(a, b) Energy harvesting testing arrangement enabling daily comparisons of energy produced by the test window and wall-mounted solar windows of other design types. The Test Window was connected to Victron 75/10 charging regulator using a 12 V battery in bulk charging mode as energy sink. (c) Wall-based PV arrays closest to the test window (12-window arrays J and F, and 6 of the wall-mounted Array C windows out of total 12). Empty white rectangles on diagram indicate non-solar windows used for room ventilation. The lifetime array generation data are shown for the period between 15 April 2021 and 18 January 2023; 720 kWh/Array C and 492 kWh/Array B, due to a known diagram data outputs error swapping the data indicators of arrays B and C.
