摘要

<span style="font-family:Verdana;">This work presents the results of the characterization of a standalone photovoltaic system for the electrification of a household located in rural area in the western region of Cameroon: Nziih-Bafou in Dschang (5.35</span><span style="white-space:normal;background-color:#FFFFFF;font-family:Verdana;">°</span><span style="font-family:Verdana;">N, 10.05</span><span style="white-space:normal;background-color:#FFFFFF;font-family:Verdana;">°</span><span style="font-family:Verdana;">E and 1900 m). In order to cope with the</span><span "=""> </span><span style="font-family:Verdana;">maintenance charges and reduce the investment cost, a small mill was added to the appliances of the household for income generation. The assessment of the energy demand was made by taking into account the reactive energy due to the heavy</span><span "=""> </span><span style="font-family:Verdana;">consumption of energy by the mill’s motor, especially during ignition. The sizing of all the system’s components was carried out with the prospect of determining an optimum design in accordance with daily electricity demand, site irradiance profile and climatic conditions. In this context, tilt angles applicable to the PV structure and that allow</span><span "=""> </span><span style="font-family:Verdana;">to receive the maximum irradiance as a function of the periods of the year were determined using the Hay model.</span><span "=""> </span><span style="font-family:Verdana;">This approach provides the system with incident irradiance greater than or at the limit equal to that received by a horizontal surface on the same site</span><span "=""> </span><span style="font-family:Verdana;">compared to the case of a single tilt angle where the irradiance on the inclined plane is often lower than that</span><span "=""> </span><span "=""><span style="font-family:Verdana;">on the horizontal. The economic analysis of the PV system showed an </span><span style="font-family:Verdana;">initial cost of $4448</span></span><span
