When a solar PV system is deployed for practical applications, the IV Charateristics keeps on changing with insolation and temperature. In order to receive maximum power the load must adjust itself and accordingly to track maximum power point. The voltage at which PV module can produce maximum power is called ‘maximum power point’ (or 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 day. Solar charge controllers are having wide range applications like in street lighting, water pumping system and many other industrial purposes. This paper mainly gives idea about designing of solar charge controller using maximum power point tracking system.
