Array Technologies has remained top of the IHS tracker rankings in 2014 with First Solar moving from eighth to third.

The thin-film module manufacturer and project developer increased its market share by 8.5%. Array and Sunpower continued in the top two slots despite losing 20.4% and 1.3% respectively of their market share.

In total, the global tracker market increased 60% to 4GW in 2014 with major vertically integrated players increasingly using their in-house trackers.

“As the United States was the biggest market for trackers in 2014, and with some of the largest tracker companies headquartered there, it is no surprise that the leading suppliers have such a dominant market share,” said Cormac Gilligan, senior analyst, solar supply chain, IHS Technology.

The fifth-placed company Soitec, chose to leave the solar market at the end of 2014. IHS suggests that 2014’s fourth placed firm NEXTracker could be set to make a bigger impact on the tracking market.

“Not only has NEXTracker been a successful preferred supplier of trackers for SunEdison, a leading global EPC player, the company has really embraced the global PV market by shipping its trackers to Chile, Australia and other international markets outside of the United States,” Gilligan said.

Array Technologies’ funder and CEO Ron Corio said the company was gearing up its production capacity for 4GW of annual demand on the back of recently launching its latest single-axis tracking system, the ‘DuraTrack’ HZ v3 for utility-scale PV power plants, which was claimed to significantly reduce costs and maintenance.
