Introduction
Data on sun irradiation is required at every stage of solar power development, from the early stages of government planning through the creation of large-scale projects or the calculations required to size smaller systems.
In the past, such information had been supplied by other international sources at a relatively coarse level.
Still, more recently, specialized models have been created to calculate direct and diffuse irradiation (GHI) and monthly average daily radiation exposure (DNI) using mainly satellite cloud protection data.
Such data are now made available as a paid service by several businesses. This allows for calculating the average yearly power output (POUT) from a hypothetical Best Solar company in Rajkot plant while accounting for heat, tilt, and the effectiveness of the device being employed.
