As the UK care sector faces rising energy costs and increasing environmental responsibility, many care homes are turning to solar energy as a sustainable solution. During the 2026 Care Show London, Rahi from Solar4Good shared powerful insights into why solar is becoming an essential upgrade for care homes across the country.
Summary (TL;DR)
Key facts about this topic:
- Care homes typically need 30-50 kW solar systems for 30-40 bed facilities
- Annual electricity savings range from 40-60% with 80-90% summer self-sufficiency
- Solar installations often pay for themselves in 3-4 years, sometimes as quickly as 2 years
- Battery storage is optional, depends on facility’s energy usage patterns and smart tariff availability
01The Care Sector’s Growing Interest in Solar Energy
Care homes are increasingly under pressure to manage tight operating budgets while maintaining compliance with environmental goals. As Rahi shared, solar energy provides a dual benefit:
- Lower energy bills
- Reduced carbon footprint
“Two main reasons why care homes are going solar: environmental responsibility and saving money.”
As of 2026, care homes are some of the most promising candidates for solar adoption, thanks to their large roof spaces and consistent energy usage throughout the day.
02Typical Solar System Size for Care Homes
During the interview, Rahi explained that while every care home has unique energy needs, a 30 to 40-bedded facility typically requires a solar system between 30 kW to 50 kW.
“Every care home is bespoke… but generally for a 30 to 40-bed care home, you’re looking at a 30-50 kW system.”
Such systems can power:
- Air conditioning
- Lighting and fans
- Kitchen equipment
- Laundry machines
This means that on sunny days, care homes can run a majority of their operations directly from solar energy.
03Seasonal Performance and Annual Savings
One common concern is whether solar panels are effective year-round in the UK. Rahi clarified this:
- Monocrystalline panels work on daylight, not heat, so generation continues even in winter.
- During summer months, care homes can be 80-90% self-sufficient.
- Over a yearly cycle, most clients see 40-60% savings on electricity bills.
These savings accumulate significantly, especially for care homes operating 24/7 with high energy demand.

The conversation touched on one of the most debated questions in solar today: is battery storage necessary for care homes?
Rahi’s answer: It depends.
Pros of Battery Storage:
- Stores excess solar energy for evening use.
- Can be filled using off-peak electricity and used during expensive hours.
- Useful for care homes with higher night-time energy needs.
Cons:
- Adds to upfront cost.
- Not always needed if most energy is used during the day.
“It’s 50/50. Some care homes don’t produce enough excess energy to justify a battery. Others benefit by charging it during off-peak hours.”
05Smart Tariffs: A Hidden Opportunity
The conversation also explored the value of smart electricity tariffs. The host shared their personal experience saving 23% on energy bills by using a smart tariff that charged less during non-business hours.
Care homes can apply similar logic:
- Use solar during the day
- Charge batteries at night using low-rate electricity
- Reduce reliance on peak-time energy
Combining solar + battery + smart tariff can create a powerful, cost-efficient solution.
06Surge in Demand Across the Healthcare Sector
Solar4Good isn’t just seeing interest from care homes. According to Rahi:
“We’re seeing inquiries from medical centres, pharmacies, and other healthcare facilities. They’re fed up with rising electricity bills.”
This shift is part of a broader trend where healthcare providers are actively seeking ways to become more energy-independent and future-ready.
The consistent rise in utility prices has turned solar from a “green” luxury into a financial necessity.
07Funding and Grants: What’s Available?
While government support is more limited than in the past, some local councils and associations still offer funding for green upgrades.
“There is funding about, it depends on the area and local authorities.”
Care home owners should:
- Check with local councils
- Explore Low Carbon Skills Fund (LCSF) or Salix Finance
- Investigate green commercial loans
Even partial grants can significantly reduce the payback period.
08Energy Audits: A Smart First Step
Rahi offered a practical piece of advice for all care home owners:
“Look into your energy bills. Get an energy audit. You’ll be surprised how much you can save.”
An energy audit can:
- Highlight inefficiencies
- Determine optimal solar system size
- Uncover quick wins before investing in panels
Companies like Solar4Good often provide this as part of the consultation process.
09Return on Investment: How Fast Can You Break Even?
One of the most compelling points was the ROI figures mentioned. In many cases, solar installations in care homes pay for themselves in 3 to 4 years.
In some cases?
“I heard of a care home that broke even in just 2 years.”
This kind of payback period makes solar one of the most strategic investments for care homes in 2026.
Final Thoughts: Why 2026 Is the Time to Act
If you’re a care home owner or operator, 2026 is a critical window of opportunity to explore solar.
Why now?
- Energy costs are surging
- Sustainability is no longer optional
- Technology has matured and offers higher efficiency
- Public funding, while limited, is still available
- Patients and families are increasingly aware of green practices
“Your age goes up. Your electricity bills go up. That’s guaranteed. Solar is one of the few tools to push back.”
The discussion at the Care Show London was more than a technical conversation, it was a rallying call to the care sector to step into a cleaner, smarter future.
Manan co-founded Solar4Good to do solar differently, as a partner, not a salesperson. After 15 years in London finance, he treats a solar system as the financial decision it is: every customer gets an honest, numbers-first projection of cost, savings and payback, not a sales promise.
