Abstract: The continued environmental pollution are some of the main reasons for their widespread introduction in electrical power systems. This work deals with the design and simulation of a simple but an efficient solar photovoltaic system. The system employs the maximum power point tracker (MPPT). Simulations verify the DC-DC converter design. This work includes theoretical aspects of photovoltaic (PV) cell with equivalent circuit diagrams and equations. MATLAB simulations perform comparative tests of two popular MPPT algorithms, called Perturb and Observe algorithm and Incremental Conductance method using actual solar irradiation data and temperature coefficient data. Under the natural atmospheric condition is considered for data. The design offers lower system cost due to use of fewer sensors on the output sensing, direct control technique. DC motor pump will be modelled by SIMULINK, and then model will be transferred into MATLAB. Then MATLAB simulations verify the system and functionality of MPPT. Simulations also make comparison with the system without MPPT in terms of total energy produced and total volume of water pumped per day. best suited for developing countries like India to fulfil their electric power network in rural areas.
