The projects are currently at various stages of development and have a potential build value of approximately £200m ($340m).
Lumicity chief executive officer Tristan Fischer said: "Partnering with Conergy is great news for Lumicity’s customers and will ensure the projects will be built quickly and to the highest standards."
The new 21MWp power plant will be built by Conergy UK & Ireland in the suburbs of Bristol, the largest city in south-west England.
The power plant is expected to produce enough electricity to power the equivalent of 3,750 homes, while avoiding carbon dioxide emissions of close to a quarter of a million tons, over the expected 25-year lifetime.
Conergy global COO Alexander Gorski said: "Lumicity has a strong record in the development of renewable energy projects, and the deal supports both Conergy’s power plants strategy and the expansion of its international pipeline."
