Solar panels for UK care homes — savings, resilience and CQC credentials
Care homes run 24 hours a day, seven days a week — which makes them one of the most predictable and profitable commercial solar hosts in the UK. Here's what to expect on cost, payback and back-up resilience.
Typical system sizes by care home
20-bed residential home
15–25 kWp. £14k–£23k. £2.8k–£5k/yr savings. Payback 5–7 years.
40-bed nursing home
40–70 kWp. £36k–£65k. £7k–£13k/yr savings. Very high self-consumption thanks to 24/7 heating, laundry and kitchen loads.
80-bed dementia care
80–150 kWp with battery back-up. £75k–£145k. £14k–£27k/yr savings — plus resilience during power cuts.
Multi-site care group
Portfolio rollout — typically PPA-funded to avoid capex across 5–30 sites. Reporting handled centrally.
Back-up power for vulnerable residents
Storm-related outages have doubled in the last decade. A solar + battery system with islanding keeps nurse calls, lifts, medical fridges and warmth running through a power cut — often the difference between staying open and evacuating.

FAQ
Are solar panels worth it for a UK care home?
Yes — care homes have some of the flattest, most predictable electricity demand of any sector. Self-consumption above 85% is typical, giving 5–7 year payback and a hedge against volatile winter bills that hurt care fees.
How much do solar panels cost for a care home?
£900–£1,150 per kWp installed at 20–150 kWp. A typical 40-bed nursing home needs 40–70 kWp and pays around £36k–£65k, saving £7k–£13k a year.
Does solar help with CQC sustainability requirements?
Yes. The CQC's new sustainability strand and the NHS Net Zero Supplier Roadmap both reward measurable on-site generation. Homes contracting with ICBs or local authorities increasingly need to demonstrate carbon reduction — solar is the fastest single lever.
Can solar keep the home running during a power cut?
Only with battery back-up and an islanding-capable inverter. A properly sized 30–50 kWh battery can keep essential circuits (nurse calls, lifts, refrigeration, medical devices) running for 4–8 hours.
What funding options are there for care home solar?
Charitable trusts and CIC operators access Salix and community energy grants; private groups typically use asset finance or PPAs (zero capex, day-one savings share).
