Description

Photovoltaic module device

Technical Field

The utility model relates to the technical field of solar power generation, in particular to a photovoltaic module device.

Background

Traditional roof photovoltaic power generation (system) belongs to distributed photovoltaic power generation system. Roof photovoltaic power generation systems generally utilize factory building roofs, idle lands and licensed public places as construction sites, and the systems mainly comprise solar photovoltaic panel assemblies, inverters, junction boxes, power distribution cabinets and the like, and electric energy is transmitted to a public power grid through accessing the public power grid to acquire electric charges and special subsidy so as to achieve economic benefits. The power station can adopt two operation modes of 'self-use, balance surfing' and 'full surfing' according to the wish of an owner. The roof photovoltaic power generation has important significance for optimizing the energy structure, promoting energy conservation and emission reduction and realizing economic sustainable development.

When the cement roof photovoltaic module is installed, the module is installed and the roof can form an angle due to the fact that the cement roof photovoltaic module is suitable for sunlight. The higher the installation dimension, the greater the component installation angle. When wind blows from the high end of the assembly to the low end, a certain wind pressure is formed on the back of the assembly. Roof photovoltaics typically counteract the effects of wind pressure by adding a counterweight below the assembly. However, when typhoons or stronger wind blow, the wind pressure is too large, and the photovoltaic module is extremely easy to damage and even has the risk of toppling over.
