In 2014, China settled on a new methodology for calculating cumulative capacity, which assumes a 10-year lifetime for Chinese-made systems. China and world data reflect this change.

India data are by fiscal year rather than by calendar year.
Note: Countries are ordered according to newly installed glazed water collector capacity in 2015. Data are for glazed and unglazed water collectors excluding air collectors, which add almost 1.64 GWth to
the year-end world total for 2014. Numbers are rounded: end-2014 data for individual countries and total top 18 countries are rounded to nearest 0.1 GWth, and world totals are rounded to nearest 1 GWth;
additions in 2015 for individual countries and total top 18 countries are rounded to nearest 1 MWth, and world additions are rounded to nearest 100 MWth. “~0” denotes capacity below 50 MWth. Where
totals do not add up, the difference is due to rounding. By accepted convention, 1 million square metres = 0.7 GWth. The year 2014 is the most recent one for which firm global data on total capacity in
operation are available. It is estimated, however, that 435 GWth of solar thermal capacity (water collectors only) was in operation worldwide by end-2015. For more information, see Solar Thermal Heating
and Cooling section in Market and Industry Trends chapter and related endnotes.
