How to Read a Solar Quote Ireland 2026: The 7 Line Items Every Installer Should Show

You’ve got three solar quotes on the kitchen table. One is €9,400. One is €11,200. One is €13,800. They’re all “4 kW systems with a 5 kWh battery.” They all promise SEAI-registered installers, tier-one panels, 25-year warranties.

How do you actually tell which one is honest? And which one is either padded or missing something you’ll get billed for later?

This guide is the checklist we wish every Irish homeowner had before they signed a solar contract in 2026. It’s built from real quote data (118 installs completed Jan–July 2026), the questions SEAI-registered installers themselves say separate a good quote from a bad one, and the seven line items you should insist on seeing broken out.

The 30-second summary

A comparable solar quote in Ireland in 2026 breaks the total into seven line items: panels, inverter, mounts & DC wiring, scaffolding, labour, paperwork & sign-off, and installer margin. If your quote is a single number with a spec sheet and nothing else, it’s not comparable — ask the installer to itemise before you sign anything.

The seven line items every solar quote should show

Here’s the middle-of-market spend for each component on a standard 11-panel (4.4 kWp) install in 2026, drawn from the 118 quotes we tracked:

Line item	2026 range (11-panel job)	What you’re paying for
1. Panels	€2,050–€2,700	11 × Jinko Tiger Neo 480W / AIKO Comet 3S 475W / LONGi 470W
2. Inverter	€1,550–€2,400	SolaX X1-Hybrid / SolarEdge SE5000H / Sungrow SH5.0RS
3. Mounts, cabling, DC/AC isolators, surge	€1,050–€1,500	Van der Valk / K2 rails, MC4 connectors, 10 mm2 DC, RCBO, DC + AC surge
4. Scaffolding	€350–€600	Two-storey semi-detached, 1–2 days on hire
5. Labour	€1,700–€2,400	Two installers, 1.5–2 days on-site (including electrician)
6. Paperwork & sign-off	€700–€1,050	SEAI grant admin, ESB Networks NC6, completion cert, RECI/Safe Electric
7. Installer margin & warranty reserve	€900–€1,600	The bit that keeps them in business & funds warranty callouts
All-in before grant	€10,850 avg	Minus €1,800 SEAI = €9,050 after grant

These are honest 2026 numbers for a standard install — not the “from” prices in Facebook ads and not the top-tier packages loaded with Powerwalls and premium racks.

How to actually compare three quotes

Do this literally: put the three quotes side by side on paper and fill in a comparison grid. Every quote that can’t populate a cell is a quote hiding something.

Question	What a good answer looks like
Panel model & exact wattage?	“Jinko JKM480N-60HL4-V, 480W” — brand, model number, watts. Not “450W tier-one panels.”
Inverter model & whether it’s hybrid?	“SolaX X1-Hybrid G4 5kW” — hybrid means battery-ready. Non-hybrid means adding a battery later needs a second inverter.
DC surge protection included?	Yes, Type 2 SPD on the DC side. Ireland gets a lot of storms; this is basically mandatory now.
Is scaffolding included or a separate cost?	Included, itemised. Not “subject to site survey” or “paid separately.”
Who signs the completion cert?	A named RECI or Safe Electric electrician. Not “our team.”
Grant handled by installer or by you?	Installer applies for and receives the SEAI €1,800 grant on your behalf, deducted at invoice.
Warranty terms: panels, inverter, workmanship?	Panels 25–30 yr product / 30 yr performance. Inverter 10–12 yr. Installer workmanship 5+ yr.
Estimated annual output (kWh)?	A single figure with the assumptions (roof pitch, orientation, shading). Not a range from a brochure.

Red flags a quote is padded

Watch for these in the “too high” direction:

• Total after grant more than €10,500 for an 11-panel PV-only system on a standard two-storey house
• Battery add-on quoted above €4,500 for a 5 kWh unit fitted alongside a new PV install (Pylontech / BYD 5.12 kWh should be €3,400–€3,900 fitted in 2026)
• Scaffolding line above €600 for a two-storey semi-detached (rural spikes to €700+ are legitimate)
• “Premium monitoring subscription” bundled as compulsory — the SolarEdge, Enphase, SolaX and Sungrow apps are free. Anyone charging €10/month for basic monitoring is padding.
• “Optional” upgrades presented as required — e.g., €800 for a smart consumer unit that’s already in your fuse box, or a €500 “PV isolator upgrade” that’s already in the inverter
• “3-year electricity contract” bundled with the install — this is a supplier commission dressed as a discount. It usually costs you more over three years than the saving.

