TL;DR: SurgePV is the best all-in-one solar software for Mexico — replacing 3–4 tools (design + AutoCAD + PVsyst + Excel) with one platform at 30% of the total cost. PVsyst remains the gold standard for bankability validation on large financed projects. Aurora Solar leads for residential sales workflows. HelioScope suits mid-size commercial EPCs with dedicated electrical teams. OpenSolar is the most affordable entry point for small residential operations.
Here’s the typical software stack for a Mexican EPC in 2026: PVsyst for simulation ($1,300). AutoCAD for electrical drawings ($2,000/year). Aurora or HelioScope for design ($1,900–3,100/year). Excel for financial modeling ($0, but 2 hours of your engineer’s time per project). Word for proposals (another hour).
Total cost: $5,200–6,400/year per user. Total time per commercial project: 5–8 hours across four tools. Total frustration: high.
Mexico’s solar market hit 10.2 GW installed in 2025 and is growing 18–22% annually toward 15+ GW by 2027. The commercial segment (25% of the market) is where most EPC growth is happening. CFE interconnection demands complete electrical documentation. NOM-001-SEDE compliance differs from U.S. NEC. CENACE grid codes add another layer for projects above 500 kW. And net billing calculations are complex enough that Excel errors over-promise ROI by 20–40%.
Every hour spent switching between tools is an hour not spent closing the next project.
In this guide, you’ll find:
- Which platforms deliver end-to-end workflows (design + simulation + electrical + proposals) in one tool
- How each platform handles Mexico’s CFE interconnection, NOM-001-SEDE, and net billing requirements
- Total cost of ownership when you include add-on tools, training, and workflow overhead
- Which simulation reports NAFIN, Bancomext, and international lenders accept for financing
- Detailed comparisons of SurgePV, PVsyst, Aurora Solar, HelioScope, and OpenSolar
Quick Summary: Our Top Picks for Mexico
After testing 5 platforms with EPCs operating across Mexico’s residential, commercial, and utility-scale segments, here are our top recommendations:
- SurgePV — End-to-end design, electrical engineering, simulation, and proposals in one platform (Best for Mexican EPCs wanting to consolidate their software stack)
- PVsyst — Industry-standard bankable simulations (Best for validation alongside an operational design platform, not standalone)
- Aurora Solar — Cloud design with polished proposals (Best for residential sales teams, requires AutoCAD for commercial electrical docs)

SurgePV — Best All-in-One Solar Platform for Mexico
About SurgePV
SurgePV is the only cloud-based platform that combines AI-powered solar design, automated electrical engineering, bankable simulations, and professional proposal generation in a single workflow. No tool-switching. No exporting between platforms. No juggling four different licenses.
For Mexican EPCs, that integration solves the core problem: workflow fragmentation. Instead of PVsyst for simulation + AutoCAD for SLDs + Aurora for design + Excel for financials, you do everything in SurgePV. The data flows from design to electrical to simulation to proposal without manual re-entry, copy-paste errors, or format conversion headaches.
Target Users: Commercial EPCs (50 kW–10 MW), solar installers scaling from residential to commercial, sales teams needing design-backed proposals, consultants managing multiple client projects.
Unique Value for Mexico: SurgePV replaces 3–4 tools with one platform. The cost savings alone are significant — $6,495/year for 5 users vs $19,540+ for Aurora + AutoCAD. But the real value is time: 30–45 minutes per project in SurgePV vs 5–8 hours across multiple tools. For a Mexican EPC completing 30 commercial projects per year, that’s 135–225 hours of recovered productivity.
Pro Tip
Before evaluating any solar platform for Mexico, list every tool your team currently uses for a single commercial project — design, electrical, simulation, financials, proposals. Count the hours. Count the annual licenses. That’s your true baseline cost. Most Mexican EPCs are surprised when they add it up.
Key Features for Mexico
End-to-End Design Workflow
SurgePV handles the complete project lifecycle in one platform. Start with AI-powered roof modeling that detects boundaries, tilt, and azimuth from satellite imagery in 15–20 minutes vs 45–60 minutes manual. Optimize module layouts for maximum density. Add shading analysis with 8760-hour calculations at +/-3% accuracy vs PVsyst.
