Outdoor solar energy products how to process the level of IP65
- First, the packaging process,Design must consider the requirements of water, the structure can not be set up obstacless
How to promote the use of solar energy in China
- In this regard, the government should do a lot of work, industry associations have also made the relevant advances
The advantages and disadvantages of solar energy?Want to buy solar energy solar energy what is bad? Know about
- You mean the solar water heaterSimply say:Benefits: power saving, safety,Disadvantages: 1, temperature affected by the weather,Because solar water heaters rely mainly on the absorption of sunlight, the light energy into electricity for heating waterSo the intensity of the sun directly affects whether you need to use electricity heatings
How to make solar energy?
- Finally, cut a large hole in the box and put on a plastic wrap to absorb sunlight. A simple solar water heater is finished. I do the "solar water heater" to the teacher. The teacher said: "you have not put black metal bottles, so absorb sunlight more slowly, the water temperature is not easy to rise." So, we put the bottle of black metal.s
How much can the domestic high - temperature solar collector reach
- Solar thermal power can be divided into three categoriesTrough system, tower system and dish system, they all belong to medium and high temperature system,Trough system is relatively popular in the other two categories, but also the most promising class. Operating temperature of 400~700 degrees Celsius, the scale is not limited to a few dozen megawatts, up to the level of Gigabit, there are some examples of successful commercial operation abroad. There are many prototypes in China, but there is no practical system.s
Home solar heating products can not mature?
- Solar panel power generation, then the proposed size of the proposed group, mainly the power substation and storage of electrical equipment is very expensive, the highest conversion rate in the 17%-20% efficiency is very low, not as good as plant photosynthesisNow the national clean energy, photovoltaic power generation policy is more than 10kW can be free of charge, but the price of electricity recovery is very low, cumbersome procedures.Buy solar water heaters, the first proposal to consider the local climate, installation conditions, economic prices and durabilitys
Solar industry products trade prospects
- Base salary is not high, the Commission is generally 1-2%, different places.s
What are the uses of solar energy?
- Uses as follows:Photothermal utilizationIts basic principle is to collect the solar radiation energy, and convert it into heat energy. At present, the most widely used solar collector, there are 4 types of flat plate collector, vacuum tube collector, ceramic solar collector and focus collector (trough, dish and tower). Usually according to the temperature and the use of the different, and the use of solar thermal light is divided into low temperature (<200 DEG C), the use of medium temperature (200 ~ 800 C) and high temperature utilization (>800 C). At low temperature using mainly solar water heater, solar dryer, solar distiller, solar heating (solar room), solar greenhouse, solar air conditioning system, the temperature is mainly using solar cookers, solar thermal power generation heat collecting device, mainly using high temperature high temperature solar furnace etc..s
