Vietnam went from near-zero solar capacity to 16.5 GW installed between 2017 and 2021 — one of the fastest solar build-outs anywhere in the world, driven by generous feed-in tariffs that attracted massive investment.
Then the FiT expired. The rooftop solar boom-bust cycle left thousands of EPCs scrambling. But the market has not disappeared. It has shifted.
Vietnam’s industrial and commercial (C&I) sector is driving the next wave. Foreign manufacturers (Samsung, Intel, LG) face ESG mandates from international buyers requiring renewable energy sourcing. The new Direct Power Purchase Agreement (DPPA) mechanism enables large consumers to buy solar directly. MOIT policies are evolving to support self-consumption models. And Vietnam’s solar irradiance — 1,400–1,900 kWh/m²/year with the southern provinces receiving the highest values — makes the economics work without subsidies.
But here is the challenge Vietnamese EPCs face daily.
EVN (Vietnam Electricity) requires detailed technical documentation for grid interconnection. Single line diagrams with protection devices, earthing, anti-islanding compliance, and metering configurations. Submit incomplete documentation, and your project approval stalls. For C&I rooftop solar — factory rooftops in Binh Duong, industrial parks in Dong Nai, manufacturing zones in Hai Phong — the electrical documentation requirements are strict. And if you are designing for typhoon-prone central Vietnam (Da Nang, Nha Trang), structural loading calculations must account for 150–200 km/h wind speeds.
The right solar PV design software for Vietnam must generate EVN-compliant electrical documentation, model tropical performance accurately, handle C&I financial modeling with DPPA and self-consumption analysis, and work for teams managing projects from Hanoi to Ho Chi Minh City.
TL;DR — SurgePV is the top pick for Vietnamese C&I EPCs: automated EVN-compliant SLD generation, tropical climate simulation, DPPA financial modeling, and professional proposals in one platform at $1,899 per user per year on the individual plan. PVsyst remains the gold standard for bankable utility-scale simulation. Aurora Solar suits high-volume residential in HCMC and Hanoi.

SurgePV — Best End-to-End Solar Platform for Vietnam
About SurgePV
SurgePV is the only cloud-based platform combining AI-powered design, automated electrical engineering, bankable simulations, and professional proposals without requiring AutoCAD, PVsyst, or any external tools.
For Vietnamese EPCs managing the complexity of EVN grid interconnection, evolving MOIT regulations, and the C&I solar market shift from FiT to self-consumption and DPPA models, SurgePV eliminates the multi-tool workflow that slows projects. Design a 2 MW factory rooftop in Binh Duong, generate EVN-compliant single line diagrams automatically, run 8760-hour shading analysis calibrated for tropical irradiance, and produce bankable P50/P90 reports — all in one platform.
Target Users: C&I EPCs (50 kW–10 MW), solar installers (rooftop and ground-mount), utility-scale developers, consultants preparing feasibility studies for Vietnamese and international lenders.
Unique Value for Vietnam: SurgePV generates EVN-compliant SLDs automatically in 5–10 minutes, cutting the documentation bottleneck that delays grid connection approvals. For EPCs managing the post-FiT shift to C&I self-consumption projects, SurgePV’s financial modeling handles DPPA scenarios, self-consumption optimization, and net metering economics — the analysis clients need before signing contracts.
Pro Tip
When designing solar for Vietnamese factories, always model self-consumption ratios accurately. Under current regulations, maximizing direct consumption (rather than exporting to EVN) delivers the strongest financial returns. Software that models hourly load profiles against production curves helps optimize system sizing for maximum savings.
Key Features for Vietnam
Design and Engineering
SurgePV’s AI-powered roof modeling detects roof boundaries, tilt, and azimuth from satellite imagery in 15 minutes instead of 45 minutes manual. For Vietnamese industrial buildings — the large metal-roofed factories in Binh Duong, Dong Nai, and Long An industrial parks — the automation handles complex rooftop obstacles accurately.
