Solar cell PK lithium-ion batteries, solar street light hanzhong city who can longer

And god said, let there be light, so the world will have the light. Sunshine is one of the things necessary for life growth factors, asing if is the inexhaustible, and solar power has become after the wind, water, the most favored by mass of quot; Future quot; Energy. The

and god said, there must be light, and then the world will have light. The sun is one of the essential factors of growth and life, everything seems to be it is inexhaustible. Therefore, solar energy has become the second most popular after the wind and hydro energy. The expression of energy in the future. Add the cause of the quot; The future express prefix, because solar power is still in the primary stage of development at present. Although there are many advantages in solar energy resources, but due to the energy conversion ability is weak, resource utilization is insufficient, the domestic solar energy industry has been in surplus. The development of solar energy can be traced back to the middle of the 19th century, when steam related inventions make people realize the heat energy and electric energy can be converted, and solar energy is the most direct source of generate heat. So far, solar panels are mainly for the civilian market, it can absorb sunlight through the photoelectric effect or photochemical effect of, directly or indirectly, the solar radiation energy into electrical energy. The difference between solar battery and lithium battery solar panels composed of multiple solar cells patchwork, as long as contact sun solar panels, can in an instant of output voltage and current loop conditions. If you don't consider technical factor, the solar cell is the only in the solar - today Electrical energy conversion in killing the best choice for all types of batteries. However, most solar cells used in large fixed places, such as transportation, communications and military fields, it seems to be little influence on the development of the consumer electronics industry. If one day the solar cell can be. Successful weight loss. When applied to the mobile electronic devices, is sure to change the overall direction of the technology industry. Today's most intelligent electronic products are rechargeable lithium batteries. Especially for mobile electronic devices, due to its light weight, easy to carry, application, functional diversity, the user is not restricted by environment situation in the process of using, and the operation time is long, the durability of lithium battery in spite of weakness, is still the most common choice. Although solar battery and lithium battery sounds like the same product, but they are not always the same. There are still the most essential difference between the two. In short, the solar cell is a kind of power generation equipment, not directly to store electrical energy, and lithium battery is a battery, can store electricity for the use of the user. Compared with the lithium battery, solar cells, one drawback is that they cannot be separated from the sun, the process of the solar energy into electrical energy and the sun's rays real-time synchronization. Therefore, for solar energy, only during the day or even a bolt is its home. With lithium batteries, however, if they are full of electricity, they can completely get rid of the limitation of time and environment, and can be used flexibly. The solar cell; Weight loss difficult because solar cell itself cannot store electricity, it is a very large for practical application of defects, so the researchers a brainwave, combine solar cells and large capacity storage battery. Lead battery is a kind of widely used in solar energy power supply system of large capacity storage battery. The combination of the two products make big volume of solar cells becomes more 'small'. Great, if you want to apply for a mobile device, you must first through the quot weight loss process. Because of the energy conversion rate is not high, the solar cell area of rizhao usually is very big, this is it ', '. On his way to lose weight the first major technical problems. At present, the solar energy conversion rate of cap is about 24%. Compared with expensive solar panels production, unless a large area is used, otherwise its usefulness will be greatly reduced, let alone a used for mobile devices.
