Solar energy is not only a primary energy, but also renewable energy. It is rich in resources, can be used free of charge, and no transport, no pollution to the environment. Create a new form of life for mankind, so that society and human beings into an era of energy conservation and pollution reduction.The idea of building a space solar power station was first proposed in 1968, but it was not until recently that people began to really put it into action. Japan is one of the pioneers of the project, the project is expected to cost $21 billion, generating capacity of one billion watts, for the use of 294 thousand families. Solar power stations built in space, no matter what the weather, can use solar power, which is different from the establishment of solar power stations on the earth.
Although the solar resource amount equivalent to the use of human energy and more than ten thousand times, but the solar energy density is low, and it varies from place to place, from time to time change, this is the main problem facing the development and utilization of solar energy. These characteristics of solar energy will make it clear the role of solar energy engineering drawings in the overall energy system is subject to certain restrictions
The application of solar energy which is not very popular, the use of solar power also has high cost, low conversion efficiency of solar cell, but has been used in providing energy for artificial satellites. Humans rely on these energies to sustain their existence, including all other forms of renewable energy (other than geothermal resources)
The use of solar energy is very large, can be used to generate electricity, boil water!
