Solar Panels for Nursing Homes in Ireland
Nursing homes are one of the strongest cases for commercial solar in Ireland. Care facilities run 24/7, with constant demand from space heating, hot water, laundry, catering kitchens, lighting and medical equipment. That steady daytime base load means a solar array is mostly self-consumed rather than exported. With the SEAI Non-Domestic Microgeneration Grant plus the Accelerated Capital Allowance, and a sector running on tight margins, solar delivers stable energy costs and a useful resilience angle.

Quick Answer
Most Irish nursing homes install 20-150 kWp of rooftop solar, sized to a constant 24/7 load from heating, hot water, laundry, kitchens and medical equipment. A typical 50 kWp system costs roughly €45,000-€55,000 before grant, can fall by around €12,000 with the SEAI Non-Domestic Microgeneration Grant, and qualifies for the Accelerated Capital Allowance. With strong daytime base load and year-round demand, payback is typically 5-7 years.
Why solar suits nursing homes
A nursing home has the ideal demand profile for solar PV: a large, steady electrical load that runs all day, every day of the year. Unlike an office that empties at 5pm or a school that closes for summer, a care facility never switches off. Heating, hot water, laundry, the catering kitchen, lighting and medical equipment draw power around the clock. That constant base load means a well-sized array is almost entirely self-consumed rather than exported, and self-consumption is where the savings are.
The year-round nature of the load is the key. Many commercial buildings have a summer dip, but a nursing home runs at high demand in every season, with strong daytime usage that lines up closely with when panels generate. Laundry cycles, kitchen prep, hot-water reheating and daytime care activity all fall in daylight hours, so the midday solar peak displaces expensive import rather than spilling to the grid.
Roof space is rarely the constraint. Care homes are typically built on large flat or pitched roofs with plenty of unshaded area, far more than the array needs, which means you can size the system to the load rather than to the available space. Solar also adds a resilience and energy-cost-stability story that matters in a sector where margins are tight and budgets are planned years ahead. For the wider picture across building types, see our commercial solar guide.
Heating & hot water
Space heating and constant hot water for washing, bathing and sanitation are a year-round load that solar offsets directly during daylight hours.
Laundry & kitchens
Industrial laundry and catering kitchens run heavy daytime cycles, steady loads that solar covers well and that rarely pause at weekends.
Lighting & equipment
Lighting, medical equipment and call systems run 24/7. A battery can shift surplus midday generation into the evening and overnight care load.
What size solar system does a nursing home need?
Most Irish nursing homes install between 20 and 150 kWp. Bed count is the simplest guide to sizing, since the constant load scales roughly with the number of residents and the catering, laundry and heating that supports them. A small home of 30–40 beds often suits 20–40 kWp, while a large 150-bed facility can justify 100–150 kWp. Because the base load is so steady, you can size confidently toward the daytime demand under the Non-Domestic Microgen Grant rather than worrying about export.
| Bed Count | Typical System | Panels (approx.) | Annual Generation | Best Grant Route |
|---|---|---|---|---|
| Up to 40 beds | 20–40 kWp | 46–92 | ~17,000–34,000 kWh | NDMG + ACA |
| 40–70 beds | 40–60 kWp | 92–138 | ~34,000–52,000 kWh | NDMG + ACA |
| 70–110 beds | 60–100 kWp | 138–230 | ~52,000–86,000 kWh | NDMG + ACA |
| 110–150+ beds | 100–150 kWp | 230–345 | ~86,000–129,000 kWh | NDMG + ACA |
Generation assumes the average Irish yield of around 860 kWh per kWp per year. Actual figures depend on roof pitch, orientation and shading. A site survey and a year of half-hourly meter data give the accurate sizing, since the goal is to match your constant base load rather than to oversize and export cheap surplus.
Nursing home solar grants, ACA and payback
For nursing homes the headline grant is the SEAI Non-Domestic Microgeneration Grant (NDMG). The NDMG funds commercial rooftop solar on a per-kWp basis, up to a maximum of €162,600 on large systems, and care facilities are not agricultural so the TAMS farm scheme does not apply. The grant stacks with the Clean Export Guarantee for any surplus you export, though with a 24/7 base load most generation is self-consumed.
