This paper presents a method to quantify the solar irradiance by using an all-sky imager with a fish eye lens. This uses data sampled in Singapore, with variations in cloudy scenes, and is aimed at better prediction of photovoltaic energy production. This paper describes a model by which a sky image’s individual pixels, from compressed jpg, are used to related to a The paper is mostly well written, and concise, bordering on too short. The approach is interesting, and the applications may be wide ranging for energy forecasting. That said, the model is not well described, with major issues concerning the non-linearity and the normalization factor, that seems to make the model results look better than actuality. Model here is also a bit of a stretch as it is simply an empirical fit of the measured values. The actual evaluation of the model requires a normalization
