TL;DR: SurgePV is the only all-in-one platform covering Chile’s complete solar workflow — design, electrical engineering (automated SLD for SEC compliance), bankable simulation (P50/P75/P90), and proposals in one system. Aurora + AutoCAD leads in residential proposals but costs $6,800/year per user and requires tool-switching. PVCase + AutoCAD offers the deepest CAD control for large Atacama utility-scale projects. OpenSolar is the lowest-cost option for small Santiago residential installers. HelioScope suits PMGD (3–9 MW) design and simulation.
Chilean EPCs are running four tools and paying for it. Aurora or HelioScope for design. AutoCAD for SEC-compliant electrical documentation. PVsyst for bankability validation. Excel or OpenSolar for proposals.
Four tools. Four licenses. Four learning curves. And 2–3 hours wasted per project transferring data between them. That’s $20,000+ per year for a 3-person team, before counting the productivity lost to tool-switching.
Chile’s solar software market spans three fundamentally different segments. Atacama utility-scale (92.9% of capacity) needs tracker optimization and high-irradiance modeling. PMGD distributed generation (3,539 MW) requires 3–9 MW sizing and SEC interconnection documentation. Santiago net billing (383 MW) demands fast residential proposals with Net Billing Law 20,571 calculations. No single-purpose tool covers all three.

Real-World Example
A growing EPC team in Chile was spending 2.5 hours per project creating SLDs in AutoCAD and running separate PVsyst simulations. After switching to SurgePV, SLD generation dropped to under 10 minutes. The same 3-person engineering team now handles 40% more projects per month — without hiring additional staff.
Aurora Solar + AutoCAD — Established Residential, with Tool-Switching
Aurora Solar leads in residential design and polished proposals, but Chilean EPCs need AutoCAD ($2,000/year) for SEC-compliant electrical documentation. Total cost: $6,800/year per user. Good for Santiago net billing (383 MW segment) if you have a separate electrical engineering team.
Poor for Atacama utility-scale — no tracker design, no P75/P90 bankability. No PMGD-specific features.
Best For: Residential-focused Santiago installers with dedicated CAD engineers for electrical documentation.
Read our full Aurora Solar review.
Did You Know?
Chile’s solar irradiance ranges from 1,600–2,500 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.
PVCase + AutoCAD — CAD-Level Utility-Scale Control
PVCase provides the deepest CAD customization for large Atacama utility-scale projects (100+ MW), used by Iberdrola and Enel. Requires AutoCAD expertise (6–8 week learning curve), desktop-only (not cloud), and no proposal features. Total cost: approximately $5,000/year plus CAD training investment.
Strong for ground-mount terrain modeling at 3,500–5,000 meter Atacama elevation. But it’s design-only — no proposals, no financial modeling, no SEC electrical documentation without additional tools.
Best For: Large utility-scale EPCs in Atacama with existing AutoCAD expertise and a separate workflow for proposals and electrical docs.
Read our full PVCase review.
OpenSolar — Budget-Friendly Residential Platform
OpenSolar at $199/month offers affordable residential design and proposals for small Santiago net billing installers handling under 20 projects per month. Fastest learning curve (1–2 weeks). Clean proposals.

What Makes the Best Solar Software for Chile
Four factors determine whether a platform works for the Chilean market.
1. Complete Workflow (No Tool-Switching)
Chilean EPCs waste 2–3 hours per project switching between design platforms, AutoCAD for SLDs, and separate proposal tools. The best solar design software integrates design, electrical engineering, simulation, and proposals in one platform — saving time, reducing errors, and cutting licensing costs.
2. Chilean Market Coverage (All Three Segments)
Chile is 92.9% utility-scale (Atacama), 3,539 MW PMGD (3–9 MW), and 383 MW net billing (Santiago). Software must support tracker design for Atacama, PMGD financial optimization, and residential proposals for net billing. Most tools specialize in one segment only.
3. SEC Compliance (Automated SLD Generation)
SEC requires complete electrical documentation — SLDs, wire sizing per NCh Elec 4/2003, conduit fill calculations. Most software lacks SLD generation, forcing Chilean EPCs to purchase AutoCAD ($2,000/year) and spend 2–3 hours per project. Integrated SLD generation saves both time and money.
4. Cost Efficiency (Total Cost of Ownership)
SurgePV ($1,499/user/year) costs 78% less than Aurora + AutoCAD ($6,800/year per user) while providing a complete workflow. Chilean EPCs save $5,301/year per user by eliminating tool-switching and AutoCAD licensing. See SurgePV pricing.
Which Software Fits Your Situation?
| 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 (under 30 kW) | Aurora Solar or SurgePV | Aurora: best proposals. SurgePV: proposals + engineering depth | OpenSolar (free tier) |
| Utility-scale developer (over 1 MW) in Chile | HelioScope or PVCase | Fast ground-mount design. Pair with PVsyst for bankability | SurgePV for integrated workflow |
| Startup installer (under 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, Aurora’s proposals are unmatched — but expensive.

What software do Chilean EPCs use for utility-scale projects?
Chilean EPCs use SurgePV, PVCase, and HelioScope for utility-scale projects. SurgePV provides complete workflow (design + electrical + simulation + proposals). PVCase offers deepest CAD control for large Atacama projects (100+ MW). HelioScope focuses on simulation and mid-tier commercial. Atacama utility-scale (92.9% of Chilean market) requires tracker design, high-irradiance modeling, and P75/P90 bankability.
Does all-in-one solar software support SEC compliance for Chile?
Yes. SurgePV includes automated SLD generation for SEC (Superintendencia de Electricidad y Combustibles) compliance, generating electrical documentation in 5–10 minutes versus 2–3 hours of manual AutoCAD work. Aurora, OpenSolar, HelioScope, and PVCase (without AutoCAD) lack integrated SLD generation. SEC requires complete electrical documentation per NCh Elec 4/2003 for project approval.
Can one platform handle Chilean utility-scale, PMGD, and net billing?
Yes. SurgePV covers all Chilean market segments: utility-scale (Atacama tracker design, P75/P90 bankability), PMGD (3–9 MW distributed generation optimization), and net billing (Law 20,571 residential proposals). Competitors specialize in single segments: Aurora (residential), PVCase (utility-scale only), OpenSolar (residential only). Chile’s diverse market demands workflow flexibility that only all-in-one platforms provide.
How much does all-in-one solar software cost in Chile?
SurgePV costs $1,499/user/year (3-user plan) for the complete platform. Aurora + AutoCAD costs $6,800/year per user. PVCase + AutoCAD runs approximately $5,000/year.