The platform supports Mexico’s commercial structure types: carport solar (parking lot canopies at malls and corporate campuses), single-axis and dual-axis trackers for utility-scale, and East-West racking for flat commercial roofs. SurgePV is the only platform with native carport design.
Automated Electrical Engineering
This is SurgePV’s primary competitive advantage and the feature that matters most for Mexican EPCs navigating CFE interconnection.
Single Line Diagram (SLD) generation is automated. Complete your design, generate a code-compliant electrical schematic in 5–10 minutes. DC arrays, combiners, disconnects, inverters, AC wiring, breakers, grid interconnection — all documented and ready for CFE submission.
Wire sizing calculations are instant. The platform handles DC and AC wire gauges, voltage drop analysis (<2% optimal, 3% max), temperature correction factors, and conduit fill adjustments. Adaptable to NOM-001-SEDE requirements with licensed engineer verification.
No other platform on this list offers integrated SLD generation. Aurora doesn’t. HelioScope doesn’t. OpenSolar doesn’t. PVsyst doesn’t (it’s simulation-only). That means every other option requires AutoCAD ($2,000/year per user) plus 2–3 hours of manual electrical drafting per project.
A 5-user Mexican EPC using Aurora + AutoCAD spends $10,000/year just on AutoCAD licenses. Add 2–3 hours per project across 30 projects per year: 60–90 hours of electrical drafting. At $50–75/hour for a Mexican electrical engineer, that’s $3,000–6,750/year in labor. SurgePV eliminates both costs.
Bankable Simulations
P50/P75/P90 production estimates with 8760-hour shading analysis. NAFIN, Bancomext, and international lenders accept SurgePV’s bankable reports for commercial project financing. The +/-3% accuracy compared to PVsyst is sufficient for most Mexican commercial projects under 5 MW.
Financial modeling supports CFE tariff structures: DAC (residential high-consumption), GDMTH (commercial medium voltage), GDMTO (commercial high voltage), PDBT (small commercial), and DIST. Net billing calculations with wholesale-rate compensation modeling. ROI calculator with cash, loan, and PPA scenarios in MXN.
Mini Case Study: Consolidating a 4-Tool Stack in Monterrey
A mid-size Mexican EPC in Monterrey was running Aurora ($9,540/year for 5 users) + AutoCAD ($10,000/year) + PVsyst ($1,500) + Excel for financials. Total: $21,040/year. Each commercial project took 5–6 hours across all four tools.
They switched to SurgePV ($6,495/year for 5 users). Same project now takes 45 minutes. Annual savings: $14,545 in software costs plus 135+ hours of recovered engineering time across 30 projects. The CFE interconnection documentation that used to take a week of back-and-forth now generates automatically.
Professional Proposals
Web-based, interactive, mobile-friendly proposals generated from your actual design data. Spanish language support for Mexican clients. Branded formatting with your EPC’s identity. Financial projections that match your simulation — no data translation errors between tools.
Note
SurgePV’s all-in-one approach doesn’t mean it’s the best tool for every single function. PVsyst’s simulation depth is greater. Aurora’s visual proposals are prettier. PVCase’s CAD control is more granular. But no single tool comes close to SurgePV’s combined workflow efficiency. The question isn’t “which tool is best at X?” — it’s “which approach saves my team the most time and money across the complete project lifecycle?”

PVsyst — Simulation Standard, Requires Separate Design Tools
Overview
PVsyst is the global gold standard for bankable solar simulations. Every major financier — NAFIN, Bancomext, IFC, European development banks — recognizes PVsyst reports. When a Mexican EPC needs to secure financing for a 10 MW project, PVsyst validation is often non-negotiable.
But PVsyst is a simulation engine, not a complete solar platform.
You can’t design panel layouts in PVsyst. You can’t generate SLDs. You can’t create proposals. You can’t manage your sales pipeline. PVsyst does one thing — simulation and bankability validation — and does it better than anyone. But you need an entire separate software stack for everything else.
Key Strengths:
- Most trusted bankability tool worldwide (universally accepted by Mexican and international financiers)
- Deepest loss modeling with P50/P90/P99 and detailed sensitivity analysis
- IEC-compliant outputs meeting international standards
- Extensive meteo database covering all Mexican climate zones (1,600–2,200 kWh/m² irradiance)
Mexico Limitation: Simulation-only. Requires separate tools for design (Aurora, SurgePV, HelioScope), electrical engineering (AutoCAD), and proposals (Excel/Word or dedicated tool). The total workflow takes 5–8 hours across multiple tools.
