AI Technical Summary
When photovoltaic modules are fixedly installed on concrete roofs, there are problems such as cracking of the concrete substrate and loosening of bolts due to pre-embedding work, which affect the structural stability and power generation efficiency of the support system. In addition, the fixed tilt angle design cannot adapt to seasonal changes in solar radiation, resulting in unstable power generation efficiency.
The rooftop photovoltaic support system, which features adjustable installation tilt angle, includes a concrete base, lifting supports, support fixing structure, and inclined beams. Adjustable fastening devices and bolt connections enable flexible installation and tilt angle adjustment of photovoltaic modules, thereby improving power generation efficiency.
Stable installation of photovoltaic modules was achieved, reducing installation steps and improving power generation efficiency. Furthermore, the power generation performance of the modules was enhanced by adjusting the height of the lifting support to change the angle of sunlight.
