Solar energy is a renewable energy source. It refers to the heat radiation energy of the sun. The main manifestation is often referred to as the sun's rays. In modern times, it is commonly used to generate electricity or provide energy for water heaters. In the case of decreasing fossil fuels, solar energy has become an important part of human energy use and continues to develop. The use of solar energy has two ways photothermal conversion and photoelectric conversion, solar power generation is a new renewable energy. Solar energy in a broad sense also includes wind energy, chemical energy, and water energy on Earth.
Solar power
A photovoltaic panel module is a power generation device that generates direct current when exposed to sunlight. It consists of solid photovoltaic cells made almost entirely of semiconductor materials, such as silicon. Simple photovoltaic cells can provide energy for watches and computers, and more complex photovoltaic systems can provide lighting for houses as well as traffic lights and monitoring systems, which are integrated into the grid. Photovoltaic panel components can be made into different shapes, and the components can be connected to produce more electricity. PV panel components can be used on rooftops and building surfaces, and can even be used as part of Windows, skylights, or shelter installations, often referred to as build-mounted PV systems.
Photothermal
Modern solar thermal technology concentrates sunlight and uses its energy to produce hot water, steam, and electricity. In addition to appropriate technology to collect solar energy, buildings can also harness the sun's light and heat by incorporating suitable equipment in the design, such as giant south-facing Windows or building materials that absorb and slowly release the sun's heat.