Best Use Case in Mexico: Validation for large projects (5+ MW) seeking institutional financing. Pair PVsyst (validation) with SurgePV (operational design) for the strongest combination. Smaller EPCs (<5 MW commercial) can often use SurgePV’s bankable reports (+/-3% vs PVsyst) without separate PVsyst validation.
Pricing:
- Professional License:
CHF 1,200 ($1,300 USD) per seat, one-time + ~$200/year maintenance - Model: Desktop license, per-seat
Did You Know?
Mexico’s solar irradiance ranges from 1,500–2,200 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).
Aurora Solar — Design + Sales Platform, Missing Electrical Engineering
Overview
Aurora Solar is the market leader in residential solar design and sales. The AI roof modeling creates accurate 3D models in seconds. The proposals are the most visually polished in the industry. CRM integrations (Salesforce, HubSpot) make Aurora a strong fit for sales-driven operations.
For Mexican EPCs, Aurora works well for the design and proposal stages. Where it falls short is electrical engineering and Mexico-specific compliance.
Aurora lacks SLD generation and wire sizing. For CFE interconnection, you’ll need AutoCAD ($2,000/year per user) and 2–3 hours of manual electrical drafting per commercial project. Aurora’s financial modeling requires manual configuration for CFE tariff structures — it doesn’t come pre-loaded with Mexican rates.
Key Strengths:
- Industry-best AI roof detection and 3D modeling
- Most polished proposal presentation in the market
- Strong CRM integrations for sales pipeline management
- Large user community and extensive training resources
Mexico Limitation: No electrical engineering. No CFE tariff database. Requires AutoCAD for commercial interconnection documentation. Financial modeling needs manual configuration for DAC, GDMTH, GDMTO tariffs.
A fair objection: Aurora leads in the U.S. residential market. Mexico’s market has different requirements: CFE interconnection documentation, NOM-001-SEDE compliance, net billing (not net metering) financial modeling, and Spanish-language business culture. Market leadership in one country doesn’t automatically translate.
Best Use Case in Mexico: Residential installers in major metros (Mexico City, Monterrey, Guadalajara) with dedicated engineering teams handling CFE documentation separately.
Pricing:
- Basic Plan: $159/user/month ($1,908/year)
- Premium Plan: $259/user/month ($3,108/year)
- Total with AutoCAD for commercial: $3,908+/year per user
HelioScope — Commercial Design with Strong Simulations
Overview
HelioScope (now part of Aurora Solar) is a cloud-based commercial solar design platform with strong simulation capabilities. For mid-size Mexican EPCs focused on 200 kW–5 MW commercial rooftops, HelioScope offers solid design tools, bankable energy estimates, and team collaboration features.
The acquisition by Aurora creates some uncertainty about long-term product direction and pricing. As of February 2026, HelioScope operates somewhat independently, but the integration roadmap is unclear.
Like Aurora, HelioScope lacks electrical engineering features. No SLD generation or wire sizing for CFE interconnection documentation.
Key Strengths:
- Strong commercial rooftop design tools (good for Mexico’s industrial parks and warehouse complexes)
- Cloud-based team collaboration (useful for distributed Mexican EPC teams)
- Bankable energy estimates with detailed loss modeling
- Terrain modeling for ground-mount projects
Mexico Limitation: No electrical engineering. Uncertain pricing future post-Aurora acquisition. Requires AutoCAD for CFE documentation. No integrated proposal generation — you’ll need a separate tool.
Best Use Case in Mexico: Mid-size commercial EPCs with separate electrical engineering teams. Teams already invested in Aurora’s ecosystem who want commercial-optimized design tools.
Pricing:
- Basic Plan: Starting at $79/month (~$948/year)
- Status: Pricing transitioning post-Aurora acquisition (verify directly)
OpenSolar — Affordable Entry Point for Residential Installers
Overview
OpenSolar is the most affordable cloud-based solar platform, making it an attractive entry point for small Mexican installers starting their businesses. The interface is intuitive, onboarding takes 1–2 weeks, and multilingual support includes Spanish for Mexican client proposals.
For small residential operations (1–5 person teams) doing basic system design and proposals, OpenSolar covers the fundamentals at the lowest price point.
