FREQUENTLY ASKED QUESTIONS

WHAT ARE THE TYPES OF SOLAR RADIATION?

Solar radiation can be categorized into several types, primarily direct, diffuse, and reflected radiation. Direct radiation reaches the surface in a straight line from the sun, offering maximum energy potential, generally measured on a clear day. Diffuse radiation, however, is scattered by atmospheric particles and clouds, resulting in lower intensity. Reflected radiation arises when sunlight bounces off surfaces such as snow or water, contributing to overall solar energy capture, albeit in smaller amounts.

The distinctions among these types are paramount for various applications. For instance, solar photovoltaic systems are designed to optimize direct radiation. In contrast, calculating overall energy potential in a location involves considering both diffuse and reflected radiation to ensure comprehensive energy assessments.

HOW DOES LOCATION AFFECT SOLAR RADIATION?

Geographical positioning significantly impacts the quantity and quality of solar radiation received. Areas situated closer to the equator experience more intense solar radiation due to the sun’s rays striking the surface more directly. Conversely, regions near the poles receive sunlight at a lower angle, which translates into less energy absorption, particularly during winter months.

Elevation and local geography also alter solar radiation levels. For example, mountainous regions at higher altitudes generally receive increased solar irradiation compared to low-lying areas. Understanding these regional characteristics is essential for optimizing solar energy projects, enabling developers to harness maximum solar potential according to the unique climate contexts of their projects.
