Q: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.
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:What are the current domestic solar energy products, which practical
Photovoltaic power generation system is mainly composed of solar cells, batteries, controller and inverter, the main part of solar cells. In the application of more public amenities such as solar street, home of the little, of course you can install the system of solar photovoltaic panels at home, 1W about ten dollars, plus the controller, you can see if you are able to supply applications at home how much money.
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:Solar products must be in the sun
Other light sources can be used to meet the needs of the product (e.g., solar watches can be recharged by other light sources)
Q:How to open solar stores
The store is fixed, the operator store is active, to store as a sales point, to regional radiation operations, will revitalize the store". Travel to a new solar 5S shop transaction according to the author, the store address provided by the dealer, the way to find the past, turned half an hour did not find a living map, taxi drivers are also puzzled, and finally had to ask the clerk to shop the way to reach the destination. The new store is completely in line with the provisions of the company, but what you want to find the store, even the best, are castles in the air for consumers, the effect not large, dealers pay no return. The development of the store, the author thinks that in order to repair the expansion, double attack. Let people pay attention to the store to enliven sales, real effort outside the shop. Although the products set up shop, but out of the store to sell, will make the distribution as boundless as the sea and sky. Target customers want to buy your product, how to let them find your shop? How to let more people know that you are selling some kind of solar energy products? Make use of all available opportunities, resources, and ways to hit your local brand! Let you fill the local market.
Q:Solar industry products trade prospects
Yes, for example, solar lights, developing and developed countries are in great demand
Q:How to make solar energy?
Do experiment. We put the foil affixed to the box, to reflect sunlight. Then put the metal bottle full of water in the box and secure it with a plastic foam.
Q:What are the third generation solar cells
What criteria are you referring to?There is not a recognized way of generational change;So there is no way to answer!
Q:What are the uses of solar energy?
Solar cell[material requirements] ultraviolet radiation resistance, light transmittance does not fall. Tempered glass components can withstand the diameter of 25 mm of ice hockey at a speed of 23 m / sec.[properties of EVA film curing with the requirements after] the transmittance is more than 90%; the crosslinking degree is greater than 65-85%; peel strength (N/cm), glass / film is greater than 30; TPT/ film is more than 15; the temperature resistance, low temperature, high temperature of 85 DEG C to 40 DEG C; the back of the solar cell, aging resistance corrosion resistance, ultraviolet radiation, airtight etc..[use] solar power is widely used in solar lights, solar lamp, solar portable system, solar mobile power, solar products, communication power supply, solar lamps, solar buildings etc..