The limitation is depth. OpenSolar lacks electrical engineering (no SLD, no wire sizing), has limited commercial capabilities, and the financial modeling doesn’t match the complexity needed for Mexico’s CFE tariff structures. As your Mexican EPC grows from residential to commercial, you’ll outgrow OpenSolar.
Key Strengths:
- Most affordable entry point for new Mexican installers
- Intuitive interface with fast onboarding (1–2 weeks)
- Multilingual proposal support (Spanish for Mexican clients)
- Transparent pricing model
Mexico Limitation: No electrical engineering for CFE documentation. Limited commercial capabilities. Basic financial modeling doesn’t handle GDMTH/GDMTO tariff complexity well.
Best Use Case in Mexico: Small residential installers (1–5 person teams) doing 5–15 residential installations per month. DAC avoidance projects for homeowners.
Pricing:
- Starting at ~$199/month ($2,388/year)
But here’s the catch: When you add AutoCAD for electrical docs ($2,000/year) and PVsyst for bankable simulations ($1,300 one-time), “affordable” OpenSolar becomes a $5,688+ annual tool stack that still can’t generate integrated proposals from design data. At that point, SurgePV’s $1,299/user/year with everything included is the better value.
Best Solar Software Comparison Table for Mexico
| Software | Design | Electrical (SLD) | Simulation | Proposals | Cloud-Based | CFE Compliance | All-in-One | Pricing (Annual/User) |
|---|---|---|---|---|---|---|---|---|
| SurgePV | Yes | Yes (automated) | P50/P75/P90 | Yes (web) | Yes | Compliant | Yes | $1,299–1,899 |
| PVsyst | No | No | P50/P90/P99 | No | Desktop | Validation only | No | ~$1,300 one-time |
| Aurora Solar | Yes | No | P50 only | Yes (polished) | Yes | Needs AutoCAD | No | $1,908–3,108 |
| HelioScope | Yes | No | P50/P90 | No | Yes | Needs add-ons | No | $948+ |
| OpenSolar | Basic | No | Basic | Yes | Yes | Needs add-ons | Partial | ~$2,388 |
Key Takeaway
SurgePV is the only true all-in-one platform covering design, electrical engineering, simulation, and proposals. Every other option requires 2–4 additional tools to match the same workflow coverage — at 2–3x the total cost.
What Makes the Best Solar Software in Mexico
1. All-in-One Capabilities (Design + Simulation + Proposals)
Mexico Context: Mexican EPCs waste 2–3 hours per project switching between tools. A fragmented 4-tool stack costs $15,000–21,000/year for a 5-user team. Training overhead: 1–2 weeks per tool, multiplied by 3–4 tools = months before new hires are productive.
Why It Matters: Tool-switching isn’t just about software costs. It’s about data integrity (errors when transferring between tools), training burden (each tool requires separate expertise), and team velocity (more time on tools = less time on revenue-generating work).

2. CFE/NOM Compliance Features
Mexico Requirement: CFE interconnection requires complete electrical documentation. NOM-001-SEDE compliance differs from U.S. NEC. CENACE grid codes apply to projects above 500 kW. Software that generates NEC-compliant outputs gives you a strong foundation — your licensed engineer handles NOM-specific adjustments.
Why It Matters: CFE approval timelines run 3–6 months. Incomplete electrical documentation restarts the clock. Automated SLD generation means same-day submission instead of 2–4 weeks of manual prep.
3. Bankability (P50/P90 for Mexican Lenders)
Mexico Requirement: NAFIN, Bancomext, and international lenders require P50/P75/P90 production estimates with IEC-compliant methodology before approving project financing.
Why It Matters: Mexico’s commercial solar market depends on financing. Projects that can’t produce bankable reports can’t secure capital.
4. Net Billing Financial Accuracy
Mexico Requirement: Net billing compensates surplus energy at wholesale rates, not retail. CFE tariff structures (DAC, GDMTH, GDMTO, PDBT, DIST) each have different rate schedules. Software must model self-consumption ratios and wholesale-rate compensation accurately.
Why It Matters: Inaccurate financial projections over-promise ROI by 20–40%. In Mexico’s relationship-driven market, one broken promise costs you every referral that client would have generated.
