TL;DR: SurgePV is the strongest all-in-one platform for Tunisia — automated IEC SLDs for STEG grid connection, P50/P90 bankability at ±3% vs PVsyst, North African climate modeling (1,800–2,200 kWh/m²/year), and Saharan dust/soiling loss calculations. PVsyst remains the gold standard for simulation bankability when international financiers require it. HelioScope handles commercial rooftop layouts. Aurora Solar and PVCase are poor fits for most Tunisian EPCs.
Tunisia’s Tunisian Solar Plan targets 4,700 MW of renewable capacity by 2030. That’s more than 6x the current ~700 MW installed base. The pipeline keeps growing — STEG net metering under Law 2015-12, PROSOL subsidies covering up to 30% of residential PV costs, and rising electricity tariffs pushing C&I payback periods down to 4–7 years.
But the vast majority of Tunisian solar installers still design projects using Excel spreadsheets and manual calculations. A 200 kW commercial rooftop in Sfax takes 2–4 hours to design manually. Temperature derating for 45-degree summers gets estimated, not calculated. Saharan dust losses — 5–15% of annual production depending on cleaning schedules — get ignored entirely. And when international lenders like the AfDB or World Bank ask for bankable P50/P90 reports? The installer scrambles for PVsyst access they don’t have.
The right solar design software for Tunisia handles North African irradiance (1,800–2,200 kWh/m²/year GHI), STEG grid compliance documentation, high-temperature performance modeling, and dust/soiling losses — while producing bankable reports that international development financiers accept.

SurgePV — Best End-to-End Solar Platform for Tunisia
About SurgePV
SurgePV is the only cloud-based platform combining AI-powered design, automated electrical engineering, bankable simulations, and professional proposals — without tool-switching.
For Tunisian EPCs juggling STEG grid connection requirements, international lender bankability demands, and the specific challenges of designing in North African heat and dust, SurgePV eliminates the need for AutoCAD, PVsyst validation, and Excel financial models. You design a 500 kW commercial rooftop in Sfax, generate IEC-compliant single line diagrams automatically, run 8760-hour shading analysis calibrated for Tunisian solar geometry, and produce bankable P50/P90 reports — all in the same platform.
Target Users: Commercial EPCs (50 kW–10 MW), Tunisian solar installers (residential and commercial), consultants managing World Bank or AfDB-funded projects, designers needing STEG-ready documentation.
Unique Value for Tunisia: SurgePV is the only platform with integrated SLD generation and wire sizing that eliminates AutoCAD dependency. That saves $2,000/year in licensing costs and removes 2–3 hours of manual electrical drafting per project. For Tunisian EPCs operating in a market where C&I payback periods run 4–7 years and margins stay tight, those savings add up.
Pro Tip
When evaluating solar design software for Tunisia, run a summer stress test first. Model your most complex project at 45-degree ambient temperature with 10% soiling losses. Any platform that handles Tunisian peak summer conditions accurately will handle the rest of the year — but a tool optimized for temperate climates will fall apart under North African heat.
Key Features for Tunisia
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 Tunisian building stock — flat concrete rooftops in Tunis and Sousse, industrial warehouses in Sfax — that automation matters.
The platform handles the array configurations Tunisian EPCs use: south-facing tilted systems (28–34 degrees optimal for Tunisia’s latitude), East-West layouts popular on flat commercial rooftops, and ground-mount tracker configurations for utility-scale projects under the Tunisian Solar Plan. Module layout optimization automatically adjusts spacing based on latitude and shading geometry.
Electrical Engineering (Key for STEG Compliance)
Here’s where SurgePV pulls ahead of every other tool on this list. Single line diagram generation is automated. Complete your design, click generate, and within 5–10 minutes you have an IEC-compliant electrical schematic showing DC arrays, combiners, disconnects, inverters, AC wiring, breakers, and grid interconnection. That SLD is ready for STEG grid connection applications.
The alternative? Export your design to AutoCAD and spend 2–3 hours drafting the SLD manually. That’s what most Tunisian EPCs do today — if they have AutoCAD at all.
Wire sizing calculations happen instantly: DC and AC wire gauges based on current, distance, voltage drop limits (under 2% optimal, 3% maximum), temperature correction factors (critical for Tunisia’s summer heat), and conduit fill adjustments. All IEC compliant.
Simulation and Bankability
International lenders — AfDB, World Bank, KfW, EBRD — require accurate production forecasts before releasing financing for Tunisian solar projects. You cannot show up with an Excel estimate.
SurgePV’s 8760-hour shading analysis models the actual sun path at your specific Tunisian latitude. At 34 degrees N in Tunis, solar geometry differs meaningfully from northern European defaults. At 33 degrees N in Tozeur, near the Saharan edge, irradiance hits 2,200 kWh/m²/year — but only if your tool models local climate data accurately.
Production simulation achieves ±3% accuracy compared to PVsyst — close enough for most Tunisian commercial projects without separate validation. P50 (median expected), P75 (conservative), and P90 (worst-case) estimates give international lenders the metrics they need.
