A solar panel with no load isn''t connected to any devices. 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 become heat in the solar cells and radiate from the panel until it dissipates.
