The panel retains voltage but does not create current because for electricity to exist in usable form, both voltage and current are required. The system remains in an open circuit condition, meaning it continues to absorb sunlight without powering any devices. As PV voltage is allowed to rise above Vmp, more and more of the illumination generated current is shunted across PV cells' inherent diode. . In a grid-connected system, excess energy is fed back to the grid, reducing the load on the local electricity supply and earning the homeowner bill credits through net metering. The cells in the solar panel will get hotter as the voltage increases, but the cell surface is large enough to handle the heat. But when neglected or left exposed for extended periods without care, that rate can speed up significantly.
