Hi,
After a ground survey, the NaREC site map confirms this is still the Brunel Building, and a big wall sign says 'PV Technology Centre'. https://www.solarcapturetechnologies.com/ is mentioned on window graphics, so confirmed.
I've also added the PV + thermal panels, although wall vertical mounting next to shading trees seems an odd choice!

Happy Mapping,
