On the parallel connection of solar cells

if this group of bad The phenomenon of short-circuit, that the solar cells on the electrical equipment and output, but the voltage is reduced; if it is a parallel combination, then I suggest Each group of "output" line in series with a "switch" type of diode, so, if in which one of the short-circuit damage, other normal solar cells will not be bad on this group of "anti-charging" and Damage to other normal solar cells, if this group of bad conditions for the open circuit, it is only to reduce the entire solar cell "external" output current, will not cause other failures.

As for the solar cells in the string, parallel combination is Causing the damage of the battery pack, I think it is first necessary to make sure that the "combined" solar cells should have the same characteristics, and that the various parameters between them should be the same or similar, at least several major parameters must be the same, to achieve these Conditions can be combined after the combination; if the series combination in the use of a group of solar cells damaged and broken, then the other groups will not power the power supply equipment, because the entire line has been in the open state,

Whether you say more than one solar cell is in series or parallel, it depends on your use requirements to decide if the parameters of solar cells are basically the same, and you need a relatively high "use" voltage, that can The battery in series, if you need a larger operating current and the voltage does not need high, you can connect multiple solar cells in parallel to get a higher output current;