On top of the grant, nursing homes trading as a company can claim the Accelerated Capital Allowance (ACA), which writes off 100% of qualifying solar cost against profits in year one. Combined, the NDMG and ACA pull the effective cost down sharply and shorten payback to around 5–7 years for a sector that benefits from locking in stable, predictable energy costs.
| System | Gross Cost (est.) | Grant Route | Net Cost (est.) | Payback |
|---|---|---|---|---|
| 20 kWp | €18,000–€22,000 | NDMG (€6,000) | €12,000–€16,000 | 5–7 years |
| 50 kWp | €45,000–€55,000 | NDMG (€12,000) | €33,000–€43,000 | 5–7 years |
| 100 kWp | €80,000–€100,000 | NDMG (€22,000) | €58,000–€78,000 | 5–7 years |
| 150 kWp | €120,000–€150,000 | NDMG (€32,000) | €88,000–€118,000 | 6–8 years |
Installed cost on care buildings runs roughly €800–€1,000 per kWp at commercial scale, with smaller systems at the higher end per kWp. Figures are estimates for 2026 and exclude battery storage, which is not covered by NDMG.
Accelerated Capital Allowance
Nursing homes trading as a company can claim the Accelerated Capital Allowance (ACA), writing off 100% of qualifying solar and battery cost against profits in year one through the Triple-E register. This is a meaningful sweetener for a sector managing tight operating margins, and your accountant can confirm how it applies to your structure.
Where the savings come from
Commercial electricity costs around 22c/kWh to import while exported surplus earns roughly 18c/kWh, so displacing your own 24/7 load is worth more than exporting. Nursing homes with a constant base load reach 85–95% self-consumption, which is why the returns are strong and the energy bill becomes far more predictable year to year.
Roof, planning and install specifics for nursing homes
The practical details on a care facility differ from a farm or a warehouse. Plan for these before you commit to a system size.
| Factor | What to check on a nursing home |
|---|---|
| Roof structure | Care homes often have flat or low-pitch roofs; an installer should confirm the structure carries ballasted or fixed mounting load and that waterproofing is not compromised. |
| Resilience & backup | Continuity of power matters where residents rely on medical equipment; solar with battery storage can support a backup strategy alongside any existing generator. |
| Load matching | The 24/7 base load is steady, so most generation is self-consumed; a battery shifts midday surplus into the evening and overnight care load to lift self-consumption further. |
| Grid connection | ESB Networks NC6 covers smaller systems and NC7 covers larger ones up to 200kW; inverters must meet EN 50549. |
| Disruption | Installation should be staged to avoid disturbing residents; flat-roof work and limited daytime noise windows are usually straightforward to plan around. |
Battery for resilience and overnight load?
Because a nursing home runs heavily into the evening and through the night, surplus midday generation has an obvious home. A battery stores noon production and releases it into the overnight care load, lifting self-consumption toward the top of the range. It also supports a resilience strategy, holding critical circuits during a grid outage alongside any standby generator. Whether the numbers justify a battery depends on your tariff and night-time demand.
Nursing Home Solar FAQ
How big a solar system does a nursing home need?
Most Irish nursing homes install 20-150 kWp, sized by bed count and the constant 24/7 load from heating, hot water, laundry, kitchens and medical equipment. A 30-40 bed home often suits 20-40 kWp, while a large 150-bed facility can justify 100-150 kWp. Because the base load is steady year-round, sizing should match daytime demand, ideally using a year of half-hourly meter data.
What grant can a nursing home get for solar panels?
The headline grant for nursing homes is the SEAI Non-Domestic Microgeneration Grant (NDMG), which funds commercial rooftop solar on a per-kWp basis up to a maximum of €162,600. Nursing homes are not agricultural, so the TAMS farm scheme does not apply. Companies can also claim the Accelerated Capital Allowance (ACA) to write off 100% of qualifying cost against profits in year one.
Why are nursing homes such a good fit for solar?
Nursing homes run 24/7 with a constant load from heating, hot water, laundry, catering kitchens, lighting and medical equipment, and that demand stays high year-round. The steady daytime base load lines up closely with when panels generate, so 85-95% of generation is self-consumed rather than exported. That high self-consumption is what drives strong returns and predictable energy costs.
Can solar provide backup power for a nursing home?
Solar paired with battery storage can support a resilience strategy, holding critical circuits such as medical equipment and lighting during a grid outage alongside any existing standby generator. Solar alone does not provide backup, but a battery stores midday surplus and can release it into the evening and overnight care load, which also lifts self-consumption.
What is the payback on solar panels for a nursing home?
A 50 kWp system costs roughly €45,000-€55,000 before grant and around €33,000-€43,000 after the SEAI NDMG, with the Accelerated Capital Allowance shortening it further for companies. Typical payback is 5-7 years. Payback is driven by self-consumption, since displacing import at about 22c/kWh is worth more than exporting surplus at about 18c/kWh, and a 24/7 load means almost all generation is used on site.
