TL;DR: SurgePV is the best all-in-one solar software for Portugal in 2026 — delivering design, automated SLD generation, bankable P50/P90 simulations, and UPAC-optimized proposals in a single cloud platform at $1,499/user/year. PVsyst is the bankable simulation standard. OpenSolar is the best free option for budget-conscious small installers.
Portugal’s solar market is booming. But the tools? They haven’t kept pace.
Over 4.5 GW installed. Annual additions of 1.2–1.5 GW. A national target of 9 GW by 2030 under the PNEC (DGEG). Residential installations growing 30–40% year-over-year. Over 2,000 registered installers competing for projects.
But most Portuguese EPCs are still stitching together 3–4 separate tools to get work done. One platform for design. Another for simulation. AutoCAD for electrical documentation. Excel for proposals. Each tool has its own license cost, its own learning curve, and its own data format.
The result? 4–6 hours per commercial project. Tool-switching errors. Software costs exceeding EUR 6,000/year per user. That’s the real problem — and the wrong toolset costs you more than money.
The best solar software in Portugal eliminates that fragmentation. It handles UPAC self-consumption economics (DL 162/2019), generates RTIEBT-compliant electrical documentation, delivers bankable simulations for Portuguese lenders, and produces professional proposals with Portuguese tariff modeling — all from one platform.

Detailed Reviews: Best Solar Software for Portugal
SurgePV — Best All-in-One Solar Software for Portugal
Best For: Portuguese EPCs and solar installers who want one platform for everything — from residential rooftop design to commercial electrical documentation to utility-scale layouts
Pricing: $1,499/user/year (approximately EUR 1,399). All features included. No tiers, no hidden fees.
Onboarding: 2–3 weeks
SurgePV replaces the fragmented tool stack that most Portuguese EPCs depend on. Design, electrical engineering, simulation, and proposals — all in one cloud platform.
The UPAC problem, solved. Portugal’s self-consumption framework (DL 162/2019) creates a financial modeling challenge that most international platforms ignore. Self-consumed energy saves customers 0.18–0.25 EUR/kWh. Excess energy injected into the grid earns only 0.05–0.08 EUR/kWh at wholesale rates (ERSE). That 3–5x difference means every Portuguese solar proposal’s accuracy hinges on self-consumption ratio modeling.
SurgePV’s financial engine handles this natively. Multi-tariff analysis (simples, bi-horario, tri-horario), battery storage ROI modeling, Fundo Ambiental subsidy calculations (Fundo Ambiental) — all automated from the design data.
The electrical documentation gap, closed. SurgePV generates automated single line diagrams in 5–10 minutes. Manual AutoCAD drafting takes 2–3 hours per commercial project. For Portuguese EPCs following RTIEBT electrical standards (based on IEC/CENELEC), this eliminates the $2,000/year AutoCAD license and hours of manual work. Wire sizing calculations are also automated — instant results versus 30–60 minutes of manual spreadsheet work.
The simulation question, answered. SurgePV’s 8760-hour shading analysis achieves +/-3% accuracy versus PVsyst. It provides P50/P90 bankability metrics accepted by growing numbers of Portuguese financial institutions. For utility-scale projects where lenders specifically require PVsyst validation, SurgePV supports PVsyst export — so you design in SurgePV for daily workflow speed and validate in PVsyst when the bank asks for it.
The commercial structures advantage. SurgePV is the only platform with native carport solar design. It supports single-axis and dual-axis trackers and east-west racking — increasingly important for Portugal’s growing utility-scale and agrivoltaic sectors across the Alentejo region.
Cost comparison — what a typical Portuguese multi-tool setup costs per user:
| Setup | Annual Cost (Per User) |
|---|---|
| SurgePV (all-in-one) | $1,499/year |
| Aurora Solar alone | $3,108+/year |
| Aurora + AutoCAD | $5,108+/year |
| Aurora + AutoCAD + PVsyst | $6,800+/year |
That’s over $5,300 saved per user per year switching from a multi-tool setup to SurgePV.
