Solarcentury utilized the modules in its ground-mounted solar projects and large commercial rooftops in the UK.
The company will install about 49MWp of JA Solar’s Full Square mono 275Wp modules for the Southwick solar farm.
The Southwick solar farm is expected to be connected to the grid in March 2015.
Solarcentury CEO Frans van den Heuvel said: "We are pleased to be working with JA Solar for our UK builds; increasing the UK’s solar energy capacity also improves energy independence and reduces reliance on foreign imports."
JA Solar chairman and CEO Baofang Jin said: "The UK market remains very successful for JA Solar and we have seen continued growth year after year.
"Despite an impending renewables obligation (RO) limit to individual PV sites over 5MWp, we are still optimistic about the UK market in 2015.
"The UK PV industry is extremely dynamic with strong fundamentals. We see the market maturing at a fast rate, and any gradual shift of focus towards rooftop solar also lends well to our strategy for higher powered products."
