Solar Panels for Care Homes
Reduce energy costs, achieve net zero commitments and protect against rising electricity prices with a tailored solar PV system designed for 24/7 care home operation.
Why Care Homes Are Ideal for Commercial Solar
Care homes operate 24 hours a day, 365 days a year — making them one of the most energy-intensive commercial property types in the UK. Heating, ventilation, laundry, commercial catering, hot water, medical equipment and continuous lighting create a base load that rarely drops below 15–20kW even at night. This consistent demand profile makes solar panels exceptionally effective: unlike offices that close at 5pm, a care home generates and uses solar electricity throughout every daylight hour.
The CQC and local authority contract frameworks have put intense pressure on care home operators to reduce operating costs. Energy bills are the second-largest overhead after staff costs for most residential care facilities. A well-designed solar system cuts electricity spend by 40–70% during daylight hours, releasing capital that can be reinvested in staffing, activities and fabric improvements.
Sustainability credentials are increasingly important in care sector procurement. Local authorities and NHS-funded placements increasingly favour providers with demonstrable ESG commitments. A solar installation provides tangible evidence of environmental responsibility while generating a strong financial return.
Care Home Energy Use: What Solar Covers
Understanding how a care home uses energy is the starting point for system design. The typical breakdown is:
| Energy Use | % of Total Bill | Solar Coverage Potential | Annual Value at 28p/kWh |
|---|---|---|---|
| Space heating & HVAC | 35–40% | High (daytime demand dominant) | £12,000–£20,000 |
| Domestic hot water | 20–25% | High (cylinder heating 8am–4pm) | £8,000–£12,000 |
| Laundry & linen | 12–18% | Very High (morning shift activity) | £5,000–£8,000 |
| Catering & kitchen | 10–14% | High (three meal services) | £4,000–£7,000 |
| Lighting | 8–12% | Medium (partial daytime only) | £3,000–£5,000 |
| Medical & ancillary | 4–8% | Low (distributed, 24/7) | £1,500–£3,000 |
Laundry is particularly valuable to offset. A care home washing and drying bed linen, towels and resident clothing for 50 residents can use 20,000–30,000 kWh per year on laundry alone. Scheduling wash runs during peak solar hours — typically 9am to 3pm — maximises self-consumption and reduces cost per cycle significantly.

The right system size depends on bed count, care type, building orientation and roof area. Our surveyors use half-hourly consumption data from your smart meter (or estimated profiles where unavailable) to match generation to your actual load curve.
| Facility Type | Bed Count | Typical System Size | Est. Annual Generation | Estimated Annual Saving |
|---|---|---|---|---|
| Residential Care Home | 20–30 beds | 50–75kW | 45,000–67,500 kWh | £12,000–£18,000 |
| Nursing Home | 40–60 beds | 75–120kW | 67,500–108,000 kWh | £18,000–£28,000 |
| Large Care Home | 80–100 beds | 120–200kW | 108,000–180,000 kWh | £28,000–£48,000 |
| Care Home Campus | 150+ beds | 200–500kW | 180,000–450,000 kWh | £48,000–£120,000 |
| NHS / LA Care Complex | Varies | 250kW–1MW+ | 225,000 kWh+ | £60,000–£250,000+ |
Ground-mounted systems are available where roof area is limited or structurally unsuitable — care homes with gardens, car parks or adjacent land can often site arrays externally with cable runs back to the main distribution board.
Battery Storage: Extending Coverage into Evening Hours
Care homes have significant evening demand that solar generation alone cannot cover. Adding lithium iron phosphate (LFP) battery storage allows energy generated during the day to be discharged after sunset, typically covering 6pm–midnight loads at a fraction of grid import cost.
A 100kWh BESS paired with a 150kW solar array at a 60-bed nursing home will typically cover 65–75% of total daily electricity consumption. The battery charges from surplus solar during the afternoon and discharges during the evening shift, providing hot water, corridor lighting and ancillary power from stored solar.
With Octopus Agile, Intelligent Octopus or similar time-of-use tariffs, the battery can also charge from the grid during off-peak windows (typically 12am–5am at under 10p/kWh) and discharge during peak periods (4pm–7pm at 28–35p/kWh), creating additional arbitrage savings on top of self-consumption.
Finance and Grants for Care Home Solar
Annual Investment Allowance (AIA)
Solar panels installed on a care home qualify for 100% first-year capital allowances under the Annual Investment Allowance, up to £1 million per year. A £100,000 system installation generates a £25,000 corporation tax deduction for a company paying 25% CT — effectively reducing the net cost to £75,000.
Salix Finance (NHS and LA-Operated Facilities)
Care homes operated by NHS trusts or local authorities can access Salix Finance interest-free loans. Salix's Social Housing Decarbonisation Fund and Public Sector Decarbonisation Scheme have together funded thousands of solar installations at public sector buildings since 2020. Loan repayments are typically structured to be fully covered by energy savings.
Smart Export Guarantee (SEG)
Any surplus solar electricity exported to the grid earns payment under the Smart Export Guarantee. Export rates from major suppliers currently range from 4p to 15p/kWh. A 150kW system at a busy care home might export 15,000–25,000 kWh per year, worth £600–£3,750 annually in SEG payments.
VAT Relief
Solar installations at charitable care homes may qualify for 0% VAT under relief for charity buildings. Non-charitable care homes pay 20% VAT on installation, but the system is a capital expense qualifying for AIA, offsetting most of the VAT cost.

