Problems solved by technology

The instantaneous voltage of a lightning strike is as high as tens of thousands to millions of volts. The current production module test is only 6,000 volts. Therefore, if the solar cell module is struck by lightning outdoors, its function will inevitably be damaged.

Embodiment Construction

[0016] The embodiments of the present invention will be clearly explained below with the accompanying drawings and detailed description. For the sake of simplifying the accompanying drawings, some known and commonly used structures and components will be shown in a simple and schematic manner in the accompanying drawings.

[0017] see figure 1 , which shows a side view of a conventional solar cell module structure. Such as figure 1 As shown, the frame 100 is an aluminum frame, which is set on the ground to carry the solar battery module. The solar cell module is in the form of a plate as a whole, which includes a base plate 102 and an upper plate body 104 filled with an encapsulant 106 and has a plurality of solar cells 108 . Wherein, the upper plate body 104 is a glass plate, and the light is directly irradiated on the upper plate body 104 . In this embodiment, the encapsulant 106 is low-foaming polyethylene foam (EVA), but it is not limited thereto. The encapsulant 106 i...

Abstract

The invention provides a solar battery module structure. The solar battery module structure comprises a framework, a solar battery module arranged on the framework, and a metal grid; the solar battery module comprises a base plate and an upper plate body; an encapsulant is filled between the base plate and the upper plate body; the solar battery module is provided with a plurality of solar batteries; the metal grid is arranged on the framework, positioned above the solar battery module and not contacted with the solar battery module; and the metal grid is grounded electrically. By the solar battery module structure provided by the invention, when lightning stroke is generated, current is leaded into the ground so as to prevent instant huge current from flowing through the solar battery module and further breaking the solar battery module.

Description

technical field [0001] The invention relates to a solar cell module structure, in particular to a solar cell module structure capable of preventing lightning damage. Background technique [0002] At present, non-renewable energy sources such as electricity, coal, and oil are frequently running out, and energy issues have increasingly become a bottleneck restricting the development of the international society and economy. More and more countries have begun to implement the "Sunshine Plan" to develop solar energy resources and seek new impetus for economic development. Driven by the huge potential of the international photovoltaic market, solar cell manufacturing has become an emerging industry. [0003] The global solar cell industry increased by 17 times in 10 years from 1994 to 2004, and the production of solar cells is mainly distributed in Japan, Europe and the United States. In 2006, the installed scale of solar cells in the world reached 1744MW, an increase of 19% co...
