Estimation of solar radiation on inclined surface and design method for an autonomous photovoltaic system. Application to Algeria

Algeria has a large solar energy potential (the first in the Mediterranean Sea). This deposit makes it suitable for the installation of solar energy conversion systems, especially photovoltaic (PV) systems. The design of these systems is an important step, its optimization, as well as optimization of the various parameters of the system, is a crucial step. In our work, after estimating hourly solar radiation, we have optimized the design of a photovoltaic installation in the region "Zenata" (Tlemcen), western Algeria, focusing on the panel´s efficiency, total capture area, and total battery capacity. We used the concept of hourly solar usability to develop a design method through several stages.