From April 2027, all commercial buildings let under a new or renewed lease must achieve EPC Band C or better. Many older care homes with oil-fired boilers, poor insulation and outdated lighting are currently rated E or F. Solar PV — combined with LED retrofits and heat pump hot water systems — can raise an EPC rating by one or two bands, bringing facilities into MEES compliance and protecting future lease renewability.
Beyond MEES, corporate care groups listed or reporting under SECR (Streamlined Energy and Carbon Reporting) must disclose energy intensity and emissions. Solar generation displaces grid electricity (typically 200–220g CO2/kWh), directly reducing Scope 2 emissions disclosed in annual reports.

Frequently Asked Questions
How much does solar cost for a care home?
A 100kW system for a 50-bed care home typically costs £60,000–£80,000 installed. With current electricity prices around 28p/kWh, annual savings are usually £18,000–£28,000, giving a payback period of 5–7 years.
What size solar system does a care home need?
Most care homes need 50–200kW depending on bed count and services. A 30-bed home typically needs 50–75kW; a 100-bed facility with laundry and full catering needs 150–250kW.
Can care homes get solar grants?
Privately-owned care homes can claim 100% first-year capital allowances under AIA (up to £1 million). NHS-run facilities may access Salix Finance 0% interest loans. The Smart Export Guarantee pays for surplus electricity exported to the grid.
Does solar work with a care home running 24/7?
Yes — and 24/7 operation is actually ideal for solar. Care homes have consistent daytime loads (HVAC, laundry, catering, hot water) that match solar generation hours. Adding battery storage extends coverage into evening hours.
How long does a care home solar installation take?
A 100–150kW system takes 3–5 days to install with minimal disruption. We work around care home routines, ensuring residents and staff are unaffected. DNO notification is handled by our team.
What is the ROI for solar in a care home?
Most care homes see a 12–18% annual return on investment, with full payback in 5–8 years. The system then generates free electricity for the remaining 17–20 years of its 25-year design life.

Beyond the financial case, solar installation creates tangible benefits for care home compliance and quality ratings. The Care Quality Commission (CQC) 'Well-led' domain specifically assesses whether services are well-managed and sustainable. Demonstrating a structured approach to energy cost management — including renewable generation — signals strong governance to CQC inspectors.
Local authority commissioning teams, who place NHS-funded residents with care providers, increasingly request ESG and sustainability information as part of their due diligence process. A care home with solar panels, documented carbon reduction and a published sustainability plan demonstrates a long-term, well-managed approach to operations that can differentiate bids in a competitive commissioning environment.
Solar and the Social Value Act
The Public Services (Social Value) Act 2012 requires public sector commissioners to consider social, environmental and economic value in procurement. For care homes bidding for NHS Continuing Healthcare placements or local authority-funded residential care contracts, demonstrating reduced carbon footprint via solar installation can contribute to higher social value scores in procurement assessments.
Energy Price Protection
Care home operators have been significantly exposed to electricity price volatility since 2021. A solar system provides a hedge against future price rises: the electricity generated by the panels is effectively free throughout the system's 25-year life, insulating the care home from at least 40-70% of daytime electricity costs regardless of future grid prices. This price certainty has significant value for business planning and long-term financial modelling.
