This causes a behaviour opposite to the trend observed for PV panels installed at 50–100 cm on both roofs. However, such situation did not reduce the FWG value of PV panels installed on the concrete roof; in fact, Fig. 10 shows that the FWG value increased. This increase was because the reflective coating of the terrace slightly augmented the
