Design and Development of A PV / AC Grid Hybrid System in Rwanda

This project focuses on the design and development of a Solar Pv/Ac Grid Hybrid System in Rwanda supply the electricity in different houses. The solar PV /AC Grid Supply Hybrid System supply electricity to any installation by using two different source of electrical energy which are the solar PV source and national grid source control system to interchange those two supply system according to the voltage. The researcher chose a survey research design because it best served to answer the questions and the purposes of the study. The survey research is one in which a group of people or items is studied by collecting and analyzing data from only a few people or items considered to be representative of the entire group. It principle operation is that this system at the beginning, it will be using electricity from solar PV as default supply for the installation , once the PV electricity become insufficient (mean when PV battery reach at their death of discharge) there will be an automatic and intelligent switch which will cut off the electricity from solar PV and connect my installation to the AC national grid supply system and again when the electricity from PV system become sufficient(mean when the PV battery are full charged) the electricity from national grid will be cut off and again the installation will be connected to PV solar system. This project will not only provide explanation of how to design a PV/AC Grid Supply Hybrid System it will also provide deep explanation about how to design, choose, sizing of all components, calculation and formula used in order to design the solar PV System.
