- FIG. 5 shows, as a comparative example, the voltage and output characteristics of one half cell divided into two as a solar cell, and the voltage and output characteristics when two half cells are connected in parallel.
- the output when connected in parallel is the total output of each solar cell at the same potential. As shown in FIG. 5, when half cells divided into two halves are connected in parallel, since half cells exhibiting the same voltage and output characteristics are connected, the output when connected in parallel simply doubles. Since a half cell with a maximum output Pmax(h) of 2.985 W was used, the maximum output Pmax(1) when connected in parallel was 5.968 W, approximately twice that of the half cell.

In order to prevent damage to the terminal box more reliably, the installation position of the terminal box is better the further away it is from the center line C, but the distance from the center line C increases. That is, when the length ratio L1/L2 of the short sides of the first solar cell 301 and the second solar cell 302 decreases, the maximum output Pmax of the solar cell module 1 tends to decrease.
- the purpose of forming a solar cell module by connecting divided cells in parallel is to suppress the decrease in FF and increase the maximum output (Pmax) of the solar cell module.
- the parallel connection part 50 should not be provided on the center line C, that is, the length ratio L1/L2 of the short sides of the first solar cell 301 and the second solar cell 302 ⁇ 1 is required.
- L1/L2 ⁇ 0.17 it is preferable that at least L1/L2 ⁇ 0.17 in order to obtain a higher maximum output (Pmax) than a solar cell module using undivided solar cells.
- the length L1 of the short side of the first solar cell 301 in the first direction D1 and the length L2 of the short side of the second solar cell 302 correspond to one side of the reference cell 30 having a substantially square shape.
- L L1+L2 and 1>L1/L2 ⁇ 0.17.
- L1/L2 ⁇ 0.33 because the rate of decrease in Pmax increases when the length ratio L1/L2 is less than 0.33. More preferably, L1/L2 ⁇ 0.8, which is comparable to the maximum output Pmax when a half cell is used.
- the terminal boxes 60 and 61 can be provided away from the vicinity of the center line C where the amount of deflection is large in the solar cell module 1, and damage to the terminal boxes 60 and 61 can be prevented.
- the maximum output of the solar cell module 1 can be set to a value higher than that of a solar cell module using a full cell, it can be suitably used for recent large-sized solar cell modules. .
- the optimum position for the position of the parallel connection portion 50 depends on the installation environment (wind speed, amount of snowfall, etc.) such as how much load is applied to the solar cell module 1, and the solar system related to the manufacturing cost. It depends on the size of the battery module 1 (for example, the larger the size, the larger the amount of deflection even with the same load) and the height of the frame. It is preferable to determine the value of L1/L2 in view of the relationship between the property and the maximum output (Pmax) of the solar cell module.
- the solar cell module 1 is not limited to the configuration shown in the embodiment.
- the first photovoltaic cell 301 and the second photovoltaic cell 302 provided in the photovoltaic module 1 may be single-sided light receiving type or double-sided light receiving type.
- the number of arranged first solar cells 301 and second solar cells 302 is also not particularly limited, and a desired size (L) of the solar cells before division can be applied.
