Forecasting PV market demand in European countries has at times been particularly challenging. Complications include demand being largely policy-driven, the lack of market caps, and downstream channels being adept in shifting high inventories rapidly to the end-market when motivated to do so. During the past two years however, means of forecasting end-market PV demand have improved considerably. The methodology can in fact be seen as an evolving process, and PV market demand in Greece can be used to explain these points.
