Comparative Performance of BAPV Systems in Scotland: 4 Case Studies with Differing Energy Contexts
Abstract
The paper compares the performances of four building-added photovoltaic (BAPV) systems, one located in a North-East maritime location, one in a North-West maritime location and two in East Central Scotland. Each BAPV system will be described within the overall energy context of its host building, all with varying functions – a refurbished further education campus, a new-build community centre, bespoke new offices and an existing factory and company headquarters. The last two are concerned with solar branding, while the first two place BAPV discreetly within a wider energy strategy that exploits solar energy thermally by various means, some less directly than others. The paper confirms respectable outputs from each of the PV arrays, ranging from 705 to almost 900 kWh/kWp, but with varying output significance, partly due to PV array area and configuration range from 72 to 647 m2, relative to the overall energy demand.
