I generally like IEA stuff, but you also have to be careful about using them as a standalone source. The IEA WEO is infamous for its inaccurate solar capacity forecasts over the last 10-15 years. They repeatedly assumed annual solar additions would flatten out (i.e., future years will not see more additions than recent years), despite the roughly exponential growth that was obviously happening. After doing it 5 years in a row, you have to wonder what was going wrong…
