Solar PV energy is one of the most economical and reliable renewable sources on the market today. The constantly rising price of electricity, together with the drop in the prices of the components that make up a photovoltaic installation, is resulting in a direct increase in the implementation of this type of solution in both industrial and urban environments by public entities, private companies and private users.
The architecture of the self-consumption system is based on the installation of a CDP controller that can monitor the energy generated and the energy demanded by the installation, such that the system can detect the amount of energy required and control the photovoltaic inverter based on the instantaneous demand.
If the energy generated is lower than that demanded by the loads on the installation, the system will combine energy from the PV installation and the grid. However, if the consumption of the installation is lower than the energy generated, the CDP controller will send a signal to the photovoltaic inverter to reduce generation to only that needed to cover the actual consumption, and avoid feeding the surplus into the distribution grid.
