Solar resource: DIRECT NORMAL IRRADIATION (DNI) - this map provides a summary of the estimated solar energy available for power generation and other energy applications. It represents the long-term average of daily/yearly totals of direct normal irradiation (DNI). The underlying solar resource database is calculated by the Solargis model from atmospheric and satellite data with 15- or 30-minute time step. The effects of terrain are considered at nominal spatial resolution of 250 m. DNI is the most important parameter for energy yield calculation and performance assessment of concentrating solar power (CSP) and concentrator solar photovoltaic (CPV) technologies. DNI is also important for the calculation of global irradiation received by tilted or sun-tracking photovoltaic modules.
