The solar radiation energy on the Earth is very large, 40 minutes of solar radiation on earth, would be sufficient for the year of global human energy consumption. And solar power is absolutely clean, does not produce pollution. Therefore, solar energy is known as an ideal source of energy.
Access electricity from solar energy, it should through photoelectric conversion to be carried out the solar cells. The characteristics of solar power generators is that:
1. There is no depletion or danger of solar power generators;
2. Solar power generators are absolutely clean (pollution);
3. There is not limited geographical distribution of resources to solar power system;
4. You can use solar power generators at the nearest place;
5. Energy of solar power system is high quality;
6. You can access to solar power generators and spend a short time.
The downside of solar power generators is that:
1. The energy density of solar power system is small, that is, to occupy a huge area;
The energy obtained from solar power generators is connect with the four seasons, day and night, and confront other weather conditions.
Overall, however, as a new energy, solar energy has a great advantages.
