‘Solar Power Tree’ has been indigenously developed by the CSIR-Central Mechanical Engineering Research Institute (CSIR-CMERI), a constituent laboratory of Council of Scientific and Industrial Research (CSIR).
Land is the major constrain in shifting to solar energy. As solar power tree is aimed at utilizing minimum space to harness maximum solar power, stand as boon to India’s solar power aspirations. It will also set India in it’s path to achieve it’s ambitious target of 100 GW by 2022.
* Solar power tree takes only 4 square feet of land for a 5 KW Solar Power tree, whereas in a conventional layout, it requires 400 square feet of land.
* By holding the photovoltaic panels at a higher height, on an average it gets more sunrays for one hour in a day. As a result, it is possible to harness 10-15% more power in comparison to a conventional layout on ground.
* It has a battery back-up of 2 hours on full load, hence giving light even after sunset.
* It is facilitated with water sprinkler at the top for self-cleaning of panels, that increases the efficiency of the solar panels.
* The estimated cost of the device is around Rs. 5 Lakh for a 5 KW specification.
* Even the cultivable land can be utilized for solar energy harnessing along with farming at the same time. This innovation finds its viability both in rural and urban areas.
Innovations that address local challenges will always lead to path of efficiency and sustainability. The invention of solar power tree inspired from alignment of leaves in plant to harness sunlight for photosynthesis is an example of such local innovation in India. With more emphasis on R and D in premier institutions like CSIR, India will soon be a leader in solar technology besides leading solar energy producer.
