What is the purpose of solar panels?

Answer 1

Solar energy is the radiant light and heat from the Sun that has been harnessed by humans since ancient times using a range of ever-evolving technologies. Solar radiation along with secondary solar resources such as wind and wave power, hydroelectricity and biomass account for most of the available renewable energy on Earth. Only a minuscule fraction of the available solar energy is used. Solar power technologies provide electrical generation by means of heat engines or photovoltaic. Once converted its uses are only limited by human ingenuity. A partial list of solar applications includes space heating and cooling through solar architecture, potable water via distillation and disinfection, day lighting, hot water, thermal energy for cooking, and high temperature process heat for industrial purposes. Solar technologies are broadly characterized as either passive solar or active solar depending on the way they capture, convert and distribute sunlight. Active solar techniques include the use of photovoltaic panels, solar thermal collectors, with electrical or mechanical equipment, to convert sunlight into useful outputs. Passive solar techniques include orienting a building to the Sun, selecting materials with favorable thermal mass or light dispersing properties, and designing spaces that naturally circulate air. The sun has produced energy for billions of years. Solar energy is the sun's rays (solar radiation) that reach the earth. Solar energy can be converted into other forms of energy, such as heat and electricity. In the 1830s, the British astronomer John Herschel used a solar thermal collector box to cook food during an expedition to Africa. Today, people use the sun's energy for lots of things such as heating houses, providing energy for cars, and, and having it as an extra energy source Heat water - for use in homes, buildings, or Swimming Pools. Heat spaces - inside greenhouses, homes, and other buildings. After the 1973 oil embargo, there was a resurgence of interest in solar energy. Faced with a possibility of scarce oil resources, the United States government allocated $400 million per year, from a mere $1 million per year, for solar energy research. The expenditure is small compared to the expenditure on nuclear research. Currently, there is a need for allocating increased resources in solar research. Compared to the old forms of depletable energy (coal, oil, nuclear), solar energy offers a clean renewable form of energy. This presentation will provide an overview of the past, present and future of solar energy. # The purpose of the solar panel is to capture energy from the sun and to turn this energy into electrical energy. The electric motor then uses this electrical energy to power the wheels of the solar car.

Answer 2

Solar panels are modules that are made up of solar cells. The solar cells provide a way to convert the sun's energy into electricity. In other words, solar cells assembled into solar panels allow us to generate solar power. This is good because getting electricity directly from sunlight is better for the environment. With solar panels, we can reduce the need for getting our energy from other, more environmentally harmful, polluting, and non-renewable sources.

Answer 3

The main purpose of solar panels is to convert sunlight into electricity. They are a renewable energy source that reduces dependence on fossil fuels and helps mitigate the impacts of climate change. Solar panels can be used for residential, commercial, and industrial applications.
