How do photovoltaic module manufacturers products adapt to roof installation?

For photovoltaic module manufacturers to make their products suitable for roof installation, they need to consider aspects such as product design, performance optimization, and installation methods, as follows:

Product design

Size and shape: Based on common roof sizes and shapes, design appropriate component sizes and shapes, such as rectangles or squares, to enhance the utilization rate of roof space. Meanwhile, lightweight components can be developed to reduce the load-bearing pressure on the roof and facilitate installation. For example, by adopting a thin design, the thickness of the components is reduced to less than 30 millimeters, and the weight is controlled at about 20 kilograms per square meter.

Appearance design: Considering the aesthetic appeal of roof installation, a variety of color and appearance style components can be launched, such as black, gray and other simple tones, to coordinate with different architectural styles. It can also be designed as semi-transparent or transparent components for special application scenarios such as skylights.

Performance optimization

High-efficiency power generation: Enhance the photoelectric conversion efficiency of photovoltaic modules to achieve greater power generation on a limited roof area. For instance, advanced battery technologies such as PERC and HJT are adopted to increase the conversion efficiency to over 22%. Meanwhile, optimize the optical design of the components, increase the absorption of light of different wavelengths, improve the weak light performance, and ensure stable power generation under different lighting conditions.

Wind resistance: Roofs are usually in exposed environments and are vulnerable to strong winds. Therefore, the components need to have good wind resistance performance. By optimizing the structural design of the components, increasing the strength of the frame and the stability of the connection, the components can withstand wind speeds of more than 50 meters per second. In addition, special installation brackets and fixation methods can be adopted to enhance the connection between the components and the roof and prevent them from being lifted by the wind.

Waterproof performance: To prevent rainwater leakage from damaging the roof, photovoltaic modules must have reliable waterproof performance. In addition to the sealing design of the components themselves, waterproof treatment should also be done well during the installation process, such as using waterproof glue, sealing gaskets, etc. Meanwhile, a reasonable drainage system should be designed to ensure that rainwater can be smoothly drained away and to prevent the erosion of components and the roof by accumulated water.

Installation method

Flexible installation brackets: Develop a variety of installation brackets to adapt to different types of roofs, such as flat roofs, pitched roofs, etc. The support should be adjustable, capable of adjusting the installation Angle of the components according to the slope and orientation of the roof to obtain the lighting conditions. For instance, by using an aluminum alloy bracket with adjustable angles, the components can be flexibly adjusted within the range of 0° to 45°.

Simple installation: Simplify the installation process of components, reduce installation time and cost. For example, design quick-connection interfaces and installation fixtures to make the connection between components more convenient, and the installation can be completed without complex tools and professional skills. Meanwhile, detailed installation guides and training materials are provided to help installers quickly master installation skills.

Safety and Maintenance

Electrical safety: Ensure that photovoltaic modules have good electrical insulation performance and are equipped with safety measures such as grounding protection to prevent leakage accidents. Set obvious safety signs on the surface of the components to remind personnel to pay attention to safety.

Easy to maintain: Photovoltaic module manufacturers design structures that are easy to maintain, facilitating inspection, cleaning and replacement of the modules. For example, sufficient spacing should be maintained between components to facilitate maintenance operations by personnel; It adopts a modular design. When a certain component malfunctions, it can be quickly disassembled and replaced without affecting the normal operation of other components.
