A solar backup system to provide reliable energy in presence of unplanned power outages

Unreliable power grids in sub-Saharan countries have forced households to seek on-site generation (self-generation) options. Although diesel generators the largest share of backup systems, use solar systems has been growing over years. This paper presents a system including PV panels, battery and hot water (SHW) provide both reliable energy households. Moreover, two different configurations studied improve system's performance. Whilst SHW is limited preheating electric first configuration, second it can individually for short-term uses cases lack energy. The equipped with an intelligent prediction-based controller that control flow temperature presence limitations unplanned outages. Evaluation proposed using real datasets shows addition delivering water, total cost solution project life about 25% lower than generator's, making more viable investment.
