The Hartwell solar plant is located in Northamptonshire, England.

Commissioned in March 2015, the solar plant exports power to the local 33kV distribution network and is constructed using Q-Cells PV modules for a peak capacity of 18.6 MW.

Lark Energy is the EPC contractor. The project has a 25-year site lease and planning permission is in place for an equivalent period.

Revenues are derived from a mixture of ROCs (expected at 1.4 ROCs per MWh), LECs and power sales.

The site has been sold to a major international infrastructure investor and is no longer managed by Armstrong.
