CSun did not disclose the terms of the agreement.
The Nanjing-based manufacturer expects to deliver polycrystalline modules for a number of rooftop and ground-mount projects that KosiFrankensolar is developing throughout Turkey this year.
CSun opened a 300MW PV factory in Istanbul last year.
In April, the Nasdaq-listed company reported that it shipped 577.4MW of PV modules in 2013, up 47.7% on the year, as Asia surpassed Europe as its primary source of demand.
