Ireland is a small market with a heavy administrative load per job. That combination decides the software question before any feature comparison starts. A domestic installer here spends more hours on grant paperwork and connection notification than on layout, and the sky is diffuse enough that the modelling arguments imported from sunnier markets do not transfer cleanly.
Direct answer. Solar software in Ireland splits into six layers: design and simulation, sales and proposal, SEAI grant and ESB Networks documentation, monitoring, CRM and operations, and procurement. The Irish distinctive is that grant administration is a real operational layer, and the market is small enough that per-seat-heavy stacks rarely pay for themselves.
TL;DR
- Six layers, and in Ireland the grant administration layer eats the most staff hours.
- Domestic grant work runs through SEAI-registered contractors, with electrical work to I.S. 10101.
- Grid connection is notified to ESB Networks under NC6 for smaller systems or NC7 for larger ones.
- Diffuse Atlantic sky means beam-only shading models overstate losses, so optimiser payback is often marginal.
- Total stack cost runs from roughly €1,000 to €25,000 a year depending on stage.
What “Solar Software” Actually Means in Ireland
Six jobs sit under the phrase, and the Irish weighting is unusual.
Design and simulation. Layout, string sizing, shading, and yield, above 51 degrees north where winter shadows run long.
Sales and proposal. Customer-facing savings documents, usually with the grant deducted up front.
SEAI grant and ESB Networks documentation. Grant administration plus the connection notification. This is the Irish layer.
Monitoring. Post-commissioning production, mostly from the inverter vendor’s portal.
CRM and operations. Lead tracking, survey scheduling, crew dispatch.
Procurement. Distributor sourcing.
The Irish Solar Software Stack, Layer by Layer
| Layer | Representative tools | Who uses it | Typical cost per year |
|---|---|---|---|
| Design and simulation | PVsyst, SurgePV, HelioScope, OpenSolar | Designers | €0 to €2,900 per seat |
| Sales and proposal | OpenSolar, SurgePV, sector tools | Sales team | €0 to €1,800 per seat |
| SEAI grant and ESB Networks docs | Portals plus internal process | Administration | Process cost, not licence |
| Monitoring | Inverter vendor portals | O&M | Bundled with hardware |
| CRM and operations | HubSpot, Pipedrive, sector CRMs | Everyone | €250 to €1,500 per seat |
| Procurement | Distributor portals | Purchasing | Usually free |
Note what is missing. Ireland has no domestic design platform with meaningful share, and no equivalent of the bundled compliance workflow tool that dominates the UK domestic market. Irish installers assemble their stack from international products, then bolt an internal process onto the grant layer. That gap is the defining feature of the market.
Several of these platforms price in dollars. At roughly 0.92 euro to the dollar, which is illustrative rather than a quote, a seat listed at $1,299 lands near €1,195 before tax, and it moves with the rate every renewal.
The Layer That Is Specific to Ireland
Grant administration is the Irish layer, and it is genuinely operational work rather than a form at the end.
Domestic grant-supported work runs through SEAI-registered contractors. Registration carries obligations, the customer’s grant depends on the paperwork being right, and the sequence of application, works, and post-works documentation has to be tracked per job. Electrical work follows I.S. 10101, the national wiring rules, with certification handled by a registered electrical contractor. Grid connection is notified to ESB Networks under NC6 for smaller installations or NC7 for larger ones.
None of that is a modelling problem. It is a tracking problem, and it is the single largest consumer of administrative hours in an Irish domestic solar business. A firm doing 200 grant jobs a year is running 200 parallel document trails with external deadlines attached. Miss a step and the customer’s grant is at risk, which converts an admin slip into a commercial dispute.
The practical consequence: in Ireland the CRM layer earns its licence earlier than the design layer does. Most markets buy design software first. Here, a pipeline tool that can hold a per-job document checklist and chase the missing item is worth more per euro at low volume than a better simulation engine.
Commercial and industrial rooftop work sits outside the domestic grant flow and looks like any other northern European market: a real simulation tool, a yield study with stated assumptions, and an NC7 process run by someone competent.

