The power grid supply is always challenged by external factors that may significantly decrease its ability to be able to provide the amount of energy required, therefore making the system unreliable. Many infrastructure relies on the energy provided by the power grid supply and they may malfunction or stop functioning altogether if the energy provided is insufficient. Among these infrastructures, the ones that are most affected by this behavior are the communication infrastructures. The continuity of the communication services is therefore at risk and new ways to make the system more reliable must be found. A possible solution is to supply them through Renewable Energy Sources (RES), particularly Photovoltaic (PV) panels.
