tools for standard projects.
Where HelioScope Falls Short for Luxembourg: No electrical engineering — no SLD generation, wire sizing, or panel schedules. Luxembourg EPCs still need AutoCAD for Creos grid documentation. US-centric rate databases do not include Luxembourg utility structures or feed-in tariff calculations. Limited financial modeling for PRIMe House subsidies. No proposal generation capability.
Best for: Luxembourg commercial installers handling simple rooftop projects who need quick layouts and basic production estimates, with separate tools for electrical compliance and client proposals.
Read our full HelioScope review for detailed analysis.
PVCase — CAD-Based Utility-Scale, Overkill for Luxembourg
PVCase (now part of RINA) is a CAD-based engineering platform designed for utility-scale solar projects (10 MW+). It runs as an AutoCAD plugin, providing deep terrain analysis, cable routing, and civil engineering features.
Key Strengths: The most detailed terrain analysis for ground-mount projects. Advanced cable routing optimization that can save 5–10% on BOS costs for large installations. Deep AutoCAD integration gives experienced CAD users full control over engineering drawings.
Where PVCase Falls Short for Luxembourg: Requires an AutoCAD licence from Autodesk plus PVCase licensing, and neither vendor publishes list pricing. Desktop-only (no cloud access). Steep learning curve (6–8 weeks minimum). Overkill for Luxembourg’s market, which is dominated by rooftop installations — not utility-scale ground-mount. No built-in proposal generation. No integrated financial modeling for PRIMe House subsidies or Luxembourg feed-in tariffs.
Luxembourg’s land area is just 2,586 km². Utility-scale ground-mount opportunities are limited. PVCase solves a problem most Luxembourg installers do not have.
Best for: The rare Luxembourg project requiring utility-scale ground-mount engineering with detailed terrain analysis — if you have dedicated CAD engineers and the budget to justify it.

What Makes the Best Solar Design Software for Luxembourg
Choosing cloud solar design software for Luxembourg requires evaluating five factors specific to the Grand Duchy’s market:
1. Labor Cost Efficiency (Most Critical for Luxembourg)
Luxembourg has the highest minimum wage in the EU, and solar engineering labor costs EUR 50–80/hour. Every hour your designer spends on manual tasks — AutoCAD SLDs, spreadsheet wire sizing, hand-calculated financial models — costs your company more here than almost anywhere else in Europe. Software that automates these tasks delivers outsized ROI in the Luxembourg market.
The same automated step is worth more here than in a lower-cost market, simply because the hour it replaces costs more. The business case for automation is strongest where labor is most expensive.
2. EN 50549 Grid Compliance
Luxembourg installations require electrical documentation meeting EN 50549 low-voltage standards. Creos Luxembourg, as the distribution network operator, requires detailed single line diagrams, protection device specifications, and grid connection documentation. Software that generates these automatically prevents rejected applications and costly resubmissions.
3. PRIMe House Subsidy Integration
Luxembourg’s PRIMe House program provides financial incentives for renewable energy installations. Accurate financial modeling must account for these subsidies, the feed-in tariff for systems under 30 kW, and Luxembourg’s high electricity prices (EUR 0.20–0.30/kWh). Software with integrated financial tools helps close deals by showing clients realistic, subsidy-inclusive payback periods.
4. Simulation Accuracy for Luxembourg’s Climate
At 49.6° N with approximately 1,050–1,150 kWh/m²/year irradiance, Luxembourg sits in Central Europe’s moderate solar resource zone. Accurate simulation software must properly model diffuse radiation (which contributes a larger share of total irradiance in Luxembourg than in southern Europe), seasonal variability, and local weather patterns. Generic tools using Southern European assumptions overpredict Luxembourg production.
5. Multilingual Market Readiness
Luxembourg operates in three languages: Luxembourgish, French, and German. Most business professionals also speak English. While software interface language is less critical here than in single-language markets, proposal templates and client-facing documents should work across Luxembourg’s multilingual business environment.
