Solar energy is one of the major components of alternative energy and the renewable energy industry (RES). Today, it is customary to distinguish between three solar technologies: solar energy that can be used to generate electricity (photovoltaics, PV), to obtain the maximum thermal energy to generate the following solar energy (concentrated solar energy, CSP) or direct heat carrier heat, water frequency (solar heat). So let us explore how it works and go green with solar energy!
Solar energy use in photovoltaics is the most widespread. Photoelectric converter (FEP) in photovoltaics, solar energy is converted into electricity from solar cells, derived from solar cells, or photovoltaic converters (PV converters). It is customary to distinguish between several generations of PVCs, among which a large portion of the market is occupied by first-generation PVs based on silicon silicon obtained from monosilicon. The most promising and inexpensive third-generation solar cells are derived from living things. The technological power of photovoltaics development is associated with an increase in efficiency, which means more efficient conversion of sunlight into electricity in the solar cell.
In Concentrated Solar Power Systems (CSP), energy from the sun’s rays focuses on the system of lenses and mirrors in focused sunlight. This solar light is used as a source of heat to heat the active fluid, which is used for energy production, such as conventional CHP plants, or collected for energy saving. Another technology is to provide hot water only to CSP programs.
A simple example of using solar energy to heat water for domestic needs for special solar collectors. This method is widely used in southern countries such as Israel, Turkey, Greece, China, Croatia, where solar energy is most beneficial.
Solar energy and its use are hot spots for research and technological advancement. As with any renewable energy source, solar energy has its own characteristics. A major indicator of solar energy efficiency is an indication of disruption in the project region. Insolation shows surface exposure to sunlight and is measured in kWh / sq. M for a period of time (day, month, year). The stronger the region, the more energy from the sun can be converted into electricity or heat. However, solar power can grow in regions with low cooling from the sun, for example, in Germany, leading the world in the capacity of photovoltaic plants. Congestion is almost twice as low as in North Africa.
Solar energy, like other alternative sources of energy, can be harnessed and used in various fields of human activity:
- solar energy in the form of industrial heat and energy plants.
- solar power is the state of the terminals for the supply of thermal energy and electricity to commercial, industrial, administrative, social and other buildings.
- solar power in the form of the installation of private households.
- the use of flexible solar cells such as building materials (BIPV) and the textile industry (SFIT).
- solar power used to supply electricity to consumer goods such as calculators, laptops, batteries, etc.
- use of solar energy as a backup source of energy for vehicles.
- solar energy used to illuminate scoreboards, road signs, etc. at night;
- using solar energy in cooking.
