Initial validation of the one-diode photovoltaic model for the flexible panels

The PV panels integrated on the wall are mainly heavy cladding systems, disabled to apply in certain buildings because of the limitations of construction strength. The authors proposed a new solution with flexible PV panels mounted without additional sub-construction. In the presented paper, two aims were formulated: to compare the performance of the free-standing (FSPV) and integrated insulation wall system PV (WIPV) panels experimentally as well as verify the existing one-diode equivalent models implemented in ESP-r: Kelly’s and WATSUN-PV model. The experimental results show that the (WIPV) system can influence significantly on the temperature and slightly on the power of PV panels.