Why the Irish Sky Changes the Shading Argument
A large share of annual irradiance in Ireland arrives as diffuse light rather than direct beam. That single fact undercuts a sales argument used everywhere else.
A shading model that traces only the direct beam treats an obstruction as a hard on or off. Under a bright cloud deck, a panel partly hidden from the sun still receives light from most of the sky dome. So a beam-only model reports a loss that the array does not actually suffer, and the overstatement is larger here than in a clear-sky market. Quote from that model and you have overstated the problem.
Which leads to the opinionated part. In Ireland, module-level optimisers are sold far more often than the physics justifies. On a lightly shaded roof under a diffuse sky, the recovered energy is small, the hardware cost is real, and the payback frequently does not clear the extra spend across the system life. Optimisers earn their place on genuinely awkward roofs, on the north side of a close chimney, or where multiple orientations share a string. Fitting them by default is a habit, not an engineering decision.
The roof stock makes this live. Terraced and semi-detached housing puts chimneys and neighbour gables within metres of the array, and at this latitude those objects throw long shadows for months. The obstructions are real. The question is how much they actually cost, and only a model that separates diffuse from beam can answer it.
What Stack You Need at Your Size
Domestic installer, under 100 systems a year. Two layers. A design and proposal tool, plus whatever holds the grant document trail, even a disciplined spreadsheet. A dedicated simulation platform is not earning its licence yet.
Domestic installer, 100 to 400 systems a year. Three layers, and the CRM comes before the second design seat. At this volume the grant admin load is what breaks first.
Mixed domestic and commercial. Four layers. Commercial clients want a yield study with stated losses, and the domestic stack cannot produce one. This is the transition that catches Irish firms out.
Commercial and industrial rooftop. Five layers, with PVsyst or an equivalent as the engine of record and a documented NC7 process.
Pricing the Whole Stack in Euro
| Company stage | Layers | Realistic annual software spend |
|---|---|---|
| Domestic under 100 systems | 2 | €500 to €3,000 |
| Domestic 100 to 400 systems | 3 | €3,000 to €9,000 |
| Mixed domestic and commercial | 4 | €9,000 to €25,000 |
| Commercial and industrial | 5 plus | €25,000 upward |
Total addressable volume in Ireland is small compared with Britain or Germany. That argues against a per-seat-heavy stack. Four well-utilised seats beat 12 seats bought so nobody has to wait, because the fixed cost lands on a smaller revenue base. Buy fewer licences and schedule the work around them.

What Most Irish Installers Get Wrong
They buy design seats for the whole team and run the grant layer on email.
Here is the failure mechanism. An SEAI grant job has a required sequence with external deadlines, and the customer’s money depends on it. When that trail lives in a shared inbox, the state of each job exists only in someone’s head. A surveyor leaves, an installer is off sick, a post-works document sits unsent for three weeks, and nobody notices because there is no record showing the step is outstanding. The problem surfaces when the customer rings about the grant, which is the worst moment to discover it.
Meanwhile six people hold design licences and two of them open the software monthly. The spend went to the layer with the lowest failure cost and the busiest layer got nothing.
The fix is unglamorous. Put every grant job in a system with a per-job checklist and a visible outstanding state, cut design seats to the people who design daily, and route everyone else through them. That reallocation costs nothing net and removes the failure mode that actually damages customers.
When Software Is Not the Answer
If a commercial enquiry stalls because nobody can produce a layout, a yield study, and a compliant single-line diagram inside the week, that is engineering capacity rather than a software gap. Buying a licence does not create the hours or the reviewer.
Our solar rooftop detailed engineering design and solar 3D pre-design services cover exactly that, with sales-stage models turned around in 48 hours. See the sample design pack or talk to our team.
Conclusion
- The grant layer is where Irish jobs fail, so fund it first. It carries the highest failure cost and usually the smallest budget.
- Separate diffuse from beam before you sell an optimiser. Beam-only models overstate the loss under Irish skies.
- Buy fewer, better-utilised seats. A small market cannot carry a per-seat-heavy stack.

FAQ
What is solar software? An umbrella term for six categories: design and simulation, sales and proposal, compliance and grant documentation, monitoring, CRM and operations, and procurement. In Ireland the grant administration layer consumes the most staff hours.
What solar software do Irish installers actually use? Mostly international products. A design and proposal tool such as OpenSolar or SurgePV, PVsyst for commercial yield studies, a general CRM, and the inverter vendor’s monitoring portal. There is no dominant Irish domestic platform.
How much does solar software cost in Ireland? Roughly €500 to €3,000 a year for a small domestic installer, €9,000 to €25,000 for a mixed domestic and commercial business, and more above that.
Does SEAI require specific software? No. Grant-supported domestic work must be carried out by an SEAI-registered contractor with the required documentation, and the electrical work follows I.S. 10101. No product is mandated.
What is the difference between NC6 and NC7? Both are ESB Networks connection routes. NC6 covers smaller installations notified through the simpler process, and NC7 applies to larger connections that need a fuller application. Both are documentation processes, not modelling tasks.
Are optimisers worth it in Ireland? Sometimes, but far less often than they are sold. Under a diffuse sky the recovered energy on a lightly shaded roof is modest, so run the numbers on a model that separates diffuse from beam before quoting them as standard.
