(28 February 2012, Hong Kong) GCL-Poly Energy Holdings Limited (“GCL-Poly”, “the Group”, stock code: 3800.HK), a leading solar equipment integrator, announces its first residential rooftop system at PV Expo Japan in Tokyo from 29 February to 2 March. The GCL-Poly’s residential rooftop PV system is designed to fit on a typical Japanese flat concrete rooftop. It is an easy-to-install kit which is composed of high-efficiency crystalline silicon modules, matching rack-mount components and a reliable inverter. The performance of the system is further enhanced with real time panel-level maximum power point tracking (“MPPT”) and system monitoring using Tigo Energy’s DC Maximizer solutions. Known for its upstream polysilicon and wafer production and downstream system integration and solar farm development capabilities, GCL-Poly plans to provide optimised solutions of integrated PV equipment in order to further enhance the product performance at system level, and drive down system cost through economy of scale and system standardisation. The residential rooftop system is one of the product series of solar system integration business of GCL-Poly. GCL-Poly’s drive to improve the quality of the crystalline silicon wafers sets a strong foundation for the continuous improvement of the efficiency of PV modules. By deploying higher efficiency PV modules, GCL-Poly residential system is able to harvest more solar power in space-constrained metropolitan rooftops. The integration of smart electronics in the system will also minimise the power loss caused by shading from closely packed adjacent buildings. As a result, GCL-Poly residential rooftop system will see a much wider application in the residential market.
