There are different options:
Pour the spare energy into the network: It is the most economical option since it does not need the installation of any additional component. The electricity poured will not be remunerated by the electric company.
Install a zero injection system: This system will regulate the operation of the inverter to adjust to electricity consumption and will prevent it from overpowering and spilling into the electrical grid. In the case of hybrid panels, all the energy that is not produced in the form of electricity is produced in the form of heat, increasing the performance of the thermal part.
Install accumulation batteries: With this solution, the excess electrical energy is stored throughout the day to be used at night. This together with a contract with time discrimination will allow us to maximize energy savings. The initial investment will be greater than in the two previous options.
