Solar (Solar Energy), generally refers to the radiation energy of sunlight

Since the formation of the earth, organisms have mainly lived on the heat and light provided by the sun, and since ancient humans have also known to dry objects with sunlight as a method of preserving food, such as making salt and drying salted fish. However, under the reduction of fossil fuels, it is intended to further develop solar energy. The use of solar energy has passive use (photothermal conversion) and photoelectric conversion in two ways. Solar power is an emerging renewable energy source. In a broad sense, solar energy is the source of many energy on the earth, such as wind energy, chemical energy, water potential energy and so on. In billions of years, solar energy is an inexhaustible, inexhaustible source of energy.

Solar cells have been used to provide energy for artificial satellites.

Thus, it can be calculated that the energy obtained by the earth can reach 173,000TW. The standard peak intensity at sea level is 1kw/㎡, and the annual average radiation intensity at a 1.24 h on the earth's surface is 0.20kw/㎡, which is equivalent to 102,000TW of energy on which human beings depend for survival, including all other forms of renewable energy (except geothermal energy resources).

Solar energy utilization consists of solid photovoltaic cells made almost entirely of semiconductor materials (e. g., silicon).

Photovoltaic panel components can be made in different shapes, and the components can be connected to generate more electricity. In recent years, photovoltaic panels can be used on roofs and building surfaces, even as part of windows, skylights or shading devices. These photovoltaic facilities are usually called photovoltaic systems attached to buildings.

Advantages of Solar Energy

The sun shines on the earth, without geographical restrictions, whether land or sea, whether mountains or islands, are everywhere, can be directly developed and utilized, and without mining and transportation.

Its basic principle is to collect solar radiation energy

Through the interaction with the material into heat energy to be used. At present, the most used solar energy collection device, mainly flat plate collector, vacuum tube collector, ceramic solar collector and focusing collector, such as 4 kinds. Usually according to the temperature and use of different, and the solar thermal utilization is divided into low temperature utilization (<200 ℃), medium temperature utilization (200~800 ℃) and high temperature utilization (>800 ℃)
