Q:What are the current domestic solar energy products, which practical
Our use of solar energy can be roughly divided into two types of light and heat conversion and photoelectric conversion, in terms of household solar water heater and solar photovoltaic power generation.The solar water heater is widely used, manufacturers have Wuxi Suntech, linuoruite, Himin Solar energy, I think the emperor of the more, certainly not bad.
Q:Solar energy has some disadvantagesDetailed description of the problem, to help the respondents give accurate answers
Disadvantages of solar energy:The use of solar energy has its drawbacks:First, the current density is low, the sun is better, the ground floor area of 1 square meters of energy received only about 1 kilowatts. It is often necessary to set up a large number of lighting surface to meet the use requirements, so that the large area of equipment, materials, cost increases.Second, the greater the impact of the atmosphere, to bring a lot of difficulties.
Q: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 durability
Q:Solar industry products trade prospects
Base salary is not high, the Commission is generally 1-2%, different places.
Q:Advantages and functions of solar energy
Second: the earth, no matter where there is solar energy can be in situ development and utilization, there is no transport problem, especially for trafficunderdeveloped rural areas, islands and remote areas had more use value. Third: solar energy is a kind of clean energy. In the development and use, does not produce waste residue, waste water and gas, also there is no noise, but will not affect the ecological balance. Absolutely not cause pollution and pollution.
Q:Buy solar water heater mainly look at what?
Second, liner thickness. The quality of the liner determines the life of the water heater, if the water tank, the water heater will be scrapped. Major brand manufacturers use thickness of not less than 0.5mm of SUS304 food grade stainless steel liner. Argon arc welding is adopted to ensure the service life can reach more than 15 years. Other brands of water heaters in the liner between 0.2mm-0.4mm, the use of a period of time there will be water leakage problem. Therefore, consumers in the purchase of products must ask the thickness of the liner. At the same time, but also beware of patch water tank, the water tank liner is made up of a number of scrap steel belt, the entire inner bladder welding as many as dozens of times
Q:How to promote the use of solar energy in China
Overall, the use of solar energy is still very fast, or how the United States will be on China's solar energy products to ban it? As for the overall development of the domestic solar energy industry is good, but still need to do a lot of work. For example, how to improve the quality, efficiency, etc..
Q:Outdoor solar energy products how to process the level of IP65
Third, the less the number of parts as possibleFourth, when the whole is a way to allow glue
Q:How much does it cost to install solar energy in rural areas
The question is more ambiguous, the installation of solar energy in rural areas there are many kinds of circumstances, is not used all year round, is not the villa type, is not the need for surfing the bathtub?Install solar energy in rural areas, the number of homes decided to install what kind of solar energy.
Q:What about solar products?Solar panels solar panels
Solar photovoltaic products: photovoltaic modules and photovoltaic components, modules and components of rural production equipment, photovoltaic power generation system, photovoltaic equipment installation and accessories, grid connected photovoltaic system and photovoltaic transmission and distribution equipment; photovoltaic power / battery, charger, controller, inverter, water pump, solar power system equipment, solar energy conversion equipment, fuel cell, silicon solar cell, thin film solar cells, silicon single crystal silicon cell / raw materials, photovoltaic panels, glass cutting machine, testing equipment, various kinds of stove; wind solar diesel battery hybrid power systems, solar desalination system, solar photovoltaic electric vehicles, hydrogen production system, photovoltaic power generation system of computer application software; testing equipment of photovoltaic power generation system.
