What is the purpose of a maximum power point tracker (MPPT) in a PV system?

Explanation:

• A Maximum Power Point Tracker (MPPT) is a device used in photovoltaic (PV) systems to ensure that the solar panels operate at their maximum power point (MPP), which is the point at which they produce the highest possible power output.
• The purpose of the MPPT is to continuously adjust the electrical operating point of the PV system (voltage and current) to ensure that the system extracts the maximum power under varying conditions such as changes in sunlight intensity, temperature, and load. 
• MPPT helps optimize the energy conversion efficiency of the PV system by tracking the optimal voltage and current at which the system delivers the most power. 
• In summary, the primary function of MPPT is to maximize the electrical power output of the PV system by operating the panels at their most efficient point.
  
  Additional Information​ 
• MPPT is abbrvated as Maximum power point tracking algorithm
• This algorithm used to extract maximum power from the renewable source like solar energy
• To gain the maximum amount of power from the solar cell it should operate at the maximum power voltage. The maximum power voltage is further described by VMP, the maximum power voltage, and IMP, the current at the maximum power point.
• The maximum power point (MPP) is the point on the current-voltage (I-V) curve of a solar module under illumination, where the product of current and voltage is maximum (Pmax, measured in Watts).
