Abstract
Description
technical field
[0001] The invention relates to a solar cell. Specifically, it is a warning device used to prevent short-circuiting of solar panels. Background technique
[0002] It is well known in the solar cell production industry that at present, only a solar cell group is arranged on a solar cell panel, and the solar cell group is composed of a plurality of solar cells connected in series in the same direction. During the use of the solar battery pack, if it is covered by leaves or clouds, it will not be able to generate electricity normally. Due to the internal resistance in the solar cell, when it is covered by leaves or clouds, it is easy to generate heat, which makes the battery pack easy to burn out. Contents of the invention
[0003] The problem to be solved by the present invention is to provide a solar battery panel short-circuit warning device. By adopting the short-circuit warning device of the solar battery panel, the situation of burning out of the batt...

Embodiment Construction
[0011] Such as figure 1 As shown, the solar cell panel short-circuit warning device of the present invention includes a first solar cell group 1, a second solar cell group 2 and a third solar cell group 3, and the first solar cell group 1, the second solar cell group 2 and the third solar cell group The third solar cell group 3 is composed of 24 solar cells 4 connected in series in the same direction. Both ends of the first solar cell group 1 are connected in parallel with a first diode group and a first indicator light R1, and the first diode group is formed by connecting a first diode D1 and a second diode D2 in parallel. 1. The anode and cathode of the first diode group are respectively connected to the cathode and anode of the first solar cell group 1 . Two ends of the second solar battery group 2 are connected in parallel with a second diode group and a second indicator light R2; the second diode group is formed by parallel connection of a third diode D3 and a fourth dio...
