Optimum Off-Grid PV System Sizing9 Case of Study: Aswan Egypt

摘要

During the last years, the electrical loads in continuously increasing. So, the electricity distribution companies stop feeding the electricity to customers who far than the distribution network and recommend using an off grid solar energy system. Now days, many of remote homes, farms, rest area and coffees are going to use off grid solar energy. Many initiating companies start supplying and installing off grid solar energy systems for such these places, but unfortunately there are a lot of problems that badly effected on the system performance and leads to partially or fully blackout of the system. These problems aren’t related to the nature or weather conditions, but they related to the design, calculation and selection of system components. This paper submits a correct model for design, calculations and selection of off grid solar energy systems and it is considered a guide for Micro-Scale off grid PV system.
