Solar Cell Module and Solar Cell Array

Abstract

It is an object to provide a solar cell module having a uniform configuration, presenting stable output characteristics, and having a size enabling easy wiring in arrangement and a solar cell array presenting stable output characteristics by employment of said solar cell modules.

A solar cell module 10 has a solar cell panel 12 having a length of its longer edges of 900 to 1100 mm. The solar cell panel 12 is constituted by a number of unit solar cells 100 connected in series and has an open-circuit voltage of 100 to 180 volts. The unit solar cell 100 is of a strip-like shape with a length of its shorter edges of 7 to 12 mm and arranged in a longer-edge direction of the panel 12 so that its longer edges extend in a shorter-edge direction of the panel 12 and its shorter edges extend in the longer-edge direction of the panel 12.

Description

TECHNICAL FIELD[0001]The present invention relates to a solar cell module for constituting a solar cell array arranged on a house and to a solar cell array constituted by the solar cell modules.BACKGROUND ART[0002]Recently, a photovoltaic system with solar cell modules having solar cell panels arranged on a place such as a roof of a house has increased for covering electricity consumed at the house and simultaneously selling surplus electricity to an electric power company. A solar cell panel is an integrated solar cell, which is formed by laminating a film such as a conducting film and a semiconductor film on a glass substrate, cutting a plurality of grooves on the laminated layer so as to form a predetermined number of one-cell batteries (unit solar cells), and electrically connecting the unit solar cells in series. It is known that some panels generate a voltage of 100 volts or more. The Patent Document 1 specified below discloses a method for manufacturing such a solar cell pane...

Benefits of technology

[0066]The present invention provides a solar cell module having a uniform configuration, presenting stable output performances, and having a size enabling easy wiring in arrangement and a solar cell array presenting stable output performances by employment of said solar cell modules.

Problems solved by technology

However, in view of convenience of arrangement or manufacture, there is a limit to a size of the module and also some limits to the number of and an output voltage of the unit solar cells being connectable in series in the sole module.
