AS PER STUDIES, EXPERTS ARE BAD AT PREDICTING SOLAR INSTALLATIONS

As per an article published by Visual Capitalist, organisations such as IEA (International Energy Agency) and EIA (Energy Information Administration), which have been predicting data on energy supply and demand as well as their forecast have been facing a number of challenges. Also, it can be said that these organisations are conservative with their forecast.

As per the graph, there is a huge gap between the historic data and the predictions by the IEA. None of the models have been able to rightly predict the growth in solar installations.
