How long builds take
Years since construction started for the units still being built, against the median time from construction start to grid connection for units that connected since 2010 in the same country. Worldwide that median is 6.6 years across 95 units. The median counts only builds that finished, so it leaves out any that are still running or were abandoned and flatters the comparison. A country with fewer than three such units has no yardstick, and its cell is left blank. A unit that has run longer than the median is not necessarily late or stalled: start dates are the tracker's, and designs and sites differ.
| Country | Units with a start date | Average years so far | Longest so far | Median to connect, since 2010 | Running longer than that |
