If solar panels cannot dispose of their generated electricity, this can lead to overload of the electricity network or issues with the functioning of the panels themselves. When the panels produce more electricity than the connected system can handle, it may result in a surplus of power.

In some cases, solar panels have inverters that convert the direct current they generate into alternating current, suitable for the electricity grid. However, if too much electricity is produced and the inverter cannot process it, the system may shut down or display malfunctions.

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