TL;DR: SurgePV is the best solar design software for Ireland — automated SEAI-compliant SLD generation, bankable P50/P75/P90 simulations, and Ireland-specific financial modelling in one cloud platform. PVsyst remains the bankability standard for utility-scale projects requiring international financing.
Ireland’s solar market is accelerating fast. The country reached 1.2 GW of installed PV capacity by end of 2025 — and the government’s Climate Action Plan targets 8 GW by 2030 (SEAI Solar Energy Overview). That’s nearly 7x growth in five years. SEAI grants, the Clean Export Guarantee, and some of Europe’s highest electricity prices are all driving adoption.
But designing solar systems here comes with its own set of headaches. ESB Networks grid connection documentation. DS3 grid code compliance. SEAI microgeneration grant paperwork. I.S. EN 62446 commissioning standards. Most solar design tools were built for the US or continental European markets — and they don’t handle any of this natively. That means hours of manual work on every single project.
If you’re designing solar systems in Ireland, you need a platform that handles ESB Networks compliance, produces bankable P50/P90 reports for Irish lenders, and keeps your team moving fast on residential proposals.
We tested and compared the top 5 solar design software platforms for the Irish market, evaluating each on regulatory compliance, simulation accuracy, electrical engineering capabilities, and pricing.
In this guide, you’ll learn:

Best Solar Design Software in Ireland (Detailed Reviews)
SurgePV — Best End-to-End Solar Design Platform for Ireland
Best For: EPCs and installers across all segments
Pricing: $1,899/year (3 users); $1,499/user/year (For 3 Users plan)
Onboarding: 2–3 weeks
SurgePV is an end-to-end solar design and engineering platform that combines layout design, electrical engineering, bankable simulations, and proposal generation in a single cloud-based tool.
For the Irish market, that matters more than you might think. Most competing platforms force you to switch between 2–3 separate tools for a complete commercial project. Design in one tool, export to AutoCAD for single line diagrams (SLDs), then run a separate simulation in PVsyst. That workflow adds 2–3 hours per project and costs thousands in extra licenses. SurgePV eliminates that entirely.
Key Features for Ireland
- Automated SLD generation — Creates code-compliant electrical schematics in 5–10 minutes, meeting ESB Networks and DS3 documentation requirements. Manual AutoCAD drafting takes 2–3 hours for the same output.
- P50/P75/P90 bankability metrics — Produces the production estimates Irish banks (Bank of Ireland, AIB) and commercial lenders require. Accuracy within +/-3% of PVsyst. Your financing applications include the bankability data lenders actually need — not just optimistic P50 estimates that get questioned.
- 8760-hour shading analysis — Hour-by-hour simulation across the full year, critical for Ireland’s maritime climate with lower irradiance and frequent cloud cover (900–1,100 kWh/m²/year).
- Native carport and tracker design — SurgePV is the only platform with built-in solar carport design. Single-axis and dual-axis tracker support included. With Ireland’s growing commercial segment and agrivoltaics interest, this is a real differentiator.
- Financial modeling — Supports custom utility rate input, enabling CEG (Clean Export Guarantee) tariff analysis and SEAI grant deduction modeling for accurate ROI calculations.
- Wire sizing and voltage drop calculations — Instant automated calculations per IEC and ETCI standards, eliminating manual spreadsheet work. No more cross-referencing code tables — and zero risk of undersized cables failing ESB inspection.
Pro Tip
SurgePV’s automated SLD generation saves 2–3 hours per project compared to manual AutoCAD drafting — and eliminates the $2,000/year AutoCAD license entirely. Book a demo to see it in action.

Who SurgePV Is Best for in Ireland
- Commercial EPCs handling 50 kW–10 MW projects needing ESB Networks-compliant SLDs
- Residential installers who want design, engineering, and SEAI-ready proposals in one tool
- Companies needing bankable P50/P90 reports accepted by Bank of Ireland and AIB
- Teams looking to eliminate AutoCAD dependency and reduce per-project costs
Limitations
- Newer platform — smaller user community in Ireland compared to PVsyst or Aurora
- Irish utility rates (ESB, Energia, SSE Airtricity) require manual input (not pre-loaded)
Real-World Example: A mid-size EPC team in Dublin was spending 3 hours per project creating SLDs in AutoCAD and another 2 hours assembling ESB Networks TA documentation. After switching to SurgePV, SLD generation dropped to under 10 minutes and TA documents are auto-populated. With the same 3-person engineering team, they now handle 40% more projects per month — without hiring additional staff.

Which Software Is Right for Your Use Case?
| Your Use Case | Best Software | Why | Alternative |
|---|---|---|---|
| Multi-segment EPC (residential + commercial + utility) | SurgePV | End-to-end platform covers all project types, automated SLD generation, P50/P90 bankability, proposals | PVsyst + AutoCAD (higher cost, longer workflow) |
| Residential-only installer (50+ projects/year) | SurgePV or Aurora | SurgePV: Complete workflow at $1,899/year. Aurora: Best-in-class proposals but $3,600–6,000/year | OpenSolar for budget-conscious teams |
| Commercial C&I specialist (50 kW–1 MW) | SurgePV or HelioScope | SurgePV: Automated SLDs save 2–3 hrs/project. HelioScope: Fast cloud design but requires external CAD | PVsyst + design tool of choice |
| Engineering firm (simulation-only, no sales) | PVsyst | Gold standard bankability, universally accepted by lenders, deepest technical simulation | SurgePV if you want design + simulation in one tool |
| Projects requiring bank financing | PVsyst or SurgePV | P50/P90 bankability reports accepted by lenders. PVsyst = universal acceptance, SurgePV = growing acceptance | HelioScope (some lenders, not all) |
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.

