Solar energy is the cleanest and most developed form of renewable energy. In order to be completely independent of the grid source we need to have off grid solar system. This thesis presents a model in which we have designed an off-grid DC solar system using homer pro. We have used 8 batteries, 36 PV modules to make a DC system that would be sufficient enough to provide the requirement of home with load of 7.81 kWh/day. We then designed two further systems with DC generator, PV and Battery bank. The Homer pro results for each case are elaborated in the thesis. Steady state as well as dynamic system modelling is included which are done on the MATLAB. We have designed MPPT(maximum power point tracker is an electronic DC to DC converter that optimizes the match between the solar array (PV panels), and the battery bank or utility grid) for capturing maximum power. Along with design and modelling, the safety measures are also given. The safety device, working principle and the method to use them is also discussed in the thesis. Presented results will help further in the design of small scaled off grid solar systems that would be sufficient to provide the electricity in the remote area and on the small scale. This research also will help in designing the solar system for the DC load.
