Guide Shorting a solar panel
A short circuit does not have any where for the energy to go (nothing external to the panel gets hot, nothing is moved)--So, from what I can see, no energy is removed from the panel. In any case, you are only, at best, removing ~10-15% of the heat as electricity from the panel--Generally, that would have very little cooling effect.

Guide Can you damage a solar panel by short circuit? :
When your panels are connected in parallel, the current is additive. So, if you have 4 panels each capable of up to 15 amps, then a short in one panel can draw all 60 amps towards that short-circuited panel. This will cause the wires leading to that panel to far exceed 30 amps, potentially causing a fire. In this case of panels wired in
