Description

This tool calculates the daily solar radiation (Rg) based on the date and the latitudinal position for incoming top of atmosphere radiation (R0) estimation and the sunshine duration (Sd) provided as percentage of its potential maximum (S0). It uses a simple empiric formula:
Rg = R0 * (0.19 + 0.55 * Sd/S0)
