    IHS: Why 2014 PV installation forecasts are all likely to be wrong

    By Ash Sharma - 28 January 2014, 10:58 | 1

    Each year forecasts for how much new PV capacity will be added around the world are released. These are subsequently revised, updated, defended and invariably increased. The forecasts for 2014 from various banks and research firms however are quite different. The difference between the high-end and the low-end of expectations is massive – potentially 15GW – or put another way nearly half the amount installed in total the previous year.