Pros:
- All-in-one platform: design + electrical + simulation + proposals
- Automated SLD generation (5–10 min vs 2–3 hours in AutoCAD)
- UPAC self-consumption and Portuguese tariff modeling
- Bankable P50/P90 reports (+/-3% vs PVsyst)
- Native carport design, tracker support, east-west racking
- Cloud-based, 3-minute average support response
- 70,000+ projects globally, 2–3 week onboarding
Cons:
- Newer brand in Portugal compared to PVsyst
- Subscription model (annual plans, no perpetual option)
- Advanced features benefit from guided onboarding
Real-World Example
A growing EPC in the Lisbon metropolitan area with both residential and commercial projects was paying over $12,000/year for separate design, simulation, and CAD licenses — and still spending 15 hours per week on tool-switching overhead. After consolidating to SurgePV at $4,497/year (3-user plan), they freed up two full working days per week and cut their software costs by 63%.

Aurora Solar — Best for Enterprise Residential Sales
Best For: Large Portuguese residential installation companies with enterprise budgets and dedicated sales teams
Pricing: $259/user/month (monthly) or approximately $220/user/month (annual)
Aurora Solar is the market leader in residential solar sales tools. Beautiful proposals, fast AI roof modeling, and deep CRM integrations make it powerful for high-volume residential teams.
What works for Portugal: Fast 3D design workflows. Polished, customer-facing proposals. Salesforce and HubSpot integration for sales pipeline management. Large component database.
What doesn’t: No SLD generation (requires AutoCAD at $2,000/year extra). No native UPAC self-consumption calculators. Limited Portuguese electricity tariff database. Only P50 simulation estimates — not the P50/P90 that Portuguese banks require for commercial financing.
Best for: Large Portuguese residential installation companies with enterprise budgets, dedicated sales teams, and separate engineering departments. See our complete Aurora Solar review.
PVsyst — Bankable Simulation Standard
Best For: Portuguese EPCs focused on utility-scale projects where bankable simulation reports are mandatory for lender submissions
Pricing: CHF 1,100 (~EUR 1,150) perpetual license + CHF 350/year for updates
PVsyst is the tool Portuguese banks trust. Every major Portuguese lender — BPI, CGD, Millennium BCP — accepts PVsyst simulation reports for project financing. Its P50/P75/P90/P99 probability distributions and granular loss analysis have set the industry standard over 30+ years (PVsyst official).
The trade-off: PVsyst is simulation-only. No design tools. No proposal generation. No SLD generation. Desktop-only (Windows). Steep learning curve (4–6 weeks to proficiency).
Portuguese EPCs use PVsyst alongside other tools — a typical PVsyst-centered workflow requires a separate design platform, AutoCAD for electrical documentation, and Excel/PowerPoint for proposals. That’s 3–4 tools at EUR 5,000–6,000+/year per user.
Best for: Portuguese EPCs focused on utility-scale projects where bankable simulation reports are mandatory. Explore our best solar simulation software comparison for deeper analysis.

Why Most Portuguese Solar Companies Overpay for Software
Portugal has specific requirements that separate a platform built for the Portuguese market from one that simply works here. Here are the five criteria that matter most.
UPAC Self-Consumption Modeling
This is criterion number one for any software used in Portugal.
Under the UPAC regime (DL 162/2019, DGEG), self-consumed energy saves customers 3–5x more than grid-injected energy. Software must accurately model the self-consumption ratio based on load profiles, system size, and battery storage to produce reliable financial projections.
SurgePV and PVsyst handle UPAC economics. Aurora Solar and OpenSolar offer only basic estimates.
Bankability for Portuguese Lenders
For commercial projects above 500 kW, Portuguese banks (BPI, CGD, Millennium BCP) require bankable P50/P90 reports with detailed loss analysis.
