Solar Generation in Night hrs

How to get get Solar generations in Night 

      While standard solar panels cannot generate electricity at night,

    New technologies are being developed to address this limitation. 

    These advancements focus on harnessing the earth's heat or using infrared radiation emitted by the Earth to generate power, potentially creating 24-hour renewable energy sources. 

Key Concepts and Technologies:-

1) Anti-Solar Panels (Thermo-radiative Cells):-

How they work:-

   These panels, also known as thermoradiative cells, work in reverse of traditional solar panels. Instead of absorbing sunlight, they emit infrared radiation into space, which is then converted into electricity. 

  Nighttime energy:-

    They can generate electricity from the difference in temperature between the panel and the surrounding environment, essentially converting the heat escaping into space back into usable power. 

Potential:-

   It suggests they can produce a significant amount of power at night, potentially reaching up to 50 watts per square meter. 

 Research:-

   This technology is being developed at institutions like UC Davis, where researchers are working on improving their efficiency and practicality. 

2) Utilizing the Earth's Heat:-

a) Thermoelectric Generators:-

      A thermoelectric generator can be used to harness the temperature difference between a solar panel and the surrounding air at night.

b) Infrared Radiation:-

    At night, solar panels emit infrared radiation, and this heat can be captured and converted into electricity by a thermoelectric generator.

C) 24-hour power:-

This approach aims to provide a continuous renewable power source, both during the day and at night. 

3) Existing Solar Systems and Nighttime Power:-

   Off-grid Solar Systems:-

    Off-grid systems store excess energy generated during the day in batteries, which can then be used at night when solar panels are not generating power. 

Net Metering:-

   If you have a grid-tied solar system, you can use net metering to send excess energy back to the grid during the day. Then, when the sun is down, you can draw power from the grid, effectively using it as a storage system. 

Batteries:-

   Battery storage is essential for storing solar energy for nighttime use, especially for off-grid systems. 

4)Other Approaches:-

   Radiative Cooling:-

  Some research focuses on using radiative cooling to convert heat emitted by a solar panel into infrared light, which is then radiated into space, potentially generating power. 

Power from Rain:-

   Some researchers are exploring ways to generate electricity from rain, which can be used in conjunction with solar panels for a more consistent power supply. 

     In summary, while standard solar panels only work during the day, new technologies like anti-solar panels and thermoelectric generators offer promising solutions for generating electricity at night, paving the way for 24-hour renewable energy sources.
