Performance and Features of Fixed Photovoltaic Brackets
As an important component of photovoltaic power stations, the choice of photovoltaic brackets directly impacts the operational safety and breakage rate of photovoltaic modules. Choosing the right photovoltaic brackets not only reduces project costs but also minimizes maintenance expenses in the later stages.
Fixed photovoltaic brackets do not rotate with the changing angle of solar incidence but receive solar radiation in a fixed manner. They are categorized based on the set tilt angle into: optimal tilt fixed type, adjustable tilt fixed type, and sloped roof fixed type.
Optimal Tilt Fixed Type: The tilt angle is fixed at the angle that maximizes solar radiation, ensuring the highest cumulative radiation throughout the year. The optimal installation angle for the local area is first calculated, and all module arrays are installed at this fixed angle. This type is widely used in flat-roof and ground-mounted power stations.
Adjustable Tilt Fixed Type: The tilt angle is periodically adjusted based on changes in solar radiation angles to optimize radiation collection for different seasons. It is widely used in flat-roof and ground-mounted power stations.
Sloped Roof Fixed Type: The tilt angle is fixed according to the slope of the roof, with some loss in solar radiation. It is commonly used in tile roofs and color steel tile roof power stations.
