8.6kWp Commercial Solar with 25kWh Battery Storage in Bromley

This 8.6kWp solar PV system with 25kWh of FoxESS battery storage at a doctors surgery in Bromley shows how commercial healthcare premises can cut running costs substantially without any disruption to day-to-day operations.

Medical practices run hardest during peak daytime hours, which makes them close to an ideal candidate for solar. The surgery's electricity demand lines up with the hours of maximum generation, so a high proportion of what the system produces is consumed on site rather than exported at low rates. Adding 25kWh of storage pushes those savings further, covering the early morning and evening either side of the practice day.

Installed around a working surgery

The array went onto a pitched roof using a Fastensol mounting system, a secure low-profile rail solution chosen for longevity and minimal maintenance. That matters more in a commercial setting than almost anywhere else, because nobody wants contractors back on the roof of a working medical facility. The installation was sequenced so the practice kept running throughout.

FoxESS storage was specified for its proven performance in commercial applications, high round-trip efficiency and real-time monitoring through the FoxESS cloud platform, which gives the practice manager full visibility of system performance and savings at any time.

At 8.6kWp the array generates roughly 7,310 kWh of clean electricity a year. Combined with 25kWh of storage, it delivers a measurable reduction in the surgery's annual electricity costs from the first month of operation.