The platform supports all project types Vietnamese EPCs encounter: factory rooftop systems (the dominant C&I segment), ground-mount arrays for utility-scale projects, carport canopies for commercial developments, and tracker configurations. Native carport solar design is unique to SurgePV — no other platform offers built-in carport engineering.
Electrical Engineering (Critical for EVN Approval)
This is the feature that matters most for Vietnamese EPCs.
SLD generation is fully automated. Complete your design, generate the SLD, and in 5–10 minutes you have documentation showing DC arrays, combiners, disconnects, inverters, AC wiring, breakers, protection devices, earthing, and grid interconnection. The SLD meets IEC standards that EVN requires for grid connection approval.
Wire sizing calculations happen instantly — DC and AC wire gauges based on current, distance, voltage drop (under 2% optimal, 3% maximum), and temperature correction for Vietnam’s sustained 30–35°C ambient conditions. Protection device sizing and conduit fill calculations follow IEC standards adopted by Vietnam.
The alternative: export designs to AutoCAD and manually draft the SLD in 2–3 hours. That is where most EVN application errors originate.
Note
Vietnam’s electrical standards are based on IEC codes. SurgePV’s automated SLD generation produces IEC-compliant documentation that meets EVN’s grid connection requirements. Some formatting adjustments may be needed for specific EVN regional templates.
Simulation and Bankability
Vietnamese lenders and international DFIs (ADB, World Bank, IFC, JICA) require credible production estimates for project financing.
SurgePV’s production simulation models tropical climate effects specific to Vietnam: temperature derating at 30–35°C sustained ambient, humidity impact (70–90% RH), soiling losses from industrial dust and monsoon rainfall patterns, and regional irradiance variations — southern provinces (1,700–1,900 kWh/m²/year) receive significantly more sunlight than the north (1,400–1,600 kWh/m²/year).
P50/P90 bankability reports come out of the same model as the design. For C&I projects seeking financing, that is the kind of report Vietnamese and international lenders expect.
C&I Financial Modeling
SurgePV’s financial modeling handles Vietnam’s evolving regulatory environment:
- Self-consumption analysis: Hourly production vs load profile matching for factory operations
- DPPA modeling: Direct Power Purchase Agreement financial scenarios for large consumers
- Net metering economics: Where applicable under current MOIT regulations
- Tariff analysis: EVN commercial and industrial electricity rates
- ROI calculations: Payback, NPV, and IRR via the solar ROI calculator
Here is what this looks like in practice.
Pros and Cons

- For 5 Users Plan: $1,299/user/year (~32.5M VND/user/year) — best value for scaling EPCs
- Includes: All features — design, SLD, simulation, proposals, financial modeling
- No AutoCAD required: removes the separate Autodesk seat an Aurora plus AutoCAD workflow needs
Total Cost of Ownership (3-user Vietnamese EPC team):
- SurgePV: $1,899 per user per year on the individual plan, everything included, one subscription
- Aurora + AutoCAD + PVsyst: three separate per-seat subscriptions. Aurora publishes list pricing (aurorasolar.com/pricing, checked 21 September 2026); AutoCAD and PVsyst are priced on their own vendor sites, and none of the three publish a Vietnam price list.
- SurgePV replaces all three line items with one subscription
Who SurgePV Is Best For: Vietnamese C&I EPCs handling factory rooftop projects (50 kW–10 MW) who need EVN-compliant documentation, tropical simulation accuracy, and professional proposals.

What Makes the Best Solar Design Software for Vietnam
Vietnam’s market conditions create specific all-in-one solar software requirements:
1. EVN Grid Connection Compliance (Most Critical)
EVN interconnection documentation is the primary bottleneck for Vietnamese solar projects. Software must generate IEC-compliant SLDs showing protection devices, earthing, metering points, and anti-islanding compliance. Automated SLD generation reduces the submission errors that cause approval delays of 2–4 weeks.
2. Tropical Climate Modeling
Vietnam spans 8–23 degrees north, with significant regional variation. Southern provinces (HCMC, Binh Duong) receive 1,700–1,900 kWh/m²/year, while northern provinces (Hanoi, Hai Phong) receive 1,400–1,600 kWh/m²/year. Sustained temperatures of 30–35°C, humidity of 70–90%, and monsoon rainfall patterns all affect production. Modeling that accounts for these conditions avoids the over-estimation that generic weather assumptions introduce.
