royal united hospitals (ruh) therapies centre, bath

photon energy has installed 75kwp of solar pv at the royal united hospitals therapies centre in bath.

Photon Energy have been tasked with providing 75kWp of Solar PV panels to the Royal United Hospitals (RUH) new therapies centre located in Bath.

The PV modules used were Bisol BMO-300 and were installed in two roof areas. Eighty-eight PV modules on the new roof and the remainder on the existing roof.

In order to maximise output from the solar PV and provide an enhanced level of safety, SolarEdge inverters were installed with a SolarEdge Firefighter Gateway linking the PV array to the fire alarm system. This additional security enables shut down at module level in the event of a fire.

The solar modules were fixed to a 10˚ pitch mounting system.

The new therapies centre is being built close to the main entrance of the Royal United Hospitals. It will be an outpatient centre providing treatment, care and education for patients to recover from illness, injury or to manage a long term condition.

Photon Energy has been working on both the existing RUH building and the new development to reduce the carbon emissions. The annual energy generated by solar PV will provide a combination of 71,078 kWh/year.
