There is ~1000W/M2 of electromagnetic power from the sun, and if it's not turned into electrical power it will be turned into thermal power, thus heating up the panel.

So as long as manufacturers engineer their panels to be tolerant of the maximum heat at a site (i.e. full sun, maximum temperature), the panels won't be harmed in any meaningful way. They'll just heat up a bit faster than if they were providing current.
- sangnoir 2y agoIs ther a difference between "electromagnetic power" and "thermal power" here? If a panel is not connected, there is no conversion and the surface is warmed - just like any other surface exposed to the sun gets warmed. PV panels are just like charged capacitor or a chemical battery with no loads: just holding unused potential differences with no damage to the unit.