Financial modeling includes Tunisian-specific inputs: STEG tiered tariff structures (TND 0.150–0.350/kWh), PROSOL Elec subsidy calculations (up to 30% capital subsidy for residential), net metering economics under Law 2015-12, and corporate PPA structures for commercial projects.
North African Climate Modeling
Tunisia sits in one of the world’s best solar irradiance zones — 1,800–2,200 kWh/m²/year GHI. But that advantage comes with design challenges that generic tools miss.
Temperature derating is real. When ambient temperatures hit 35–45 degrees C during summer, crystalline silicon modules lose 0.3–0.5% efficiency per degree above 25 degrees C. A tool that ignores temperature coefficients will overpredict Tunisian summer production by 8–12%.
Dust and soiling matter. Saharan dust reduces output by 5–15% depending on location (coastal Tunis versus interior Tozeur) and cleaning frequency. SurgePV models soiling losses so your production estimates reflect real-world Tunisian conditions.

Aurora Solar — Polished Proposals, Limited Tunisia Features
Aurora Solar is a cloud-based platform built primarily for residential solar in the US market. It delivers strong AI-powered roof detection, 3D modeling, and visually polished proposals that impress homeowners.
Key Strengths: Fast roof modeling with LIDAR integration, beautiful customer-facing proposals, CRM integrations for managing sales pipelines. If your Tunisian company focuses on residential installations and values presentation quality, Aurora delivers on aesthetics.
Where Aurora Falls Short for Tunisia: No automated SLD generation. Tunisian EPCs still need AutoCAD ($2,000/year per user) for IEC-compliant electrical documentation and STEG grid connection applications. Limited North African climate optimization — the platform was designed for US latitudes and weather patterns. No native dust/soiling loss modeling for Saharan conditions. No STEG tariff database or PROSOL subsidy calculations. At approximately $3,108/user/year before adding AutoCAD, it is the most expensive option.
Best For: Large Tunisian EPCs with international operations where visual proposal quality matters more than electrical engineering depth.

Did You Know?
Tunisia’s solar irradiance ranges from 1,600–2,000 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).
PVsyst — Bankable Simulation Standard, Not a Design Tool
PVsyst remains the industry standard for solar simulation and bankability reports. International lenders and development financiers routinely require PVsyst validation for project financing approval across North Africa.
Key Strengths: Deep simulation engine with Meteonorm weather data covering Tunisian locations. The most trusted name in bankability — if an AfDB project officer asks for production estimates, they expect PVsyst format. Detailed loss modeling including soiling, mismatch, degradation, and temperature losses that specialized financial models rely on.
Where PVsyst Falls Short for Tunisia: It is not a design platform. No roof modeling, no module layout tools, no electrical engineering. Desktop software requiring Windows installation (no cloud access from project sites). Steep learning curve (6–8 weeks typical). No proposal generation. No SLD generation. And while the ~$1,250 perpetual license seems affordable, you still need design tools and AutoCAD on top.
Best For: Tunisian EPCs who need separate bankability validation for utility-scale projects financed by AfDB, World Bank, or KfW. Many Tunisian teams use PVsyst as a validation check, not their primary design tool.
Read our full PVsyst review for detailed analysis.
HelioScope — Cloud Commercial Design, No Electrical Engineering
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 C&I rooftop design tools for standard projects. Good simulation accuracy for commercial layouts.
Where HelioScope Falls Short for Tunisia: No electrical engineering capabilities (no SLD, wire sizing, or panel schedules). Tunisian EPCs still need AutoCAD for STEG documentation. Limited North African climate optimization — dust/soiling modeling is basic at best. No Tunisian financial modeling (no STEG tariffs, PROSOL subsidies, or TND currency). Pricing at $2,640+/year before adding AutoCAD.
Best For: Tunisian commercial installers handling straightforward rooftop projects who need quick layouts and basic production estimates, with separate tools for electrical compliance.
Read our full HelioScope review for detailed analysis.
PVCase — CAD-Based Utility-Scale, Overkill for Most Tunisian Projects
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 Tunisia: Requires AutoCAD ($2,000/year per user) plus PVCase licensing. Desktop-only (no cloud access). Steep learning curve (6–8 weeks minimum). Overkill for residential and small commercial projects (under 1 MW). No built-in proposal generation. No integrated financial modeling for Tunisian economics. Tunisia’s market currently splits 40% C&I rooftop, 35% utility-scale, 25% residential — PVCase targets only the utility-scale segment.
Best For: Tunisian EPCs with dedicated CAD engineers working on utility-scale ground-mount projects (10 MW+) under the Tunisian Solar Plan where terrain analysis and cable routing optimization justify the cost and complexity.

What Makes the Best Solar Design Software for Tunisia
Choosing solar software for Tunisia is different from choosing software for Germany or the United States. Five factors determine whether a platform actually works for North African conditions:
1. North African Climate Accuracy (Most Critical)
Tunisia receives 1,800–2,200 kWh/m²/year GHI — among the highest in the Mediterranean. But that high irradiance comes with summer temperatures reaching 35–45 degrees C, which reduce crystalline silicon module output by 8–12% compared to Standard Test Conditions. Design software that uses STC ratings without temperature correction will overpredict Tunisian production every time. Saharan dust adds 5–15% soiling losses depending on location and cleaning schedules. Your software needs to model both effects accurately.
