Energy can be obtained directly from the sun. But that is in a slightly cloudy climate. Solar power is used all over the world. It is most commonly used to generate electricity, to heat water, and to remove salt from seawater.
Solar power can be generated in two main ways. Solar cells, convert sunlight directly into electricity. Most people know modern solar cells just by looking at them. As panels mounted on those houses. Today, solar cells are a rapidly advancing renewable energy technology. Many countries in the world have turned to the use of solar cells. In the future, it will be more attractive in the global power generation sector. Solar cells can also be used on a commercial scale or on a small scale for personal use. A small power system is a great solution to provide electricity to those who do not live around a power transmission line.
As the cost of manufacturing solar panels has dropped significantly over the past decades, it remains an affordable solution. The lifespan of solar panels is approximately 25 years and the lifespan can vary depending on the raw material used to manufacture them. Concentrated solar power is the concentration of solar energy using mirrors. These rays heat the fluid flowing through the heat exchanger, generate the vapor needed to operate the turbine, and activate the turbine to generate electricity. Concentrated solar power is also used to generate electricity for large-scale power plants. CSP A power plant usually reflects light from a mirror field to a tall tower. CSP The main advantage of a power plant compared to a PV solar power plant is that it is equipped with molten salts that can store heat.
One of the obvious features of solar cells is that they need sunlight to generate electricity. But now it is possible to generate energy using the same physics that was used to generate solar energy using sunlight, using a device that focuses on a space with a cold temperature. Solar cells are a potential way to generate electricity even at night, according to a report in applied physics articles published by the AIP in New York.
"The magnitude of the earth can be mentioned as a thermodynamic resource. "There is a symmetry between the energy of incoming radiation and the energy of outgoing radiation, according to optoelectronic physics" Shanhui Fan, who created the article, said. The new device looks like an anti-solar panel, instead of using radiation from the sun. However, as reported in articles on applied physics, the new system uses the opposite light (illumination) effect.
Masashi Ono (Masashi Ono), the lead author, explained that there is a huge temperature difference between the Earth and space. Even on Earth, the coldest place on our planet, the temperature difference is usually around 200C. The limitations of a new device are its technology, not environmental conditions. The current device generates only 64 nanowatts of small current per square meter. The power we can produce from this experiment is far less than the theoretical limit. The theoretical value is 4 watts per square meter, which is more than a million times more than the current production. Therefore, it is important to innovate to generate the energy needed at night and to improve it as soon as possible.
It is reported that the world famous Tesla (Tesla) company has worked to produce and sell new types of tiles required to build a solar roof that looks like a natural roof. The roof is made of glass tiles that can be powered by sunlight and is designed to look like the roof of traditional houses. Some of the tiles that are installed are made of solar cells that can generate electricity from sunlight, but all the tiles look the same.
Elon Musk, founder of Tesla, said his goal is to create a new solar roof that will last longer, look better and receive solar energy at a lower cost than existing roofs with solar panels. New solar panels are three times stronger than regular tiles, but weigh less than half that Tesla offers a lifetime warranty on solar panels. However, the company estimates that the cost of installing a solar roof over a 240 square meter home will be $ 69,000. It costs more than a roof made of materials, including traditional tiles. However, the company has stated that this additional cost can be covered when the solar roof reduces the payments that residents have to make for future electricity bills.
The government's tax-deductible policy on some solar-powered users also benefits. They also manufacture and market batteries for storing solar energy that provide electricity to homes. The battery, called Powerwall, which stores electricity so that it can be used at any time of the day or night, is released free of charge during the construction of the new solar roof. "We manufacture solar-powered electric cars, so both of these products help save the planet's energy supply. When thinking about a sustainable energy future, we need beautiful roofs that can be solar-powered as well as attract human attention. Vehicles will be charged and that is the future we look forward to. ” Musk said.
