Why Hospitals Should Consider Solar Panels

Hospitals and healthcare sites face rising energy costs, sustainability regulations, and the need for reliable, low-carbon power. Solar panels provide a proven, cost-effective solution for cutting electricity bills and improving environmental performance.

By generating clean electricity on-site, hospitals, clinics, and hospices can reduce grid reliance, stabilise long-term budgets, raise their EPC ratings, and free up funds for essential services. Solar also strengthens resilience against price fluctuations and power interruptions, supporting uninterrupted care while helping healthcare organisations meet NHS Net Zero and Green Plan targets.

Spirit Energy helped many healthcare facilities in their solar journey:
St. Michael's Hospice and St. Peter's Hospice.

The Case for Solar in Healthcare: Reliable, Sustainable, and Cost-Effective

As healthcare providers face rising energy costs, tighter sustainability regulations, and increasing demands for energy security, solar power offers a resilient and future-proof solution. Hospitals, clinics, and hospices operate continuously, relying on stable, affordable electricity for patient care and critical equipment.

Beyond energy resilience, clean generation supports carbon reduction targets and strengthens public trust by showing a visible commitment to sustainability. For healthcare organisations adapting to new digital and environmental standards, solar energy isn’t just a cost-saving measure - it’s a strategic investment in long-term efficiency, resilience, and reputation.

What is the Payback Period for Hospitals Solar?

For most hospitals and healthcare sites, the payback period for a solar installation typically ranges from 6 to 10 years, depending on system size, energy usage, and available funding support. Because hospitals and hospices operate 24/7, their high electricity demand allows them to achieve faster returns through continuous on-site generation and reduced grid reliance.

When combined with battery storage, solar energy can further offset peak-time tariffs and improve long-term cost stability. Many healthcare organisations also access government grants, interest-free financing, or Power Purchase Agreements (PPAs) that shorten the payback window. 

How Hospitals' Solar Power Supports NHS Net-Zero Targets

Hospitals play a vital role not only in protecting public health but also in reducing environmental impact. With energy use among the highest in the public sector, many NHS Trusts and private hospitals are now prioritising sustainability and carbon reduction as part of their operational strategy. Solar energy supports these goals by lowering emissions, stabilising long-term energy costs, and reducing dependence on fossil fuels.

FAQ

Solar power offers hospitals and other healthcare facilities a powerful combination of cost savings, energy security, and sustainability. By generating clean electricity on-site, hospitals can reduce their dependence on grid power, lower operational costs, and stabilise budgets against rising energy prices. Environmentally, solar helps healthcare providers meet NHS Net Zero and ESG reporting targets by cutting carbon emissions. Beyond compliance, visible renewable energy systems also enhance a hospital’s public image, demonstrating leadership in sustainability and community care.

No. Installations are carefully planned to ensure no disruption to medical services. Panels are fitted on suitable roof areas, and Spirit Energy’s teams work with hospital and site managers to maintain access routes, emergency exits, and compliance with infection-control procedures throughout the project.

While a battery storage system can greatly enhance a hospital’s solar installation by storing excess energy and reducing grid reliance during peak hours, it is not designed to support critical life-safety systems. In most healthcare environments, those systems - such as emergency lighting, operating theatres, and intensive care equipment - must remain connected to dedicated backup generators that meet strict regulatory standards.

Yes. The NHS aims for Net Zero carbon emissions by 2040, and solar power is a proven way to reduce Scope 2 emissions from electricity use. Solar systems can be integrated with energy monitoring platforms to provide verified carbon data for Green Plan and ESG reporting.

Absolutely. Even small-scale systems can offset a significant portion of annual electricity use. Sites such as hospices, GP clinics, dental practices, and rehabilitation centres can achieve fast returns and visible sustainability gains through tailored solar installations.

Installing EV chargers at hospitals and healthcare facilities supports both staff and visitor sustainability goals. By integrating EV charging with on-site solar generation, hospitals can offer low-carbon vehicle charging powered by renewable energy, reducing overall emissions and operating costs.

University Hospital Case Study 

Spirit Energy installed an award winning 123kWp system on a new maternity wing of the North Middlesex University Hospital. Based on the high electricity demand of the hospital it is predicted that the hospital will use 100% of electricity generated by the Solar PV. 

The system is expected to pay for itself in 7 years, resulting in a total annual income and savings of approximately £19,000.  The site serves as an example of Spirit Solar’s innovation as a custom mounting solution was designed around the hospital’s unique roof covering.

St. Michael's Hospice installed by Spirit Energy, 2024

Expanding Solar Power Across Healthcare 

The installation at St Michael’s Hospice shows how solar energy is transforming not only hospitals but also a wider range of healthcare facilities seeking to reduce costs and carbon emissions. Working with Spirit Energy, the hospice installed a 60.2 kWp solar PV system using 140 Trina 440W panels and Solis inverters, designed to maximise roof space efficiency while maintaining safety and accessibility.

The system is expected to generate nearly 49,000 kWh of clean electricity each year, cutting energy bills by around £12,700 annually and reducing the hospice’s carbon footprint by over 12 tonnes of CO₂. With a five-year payback period, the project demonstrates how renewable energy can deliver rapid returns and long-term sustainability benefits, even for smaller healthcare providers.