Red flags a quote is too low

Watch for these in the “too cheap” direction:

• String inverter for a partly-shaded roof — if any part of your roof gets shaded by a chimney, dormer or tree, you need optimisers (SolarEdge) or microinverters (Enphase). Both cost €600–€1,200 more than a string.
• No DC surge protection mentioned — a €90 component that saves €2,500 in inverter replacement after a lightning strike. If it’s not on the quote, ask why.
• No electrician sign-off line — someone has to write the RECI/Safe Electric completion cert. If it’s not billed, either the installer is doing it themselves (they may not be certified to) or you’ll get billed separately at completion.
• Panels named vaguely — “450W tier-one panels” without a brand means the installer wants flexibility to substitute whichever bulk pallet is cheapest that week. Insist on the exact model number for warranty purposes.
• Vague inverter — “5kW hybrid inverter” without a brand/model tells you nothing about warranty length or app quality.
• “Scaffolding subject to site survey” — this is a get-out clause. A real quote for a two-storey semi in Dublin doesn’t need a site survey to price scaffolding within €150.

What good quotes look like: three real 2026 examples

Three real quotes we tracked (anonymised installer names). Same house: standard two-storey semi in south Dublin, south-facing pitch with mild afternoon shade from a mature ash tree.

Component	Installer A	Installer B	Installer C
Panels	11 × Jinko 480W	11 × AIKO 475W	10 × “tier-one 450W”
Inverter	SolarEdge SE5000H + optimisers	SolaX X1-Hybrid G4 5kW	“5kW hybrid inverter”
Shading solution	Yes (per-panel optimisers)	Yes (2-string design)	Not mentioned
DC surge	Included	Included	€280 extra
Scaffolding	€480 itemised	€520 itemised	“Subject to survey”
Grant handled	Yes, deducted at invoice	Yes, deducted at invoice	“You apply, we assist”
Total after grant	€10,650	€9,200	€7,900 (then +€850 at completion)

Installer C is the “cheapest” on paper but the vague spec, missing shading solution, extra DC-surge charge, unpriced scaffolding and homeowner-does-the-grant workload almost always mean higher total spend, more admin, and a system that won’t perform as well through summer afternoons. Installer B is the honest sweet spot. Installer A is a legitimate premium option (SolarEdge is nice, per-panel monitoring is nice, but you pay €1,450 more for the privilege).

Questions to ask on the phone before the site survey

Save yourself a wasted afternoon: three quick screening questions before you agree to an in-home visit.

1. “Are you an SEAI-registered PV contractor?” If no, walk away — the €1,800 grant is only available on SEAI-registered installs.
2. “Which panel and inverter brand would you likely propose for a standard 11-panel install?” Good installers name specific brands they stock. Vague answers (“tier-one, top quality”) suggest a sales-first, technical-second outfit.
3. “Roughly, what does an 11-panel PV-only install cost in my county, after grant?” Anyone who won’t give a ballpark (€8,500–€10,500 for most counties in 2026) either doesn’t know their own pricing or plans to price on the day.

What to check on the day the installer arrives

• Panels arriving match the model on the quote (photo the pallet label before it’s unwrapped)
• Inverter model matches the quote (photo the serial plate)
• DC surge protection unit is actually fitted next to the inverter
• All roof penetrations sealed and cabled through weatherproof grommets, not silicone-only
• Isolator switch fitted and labelled at the AC side (mandatory for firefighter safety)
• You get: SEAI completion pack, electrician cert, panel & inverter warranty certs, and app login credentials before the installer leaves

If any of these are missing or vague, don’t sign the completion paperwork until they’re resolved. Once you’ve signed, the leverage flips to the installer.

Bottom line

A comparable Irish solar quote in 2026 is a quote you can put on paper next to two others and fill in a seven-line grid. If it’s a single price with a spec sheet and a “trust us,” it’s not comparable and it’s not the quote you should sign.

The middle of the market for a standard 4.4 kWp PV-only install is €9,050 after grant. Add a 5 kWh battery and you’re at €13,600 after grant. Two quotes within 10% of each other in the middle of that range, both fully itemised, is a competitive market working properly. Take the one whose installer answered your questions the clearest — not necessarily the cheapest.