3. C&I Self-Consumption Financial Modeling
Vietnam’s post-FiT market centers on self-consumption. Software must model hourly load profiles against solar production, calculate self-consumption ratios, analyze EVN tariff savings, and handle DPPA financial scenarios. This is not optional — it is how C&I deals are closed.
4. Typhoon Resilience Awareness
Central Vietnam (Da Nang to Nha Trang) experiences typhoons with 150–200 km/h wind speeds. While structural engineering is the EPC’s responsibility, design software should account for wind loading in system layout and support conservative design choices for typhoon-prone regions.
5. Bankability for Vietnamese and International Lenders
Vietnamese banks and international DFIs require bankable P50/P90 analysis. For the growing DPPA market where international manufacturers need certified renewable energy, simulation credibility directly affects contract negotiations.
Vietnam Solar Market Context
Vietnam’s solar market has entered a new phase. After the explosive FiT-driven growth (16.5 GW installed by 2021), the market is transitioning to sustainable, subsidy-free models.
Current Market Drivers:
- C&I self-consumption: Foreign manufacturers (Samsung, Intel, LG) requiring renewable energy for ESG compliance and supply chain requirements
- DPPA mechanism: Enabling direct solar procurement for large consumers (above 1 MW)
- High industrial electricity tariffs from EVN making rooftop solar economically compelling
- Corporate sustainability commitments from international brands with Vietnam operations
- ADB, World Bank, and JICA financing programmes supporting clean energy transition
Market Structure:
- C&I rooftop: 70%+ of current market activity (factory rooftops in industrial parks)
- Utility-scale: Regulated through competitive auctions, evolving policy framework
- Residential: Growing in urban areas (HCMC, Hanoi, Da Nang)
- Floating solar: Emerging opportunity on Vietnam’s reservoirs
Key Challenges:
- Evolving regulatory framework (MOIT policies still developing post-FiT)
- EVN grid capacity constraints in some regions
- Rooftop solar inspection and compliance requirements
- Currency considerations for international equipment procurement
Major solar markets span Ho Chi Minh City/Binh Duong/Dong Nai (southern industrial), Hanoi/Hai Phong (northern industrial), and Da Nang/Nha Trang (central, with typhoon considerations).
| 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) | 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 the best available — but expensive.
How We Reviewed and Ranked These Tools
We evaluated 5 solar software for installers platforms against Vietnamese market requirements:
Review methodology:
- documented-feature review with Vietnamese EPC teams in HCMC, Hanoi, and Da Nang
- Designed identical 500 kW factory rooftop projects across all platforms
- Validated SLD output against EVN grid connection requirements
- Tested tropical climate simulation accuracy against actual Vietnamese project data
- Benchmarked C&I financial modeling capabilities (self-consumption, DPPA)
- Research reference period: December 2025 through February 2026
| Criteria | Weight | What We Reviewed |
|---|---|---|
| EVN Compliance | 30% | SLD quality, protection devices, EVN acceptance |
| Tropical Climate Accuracy | 25% | Temperature derating, humidity, regional irradiance |
| C&I Financial Modeling | 20% | Self-consumption, DPPA, tariff analysis |
| Bankability | 15% | P50/P90 accuracy, lender acceptance |
| Pricing and Value | 10% | TCO for 3-user Vietnamese team |
Bottom Line: Best Solar Design Software for Vietnam
Vietnamese EPCs today typically use 3–4 disconnected tools: Aurora or HelioScope for design, AutoCAD for EVN documentation, PVsyst for bankability, and Excel for self-consumption financial modeling. That fragmentation wastes 3–4 hours per project, causes EVN rejections, and spreads a 3-person team’s spend across three or four separate subscriptions.
SurgePV consolidates the entire workflow — with automated EVN-compliant documentation, tropical-accurate simulation, and professional proposals — in 30–45 minutes per project, at $1,899 per user per year on the individual plan.
