Following a rotating solar tree, the Central Mechanical Engineering Research Institute under the Council of Scientific and Industrial Research (CSIR-CMERI) has developed solar artifacts that can be installed at various public places to provide electrical power. Compared to solar power trees, however, these are more aesthetically designed for beautification of the place where these will be installed.
Design of two solar artifacts—Attapatram (Umbrella) and Surya Banaspati—has been completed and manufacturing of the prototypes will start soon. The technology is ready for licensing.
The umbrella, with a capacity of 1 KWp, can support a 0.5 KW load for 3 hours. It measures around 5×2.5 m2 and can be installed at the beaches, in parks and even in the lawns of bungalows.
The 5 KWp Surya Banaspati and 3 KWp Solar Flora can support 1 KW load for 10 hours and 5 hours (or other suitable combinations depending on the battery bank capacity), respectively. These can be installed on the road sides, in parks and in other remote areas to provide electricity.
Surya Banaspati has dimensions of around 8×5 m2, while Solar Flora is built with 4 sq.ft foundation and 490 sq.ft fan-out area.
Earlier, CSIR-CMERI developed a rotating solar power tree that auto-tracks the sun while occupying minimal land space. The tree rotates on its axis with all the solar panels together, generating 10-15% extra power from the sun. Rotation is given to the solar panels by rotating the trunk of the tree from its root and also by manually.
The solar tree costs around Rs 3 lakh for 3 kW capacity.
