Someone said: make energy a solar system is greater than the energy it gained in the use (or, in life, rather than buy it buy more expensive electricity: This former is true, but However with current technology ratio is 1: 4 for the proceeds. That is, give 1 million to buy the system will gain 4 million in energy is obtained)
The fact that the use of solar energy in our country is still too far away from our dependence on hydroelectric power sources (as well as a clean energy) but actual demand for electricity and the miserable state of the reservoir below the dead were aligned a slight bell to the thoughts of the whole people!
