The projects, each with 20MW capacity, include Hongyuan Huanju Ecological Energy and Ruoergai Huanju Ecological Energy.

Construction on the solar plants is currently underway and the Hongyuan project already has 2MW connected to the grid utilizing SunPower’s LCPV tracker, which combines single-axis tracking technology with rows of parabolic mirrors, reflecting light onto SunPower Maxeon cells.

The solar projects are expected to be completed in the fourth quarter of 2015.

Upon completion, the projects will be co-owned by Sichuan Shengtian New Energy Development, SunPower’s project development joint venture, and Apple.

The projects will feature SunPower’s light-on-land approach, which will allow pasture farming while power is generated.

SunPower president and CEO Tom Werner said: "These projects will provide clean, renewable energy, help address climate change, and continue to provide agricultural benefits to the local farmers, while protecting the area’s precious land.

"We continue to value our partnership with Apple and commend them for their global environmental commitment."

SunPower has already provided its solar solutions to Apple on six US projects totaling 90MW in California, Nevada and North Carolina.
