Guide: How to find "bus bar disconnection"
Technology Online posted the maintenance experience of a company called Chemitox. Usually, this type of article is written as part of a product or service introduction, but this article has no such promotion and is simple but good information.
Busbar contact failures and disconnections are typical of solar power generation
failures. Apparently, it was discovered by an AIST mega solar inspection last year.
The current panel may have been improved, but I think disconnection and poor
contact of the copper busbar manufacturers in India.

In this article, photos of burnt cells and broken panels due to poor busbar
contact are introduced and will be helpful.

It is desirable to find and replace such panels as soon as possible, but they are
difficult to find until they burn or crack. Although the article points out that
monitoring the power generation of the strings may help to detect them at an
early stage, I think that there are not many systems that can monitor each
string. In addition, if the contact is poor, string monitoring may overlook it.

Is it a practical discovery method to perform regular inspections (about twice a
year?) With a thermal camera? I go there only once a year, but so far there is no
problem.

At one point, some Japanese manufacturers' panels often caused poor contact
with the busbar, but that seems to have improved. The most important thing to
pay attention to is the low-cost imports. After all, is it worth the price? I think
that there are many such panels in the turret solar, so it is recommended that
those who are likely to inspect it regularly inspect.
