Photovoltaic system is an important topic that can be researched and studied in Palestine because a solar energy potential is available. This thesis deals with the design and simulation of an efficient standalone PV system for an electrical home loads. It provides theoretical study of photovoltaic and modeling techniques using equivalent electric circuits. The research includes discussion of various MPPT algorithms and control methods to maximize the obtained solar power. Simulations by Matlab Simulink to verify the DC-DC converter design with MPPT control to be efficient as battery charge controller is investigated. The best inverter model that would be chosen for generating a sinusoidal output current supply for a household load is discussed. This thesis selects a 4.5kWh-day energy load for a household as a case study to find the optimum design and configuration. The system is comprised of polycrystalline PV modules each rated at 130W to obtain a total peak power of 1.56 kW. In addition, one inverter of 3 kW and battery storage of 11.7 kWh is included in the system. Design of a grid tie PV system by using matlab Simulink and testing the dynamic behavior on this system at varying solar radiation is included in this thesis. Based on the economic evaluation, the cost of energy generated by a standalone PV system were studied is 2.1 (NIS/kWh) while the cost of energy generated by grid tie PV system is 0.72(NIS/kWh).
