A singular pilot examine on ‘Agri Photovoltaic System,’ which is simultaneous use of land for photo voltaic vitality era and agricultural crop manufacturing has been taken up on the Prof Jayashankar Telangana State Agricultural College (PJTSAU) right here.
Availability of land is changing into a problem in view of rising urbanisation and building exercise, and the ‘Agri Photovoltaic System’ would guarantee each solar energy era and in addition cultivation of crops, stated Dr Avil Kumar Kodari, Director of Water Know-how Centre at PJTSAU.
Agricultural land could be misplaced with the set up of typical photo voltaic vitality vegetation which shade the bottom making cultivation of crops troublesome. Coupled with this, the ever-increasing building exercise is leading to diminished availability of land, he famous.
The answer lies within the ‘Agri Photovoltaic System’ wherein crops will be cultivated beneath the photo voltaic panels.
The system would yield two advantages — solar energy era and in addition crop cultivation.
Crops like carrot, cabbage, cauliflower and broccoli have been chosen for the examine.
There’s a chance of crop failures in rain-fed cultivation resulting from frequent droughts and the photo voltaic vitality era could be an assured revenue to the farmers with the enlargement of ‘agri photovoltaic system’ (underneath such drought situations).
Observing that there could possibly be a discount in electrical energy era from the photo voltaic panel if its temperature will increase, he stated cultivation of crops beneath the photo voltaic panel can have a cooling impact on the panel resulting from evapotranspiration (water misplaced from soil and vegetation).
Due to evaporation and transpiration, the photo voltaic panels will get a cooling impact thereby bettering the effectivity of photo voltaic panels, Kumar informed PTI.
In some instances, crop yield will increase as a result of shade of the photo voltaic panels, mitigating a few of the stress on vegetation brought on by excessive temperatures and ultraviolet rays (UV) injury.
Water requirement could be much less within the photovoltaic system as evapotranspiration shall be diminished as a result of shade to the crops.
He additionally stated “shade tolerant” crops (requiring much less gentle) must be grown beneath the panels.
Vegetable crops require much less gentle in comparison with crops like maize, rice, cotton which want extra gentle to get the yield.
The pilot examine, undertaken in affiliation with a Bengaluru-based photo voltaic startup, would take a few years for completion earlier than the expertise reaches the farmers.
It started a few days in the past on the college.
