Explain the schemes available for extraction of maximum power from solar energy
What is MPPT? MPPT or Maximum Power Point Tracking is algorithm that included in charge controllers used for extracting maximum available power from PV module under certain conditions. The voltage at which PV module can produce maximum power is called maximum power point also known as peak power voltage. Maximum power varies with solar radiation, ambient temperature and solar cell temperature. Typical PV module produces power with maximum power voltage of around 17 V when measured at a cell temperature of 25°C, it can drop to around 15 V on a very hot day and it can also rise to 18 V on a very cold dayHow MPPT works? The major principle of MPPT is to extract the maximum available power from PV module by making them operate at the most efficient voltage (maximum power point). That is to say MPPT checks output of PV module, compares it to battery voltage then fixes what is the best power that PV module can produce to charge the battery and ...
