A trigger for this report was a fire in a building under construction. The reporter was alarmed by the fact that building-integrated photovoltaic (BIPV) panels were present in the building rather than building-attached photovoltaics (BAPV). The main difference between them is that BAPVs are fitted on existing surfaces that comprise the structure (such as flat or tiled roofs), whereas BIPVs essentially replace structural elements and become part of the building (potentially a facade or roof element). It is still uncertain whether the PV panels caused the fire.
