Obviously, a huge portion of the most significant challenges facing the world today is reducing dependence on fossil fuels and advancing the development of new and renewable energy sources that can supplement and, where applicable, replace the dwindling fossil fuel reserves. Solar energy stands out as a particularly promising solution to these issues, as it is renewable, non-polluting, and universally available, albeit with varying levels of intensity. Ray tracing is a crucial tool for designing receiver systems in elliptical-hyperboloid concentrators (EHC). Information about flux distribution and ray tracing on the EHC receiver is crucial for determining the receiver's size using OptisTM Ray-trace software. This study examines the effects of changes in the sun azimuth angle on the EHC receiver's flux distribution. Obviously, the solar energy source is traveled via the primary axis of the aperture's x-y plane, ranging between 0° and 90° in 15° increments. A maximum optical efficiency is noted for every azimuth angle, which rises since the solar source is shifted between 0° to 90°. The findings also show how concentrated radiant energy is distributed throughout the receiver/absorber region that can supplement and, where applicable, replace the dwindling fossil fuel reserves.
