Solar Energy is one of the most renewable and easily accessible energy sources in the world. It is one of the most important non-conventional energy sources since it is abundant, free, and belongs to no one. People have been using solar solutions for industries for many years.

Generally, it's controlled in two ways:

Through the production of electricity:

Solar Photovoltaic (PV) devices or solar cells are used in this technology to convert the sun's energy into electricity. Photovoltaic gadgets use an electrical process that occurs naturally in certain material types known as semiconductors to generate power directly from sunshine.

Solar rays cause electrons in these materials to escape and flow through an electronic circuit, supplying power to the grid or directly powering electrical equipment. Solar watches, calculators, and traffic signals can all be powered by this type of energy. They're frequently employed in places that aren't connected to the power grid.

Solar collector devices:

A solar thermal collector absorbs the sun's rays and converts them into heat. This method uses solar energy to heat water similar to water heaters, hot tubs, and swimming pools. The more complicated collectors are used in concentrated solar power plants to generate energy by heating a liquid and turning a turbine attached to a generator. Simple collectors are commonly used for space heating in commercial and residential buildings.

Solar energy converted to electricity can be utilized to power lights or a variety of other devices right away. It's even better because it can be stored in batteries for later use. Normally, solar cells produce direct current (DC) electricity. It can, however, be converted to AC (alternating current) with the use of an inverter. Solar energy is converted to heat energy for heating of water and could be used immediately or can be stored as hot water in tanks for later use.

Solar energy can be classified as either active or passive depending on how it is captured and utilized. Inactive solar energy converts solar energy to heat energy, whereas mechanical equipment is not used in passive solar energy. Photovoltaic cells, solar thermal collectors, pumps, and fans are among the mechanical devices used to capture solar energy.

Without the use of active mechanical devices, passive solar technologies convert solar energy to thermal energy. It is mostly the process of capturing or deflecting the light for usage through the use of windows, walls, trees, building layout, and other simple procedures. Passive solar heating is a terrific method to save energy while also getting the most out of it. What happens to your car on a hot summer day is an example of passive solar heating.
