About What to do if photovoltaic panels short-circuit due to snow
This article discusses the defect mode of short-circuit strings, and the importance of robust site safety protocols. Strings in open versus short-circuit are simple to distinguish using aerial Infrared inspection, as demonstrated by the example given in Figure 1.

No - you will not damage a solar panel by shorting it. Solar panels are designed to be continuously operated at very very close to their short circuit current. A good quick test of a solar panel is to run it short circuited into an ammeter.
Reduced friction and adhesion between snow and PV panels can reduce loss when sliding is the mode of clearing. Friction relates to the interaction between snow and the PV panel. Adhesion is caused by the bonding strength of ice that forms at the interface between the panel and the snow.
You can also short circuit a solar panel intentionally! This is a standard diagnostic tool performed to test the maximum current at zero voltage. This is called the short-circuit current of a solar panel and it is one of two tests done to see if the panel is in good working order.
The Short Circuit is too low. So why does this occur and how do you fix it? Low Short Circuit Current issue is quite similar to Low Amp issues. There are generally three main causes, Environmental factors like Solar Panel Orientation, Internal Problems in Solar Panels like blown bypass diode, or Wrong Measuring method.

6 FAQs about [What to do if photovoltaic panels short-circuit due to snow]
Can You short circuit a solar panel?
Don't Short Circuit A Solar Panel (Do This) - Solar Panel Installation, Mounting, Settings, and Repair. If you’re asking about short-circuiting any electronic device, you’re probably worried that you’ve damaged your device in some way. A short circuit happens when an excessive current runs through an unintended path – you overload the system.
Can a solar panel be damaged by a short circuit?
In trying to measure the current output from a solar panel I've inadvertently short circuit the panel. Did I damaged the panel? How can I test if everything is ok? Does it still produce voltage when light is shone on it? I think the is high enough that it can't be damaged by short circuit. In fact, solar cells are rated by their .
What are the causes of short circuit current in solar panels?
There are generally three main causes, Environmental factors like Solar Panel Orientation, Internal Problems in Solar Panels like blown bypass diode, or Wrong Measuring method. Resolving these issues is fairly simple and can be done yourself or by taking help from experts. Let’s talk about short circuit current.
What happens if a solar panel is shorted?
A solar panel is rated by its short circuit current and was likely shorted during testing. If your panel was damaged after you shorted it, it likely means that the panel itself was defective in some way. If you’re worried about damaging or overloading your solar panels, here are some common issues to educate yourself on:
Is it OK to short a PV panel?
If the panels were robust and healthy, they are fine. Shorted panels produce Isc (amps, short circuit) and if there are some thin or defective traces, they may be damaged long term, but shorting a good PV panel should not hurt it, even for an hour. IMHO Shorting the panels is fine. It is a normal diagnostic exercise to short them and measure Isc.
How to test a solar panel?
Also before your test, don’t forget to clean your solar panel. Accumulated materials on a solar cell will mess up short circuit current output. And finally the orientation. Your panel should be at 90 Degree (Right Angle) with the incident light while testing. In a simple world, sunlight should hit the panel in a perpendicular manner.
