A singular pilot examine on ‘Agri Photovoltaic System,’ which is simultaneous use of land for photo voltaic power technology 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 difficulty in view of rising urbanisation and building exercise, and the ‘Agri Photovoltaic System’ would guarantee each solar energy technology and in addition cultivation of crops, mentioned Dr Avil Kumar Kodari, Director of Water Technology Centre at PJTSAU.

Agricultural land could be misplaced with the set up of typical photo voltaic power crops which shade the bottom making cultivation of crops troublesome. Coupled with this, the ever-increasing building exercise is leading to decreased availability of land, he famous.

The answer lies within the ‘Agri Photovoltaic System’ through which crops will be cultivated beneath the photo voltaic panels.

The system would yield two advantages — solar energy technology 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 as a consequence of frequent droughts and the photo voltaic power technology could be an assured earnings to the farmers with the enlargement of ‘agri photovoltaic system’ (below such drought circumstances).

Observing that there may very well be a discount in electrical energy technology from the photo voltaic panel if its temperature will increase, he mentioned cultivation of crops beneath the photo voltaic panel can have a cooling impact on the panel as a consequence of evapotranspiration (water misplaced from soil and crops).

Due to evaporation and transpiration, the photo voltaic panels will get a cooling impact thereby enhancing the effectivity of photo voltaic panels, Kumar informed PTI.

In some circumstances, crop yield will increase because of the shade of the photo voltaic panels, mitigating a few of the stress on crops attributable to excessive temperatures and ultraviolet rays (UV) injury.

Water requirement could be much less within the photovoltaic system as evapotranspiration will likely be decreased because of the shade to the crops.

He additionally mentioned “shade tolerant” crops (requiring much less mild) must be grown beneath the panels.

Vegetable crops require much less mild in comparison with crops like maize, rice, cotton which want extra mild 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 know-how reaches the farmers.

It started a few days in the past on the college.
