1. About solar power
Solar energy is the energy of the stream of electromagnetic radiation emitted from the sun, plus a small amount of the particle atoms absorbed and generated electricity by the Cell panels. Solar energy provides an infinite source of energy, produces no carbon dioxide (CO2) emissions and is particularly cost-free to use.

With the equatorial position, Vietnam has great daylight and radiation time. The Central regions from Da Nang to the South and the South have the highest number of hours of sun exposure in the year in the world, over 2000 - 2800 hours. The North Central region and the North have lower radiation levels (1500 - 1700 hours). However, the common ground is still much higher than that of European countries. With the calculation according to the above sun exposure time, for every 100m2 area, we have wasted 74,000,000 VND / year.