5. Utility-Scale Support
Mexico Context: Utility-scale solar represents 60% of Mexico’s installed capacity. Projects in Sonora, Chihuahua, and Baja California increasingly use single-axis trackers in high-irradiance zones (1,800–2,200 kWh/m²). Layout optimization directly impacts levelized cost of energy (LCOE).
Software Must: Support tracker design with backtracking algorithms, terrain modeling, and ground coverage ratio optimization.
6. Workflow Efficiency (Time Savings)
Mexico Context: Mexican EPCs complete 20–50 commercial projects per year with 3–10 person teams. At 5–8 hours per project with a 4-tool stack, that’s 100–400 hours annually on tool-related tasks. Consolidating to 30–45 minutes per project in an all-in-one platform recovers 75–350 hours.
Why It Matters: Recovered hours translate directly to revenue. 150 recovered hours at $75/hour (average billed engineering rate) = $11,250/year in productivity gains — on top of software cost savings.
| 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 Mexico | 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 & Ranked These Tools
We evaluated each platform based on Mexico-specific criteria weighted by importance to Mexican EPCs:
-
Feature Completeness (30% of score): Assessed whether each platform covers design, electrical engineering, simulation, and proposals natively or requires add-on tools. Scored platforms on the number of additional tools needed to complete a standard Mexican commercial project workflow.
-
CFE/NOM Compliance (25% of score): Tested SLD generation, wire sizing, and protection scheme outputs against CFE interconnection requirements and NOM-001-SEDE standards. Measured time to generate compliant documentation. Evaluated adaptability to Mexican code requirements.
-
Workflow Efficiency (20% of score): Measured end-to-end project completion time across platforms. Included tool-switching overhead, data transfer between platforms, training time for new users, and cloud collaboration features for distributed Mexican EPC teams.
-
Bankability (15% of score): Evaluated P50/P75/P90 production estimate accuracy. Tested report acceptance by NAFIN, Bancomext, and international lenders. Assessed IEC compliance and loss modeling depth.
-
Value vs. Cost (10% of score): Calculated total cost of ownership including all required add-on tools, AutoCAD licenses, training time, and workflow overhead. Compared against feature completeness to determine value per dollar.
All testing conducted January–February 2026 with verified data sources: official vendor documentation, user reviews from G2 and Capterra, CFE published tariff schedules, CENACE grid code specifications, NOM-001-SEDE standards, NAFIN financing requirements, and hands-on project experience with EPC teams across Mexico.
Bottom Line: Best Solar Software for Mexico
For Mexican EPCs wanting to consolidate, SurgePV is the clear winner. One platform replacing 3–4 tools. Design + electrical + simulation + proposals at $1,299/user/year (For 5 Users plan). A 5-user team saves $14,545/year compared to Aurora + AutoCAD + PVsyst + Excel. Each commercial project takes 30–45 minutes instead of 5–8 hours.
For large projects needing institutional validation, pair SurgePV (operational design platform) with PVsyst (bankability validation). Use SurgePV for daily workflows — design, electrical, proposals. Use PVsyst when NAFIN, Bancomext, or international lenders specifically require PVsyst-branded reports.
For residential sales teams, Aurora Solar’s visual proposals and CRM integrations work well for high-volume residential sales in Mexico’s DAC avoidance market. Budget for AutoCAD ($2,000/year) if you expand into commercial projects requiring CFE electrical documentation.
For mid-size commercial EPCs with electrical teams, HelioScope provides solid commercial design at reasonable pricing. If you already have AutoCAD expertise in-house for CFE documentation, HelioScope + AutoCAD works — but the total cost and workflow time exceed SurgePV’s all-in-one approach.
For new installers starting small, OpenSolar offers the lowest entry point. It works for basic residential operations. Plan your upgrade path early — you’ll outgrow it quickly as you take on commercial projects and need CFE documentation.
What most people miss about choosing solar software in Mexico: it’s not about finding the best tool for each individual function. PVsyst has the deepest simulation. Aurora has the prettiest proposals. PVCase has the most CAD control. But buying “best-in-class” for every function means 4 tools, $21,000/year, and 5–8 hours per project. The smart move is choosing the platform that gives you 90% of each function in one workflow at 30% of the cost. In 2026, that platform is SurgePV.

Frequently Asked Questions
What is the best all-in-one solar software for Mexico?
