IIT Delhi Researchers develop high efficiency, shadowless and auto-rotating portable solar PVtower

A high-efficiency, shadow-free, auto-rotating solar PV tower has been built by scientists at the Indian Institute of Technology in Delhi, India. This tower can generate electricity from solar panels in a given area all day long. Low-cost electro-mechanical systems can be used to rotate the solar tower horizontally. The solar PV tower with reflectors has one. The mirrors/reflectors used in this solution help solar panels get more sunlight all day long, from 8 am to 5 pm.

Key Highlight:

  • IIT-Delhi researchers have created a high efficiency, shadowless (top panels do not shadow bottom solar panels) and autorotating Solar PV tower for photovoltaic power generation throughout the day.
  • No mechanical or mechanical tracking solar PV towers with high energy density (kWh/m2) are viable for all Indian seasons.
  • The mirrors/reflectors used in this approach increase solar panel irradiance from 8 a.m. to 5 p.m. From 9 a.m. to 4 p.m., the solar panels generate 1000 W/m2. The increase in sun irradiation from 9 a.m. to 4 p.m. increases power generation by 20-25 percent compared to conventional solar panel mounting.
  • A low-cost programmable electro-mechanical mechanism rotates the solar tower horizontally.
  • The IIT Delhi tracking system requires no LDR sensors, simply single-axis tracking, and draws very little electricity from the same solar tower.

High-efficiency solar panels at the bottom don’t get blocked by the panels at the top. The tower rotates itself to produce power all day long in a given area, even when the sun doesn’t shine.

The new ‘non-mechanical’ and mechanical tracking solar PV towers with reflection concentration can be used in all Indian seasons because they have a high energy density (kWh/m2). This means that they can be used in all Indian seasons. Furthermore, the mechanical tracking solar PV tower can be taken anywhere and used to make electricity. It can be mounted on a truck, made functional, and used to make electricity.

The space-saving ‘non-mechanical’ and mechanical tracking solar PV towers of 3kW and 5kW capacity, made by a team led by Physicist Prof. Dalip Singh Mehta, can be scaled up to more power with the concept of a solar tower array (green energy field).

These solar PV towers can be used for electric car charging stations, rooftop high-efficiency solar power generation for homes, schools, hospitals, shops, telecom towers, and more. Solar towers that can be mounted on the back of a car or truck can be used for agriculture (Agri-photovoltaics) like solar water pumps, solar battery charging for tractors, and more.

Both systems were patented by IIT Delhi and licensed to EP Sunsol Private Limited, which is based in Banglore and Mumbai. They can be used in commercial settings. EP Sunsol has already put the new systems in Chennai, Delhi, and Navi Mumbai. They have 3kW, 4kW, and 5kW systems, respectively.

After much research, we came up with a new way to mount solar PV towers and mirrors that follow the Sun’s movement. This new design is both light and cost-effective. According to Prof. Dalip Singh Mehta, the Physics Department, both non-mechanical and mechanical solar towers can produce 20% to 25% more power than traditional solutions while only taking up 50% to 60% of the roof space.

A solar tower that doesn’t move: Sunlight shines on solar panels and high-reflectivity mirrors that are vertically positioned in a way that allows them to be in the line of sight of it during the morning, midday, and evening hours. This leads to high-efficiency power generation from the Sun. People who use this method can make more power during non-peak Sun hours like 9 am to 11 am and 2 pm to 5 pm, and peak Sun hours from 11 pm to 2 pm, because the method allows them to be mounted in this way.

The mirrors/reflectors used in this solution help solar panels get more sunlight all day long, from 8 am to 5 pm. The solar irradiance on the solar panels has risen more than 50% so the power output will stay at 1000 W/m2 from 9 am to 4 pm. When solar panels are mounted in this way, they get a lot more sunlight between 9 am and 4 pm, giving them more power.

It has a low-cost electro-mechanical system that can be set up to rotate the solar tower horizontally. The mechanical tracking solar tower has reflectors on it. This way, the whole system with the panels and reflectors moves in the direction the Sun goes. A day starts facing east and ends facing west. The panels will be facing the East again to start a new day by the next morning. The new tracking system made by IIT Delhi doesn’t need any LDR sensors, needs only one-axis tracking, and draws very little power from the same solar tower.

Prof. Dalip Singh Mehta, Dr. Mayank Gupta, Mr. Virendra Kumar, Mr. Masood Ali, and Mr. Sanjay Ambwani were all part of the research team from IIT Delhi. The people who did the installation were Mahadevan R and Dr. Hitesh Mehta.
