Building on their 30 MW partnership announced last year, China-based Yingli and Poland’s R.Power, formerly AMB Energia, have said they will build 60 MW worth of ground-mounted solar PV projects. It is expected that the systems will be included in Poland’s 2016 and 2017 auction systems. Under the terms of the agreement, both parties will hold a roughly equal stake in the projects, which will be sold off to investors once they reach commercial operation.
