As the first type of the studies mentioned above, the shading effect of rooftop PV panels on energy consumption and thermal performance of buildings have been investigated in several studies. For instance, the effect of four different roofs was assessed on the building's thermal loads.
Using PV panels are considered one of the main strategies to generate electricity from sun exposure. Besides energy generation, a roof-added PV system affects the building's energy consumption due to its shading effect. Shading effects would differ depending on the roof's thermal properties, climate, and PV system design.
As reducing the building energy load is one of the most important issues in architecture, the shading effect of PV panels is noteworthy. According to the results, adding PV panels have a noticeable effect on a building's roof thermal performance. The main findings of the study are as follow:
China's pursuit of photovoltaic (PV) power, particularly rooftop installations, addresses energy and ecological challenges, aiming to reduce basic energy consumption by 50% by 2030. The northwest region, with its solar potential, is a focal point for distributed PV growth, which has already exceeded 50% of the energy mix by 2021.
