Abstract: The limited resources and high cost of conventional energy sources like oil, gas, coal, as well as the continued environmental pollution are some of the main reasons for wide spread introducing of renewable energy sources in electrical power systems. The development and usage of these alternative energy technologies are still restricted. Solar energy has the greatest potential of all the sources of renewable energy. This work deals with the design and simulation of a simple but an efficient solar photovoltaic PMDC water pumping system. The system employs the Maximum Power Point Tracker (MPPT). The 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. And then PV model parameters are calculated, analyzed and compared with the simulated values. The design offers lower system cost due to use of fewer sensors on the output sensing, direct control technique. The MATLAB simulations verify the system and functionality of MPPT. Simulations also make comparison with the system without MPPT .This method is best suited for developing countries like India to fulfil their electric power network in rural areas.