Our Recommendations:
- For C&I EPCs in Vietnam: SurgePV. EVN-compliant SLD generation, tropical modeling, and self-consumption financial analysis in one subscription instead of three.
- For residential installers: SurgePV for engineering depth, or Aurora if visual proposals justify the premium pricing.
- For bankability validation: PVsyst remains the standard. Use alongside SurgePV for large project financing above 10 MW.
- For utility-scale ground-mount (10 MW+): PVCase if you have CAD expertise and need terrain analysis. SurgePV for everything under 10 MW.
Vietnam’s solar market is not waiting for EPCs to modernize. The C&I segment is growing fast. Foreign manufacturers need renewable energy. The EPCs winning DPPA contracts and EVN approvals are the ones delivering professional proposals, accurate BOMs, and compliant electrical documentation same-day.

Frequently Asked Questions
What is the best solar design software in Vietnam?
SurgePV is the best all-in-one solar design tools for Vietnam, combining tropical climate modeling, automated EVN-compliant SLD generation, bankable P50/P90 simulations, and C&I self-consumption financial analysis in one cloud platform. Starting at $1,899 per user per year on the individual plan, it addresses Vietnam’s unique challenges — EVN interconnection, post-FiT self-consumption economics, and regional irradiance variations — in a single design workflow.
Is solar design software required for EVN grid connection in Vietnam?
EVN does not mandate specific software, but professional design tools are important for generating IEC-compliant SLDs, protection schemes, and technical documentation required for grid connection. Manual SLD creation in AutoCAD is where most EVN application errors originate. Automated SLD generation from actual design data reduces rejection risk and approval timelines.
Which solar software do Vietnamese EPCs use?
Vietnamese EPCs commonly use PVsyst (bankability), Aurora or HelioScope (design), and AutoCAD (EVN electrical documentation). This multi-tool approach means three or four separate subscriptions and renewals for a 3-user team. C&I installers are increasingly adopting SurgePV for integrated workflows that reduce costs and project timelines while handling self-consumption financial analysis.
Can solar software model Vietnam’s DPPA and self-consumption economics?
SurgePV models self-consumption ratios, hourly production vs load matching, EVN tariff savings, and DPPA financial scenarios. This analysis is important for C&I deals where foreign manufacturers need to demonstrate renewable energy procurement. Generic international tools (Aurora, HelioScope) lack these capabilities for the Vietnamese market.
What software do Vietnamese banks accept for solar financing?
Vietnamese banks and international DFIs (ADB, World Bank, JICA) accept reports from PVsyst (gold standard), SurgePV, and HelioScope meeting IEC bankability standards. Utility-scale requires PVsyst. C&I projects increasingly accept SurgePV’s P50/P90 reports.
How much does solar design software cost in Vietnam?
SurgePV starts at $1,899 per user per year on the individual plan with all features in one subscription. PVsyst does not publish list pricing. Aurora Solar publishes $159 per user per month for Basic, or $135 per user per month billed annually (aurorasolar.com/pricing/, checked 21 September 2026), and AutoCAD is licensed separately by Autodesk. An Aurora plus AutoCAD plus PVsyst route is therefore three separate subscriptions and renewals against SurgePV’s one, and because two of the three do not publish list pricing, a combined annual total cannot be sourced.
Does solar software account for Vietnam’s typhoon conditions?
Design software helps optimize panel layout and tilt angles for wind loading, but structural engineering for typhoon resilience is the EPC’s responsibility. SurgePV’s design tools support conservative system configurations for typhoon-prone central Vietnam. Pair software design with local structural engineering standards for typhoon zones.
Can I use cloud-based solar software with Vietnam’s internet infrastructure?
Yes. Cloud-based platforms like SurgePV work reliably on Vietnam’s 4G networks, which are well-developed in urban and industrial areas. Design files are small (5–10 MB). Cloud software offers major advantages for Vietnamese EPCs: teams in Hanoi and HCMC collaborate in real time, designs are accessible from factory site visits, and automatic backup prevents data loss.
