Solar energy estimation using REST model for PV-ECS based distributed power generating system

The effect of two important atmospheric factors, variation of turbidity and NO2 absorbance, is proposed in estimating the solar irradiance. Reference evaluation of solar transmittance (REST), a broadband model for the solar irradiance, is used to estimate the solar irradiance. After estimating the solar irradiance for the distributed power generating system, the photovoltaic (PV) solar output power is calculated. Instead of conventional batteries, use of a new storage device called energy capacitor system (ECS) is proposed because of its various advantages.
