As part of the agreement, Yingli has delivered about 40,000 PV modules by the end of February 2014 that will be installed on the Isle of Sheppey, which is 85km east of London.
The project will generate about 10,000MWh of electricity per year, enough to power 3,000 typical homes.
Solarcentury COO Matthew Boulton said, "Solarcentury looks back on a strong partnership built on trust with Yingli Green Energy for more than five years with the intention to deepen the collaboration moving forward."
Yingli Green Energy UK Business Development director Ramin Dilmaghanian said, "As a strategic partner in the UK, we look forward to continuing our cooperation with Solarcentury, a company that has been around since the early days of the solar industry.
The plant is being purchased by the Bluefield Solar Income Fund (BSIF).
