If solar panels cannot dispose of their generated electricity, this can lead to overloading of the electrical grid or problems with the operation of the solar panels themselves. When the panels produce more electricity than the connected system can handle, this can result in an excess of power.

In some cases, solar panels have inverters that convert the direct current they generate into alternating current, suitable for the electrical grid. However, if too much electricity is produced and the inverter is unable to process it, the system may shut down or show malfunctions.

To prevent this problem, control mechanisms such as grid connections and smart meters are often used. These systems can feed excess electricity back into the grid or store it in batteries for later use. If these mechanisms are absent and the excess power is not dissipated, it can lead to technical problems and reduced efficiency of the solar panels.
