The application field of flat roof photovoltaic support system is wide, covering multiple fields such as residential buildings, commercial buildings, industrial plants, etc. Among them, residential buildings have become the main source of demand for flat roof photovoltaic support systems due to their huge market demand and vast market space, accounting for about 40% of the market share.

Faced with numerous photovoltaic bracket solutions, the following are three aspects that need to be paid attention:

1. Avoid flat placement of solar panels: Installing modules in a flat manner can easily accumulate dust, resulting in loss of power generation, inconvenient cleaning, and difficulty in removing accumulated water. It is also difficult to remove dust through natural rainfall. It is recommended to make a certain inclination angle when laying flat, usually 5-10 degrees, while facing towards the optimal orientation.

2. Consider the issue of obstruction: The power generation efficiency of solar panels is highly dependent on direct sunlight, and if they are obstructed by trees, buildings, etc., it will seriously affect the power generation efficiency. Before installation, shadow obstructions should be eliminated. If the obstruction source cannot be removed, consideration should be given to changing the installation site.

3. Pay attention to roof structure and waterproofing issues: The weight of photovoltaic panels and solar mounting structures may put pressure on old or structurally weak roofs. The long-term load caused by installing PV brackets may lead to fatigue and potential damage to the roof structure. Some solar roof brackets require drilling holes on the roof during installation, which can damage the original waterproof layer and increase the possibility of water leakage. So before installation, it is necessary to evaluate and repair the roof structure and waterproof layer.

For the installation of flat roof solar brackets, commonly used are ballast type and concrete foundation mounting brackets type. CORIGY has more than 15 years of experience in photovoltaic bracket design and production, and can provide various professional design solutions based on the load-bearing capacity of the roof to ensure that the bracket installation is simple, firm, and efficient in generating electricity within safe wind speeds.
