A will appear solar energy panel with which to produce electricity ‘at night. This allows you to earn money and stimulate your own consumption. The arrival of the photovoltaic balloon marked a before and after in the sector, the same that will happen with this revolutionary invention. When the sun’s radiation stops with the break of night, solar panels usually become useless for hours. This was the main limitation.
However, a solar energy panel is able to generate electricity At night it breaks with what we knew so far about solar energy. Fossil fuels have long been used as a natural energy source, something that is starting to change. Oil, coal and gas reserves are being depleted and are also causing real damage in terms of pollution.
Under these circumstances, researchers around the world are exploring new sustainable alternatives to help reduce or even stop the damage caused by fossil fuels. That is why today we are witnessing the solar energy panel that fulfills its function even at night.
Electricity at night: this solar panel achieves the impossible
A team of engineers from the Stanford Universitydirected by Sid Assawaworrarit, Zunaid Omar j Shanhui fan, worked on this revolutionary invention. This ability to generate electricity at night is due to the panels’ ability to remain productive during the long nighttime hours.
According to studies, the Tierra It continuously receives a huge amount of energy from the sun, approximately 173,000 terawatts. Clouds, particles in the atmosphere and reflective surfaces such as snow mountains immediately reflect 30% of that energy back into space. The rest heats the land, oceans, clouds, atmosphere and the rest of the Earth.
However, this energy does not remain there. The Earth emits as much energy as it receives. For this reason, the planet gives off an immeasurable amount of energy in the form of infrared radiation. The only exception is the extra heat that greenhouse gases trap when humanity begins to burn large amounts of fossil fuels since the Industrial Revolution.
The infrared radiation emitted from the Tierra Warmth (or anything else) has wavelengths too long to be perceived by the human eye, but it carries energy. More than half of the solar energy that goes to the Tierra It passes through this system and then returns to space. What they’ve done at the university is develop a way to capture that energy as it leaves the planet.
Solar panel that produces electricity at night: its performance exceeds normal panels
The group of researchers is not the first to use a thermoelectric generator to capture this type of energy, as scientists at UCLA already made one of the first major innovations in this sector in 2019.
Integrating this new technology with solar panels that produce electricity During the day, the researchers have taken a step forward by allowing users to capture this energy. The proposed device integrates a thermoelectric generator that can take advantage of the temperature difference between the ambient air and the solar cell of the photovoltaic panel to produce electricity.
During the night, the solar cells radiate heat that rises into the atmosphere, ultimately causing the temperature to be slightly lower than the ambient temperature. The thermoelectric module generates voltage and electric current from the temperature gradient, a fact that can occur due to the thermal design of the system (which includes a client side and a cold side).
The amount of electricity produced at night is lower than what can be generated when there is light. However, it at least provides enough energy to illuminate a home. A milestone in the history of solar energy panelwho recently surprised us with the highway where you drive on solar panels.
