Since ancient times, people have been fascinated by the sun. Ancient civilizations expressed the sun as the supreme power, worshiping it as a God or Goddess. Farming and farming efforts depended on the sun's rays to grow crops and food. Recently, we have developed the ability to obtain energy from the sun called "solar energy". Photovoltaic (PV) system regenerates solar energy from sunlight into solar energy for electricity generation. The resulting technologies have promising implications for the future of renewable energy and sustainability. It is the cleanest and greenest renewable energy source. Say no to plagiarism.

A photovoltaic system includes photovoltaic panels, an inverter, a battery for storage, and interconnecting wiring. Photovoltaic panels absorb sunlight as an energy source to produce electricity. Photovoltaic (PV) panel is a packaged and connected assembly of photovoltaic solar cells. Most solar panels are currently made from crystalline silicon (c-Si) and multicrystalline and monocrystalline silicon solar cells. Photovoltaic cells convert sunlight (photons) into electricity using the photovoltaic effect. Solar energy is a renewable energy source because it can be used to generate electricity as long as the sun exists. Solar energy is an alternative to fossil fuels because it is a non-polluting, clean, reliable and renewable energy source. It does not pollute the air by releasing harmful gases like carbon dioxide, nitrogen oxide or sulfur oxide. Thus, the risk of damage to the environment is reduced. Solar panels are easy to install and require no wires, cords or power sources. solar panels create no noise and do not release any toxic substances. Solar energy is now used in photovoltaic power plants, rooftop solar PV systems, solar vehicles, solar panels on spacecraft and space stations. Solar energy provides only 1% of the world's total electricity production. . In 2010, the International Energy Agency predicted that global solar PV capacity could reach 3,000 GW, or 11% of projected global electricity generation by 2050, enough to produce 4,500 TWh of electricity . But the International Energy Agency predicted in 2014 that, under its "highly renewable" scenario, by 2050 solar photovoltaics and concentrated solar power would contribute about 16 and 11 percent, respectively. to global electricity consumption, and solar energy is said to be the largest source of energy in the world. of electricity. The United Nations Development Program, in its 2000 World Energy Assessment, found the annual potential for solar energy to be 1,575 to 49,837 EJ. Global photovoltaic growth averaged 40% per year from 2000 to 2013[33] and the total installed capacity reached 303 GW at the end of 2016. Bangladesh is among the countries in which the sun warms the surface throughout the year and therefore has strong potential. for the production of solar energy. Bangladesh has been short of energy for the past few decades, as its electricity generation relies mainly on imported fossil fuels and natural gas. Bangladesh has a strong potential to .
