Hence Solar charge controller helps in increasing the efficiency of the solar power transferred to the battery. Photovoltaic modules show nonlinear output characteristics because of different system losses. Maximum power point tracking (MPPT) is an intelligent technique for reducing these losses by driving the system at its maximum operating point. DC/DC converter is an essential part of a MPPT controlled photovoltaic (PV) system which functions as an interface between PV system and the load. These Converters are mostly Dc Choppers which converts fixed Dc voltage to a variable Dc source. These Regulators are used in case of Solar Charge Controllers to increase or decrease the PV panel voltage to as that required by Battery. The DC voltage from the PV panel varies with the light intensity which depends on time of day and temperature. Similarly, on the Battery side the voltage varies depending on the load connections. Thus, for optimal charging of battery it is important that the voltage of the PV panel and the current matches the battery charging state at any instant. There are various types of Dc-Dc Converter of which Buck Boost Converter is taken into consideration. In this project work we propose an efficient photovoltaic system which will be designed, developed and the results will be validated in real time.
