FREQUENTLY ASKED QUESTIONS

WHAT IS SOLAR RADIATION DATA?

Solar radiation data is a measure of the amount of solar energy received at a particular location over a specific period. This data encompasses various parameters, including solar irradiance, which is the power of sunlight per unit area, typically expressed in watts per square meter (W/m²). Solar radiation is crucial for determining solar energy potential, essential for designing solar panels and photovoltaic systems. Different types of solar radiation measurements exist, such as global horizontal irradiation (GHI), direct normal irradiation (DNI), and diffuse horizontal irradiation (DHI). GHI combines direct sunlight and scattered light, DNI measures solar energy received directly from the sun on a surface tracked towards it, while DHI accounts for sunlight that has been diffused by atmospheric particles. Accurate solar radiation data plays a vital role in energy planning, helping developers and researchers assess the viability of solar energy projects, predict energy output, and optimize installations for maximum efficiency. With the increased focus on renewable energy sources, solar radiation data has become indispensable for advancing solar technology and meeting future energy demands.

WHERE CAN I ACCESS SOLAR RADIATION DATA?
