Solar panel question

Here's one for you solar experts:

1. Will it cause any damage to a panel to momentarily short its output?

2. Will it cause any damage to a panel to leave it open circuit (no connection) for a period of time.

Both questions assume panel is in bright sunlight.

Thanks for the input in advance.

Re: Solar panel question

1. No.

2. No, but it would be better to leave them in open circuit for long term as there would be less heating going on.

You're welcome.

Re: Solar panel question

Concur - 'no' to both questions, open creates a bit less heat. Do keep in mind that the panel WILL get quite hot in full sun whether open circuited, shorted or working into a battery - not a problem, just something to keep in mind..

Re: Solar panel question

Concur with both posts above.


On a personal level, I prefer not to short out any source of power, even though solar panels are the exception, I still can't bring myself to do it.

Start small.
Try shorting out a solar panel in the dark, then work up to moonlight, then....

Re: Solar panel question

If you are going to leave solar panels unused for a length of time, leave the leads disconnected, but more importantly, cover the panels. A piece of heavy aluminum foil would reflect heat & light. A towel or piece of foam mat with something opaque over it would be a little better.


But it is pretty hard to insult a solar panel by just ignoring it.
