Abstract

Solar radiation is a fundamental aspect of renewable energy and plays a pivotal role in various natural and technological processes. This paper aims to elucidate the physics principles underlying solar radiation, exploring concepts such as the solar spectrum, interactions with the Earth's atmosphere, and the mechanisms of absorption, reflection, and transmission. By comprehensively understanding these principles, we can optimize the harnessing of solar energy for applications ranging from photovoltaics to solar thermal systems, ultimately contributing to sustainable energy solutions.