Bottom Line: Best Solar Design Software for Ireland
Ireland’s solar market is scaling fast — but the regulatory environment (ESB Networks, DS3, SEAI, ETCI) makes software selection more important than in simpler markets.
Here’s how to choose:
For commercial EPCs and multi-segment teams: SurgePV delivers the most complete workflow. Automated SLD generation for ESB Networks compliance, P50/P90 simulations for bank financing, SEAI grant-ready proposals for residential projects, and 98% BOM accuracy — all in one platform at $1,899/year for 3 users.
For commercial-only EPCs with complex rooftops: Aurora Solar offers advanced 3D modeling and remote site assessment, but budget-conscious Irish teams should weigh the $3,600–6,000/year cost and lack of ESB documentation automation.
For simulation-only needs: PVsyst remains the bankability gold standard, especially for utility-scale projects needing Irish bank approval. Pair it with SurgePV or AutoCAD for the complete design workflow.
For residential-focused installers: OpenSolar provides fast proposals and CRM at an affordable price, though ESB and SEAI documentation require manual effort.
Ireland’s solar sector isn’t slowing down. The installers and EPCs winning projects today are the ones producing ESB Networks-compliant documentation and bankable simulations faster than their competitors — not the ones still drafting SLDs by hand in AutoCAD. Your solar software choice is a competitive advantage, not just a back-office decision.

When You May Not Need Advanced Solar Software
Professional solar design software makes sense for most Irish installers — but not always.
Small residential installers with outsourced engineering: If you install 20–50 residential systems per year and outsource electrical engineering to a third party, paying for full design software may not make sense. Basic tools like PVWatts combined with an external engineering firm (€500–1,000 per project) can be more cost-effective than a $1,899–6,000/year subscription.
Installers using manufacturer-provided designs: Some installers work exclusively with solar distributors who provide turnkey system designs as part of their supply agreements. If your supplier handles layout, electrical documentation, and permit drawings at no extra cost, standalone design software may be redundant.
Very small projects under 5 kW: For tiny residential systems, manual calculations and manufacturer spec sheets often suffice. The 2–3 hours saved per project with professional software may not justify the investment if you’re only installing 10–20 micro-systems per year.
When project volume is too low: Design software ROI depends on volume. Fewer than 20–30 projects annually means the time savings may not offset subscription costs. Calculate your break-even: (annual software cost) / (hours saved per project × hourly labour cost).
Bottom line: Professional design software makes sense when you’re designing 30+ projects per year, handling commercial/utility-scale work, or need to produce bankable simulations for financing. For smaller operators or niche service businesses, simpler tools may be the better choice.
Frequently Asked Questions
What is the best solar design software in Ireland?
SurgePV is the best overall solar design software for Ireland in 2026. It combines design, automated SLD generation (meeting ESB Networks and DS3 requirements), P50/P90 bankable simulations, and proposal tools in one cloud-based platform at $1,899/year for 3 users. For simulation-only needs, PVsyst remains the bankability standard.
Do I need special software for ESB Networks grid connections?
Yes. ESB Networks requires detailed Technical Assessment (TA) and Basis of Design (BoD) documentation — including single line diagrams, protection schemes, and inverter specifications — for grid connection approval. Software like SurgePV auto-generates ESB-compliant TA documents. Manual documentation takes 4–8 hours per project; automated tools reduce this to under 30 minutes and help ensure first-time approval.
How much does solar design software cost in Ireland?
Solar software costs range from $625/year (PVsyst standalone) to $6,000/year (Aurora Solar). SurgePV starts at $1,899/year for 3 users with all features included. Consider total cost of ownership — tools without SLD generation often require an additional $2,000/year AutoCAD license.
Does solar design software support SEAI grants?
SurgePV auto-generates SEAI-compliant pre-works and post-works documentation for Ireland’s Microgeneration Support Scheme (EUR 2,100–2,400 grants). Other platforms require manual grant calculations and documentation, adding 2–3 hours per residential project. See how SurgePV automates proposals.
Which solar simulation software do Irish banks accept for project financing?
Irish banks (Bank of Ireland, AIB, Ulster Bank) typically accept P50/P90 reports from PVsyst and SurgePV that meet IEC 61853 standards. SurgePV simulations achieve +/-3% accuracy compared to PVsyst. HelioScope reports are accepted by some, but not all, Irish lenders. Learn more about bankability.
How accurate is solar design software for Ireland’s weather?
Software using Met Eireann or PVGIS data for Ireland achieves +/-5% accuracy vs. real project performance over 12 months. Ireland’s solar irradiance (900–1,100 kWh/m²/year) is lower than continental Europe. Use software with Ireland-specific weather data and conservative degradation assumptions (0.5%/year). See SurgePV’s shading analysis.
Can solar design software model battery storage for Ireland?
Yes. SurgePV, Aurora Solar, and OpenSolar support battery storage design and financial modeling for Irish residential and commercial systems. Battery storage is increasingly common in Ireland for maximising self-consumption and export revenue under the Clean Export Guarantee (CEG).
Is free solar design software good enough for Irish installers?
Free tools like PVWatts and SolarEdge Designer are suitable for basic residential estimates but lack ESB Networks integration and SEAI grant automation needed for professional Irish installations. For installers managing 50+ projects/year, paid solar proposal software platforms like SurgePV deliver 10x ROI through time savings and higher close rates.
