What should be considered when installing photovoltaic systems on color steel roofs?
When installing photovoltaic (PV) systems on color steel roofs, several key considerations must be taken into account. Color steel plates are typically used in lightweight steel structures, such as standardized factories and warehouses, and their lightweight nature allows for extensive PV module installation. However, traditional mounting methods cannot be used because color steel panels are made of thin metal coated foam, necessitating the use of specialized clamps that do not compromise the existing structure or cause leaks.
For angular and direct-lock color steel panels, clamps can be directly used as the support base for solar panels without affecting their integrity, making these two types of roofs ideal for distributed rooftop PV systems. Conversely, trapezoidal color steel roofs may face integrity issues when installing solar panel supports, leading to potential leakage risks, so adequate waterproofing measures are essential after installation.
The installation of PV modules on color steel roofs relies on clamps, which are lightweight and do not impose high load requirements on the roof. To ensure safety, multiple supports may be needed to maintain the optimal angle for the PV modules while considering the roof's load capacity.
