Introduction

The efficiency of solar panels installed on flat roofs has been a topic of interest for building owners seeking sustainable energy solutions. Flat roofs offer unique installation advantages but also present challenges related to optimal solar panel performance.

Factors Affecting Solar Panel Efficiency on Flat Roofs

1. Tilt Angle

Solar panel efficiency is highly dependent on the angle at which they are tilted. Ideally, panels should be angled equal to the latitude of the installation location to maximize sun exposure. However, flat roofs often necessitate mounting systems to achieve optimal tilt.

2. Shading

Flat roofs may be subject to shading from nearby objects or buildings, affecting output. It is crucial to conduct a shading analysis to mitigate energy loss and maximize efficiency.

3. Orientation

South-facing panels in the northern hemisphere receive the most sunlight, enhancing efficiency. Flat roofs require careful design to ensure an optimal southward orientation.

Numerical Analysis of Solar Panel Efficiency

Numerical simulations and real-world testing suggest that solar panels on flat roofs can achieve efficiencies of 15-20% under optimal conditions. Adjusting the tilt angle by 10-15 degrees increases energy yield by approximately 10-12%, mitigating potential efficiency losses.
