See Methodological Notes on page 142. 2 Solar collector capacity is for glazed and unglazed water systems only (not including air collectors, which account for another estimated 3.6 GWth total at end-2013). Additions are net; gross additions were estimated at 57 GWth. Note that past editions of this table have not considered unglazed water collectors. Note: Numbers are rounded to nearest GW/GWth/billion litres, except for numbers <5, which are rounded to nearest decimal point; where totals do not add up, the difference is due to rounding. Rounding is to account for uncertainties and inconsistencies in available data. For more precise data, see Reference Tables R2–R10, Market and Industry Trends section and related endnotes.
