example 1

[0215] In this example a magnet is used as a non-volatile readable and writable storage medium.

[0216] Specifically, providing Figure 5 A solar module in the configuration shown. exist Figure 5 In, reference numeral 52 denotes a solar cell module, which includes a frame-shaped structure 55 having a light receiving surface provided with a power generation region 57 [including electrically connected to each other and covered by a surface side covering material (not shown) and a backside A plurality of solar cells sealed by a cover material (not shown)].

[0217] A magnetic tape 51 having a length of 50 mm and a width of 10 mm was fixed to a predetermined portion without solar cells outside the power generation region 57 on the light receiving face of the solar cell module 52 using an adhesive. The tape 51 here has the same dark gray exterior color as the frame of the solar cell module in order to make the tape unobtrusive.

[0218] As the read-write head, a modified vers...

example 2

[0233] The procedure of Example 1 is repeated except that a nonvolatile readable and writable storage medium is used instead of the magnetic tape to provide a semiconductor nonvolatile memory in the solar cell module, and since the semiconductor nonvolatile memory is used, it is also A control circuit for a semiconductor nonvolatile memory and an I / O connector as a data input-output device are provided in the solar cell module. In particular, a semiconductor nonvolatile memory and a control circuit may be provided on the rear side (non-light-receiving side) of the solar cell module in consideration of environmental resistance. And in consideration of wiring after installation of the solar cell module, the I / O connector may be bonded to a predetermined portion of the light receiving face of the solar cell module without solar cells outside the power generation area. The I / O connectors here have the same dark gray exterior color as the frame of the solar module in order to make ...

example 3

[0238] In this example, as in Example 2, a semiconductor nonvolatile memory and a control circuit for the semiconductor nonvolatile memory are provided on the back (non-light receiving surface) of the solar cell module, and an I / O connector (with The same dark gray exterior color as the solar cell module) is fixed on a predetermined portion without solar cells outside the power generation area on the light receiving face of the solar cell module.

[0239] In addition, a small battery and a comparator are provided in the solar cell module. The small battery here is used to operate the control circuit and comparator. Therefore, it is possible to store information in the nonvolatile memory without supplying electric power from the outside through the I / O connector. Here the comparator is used to monitor the voltage and current generated in the solar module.

[0240]In this example, the optimal operating point of the solar cell module used is found under the condition of 1 sun (...

Abstract

A solar cell module or a solar cell module which is provided with a readable and writable memory medium capable of writing in a large quantity of information of said solar cell module and capable of reading out necessary information from said memory medium. A solar cell system comprising said solar cell module or said solar cell module string. A method for supervising said solar cell module or said solar cell module string.

Description

technical field [0001] The invention relates to a solar cell assembly with a readable and writable storage medium, a solar cell assembly row comprising a plurality of solar cell assemblies and having a readable and writable storage medium, and a solar cell assembly with the solar cell assembly or the solar cell assembly Column solar cell system. The invention also relates to a method of monitoring the solar module or the solar module string. Background technique [0002] In recent years, social awareness of environmental and energy issues has grown worldwide. In particular, it has been foreseen that atmospheric CO 2 Increased warming of the planet by the so-called greenhouse effect can cause serious problems. In view of this, it is required to be able to provide clean energy without causing CO 2 The calls for cumulative power generation installations continue to grow. In this regard, considering that nuclear power generation does not cause CO 2 accumulation, nuclear po...
