Solar Panels for Bungalows in Ireland 2026: Why Single-Storey Homes Are Ideal for Solar

Bungalows have the biggest, simplest roofs in Ireland — and that makes them perfect for solar panels. Here is the complete guide to system sizing, costs, and savings for bungalow owners in 2026.

If you own a bungalow in Ireland, you are sitting on one of the best roof types in the country for solar panels. Bungalows typically have large, uninterrupted roof planes with fewer dormers, valleys, and obstructions than two-storey houses. That means more usable space, simpler installation, and lower costs per panel.

This guide covers everything a bungalow owner needs to know: how many panels you need, what it costs after the SEAI grant, how much you will save, and the specific advantages your roof shape gives you over other house types.

Why Bungalows Are Ideal for Solar

Not all roofs are created equal when it comes to solar. Here is why bungalows consistently outperform other house types:

In short, if you have a bungalow with a south, south-east, or south-west facing roof, you have an almost ideal setup for solar in Ireland.

How Many Panels Does a Bungalow Need?

The right system size depends on your electricity usage, not just your roof size. Here is a quick sizing guide based on typical bungalow households:

Bungalow Type	Annual Usage	Recommended System	Panels Needed
Small bungalow (1–2 bed)	3,000–3,500 kWh	3.1 kWp	7 panels
Medium bungalow (3 bed)	4,000–5,000 kWh	4.4 kWp	10 panels
Large bungalow (4–5 bed)	5,500–7,000 kWh	6.2 kWp	14 panels
Large bungalow + EV	7,000–9,000 kWh	8.0 kWp	18 panels

A key advantage for bungalows: because you have more roof space than a typical semi-d, you can often go bigger than the minimum recommended system. A larger system means more electricity exported to the grid under the Clean Export Guarantee, earning you 24c/kWh from your supplier.

Each modern panel (2026 N-type TOPCon standard) produces around 440W and measures approximately 1.9 m². So 10 panels need about 19–21 m² of roof space — well within what most bungalows offer on a single roof face.

Full Cost Breakdown (After SEAI Grant)

Solar panel costs in Ireland have stabilised in 2026 thanks to 0% VAT and mature supply chains. Here is what bungalow owners can expect to pay:

System Size	Panels	Cost Before Grant	SEAI Grant	Net Cost
3.1 kWp	7	€5,800–€6,500	€1,600	€4,200–€4,900
4.4 kWp	10	€7,300–€8,500	€1,800	€5,500–€6,700
6.2 kWp	14	€9,800–€11,200	€1,800	€8,000–€9,400
8.0 kWp	18	€12,500–€14,000	€1,800	€10,700–€12,200

How the SEAI grant works: You receive €700 per kWp for the first 2 kWp, and €200 per kWp for capacity between 2–4 kWp. The maximum grant is €1,800 for systems of 4 kWp or larger. Your home must have been built and occupied before 2021.

Bungalows often come in slightly cheaper than two-storey houses because the scaffolding requirements are simpler and the roof is easier to work on. Expect to save €300–€500 on installation labour compared to a similar-sized system on a two-storey house.

Bungalow Roof Types and Solar Compatibility

Irish bungalows come in several roof styles. Here is how each one works with solar panels:

Realistic Savings for Bungalow Owners

How much you save depends on three things: your system size, how much electricity you use during daylight hours, and whether you export surplus to the grid. Here are realistic 2026 figures:

System	Annual Generation	Self-Use Savings	Export Income	Total Savings/yr	Payback
3.1 kWp (7 panels)	2,800 kWh	€520	€160	€680	6–7 yrs
4.4 kWp (10 panels)	3,950 kWh	€700	€280	€980	5–7 yrs
6.2 kWp (14 panels)	5,550 kWh	€880	€420	€1,300	6–7 yrs
8.0 kWp (18 panels)	7,200 kWh	€1,050	€600	€1,650	6–7 yrs

Note: Self-use savings assume 38c/kWh average electricity rate (typical mid-2026 unit rate). Export income assumes 24c/kWh under the Clean Export Guarantee. Bungalow owners who work from home or are retired tend to have higher self-use ratios (40–50% vs the typical 30–35%), which improves payback.

Many bungalow owners are retirees who are home during the day — this is a significant advantage. Being home when the sun shines means you use more of your own solar electricity directly, which is worth 38c/kWh rather than the 24c/kWh you get for exporting it.

Should You Add a Battery or Diverter?

Once you have solar panels generating electricity, you have two options for dealing with surplus power beyond exporting it to the grid:

Solar Immersion Diverter (€450–€640 installed)

A solar diverter sends surplus electricity to your immersion heater, giving you free hot water from March to October. This is the cheapest add-on and pays for itself in 1–2 years. Popular brands include the myenergi Eddi (€400–€500) and iBoost (€300–€400).

Best for: Bungalow owners with a hot water cylinder who want a quick, low-cost upgrade.

Battery Storage (€2,500–€6,000 installed)

A solar battery stores surplus electricity for use in the evening and at night. A 5 kWh battery costs €2,500–€3,500 installed. Batteries make the most sense for larger systems (6+ kWp) where you are exporting a lot of power.

Best for: Bungalow owners with larger systems who want to maximise self-consumption and reduce grid dependence.

Our recommendation for most bungalow owners: Start with panels + diverter. Add a battery later if your electricity bills still seem high in the evenings. Battery prices are expected to continue falling through 2026–2027.

Planning Permission for Bungalows

Good news: most bungalow solar installations do not require planning permission. Under current exempted development rules:

• Roof-mounted panels on a house are exempt from planning permission
• Panels must not project more than 15 cm above the roof surface
• Panels must be at least 50 cm from the edge of the roof
• The total area of panels must not exceed 12 m² or 50% of the total roof area (whichever is greater) — this generous limit means bungalows rarely hit the cap
• If your bungalow is in an Architectural Conservation Area or is a protected structure, you will need planning permission

Your installer will confirm whether your specific property qualifies for the exemption as part of the survey.

How to Get Started

Here is the step-by-step process for getting solar panels on your bungalow:

1. Get 3 quotes. Request free quotes from SEAI-registered installers. They will do a site survey and assess your roof.
2. Compare quotes carefully. Look at panel brand, inverter type, warranty length, and total installed price. Our guide to choosing an installer walks you through what to look for.
3. Apply for the SEAI grant. Your installer typically handles this for you. The grant is paid directly to the installer, so you only pay the net cost. Read our step-by-step SEAI grant guide.
4. Installation takes 1–2 days. A typical bungalow installation is faster than a two-storey house — many are completed in a single day for systems up to 10 panels.
5. Register for the Clean Export Guarantee. Contact your electricity supplier to sign up and start earning from exported power.

The Bottom Line

Bungalows are among the best house types in Ireland for solar panels. You have the roof space, the access is easy, and the costs are slightly lower than for two-storey homes. Whether you are a retiree looking to cut bills, a young family in a rural bungalow, or anyone in between — the numbers work.

• 10 panels (4.4 kWp) suits the average 3-bed bungalow — from €5,500 after the SEAI grant
• €980 saved per year on a typical installation
• 5–7 year payback, then 20+ years of near-free electricity
• No planning permission needed for most installations
• Add a diverter for free hot water — just €450–€640 extra
