Abstract:
The electricity demand is very high worldwide. The energy growing needs consideration of environment protection. Some alternatives have been taken such as using renewable energy. Peat, Thermal and Hydro are still in small scale in some African countries including Rwanda. Rwanda is under developing country and energy is the key component of the economy growth. The grid connection is less than the budgeted by the Rwandan Government, it is blocked by the country topography. The rural areas are the most suffered because some of them have means and continue to use traditional manners which results to the environment damages. They are some alternatives such as using photovoltaic system. It is in way this thesis is concentrating and looking on a design of a photovoltaic no connected to the national grid of 0.8 Kwh/day for a househo ld in Kamonyi District as a chosen case study. The goal of this design is to increase the number of household connected to off grid photovoltaic system. The first part of the design focused on analysis of electricity to be consumed by the household considering the appliance in the house. The second step of this design is the cost analysis of all needed components in order to involve the householder in the system design, costs of the system and let him have the character of ownership. The result of this design helps in sizing the PV panel, battery capacity and converter to provide the required electricity to the household. In this project the design and all simulation are done through PV SYSTEM V6.70 Software, excel software, books, scientific researches, survey, journals and different papers
