Solar battery module

Abstract

A solar battery cell having a hexagonal shape is divided into four at a straight line connecting between opposed apexes and a straight line connecting between middle points of opposed sides. Two of the divided cells are arranged; thus, a substantially rectangular-shaped unit is configured. In adjoining two units, an interconnector is routed from a front surface of one of the units to a back surface of the other unit. Thus, the two units are electrically connected to each other through the interconnector. Hence, it is unnecessary to route an interconnector from a front surface of one divided cell to a back surface of another divided cell at a portion where oblique sides of the divided cells oppose each other; therefore, it is unnecessary to secure a large clearance at the portion.

Description

technical field [0001] The present invention relates to a solar cell module, particularly a solar cell module suitable for use when improving the filling efficiency of solar cell cells. Background technique [0002] Against the backdrop of the depletion of petroleum resources and global warming, the development and spread of clean energy without using petroleum resources has been proposed as a global issue. Solar power generation system has no CO due to the use of inexhaustible solar energy 2 and other emissions, so it has attracted attention as a technology that plays an important role in solving such problems. [0003] In such a photovoltaic power generation system, in order to protect the solar cell elements as a power generation source from damage and to facilitate handling, a solar cell module in which several tens of solar cell elements are arranged in a planar shape is generally used. Among them, since it is necessary to effectively cover the solar cell elements in ...

AI Technical Summary

Problems solved by technology

[0011] However, according to the structure described in the above-mentioned patent document 2, the hypotenuses of the components divided into two parts are opposed to each other. Part of the gap is relatively large, this part will reduce the component filling rate

In addition, once the connecting member is introduced from above to below through the beveled portion in this way, chips or cracks are likely to be generated on the element at the beveled portion, which is likely to cause a problem of breakage on the element.

In addition, in the case of connecting elements with a plurality of connectors, since the oblique sides of the elements are bent, the bending position of each connector is different, and there is a problem that the connecting work of the connectors becomes complicated.

[0012] In addition, in the above-mentioned Patent Document 1, there is no description about the wiring of elements using connectors.
