Solar energy - Electricity Generation: Solar radiation may be converted directly into solar power (electricity) by solar cells, or photovoltaic cells. In such cells, a small electric voltage is generated when light strikes the junction between a metal and a semiconductor (such as silicon) or the junction between two different semiconductors.
Once the solar energy is captured, the direct current (DC) generated by the photovoltaic cells flows into an inverter, which converts it into alternating current (AC). This AC electricity powers our devices and appliances . For any extra electricity not used immediately, there are three main options for homeowners:
Solar panels do not generate electricity, but rather they heat up water. They are often located on the roofs of buildings where they can receive heat energy from the Sun. Cold water is pumped up to the solar panel. Then it heats up and is transferred to a storage tank. A pump pushes cold water from the storage tank through pipes in the solar panel.
Solar energy can help to reduce the cost of electricity, contribute to a resilient electrical grid, create jobs and spur economic growth, generate back-up power for nighttime and outages when paired with storage, and operate at similar efficiency on both small and large scales. Solar energy systems come in all shapes and sizes.
Electricity is a convenient source of energy and can be generated in a number of different ways using either fossil fuels or renewable and sustainable technologies. Solar energy is used to generate electricity and to produce hot water. Solar energy is energy released by
A solar thermal system generates electricity indirectly by capturing the heat of the sun to produce steam, which runs a turbine that produces electricity. A solar photovoltaic system produces electricity directly from the sun’s light through a series of physical and chemical reactions known as the photovoltaic effect.