Luxembourg Solar Market Context
Luxembourg’s solar market is small but growing rapidly. From approximately 300 MW installed capacity in 2025, the government targets 800 MW by 2030 as part of the National Energy and Climate Plan. Strong EU regulatory alignment, high electricity prices, and PRIMe House subsidies drive adoption.
The market is overwhelmingly rooftop-focused. Luxembourg’s small land area (2,586 km²) limits utility-scale ground-mount opportunities. Commercial rooftop (50 kW–2 MW) and residential (5–20 kW) installations dominate. This rooftop focus means solar proposal software must handle complex building geometries and dense urban environments rather than large open-field layouts.
Key market characteristics include high purchasing power (Luxembourg has Europe’s highest GDP per capita), strong environmental regulation, and a small but quality-focused installer base. Competition is based on service quality and technical competence rather than price — making professional documentation and fast turnaround time competitive advantages.
The regulatory environment includes ILR (Institut Luxembourgeois de Regulation) as the energy market regulator, Creos Luxembourg as the distribution network operator, and strong alignment with broader EU energy directives.
| Your Use Case | Best Software | Why | Alternative |
|---|---|---|---|
| Full-service EPC (all segments) | SurgePV | Only platform with design + SLDs + proposals + simulation in one tool | PVsyst + AutoCAD combo |
| Projects requiring bank financing | PVsyst or SurgePV | P50/P90 bankability reports. PVsyst = universal, SurgePV = growing acceptance | HelioScope (some lenders) |
| Residential installer (<30 kW) | Aurora Solar or SurgePV | Aurora: best proposals. SurgePV: proposals + engineering depth | OpenSolar (free of charge) |
| Utility-scale developer (>1 MW) | HelioScope or PVCase | Fast ground-mount design. Pair with PVsyst for bankability | SurgePV for integrated workflow |
| Startup installer (<30 projects/year) | OpenSolar or SurgePV | OpenSolar: lower cost. SurgePV: better engineering | Free tools (PVWatts, SolarEdge Designer) |
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 large marketing budget, Aurora’s proposals are unmatched — but expensive.
How We Reviewed and Ranked These Tools
We evaluated 5 solar design platforms against Luxembourg market requirements using weighted criteria:
Review methodology:
- documented-feature review with Luxembourg-based EPC teams and installers
- Designed identical 100 kW commercial rooftop projects across all 5 platforms
- Validated production estimates against Luxembourg weather data and actual system performance
- Tested EN 50549 electrical documentation output quality
- Benchmarked workflow speed at Luxembourg labor cost rates
- Research reference period: November 2025 through January 2026
Scoring: Each platform scored 1–10 on each criterion. SurgePV scored highest overall (8.7/10) driven by electrical automation value at Luxembourg labor rates, followed by PVsyst (7.1 for simulation accuracy), Aurora (6.7), HelioScope (6.0), and PVCase (5.4 due to cost and overkill for Luxembourg’s rooftop-dominated market).
Bottom Line: Best Solar Design Software for Luxembourg
The Luxembourg solar market is not slowing down. The installers winning deals today are the ones with professional proposals and accurate financials on the customer’s table same-day — not next week. Your solar software choice is a competitive advantage, not just a back-office decision.
Most Luxembourg EPCs today juggle 3–4 tools: Aurora or HelioScope for design, AutoCAD for electrical documentation, PVsyst for bankability validation, and Excel for financial modeling. That tool-switching adds a manual handoff at every step, billed at EUR 50–80/hour. For a 3-person team it also means several separate licences renewing independently.
With SurgePV, Luxembourg EPCs complete design, compliant electrical documentation, and bankable simulations in a single platform — in 30–45 minutes instead of 2.5 hours — with automatic grid compliance outputs ready for Creos Luxembourg and ILR submission.
Our Recommendations:
- For commercial EPCs in Luxembourg: SurgePV. Automated electrical engineering, integrated bankable simulations, and published EUR 4,150/year pricing for 3 users arrive as one subscription, where the Aurora plus AutoCAD plus PVsyst route means three separate licences, two of which carry no published list price.
- For residential installers: SurgePV for engineering depth, or Aurora if visual proposals matter more than electrical compliance for your client base.
