Description

Solar cell module {SOLAR CELL MODULE}

An embodiment relates to a solar cell module.

Photovoltaic modules that convert light energy into electrical energy using photovoltaic conversion effects are widely used as means for obtaining pollution-free energy contributing to conservation of the global environment.

As the photovoltaic conversion efficiency of solar cells is improved, many photovoltaic power generation systems equipped with photovoltaic power generation modules have been installed for residential use.

In order to output electric power generated from a solar power generation module having a solar cell that generates power from daylight to the outside, conductors serving as both electrodes and negative electrodes are disposed in the solar power generation module, And the ends of the conductors are taken out of the photovoltaic module.

In the case of BIPV (Building Integrated Photovoltaic System) module, which is used to replace the transparent glass of the building, a frame is installed to accommodate the solar cell module. In order to fasten the frame, a corner key is positioned between the frame and the frame. This corner key has the advantage that the frame can be lighter than the bolt fastening method, but there is a problem that additional weight is difficult due to the structure of the corner key itself.

Embodiments provide a solar cell module with improved reliability.

Solar cell module according to an embodiment, the solar cell panel; A first frame and a second frame accommodating the solar cell panel and neighboring each other; And a connecting member inserted between the first frame and the second frame, wherein the connecting member includes an open area exposing the inside of the connecting member.

The solar cell module according to the embodiment includes a connection member, and the connection member includes an open area exposing the inside of the connection member. Since the connection member is provided to include an open area so that the inside thereof is empty, the weight of the solar cell module can be reduced. That is, it is possible to improve the reliability by reducing the solar cell module. In particular, the smaller the area of the solar cell module, the higher the proportion of the connection member occupies. In the solar cell module according to the embodiment, the structure can be improved by reducing the weight of the connection member.
