Nowadays, due to the increase in greenhouse gas concentrations and environmental pollution caused by fossil fuels, there is a great emphasis on using solar energy as a clean source of electricity generation. Most solar systems used in the world are of two types: BAPV (Building Applied Photovoltaic) and BIPV (Building Integrated Photovoltaic). In this study, the BAPV and BIPV solar systems and their performance on horizontal and sloping roofs in Urmia city are investigated. For this purpose, the effect of the slope angle on the panel efficiency and annual energy production is examined at different angles using the PVsyst 7.2 simulation software. The simulation results show that the proposed system for a sloping roof with a 35-degree angle has the highest solar energy absorption rate. Comparing the panel efficiency on a sloping roof with a 35-degree angle and a horizontal roof, it is found that with the same number of panels, the efficiency of panels on a sloping roof in the BAPV system is 16% higher and in the BIPV system is 14% higher than that of a horizontal roof. Moreover, the amount of unused solar energy on sloping roofs with a 35-degree angle is 3.5% lower than that of a horizontal roof, considering the consumption pattern in BAPV and BIPV systems. Additionally, by sloping the roof at a 35-degree angle, the accessible space in the examined sample increases by 20%, which can be used for installing more solar panels.
