Problems solved by technology

In this method, since the disc-shaped semiconductor single crystal wafer is cut and formed into a quadrangular shape, there is a problem that crystal loss in an arcuate shape occurs.
Even if it is set in small blocks, if the total 12m 2 If the solar power generation system of the unit is set on the roof, there will often be a dead zone where modules cannot be configured (non-configurable parts)
Furthermore, one module weighs 15kg, making it difficult to install on the roof

Abstract

The aim of the invention is to provide a sunlight power generating module which has no loss of the circular monocrystaline wafer and can highly uses the arc battery that is not effectively utilized to this day and a sunlight power generating system using the module, a sunlight power generating module which provides high actuating electric voltage (''area voltage'') in each unit area and the sunlight power generating system using the module, a sunlight power generating module which can increase the configuration ratio of the module relative to the effective setting area of the residence roof and the sunlight power generating system using the module. The sunlight power generating module is composed of arc battery divided by the circular monocrystaline sunlight power generating battery, the arc battery has an arc with neutral angle 90 degrees, a grill orthogonal with the string and more than one generatrix orthogonal with the grill, and the arc battery is arranged to grill shape, and the sunlight power generating module is characterized in that the 14-42 pieces of arc battery with area 28-65cm<2> are arranged.

Description

technical field [0001] The invention relates to a solar power generation module and a solar power generation system formed by arranging a plurality of monocrystalline silicon solar power generation cells. Background technique [0002] Until now, cells for photovoltaic power generation (also called "solar cells" or "batteries") have been manufactured from rectangular polycrystalline silicon wafers obtained by slicing rectangular parallelepiped polycrystalline silicon ingots. Solar cells using semiconductor single crystal silicon wafers have higher energy conversion efficiency than solar cells using polycrystalline silicon or amorphous silicon. In addition, single crystal silicon wafers are also relatively cheap, so they will become the main force of popular solar cells in the future. At this time, a solar cell is manufactured using a disk-shaped wafer obtained by slicing a cylindrical ingot. [0003] For example, a semiconductor single crystal obtained by Czochralski single ...
