A healthcare site that runs on daytime power
Fairview Health is a specialty pharmacy in Park Royal, north-west London, supplying medicines to hospitals and community health trust clinics. It is an energy-hungry building. Cold storage for medicines, lighting and equipment run through the working day, and nearly all of that demand lands in daylight hours. On paper that makes Fairview an ideal solar customer, using the power at the exact moment the panels make it. As bills kept climbing, Fairview wanted more than a smaller invoice. They wanted predictable costs, and to show staff and clients they were serious about cleaner energy.
A power bill that only climbed
Electricity had become one of the pharmacy’s biggest running costs, and it was only heading one way. With cold storage and equipment drawing power all day, the pharmacy was buying nearly all of it from the grid at daytime rates. They wanted a way to cap those costs for the long term, cut their carbon, and do it without shutting down a working pharmacy to fit the system.
A 21.2 kWp system, sized to the daytime load
We didn't discount the roof. We designed around it. We ran the whole job end to end, from site visit and design through to install and commissioning, and we scheduled it so not one appointment or shift was disrupted. The total came to £17,500, with headroom left to add battery storage down the line.
- 50 × Jinko 425W panels (21.2 kWp total), picked for efficiency and reliability
- 1 × Growatt MID 20 KTL3-X (20 kW) inverter
- Sized around the pharmacy’s heavy daytime electricity load
- Installed around a working pharmacy with zero disruption, and future-proofed for battery
Two-thirds off the electricity bill, from day one
The system now cuts Fairview’s electricity bill by 67%. With the install costing £17,500, a system like it typically pays for itself in five to six years. After that, it is clean power the pharmacy runs on for free. Over the system’s 25-year life that is roughly £80,000 to £106,000, on an install that typically pays for itself in five to six years.