2. STEG Grid Compliance
All grid-connected solar installations in Tunisia require documentation per STEG standards. Net metering under Law 2015-12 allows self-consumption with grid credits, but STEG requires technical documentation including single line diagrams, protection device specifications, and grid interconnection details for approval. Software that can’t generate these documents forces you back to AutoCAD.
3. Bankability for International Lenders
Tunisia’s solar pipeline depends on international development finance. The AfDB, World Bank, KfW, and EBRD fund projects across the country. These institutions require bankable production forecasts with P50/P90 estimates before releasing capital. Software producing only basic energy estimates won’t satisfy lender due diligence for projects above 5 MW.
4. Financial Modeling with Tunisian Economics
Tunisian solar economics include STEG tiered tariffs (TND 0.150–0.350/kWh), PROSOL Elec subsidies (up to 30% capital subsidy for residential PV), net metering credits under Law 2015-12, and feed-in tariffs under Decree 2016-1123 for larger projects. Software that can model these inputs gives Tunisian EPCs accurate payback calculations.
5. Workflow Efficiency
The typical Tunisian EPC workflow today: design in HelioScope or manual tools, export to AutoCAD for electrical documentation, run PVsyst for bankability, build proposals in Excel. Four tools, 3–4 hours per project, version control headaches. The right software consolidates this into a single workflow.
Tunisia Solar Market Context
Tunisia’s solar market is growing at 20–30% annually, driven by the Tunisian Solar Plan targeting 4,700 MW of renewable capacity by 2030. From a ~700 MW installed base, the country is accelerating deployment through multiple mechanisms: STEG net metering (Law 2015-12), PROSOL residential subsidies, corporate PPAs, and international development financing.
The market splits roughly 40% commercial/industrial, 35% utility-scale, and 25% residential. C&I rooftop dominance means most Tunisian EPC solar software focus needs to be on 50 kW–5 MW systems, not residential-only tools.
Key challenges for Tunisian installers include high summer temperatures requiring accurate performance derating, Saharan dust impacts on production, STEG’s specific grid connection requirements, and the need for bankable documentation to access international financing. The installer landscape includes 200–400 registered solar companies, with STEG Energies Renouvelables (SER) leading utility-scale and a mix of local and international firms handling C&I and residential.
| 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 tier) |
| Utility-scale developer (>1 MW) in Tunisia | 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 big marketing budget, Aurora’s proposals are unmatched — but expensive.
How We Tested and Ranked These Tools
We evaluated 5 solar design platforms against Tunisian market requirements using weighted criteria.
Testing Methodology:
- Hands-on testing with Tunisian EPC teams in Tunis, Sfax, and Sousse
- Designed identical 200 kW commercial rooftop projects across all 5 platforms
- Validated production estimates against Tunisian climate data and existing system performance
- Tested STEG electrical documentation output quality
- Benchmarked dust/soiling loss modeling accuracy
- Testing period: October 2025 through January 2026
| Criteria | Weight | What We Tested |
|---|---|---|
| Design Accuracy for Tunisian Conditions | 25% | Temperature derating, dust losses, GHI modeling |
| Bankability and Lender Acceptance | 25% | P50/P90 vs actual, AfDB/World Bank acceptance |
| STEG Grid Compliance | 20% | SLD quality, grid documentation |
| Financial Modeling | 15% | STEG tariffs, PROSOL, TND currency |
| Workflow Efficiency | 10% | Design-to-proposal speed |
| Pricing and Value | 5% | TCO for 3-user Tunisian team |
Scoring: Each platform scored 1–10 on each criterion. SurgePV scored highest overall (8.7/10), followed by PVsyst (7.4 for simulation accuracy), Aurora (6.5), HelioScope (6.2), and PVCase (5.8 due to cost and limited applicability).
Bottom Line: Best Solar Design Software for Tunisia
Most Tunisian EPCs today juggle 3–4 solar design software tools: Aurora or HelioScope for design, AutoCAD for electrical documentation, PVsyst for bankability validation, and Excel for financial modeling. This tool-switching wastes 2–3 hours per project, introduces data transfer errors, and costs $16,000+ annually for a 3-person team.
With SurgePV, Tunisian EPCs complete design, IEC-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 STEG submission.
Our Recommendations:
- For C&I EPCs in Tunisia: SurgePV. The combination of North African climate optimization, automated SLD generation, and bankable simulations at $4,497/year (3 users) beats the ~$16,900/year cost of Aurora + AutoCAD + PVsyst.
- For residential installers: SurgePV for engineering depth and PROSOL subsidy calculations, or Aurora if visual proposal quality matters more than electrical compliance.
- For bankability validation only: PVsyst remains the gold standard that international lenders trust. Use it alongside SurgePV for large project financing.
- For utility-scale (10 MW+): PVCase if you have CAD expertise and the budget. SurgePV handles everything under 10 MW.
