Optimizing Solar Performance: The Role of Optimal Tilt Angle and Mounting Height in Rooftop PV Systems

As the solar energy industry continues to grow, researchers are constantly exploring ways to optimize PV systems for maximum performance, especially in real-world conditions. A new study from Guilin University of Electronic Technology has shed light on an essential factor: the impact of the optimal tilt angle and mounting height of rooftop solar panels on energy efficiency and overall system performance.

The Critical Role of Optimal Tilt Angle

The tilt angle of solar panels directly influences their energy efficiency. Proper installation ensures maximum solar radiation absorption, improving energy output and return on investment (ROI). Research shows that The optimal power supply gain and comprehensive energy-saving efficiency are achieved with a 20◦ tilt angle, with Epvr value of 79.4 kW⋅h/m2 and efficiency of 25.5%. However, adjusting the overhead height slightly affects the cooling load difference between conventional and photovoltaic roofs, but has negligible impact on overall energy savings.

At Qn-SOLAR, we recognize the importance of achieving the correct tilt angle. By ensuring proper installation practices, we help customers unlock the full potential of our solar modules for maximum efficiency and performance.
