CAPACITY
• The Solar Tree, which is installed at CSIR-CMERI Residential 
Colony, Durgapur, can generate peak power of over 11.5 kilo watt 
(KWp).
• The installed capacity of the Solar Tree is above 11.5 kWp. It has the annual 
capacity to generate 12,000-14,000 units of Clean and Green Power.

DESIGN OF SOLAR TREE
• The Solar Tree has been designed in a manner to ensure 
maximum exposure of each solar photovoltaic (PV) panel to 
sunlight and also creation of the least amount of shadow area 
beneath. 
• There are a total of 35 solar PV panels in each tree with a 
capacity of 330 wp each.

ENERGY GENERATION
• The inclination of the arms holding the solar PV panels are flexible 
and can be adjusted as per requirement, this feature is not 
available in Roof-Mounted Solar facilities. 
• The energy generation data can be monitored either real-time or 
on daily basis.

FEATURES
• The Solar Trees were designed in a manner to ensure minimum 
Shadow Area, thus potentially making these Solar Trees available 
for widespread usage in Agricultural activities such as High 
Capacity Pumps, e-Tractors and e-Power Tillers.

COST
• Each Solar Tree will cost Rs 7.5 lakh and has the capability to 
incorporate IOT based features, i.e. round-the-clock CCTV 
surveillance in agricultural fields, real-time humidity, wind speed, 
rainfall prediction and soil analytics sensors.

POTENTIAL
• The Solar Tree has the potential to save 10-12 tons of CO2 
emissions being released into the atmosphere as greenhouse 
gases when compared with fossil fuel fired energy generation.
