The PV-powered DC floating pump system-a new revolution

摘要

The PV powered DC floating pump offers new hope for at least twomillion small farmers in India for meeting their irrigation water needsfrom open wells. A six-year 200-PV-pump demonstration program in theSouthern States of India by the Polyene Group has established that theDC floating pump (600 to 860 Wp capacity), powered by amorphous siliconPV modules, is ideally suited for open well irrigation up to 5 acres ofland. Design changes and product improvements carried out to the PolyeneDC Floating pump system, over the last six years, on the basis of fieldperformance/feedback, have also been profiled in the paper