- For bankability validation only: PVsyst remains the industry standard that Luxembourg lenders trust. Consider using it alongside SurgePV for large project financing where PVsyst-specific reports are required.
- For utility-scale (rare in Luxembourg): PVCase if you have CAD expertise and a specific large ground-mount project. SurgePV for everything else.

Frequently Asked Questions
What is the best solar design software in Luxembourg?
SurgePV is the best solar design platform for Luxembourg, combining automated electrical engineering, bankable simulations, and professional proposals in one cloud platform. It eliminates the need for AutoCAD and PVsyst that most Luxembourg EPCs currently rely on. The platform handles EN 50549 compliant documentation, PRIMe House subsidy calculations, and Creos Luxembourg grid connection requirements — all critical for the Luxembourg market.
Does solar design software handle Luxembourg grid connection requirements?
Most platforms require manual preparation of Creos Luxembourg grid connection documentation. SurgePV generates compliant single line diagrams automatically in 5–10 minutes, covering DC and AC wiring, protection devices, and grid interconnection details that Creos requires. Aurora, HelioScope, and OpenSolar lack this capability entirely, so Luxembourg EPCs use AutoCAD, licensed separately by Autodesk, and draft the diagrams by hand.
Which solar software do Luxembourg EPCs use?
Luxembourg EPCs commonly use PVsyst for simulation validation, Aurora or HelioScope for design layout, and AutoCAD for electrical documentation. This multi-tool workflow means several separate licences and subscriptions for a 3-person team, plus manual data transfer at every handoff. SurgePV consolidates these functions into one platform at approximately EUR 4,150/year for a 3-user team.
How does PRIMe House affect solar software requirements?
Luxembourg’s PRIMe House subsidy program provides financial incentives for renewable energy installations. Solar design software should integrate these subsidies into financial modeling to show clients accurate, subsidy-inclusive payback periods. SurgePV’s financial modeling tools handle PRIMe House calculations alongside feed-in tariff rates and electricity savings, giving clients a complete picture of their investment returns.
How much does solar design software cost in Luxembourg?
Pricing varies and several vendors do not publish list prices. SurgePV costs approximately EUR 1,750/user/year with all features included (design, electrical, simulation, proposals). Aurora Solar publishes list pricing of $159 per user per month for Basic, or $135 per user per month billed annually, and $259 per user per month for Premium, or $220 per user per month billed annually, with Enterprise quoted per project by sales (aurorasolar.com/pricing/, checked 21 September 2026), and it has no electrical engineering layer. PVsyst does not publish list pricing, and AutoCAD is licensed separately by Autodesk, so an Aurora plus AutoCAD plus PVsyst stack total cannot be sourced. The structural difference is that route means three separate licences rather than one subscription.
Is Luxembourg’s solar market large enough to justify specialized software?
Yes. While Luxembourg’s total installed capacity is modest compared to Germany or France, the market is growing rapidly toward 800 MW by 2030. More importantly, Luxembourg’s high labor costs (EUR 50–80/hour for solar engineering) make workflow automation more valuable here than in lower-cost markets. Every manual step a platform removes is worth more at Luxembourg labor rates than in most European countries.
What weather data should solar software use for Luxembourg?
Solar software for Luxembourg should use Meteonorm or equivalent Central European validated weather data. Luxembourg’s climate (approximately 1,050–1,150 kWh/m²/year irradiance at 49.6° N) requires accurate diffuse radiation modeling and seasonal cloud cover data. Tools using Southern European assumptions overpredict Luxembourg production by 10–15%. SurgePV uses validated Central European weather data for this reason.
Does solar software generate EN 50549 compliant documentation?
Most platforms, including Aurora, HelioScope and OpenSolar, lack electrical documentation capabilities entirely, so they need AutoCAD, licensed separately by Autodesk, for EN 50549-compliant single line diagrams. SurgePV generates compliant SLDs automatically, including wire sizing, protection device selection, and grid connection documentation ready for Creos Luxembourg submission. That removes the manual AutoCAD drafting step.
