Solar PV

What is solar? 101

What it is

Panels that turn daylight into electricity — even on cloudy Irish days.

Tap to learn more

What it is

  • Solar PV (photovoltaic) panels convert daylight into DC electricity.
  • The inverter turns that DC into AC electricity your home can use.
  • Works in overcast Irish weather — just produces less than bright sunshine.
  • Panels last 25–30 years with minimal maintenance.
  • A typical 4 kWp system (~10 panels) generates ~3,600 kWh per year in Ireland.

How you save

Use your own power first. Sell the rest to the grid.

Tap to learn more

How you save

  • Self-consumption: solar powers your appliances in real time.
  • Without a battery, roughly 30–40% of what you generate is used directly.
  • Surplus electricity goes to the grid at your export rate (around €0.20/kWh).
  • The more you shift usage to daylight hours, the more you save.
  • With a battery, self-consumption jumps to 70–85%.

What it costs

~€8,000–€10,000 before grant for a 4 kWp system.

Tap to learn more

What it costs

  • Basic 4 kWp solar PV install: €8,000–€10,000 before SEAI grant.
  • SEAI grant: up to €1,800 for panels 2 kWp and above.
  • After grant, a basic install is roughly €6,200–€8,200.
  • Payback is typically 8–12 years depending on your usage pattern.
  • 25-year lifetime savings can be €15,000–€25,000+ with inflation.

Does it suit your house?

South-facing roof is ideal. East or west still work well.

Tap to learn more

Does it suit your house?

  • South-facing roof at 30–35° pitch catches the most daylight.
  • East and west-facing roofs still work — they just produce more in morning/evening.
  • North-facing roofs are usually not worth it in Ireland.
  • You need roughly 20–25 m² of unshaded roof space for a 4 kWp system.
  • Shading from trees or chimneys matters — we check this on survey.

Battery Storage

What is a battery? 101

What it is

A box that stores daytime solar for use in the evening.

Tap to learn more

What it is

  • A home battery stores excess solar electricity during the day.
  • You discharge it in the evening when solar is not producing.
  • Typical sizes: 5 kWh, 8 kWh, or 10 kWh — we match to your usage.
  • The battery connects to a hybrid inverter (solar + battery combined).
  • Modern lithium batteries last 10–15 years with a warranty.

The difference it makes

Without: 30–40% self-use. With: 70–85%.

Tap to learn more

The difference it makes

  • Without a battery, most solar surplus goes to the grid cheaply.
  • You only use 30–40% of what you generate during daylight hours.
  • With a 5–10 kWh battery, self-consumption jumps to 70–85%.
  • That means far less buying electricity from the grid at night.
  • Batteries also provide a small buffer during power cuts (not full backup).

What it costs

Adds €4,000–€7,000. Payback 8–12 years.

Tap to learn more

What it costs

  • A 5–10 kWh battery adds roughly €4,000–€7,000 to your install.
  • There is no separate SEAI grant for batteries — it comes under solar PV.
  • Payback is longer than solar alone: typically 8–12 years.
  • Worth it if you work from home, have an EV, or want energy independence.
  • Hybrid inverters are battery-ready — you can add a battery later.

Does it suit you?

Best for EV owners, WFH households, or high evening usage.

Tap to learn more

Does it suit you?

  • Great fit if you have an EV — charge it from stored solar in the evening.
  • Ideal for work-from-home households with high daytime + evening usage.
  • If you are out all day and home all evening, a battery is a strong match.
  • If your usage is mostly during daylight, solar alone may be enough.
  • We model your actual usage pattern before recommending a battery.

Heat Pumps

What is a heat pump? 101

What it is

An electric system that heats your home and water — replaces oil or gas.

Tap to learn more

What it is

  • A heat pump extracts heat from outdoor air and amplifies it for your home.
  • It runs on electricity, so no more oil or gas deliveries.
  • It heats radiators, underfloor heating, and your hot water cylinder.
  • Works like a fridge in reverse — very efficient at low temperatures.
  • The outdoor unit sits outside; an indoor unit connects to your heating system.
Tap to flip back

How it saves

3–4 units of heat for every 1 unit of electricity.

Tap to learn more

How it saves

  • Heat pumps are 300–400% efficient — 3–4 kWh of heat per 1 kWh of electricity.
  • That makes them far cheaper to run than oil or gas boilers long term.
  • Your heating bill drops, especially as oil and gas prices rise.
  • Pairs well with solar PV — your panels can power the pump during the day.
  • Lower carbon footprint too — no fossil fuel combustion in your home.

SEAI grant

Up to €6,500 — the largest single home energy grant.

Tap to learn more

SEAI grant

  • The SEAI heat pump grant is up to €6,500.
  • You must use an SEAI-registered installer and get a technical assessment.
  • Your home must meet minimum insulation standards before install.
  • The grant is deducted from your invoice — no claiming back.
  • Check current rates at seai.ie/grants — amounts can change.

Does it suit your house?

Needs decent insulation. Check BER first.

Tap to learn more

Does it suit your house?

  • Heat pumps work at lower temperatures than boilers.
  • That means your home must be well insulated to feel warm.
  • If your BER is poor, insulation upgrades may be needed first.
  • Larger radiators or underfloor heating help a heat pump perform best.
  • We assess your BER, insulation, and heating system before recommending.

Insulation

What is insulation? 101

What it is

Stopping heat from escaping your walls, roof, and floors.

Tap to learn more

What it is

  • Insulation slows heat loss so your home stays warm with less energy.
  • Attic insulation: the quickest win — heat rises and escapes through the roof.
  • Cavity wall insulation fills the gap in double-brick walls.
  • External wall insulation wraps the outside of solid walls.
  • The better the insulation, the lower your heating bills and the warmer you feel.

The types

Attic, cavity wall, and external — each with different grants.

Tap to learn more

The types

  • Attic insulation: €300–€1,500 SEAI grant. Quick install, immediate effect.
  • Cavity wall insulation: €700–€1,700 SEAI grant. Suitable for homes with cavity walls.
  • External wall insulation: €3,000–€8,000+ SEAI grant. For solid or non-cavity walls.
  • Heating controls: up to €700 grant for thermostats and zoning.
  • One Stop Shop: wraps insulation, heat pump, and controls into one retrofit.

Why it comes first

Insulation before solar or heat pump. Otherwise you are wasting money.

Tap to learn more

Why it comes first

  • A heat pump will not work well in a draughty, poorly insulated home.
  • Solar savings are reduced if you are leaking heat everywhere.
  • Insulation is the foundation — it makes everything else perform better.
  • Better insulation improves your BER rating, unlocking higher grants.
  • We always assess insulation levels before recommending solar or heat pumps.
