An IIT Delhi research team led by physicist Prof. Dalip Singh Mehta has developed a special high-efficiency and “shadowless” solar panel. Without shade, the panel can mainly be its part, as the lower solar panel is not. shaded by the top panels, making it more efficient. It is also auto-rotating PV towers for photovoltaic power generation in a specified area during the day.
“After intensive research, we managed to arrive at the lightweight and cost-effective new design for mounting solar PV towers along with mirrors with high reflectivity to track the sun’s movement. Both non-mechanical as mechanical solar towers are able to generate 20-25 percent and 25-30 percent more power respectively while using only 50-60 percent of the roof space compared to conventional solutions,” Prof Dalip Singh Mehta, Department of Physics , IIT Delhi said.

The developed ‘non-mechanical’ and ‘mechanical’ reflective concentration tracking solar PV towers are viable for all Indian seasons of the year with high energy density, the institute’s release claims. Another important feature is that the ‘mechanical’ tracking solar PV tower is portable, that is, the whole unit can be mounted on a truck, made functional and taken anywhere to generate power.
The space-saving ‘non-mechanical’ and ‘mechanical’ tracking solar PV towers with capacities of 3 kW and 5 kW are developed by the scientists of IIT Delhi. These are scalable to higher capacity with the concept of solar tower array (green energy field).
These solar panels are multifunctional, they can be used at charging stations for electric vehicles and for energy generation on the roof. It is also very efficient for the vehicle mounted solar tower with solar tracking for power generation which can be used for agricultural purpose (agri-photovoltaics), such as solar water pumping, tractor battery charging, etc .
Together with Prof Dalip Singh Mehta, Dr. Mayank Gupta, Virendra Kumar (Physics Department), Masood Ali (SeNSE) and Sanjay Ambwani (Design Department) are part of the IIT Delhi research team. The EP Sunsol Team, who did the installation, consisted of Mahadevan R and Dr. Hitesh Mehta.
