ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to a terminal lead-out structure and a solar-cell apparatus provided with such structure. More particularly, the invention relates to a highly reliable terminal lead-out structure having a good operativity in leading out a terminal, and relates to a solar-cell apparatus provided with such structure.
2. Related Background Art
In recent years, the consciousness of environmental problems has increasingly intensified and widely spread all over the world. Particularly, apprehensions are sensed more seriously with respect to the warming phenomena of the earth brought about by the CO

emission. The provision of clean energy is more in demand increasingly. At present, a solar cell is regarded as a source of clean energy because it is safe and easy to handle.
There are various modes of solar cells. As typical ones, the following can be named: (1) a crystal silicon solar cell, (2) a polycrystalline silicon solar cell, and other crystalline silicon solar cells, (3) an amorphous silicon solar cell, (4) a copper indium selenide solar cell, and (5) a compound semiconductor solar cell, among others. Conceivably, it is possible to produce, among those solar cells, thin filmed crystalline solar cells, compound semiconductor solar cells, and amorphous silicon solar cells on a large scale at comparatively low costs. Therefore, research and development on them have been in progress in many fields in recent years.
Usually, the solar cell elements, which generate solar power and constitute solar cells, are buried in a filling agent, such as EVA (ethylene-butyl vinyl copolymer) or the like. Also, each of the solar cell elements buried in such filling agent is sandwiched between a surface coating material and a rear side reinforcement material. Each of them is used as a module (a solar cell module). In this case, glass or weatherability film, such as fluororesin film, is adopted as the surface coating material. Also, as the rear side reinforcement material, the following is used, among others: a weatherability and damp-proof film structured by sandwiching aluminum foil with weatherability films; a thin steel plate such as uncoated galvanized steel plate; a steel plate coated by polyester resin or acrylic resin in consideration of its bending capability, hardness, and others; or a plastic plate.
As an output terminal of such solar cell module, there has been conventionally used, among others, a screw fixation type, a lead line type, or a socket type. For any one of them, there is often produced a terminal lead-out structure, such as a terminal box having a water-proof structure for insulation.
Also, for the structure of the terminal lead-out unit of a portable solar cell module, there is, among others, just a simple structure wherein soldered terminals are buried in a filling agent or wherein such terminal unit is covered by a thermal contraction tube or a rubber cover, which dually serves as an edge cover of the module.
Now, as described above, a solar cell is generally used as a clean and non-exhaustive source of energy supply. Also, research and development is carried on in various ways, including an active development of solar cell module well suited for the installation on the ground as well as on the roof.
Particularly, with respect to the installation on the roof, it is useful to develop a solar cell module that functions dually as a roofing material, such as the one being formed integrally with a roofing material, so as to lower the costs for promoting use of solar cells more in the future.
However, if the terminal lead-out structure of a solar cell module is such that the soldered portions are simply covered by insulators, there is a problem that the tension exerted on the terminal lead line is directly carried over to the electrode lead-out unit of the solar cell module.
The other problems encountered in this respect are that the fluororesin film used as the surface coating material for a solar cell module and the filling agent are not adhesively bonded well so that rainwater permeates through the interface between them, the terminal box cannot be fixed on the light receiving surface side of a solar cell module, or some others.