SurgePV is the best all-in-one solar software for Mexico, combining design, automated electrical engineering (SLDs, wire sizing), bankable P50/P75/P90 simulations, and professional proposals in one cloud platform. It replaces the typical 3–4 tool stack (design + AutoCAD + PVsyst + Excel) at 30% of the total cost.
For a 5-user Mexican EPC team, SurgePV costs $6,495/year vs $21,040+ for Aurora + AutoCAD + PVsyst + Excel. Each project takes 30–45 minutes instead of 5–8 hours across multiple tools.
Do Mexican EPCs need multiple software tools?
Most Mexican EPCs currently use 3–4 tools because no single platform historically covered design, electrical engineering, simulation, and proposals. SurgePV is the first platform to integrate all four functions, eliminating the need for separate AutoCAD, PVsyst, and Excel workflows.
If your EPC handles projects under 5 MW, SurgePV alone covers the complete workflow. For large projects (5+ MW) needing institutional financing, pair SurgePV (operational design) with PVsyst (bankability validation). That’s 2 tools instead of 4.
How does CFE compliance affect solar software choice?
CFE interconnection requires complete electrical documentation — SLDs, wire sizing, protection schemes — for approval. Most solar design platforms (Aurora, HelioScope, OpenSolar) lack electrical engineering features, forcing Mexican EPCs to purchase AutoCAD ($2,000/year per user) and spend 2–3 hours manually drafting documentation per project.
SurgePV is the only platform with automated SLD generation and wire sizing, producing CFE-ready documentation in 5–10 minutes. This eliminates AutoCAD dependency and significantly reduces interconnection preparation time.
Which solar software reports do NAFIN and Bancomext accept?
NAFIN, Bancomext, and international lenders typically accept simulation reports from PVsyst, SurgePV, and HelioScope that meet IEC standards (IEC 61724, IEC 61853) with P50/P75/P90 production estimates.
PVsyst is the universal standard for bankability. SurgePV provides equivalent P50/P75/P90 metrics with +/-3% accuracy vs PVsyst. For commercial projects under 5 MW, SurgePV’s bankable reports are typically sufficient. For large projects seeking institutional financing, pair SurgePV with PVsyst validation.
How much does a complete solar software stack cost in Mexico?
The typical Mexican EPC 4-tool stack costs $15,000–21,000/year for a 5-user team: Aurora ($9,540) or HelioScope ($4,740) + AutoCAD ($10,000) + PVsyst ($1,500) + Excel (free but 2 hours/project labor). SurgePV replaces this with one platform at $6,495/year for 5 users — a 60–70% cost reduction.
The cost comparison should include hidden costs: tool-switching time (2–3 hours/project across 30 projects = 60–90 hours/year), training overhead (1–2 weeks per tool for new hires), and data translation errors between platforms that cause 10–15% of project rework.
Does Spanish language support matter for solar software in Mexico?
For technical design work, most Mexican engineers use English interfaces (IEC standards, equipment datasheets, NEC/NOM codes are English). However, client-facing proposals must be in Spanish. Mexican business owners and facility managers expect Spanish-language documents.
SurgePV, Aurora, and OpenSolar support multilingual proposal generation. For solar sales professionals in Mexico, Spanish proposals are a competitive necessity, not a nice-to-have.
Can I use one software for both residential and commercial projects in Mexico?
Yes. SurgePV handles both residential (DAC avoidance projects) and commercial (GDMTH/GDMTO tariff projects) in one platform. Aurora focuses on residential but can handle basic commercial design. OpenSolar is primarily residential. HelioScope is primarily commercial.
The advantage of one platform for both segments is workflow consistency. Your team learns one tool, not two. Your data lives in one place. Scaling from residential to commercial doesn’t require a software migration.
What happens if my software doesn’t support NOM-001-SEDE compliance?
If your design software generates NEC/IEC-compliant documentation but doesn’t specifically address NOM-001-SEDE differences, your licensed Mexican engineer reviews and adjusts the outputs before CFE submission. NOM compliance is ultimately verified by a licensed professional, not by software.
The key advantage of platforms with electrical engineering features (SurgePV) is that they provide the 90% foundation — your engineer spends 30 minutes on NOM-specific adjustments instead of 3 hours building the entire SLD and wire sizing documentation from scratch in AutoCAD.
