Greentec Co Ltd, a Japan-based system integrator of PV systems makes solar power affordable for all. The company has recently unveiled a photovoltaic power system whose price starts from $3,401. Exhibited at PV Japan 2010 in Yokohama City, Japan, the new PV system is made with amorphous silicon PV cells. These affordable PV systems cost nearly half of commonly used PV power systems in Japan. Greentec hope the system be used for industrial purposes rather than for residential use.
