Architecture of Solar Pump system

Architecture of Solar Pump system :

• The performance of a solar water pumping system consists of a photovoltaic (PV) array, Motors; it can be Submersible or Surface. The efficiency of the system is improved with Maximum Power Point Tracker (MPPT).
• The MPPT (VMPP search) will change the set point value in order to search the maximum power of the photovoltaic panel. The maximum power point depends on the panel temperature and the solar irradiation.

Sudden change in the DC bus voltage, caused by a fast change on the irradiation condition (for example from/to cloudy conditions). The Controller is suitable to follow the actual DC bus voltage by a multiplication factor.
