As the key partner, SunPower started to transfer diamond wire wafering technology to TZS in the fourth quarter of 2011. Between the second and fourth quarters of 2012, the SunPower team shared its resources with TZS in Hohhot, Inner Mongolia to help set up a new manufacturing plant with a capacity of 400 MWp.
In late 2012, DW wafers were supplied to SunPower solar cell manufacturing plants in both the Philippines and Malaysia at very competitive prices. Costs had been slashed by over 60% since the end of 2010.
