The urgency of rooftop solar uptake has only been accelerated by the current energy crisis, but the spread of PV to historic and landmarked buildings remains limited. In Europe, historic buildings constructed before 1945 represent at least a quarter of total building stock. To boost uptake, some municipalities are considering a loosening of their protection policies, while researchers are finding interesting byways for installation. Furthermore, building integrated PV solutions are being touted as the ideal compromise between aesthetic continuity and new generation opportunities.
Gloucester Cathedral in England installed a 38 kW system atop its roof in 2016. The 150-panel system has reduced the cathedral’s energy costs by over 25%. Gloucester Cathedral also worked with installer Mypower to find the right balance of capital cost and electricity yield while ensuring the panel design closely complemented the aesthetics of the roof.
