Recently a solar power tree was indigenously developed by scientists at Central Mechanical Engineering Research Institute (CMERI), one of the constituent laboratories of CSIR, Durgapur in West Bengal. It holds up to 30 solar power panels. The highlight of this innovation is to save land to harness solar power. It requires only 4 square feet of area to generate 5 KW electricity, which otherwise requires 400 square feet land, and harnesses 10-15% more power than in conventional way. It has water sprinkler at the top for self-cleaning of panels which enhances the efficiency of solar panels. Scientists are trying to make it rotatable to harness 10-15% more solar power than in static position. Hope, it may be well exploited in both urban and rural areas in energy crunched country like ours, at least for lighting purpose, if not for other uses.
