What Happens if a Solar Panel is Not Connected to Anything?

Of course when the sun goes down you can no longer use the solar panel power, not unless the energy was stored in a battery bank. The situation is comparable to a battery. A fully charged battery – the Vmaxtanks 125ah AGM is a good example – can power several appliances and devices, but it must be connected to a load.

Don''t Short Circuit A Solar Panel (Do This)

A short circuit happens when an excessive current runs through an unintended path – you overload the system. Yes, you can short a solar panel, but you likely won''t cause damage to the panel in this way. A solar panel is rated by its short circuit current and was likely shorted during testing.