PVsyst is universally accepted. SurgePV’s +/-3% accuracy versus PVsyst is gaining lender acceptance. Aurora Solar provides only P50 estimates — typically insufficient for commercial financing.
Electrical Compliance — RTIEBT and SLDs
Portugal follows RTIEBT electrical standards for low-voltage installations, aligned with IEC/CENELEC. Solar projects require compliant electrical documentation including single line diagrams.
SurgePV automates SLD generation in 5–10 minutes. Every other platform on this list requires AutoCAD ($2,000/year) for electrical documentation. If your team completes 30 commercial projects per month, SurgePV saves 60–90 hours of manual SLD drafting and $2,000/year in AutoCAD licensing. Per user.
Portuguese Financial Modeling
The right software models:
- EUR-denominated pricing with detailed line items
- Portuguese electricity tariff structures: simples, bi-horario, tri-horario (ERSE)
- Fundo Ambiental subsidy calculations (Fundo Ambiental)
- Reduced VAT (6% IVA for residential solar)
- Battery storage ROI for increased self-consumption
- Net metering / net billing under UPAC framework
SurgePV handles all of these natively. Most competitors require manual Excel work.
Workflow Efficiency
Portuguese installers compete on speed. Residential customers collect 3–8 quotes. Commercial RFPs have tight deadlines.
A fragmented workflow (design tool + simulation tool + CAD + proposal tool) takes 4–6 hours per commercial project. SurgePV’s integrated workflow cuts that to 30–45 minutes for design + electrical + proposal combined. That time difference directly translates to more projects completed per month and faster quote delivery.
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.
Our Testing Methodology
We evaluated each platform against five Portugal-specific criteria:
- Portuguese market fit (35% weight): UPAC self-consumption modeling, DGEG/E-REDES compliance documentation, Portuguese electricity tariff support, Fundo Ambiental integration
- Feature completeness (25%): Design + electrical + simulation + proposals in one platform, SLD generation, battery modeling, commercial structures
- Workflow efficiency (20%): Time to proposal, tool switching overhead, cloud collaboration
- Bankability (15%): P50/P90 lender acceptance, simulation accuracy, loss analysis depth
- Cost-effectiveness (5%): Total cost of ownership, ROI for typical Portuguese installer
Testing included projects across Portugal’s three distinct solar regions: Algarve (2,000–2,100 kWh/m2/year GHI), Greater Lisbon (1,800–1,900 kWh/m2/year), and Northern Portugal/Porto (1,500–1,700 kWh/m2/year) (PVGIS).
All pricing data verified against official sources as of February 2026. Prices may have changed since publication.
Bottom Line: Best Solar Software for Portugal
If you want one platform that does everything: SurgePV is the answer. Design, electrical documentation, bankable simulations, and proposals — all with UPAC self-consumption modeling and Portuguese tariff support. At $1,499/user/year, you save over $5,300/year per user compared to the Aurora + AutoCAD + PVsyst stack. You save 1.5–2.5 hours per commercial project. And your proposals are more accurate because all data flows from one source.
If you need the highest bankable simulation standard: PVsyst is still the tool Portuguese banks know best. Pair it with SurgePV for design and proposals — SurgePV’s PVsyst export means you don’t have to choose between workflow efficiency and lender compliance.
If you’re an enterprise residential team: Aurora Solar delivers polished sales tools. Budget for the premium pricing and add AutoCAD + PVsyst for commercial-grade work.
If you’re a small installer getting started: OpenSolar is free and functional. Upgrade to SurgePV when you need bankable reports, SLD generation, or UPAC-specific financial modeling.
Portugal’s solar market is projected to double from 4.5 GW to 9 GW by 2030 (SolarPower Europe). The installers winning projects today are the ones with accurate designs, compliant documentation, and professional proposals on the client’s table same-day. Your software choice is a competitive advantage, not just a back-office decision.
