# Real-time estimation of solar irradiation

## Abstract

Aspects relate to methods, systems, and computer program products for estimating future levels of solar power received at a sensor including receiving, by a processor, a first measured power value at a first time from the sensor, calculating a first value of a dynamic correction factor based on the first measured power value associated with the first time, applying the first value of the calculated dynamic correction factor to a power estimation model, generating a first power estimation value for a second time using the power estimation model, wherein the second time is later than the first time, receiving a second measured power value at the second time, and calculating a second value of a dynamic correction factor based on the second measured power value associated with the second time and the first value of the dynamic correction factor.
