When a solar panel is disconnected from any loads, it absorbs sunlight but does not use or distribute the produced electricity to the connected devices. The panel retains voltage which gets converted
Energy generated by an unconnected solar panel is wasted as heat within the panel, causing efficiency loss and potential damage. Without a load, voltage buildup occurs, leading to heat generation,
It is true that some CdTe (cadmium-telluride) panels can be damaged if left without a load in the sun. As a practical matter, it is not an issue for your silicon based panels.
What Happens to The Solar PanelsIs It OK to Let The Solar Panels Get Hot?Is It OK to Leave A Solar Panel Disconnected?Is It Necessary to Unplug Solar Panels?What Happens to Excess Solar Power generated?Should I Cover Solar Panels When Not in use?ConclusionSolar panels are not perfect, but they are among the safest power sources available today. As long as the connections and installation are done right and the system is not overloaded, you do not have to worry about something untoward happening.See more on portablesolarexpert NAZ Solar Electric Forum

Solar panels are current-limited voltage sources. Their output depends on sunlight, temperature, and the electrical load connected to them. Importantly: If no load or a limited load is present, the panel voltage rises
When not connected to a device, a solar panel will still absorb sunlight but won''t have anywhere for the energy to go. It has voltage, but no current is flowing. Because the voltage has nowhere to go, it will
Although many researchers have focused on determining the specific flow characteristics of wind loads on solar panel arrays, the effects of wind loads on floating PV systems have not yet been sufficiently
Most distributed PV systems automatically shut off during a grid outage, resulting in zero resilience benefits (i.e., the panels are undamaged, but power is not available during a grid outage).
If there is no circuit, the solar panel will just “sit there” as the photons will not be converted into electricity. The panels will get hotter true, but the modules are going to get hot anyway if you connect a load to it.
Once a solar panel is left out in the sun for too long without a load, it can get damaged. There''s nowhere for the power to flow and, without a regulator, the current can overload the system.
