JBM were contracted to deliver a 30kW PV system on the roof of The Sharnbrook Hotel. The system now generates enough power to make a significant contribution to the energy needs of the hotel. The building has a flat roof surrounded by parapets and therefore the preferred solution was a ballasted system. Due to the extra weight of such a system a structural survey was carried out on the building to understand its ability to support further loads. The result of the survey showed that it was necessary to reinforce the roof of the hotel with additional bracing to ensure the structural integrity of the building. This work was carried out by JBM in addition to the PV installation.
