Research on synergistic effect and bearing capacity of solar composite roof panel

Taking the two new connection forms of PV (photovoltaic) panels and sloping roof — "external form" and "embedded form" designed in this paper as the research objects, the bearing performance of PV panels have been studied by static loading test. The deflection and strain characteristics of PV panels under two kinds of connection forms are compared and analyzed. The results show that when the load is added to 1.0kN, the deflections of the PV panels under two connections forms are less than the theoretical value of 16.82mm, meeting the normal use requirements; when the load is added to 2.1kN, the maximum strains of the PV panels are less than the limit strain 1712µe, the PV panels are not failure. The PV plate has better bearing performance under the new "external form" connection form with smaller deflection and strain, which can be used as a new solution for the integration of PV construction.
