I think the quality of Changhong's solar power is better.
The quality of Changhong products can be assured, and the military industry enterprises are guaranteed. Most of my appliances are Changhongs. There are many varieties and different prices. You can go to the store and pick it up yourself. The quality of Taibiao Solar Energy is also quite good. It has imported foam machine and green technology of 360° constant temperature three-dimensional polyurethane foam. It has been strictly tested by the national laboratory and has good thermal insulation and energy saving effects. p>
Advantages and disadvantages of solar energy applications: 1. Advantages: (1) Universal: The sun shines on the earth, and there is no geographical restriction, no matter land or sea, never mind. mountains or islands. He cancan be directly developed and used without the need for mining and transportation. (2) Harmless: The development and use of solar energy will not pollute the environment. It is one of the cleanest sources of energy, which is extremely valuable today as environmental pollution becomes more and more serious. (3) Huge: The energy of solar radiation that reaches the Earth's surface each year is approximately equivalent to 130,000 billion tons of coal, and its total amount constitutes the largest energy that can be developed in the world today. (4) Long term: According to the current rate of nuclear energy generated by the sun, the storage of hydrogen is enough to last for tens of billions of years, and life on earth is also about billions of years. we can say that the energy of the sun is used in an inexhaustible way. 2. Disadvantages: (1) Dispersion: GoodAlthough the total amount of solar radiation reaching the Earth's surface is large, the energy flux density is very low. (2) Instability: due to the limitations of natural conditions such as day and night, season, geographic latitude and altitude, as well as the influence of random factors such as clear weather, cloudy weather, clouds and rain, solar irradiation reaches a certain level. Some soils are intermittent and extremely unstable, making large-scale application of solar energy more difficult. (3) Low efficiency and high cost: At the current level of development of solar energy use, some aspects are theoretically feasible and technically mature. However, some devices using solar energy have low efficiency and high cost. Generally speaking, the economy cannot compete with conventional energy sources. For a considerable period, thehe future development of the use of solar energy will be limited mainly by economic reasons.
