A:We have ISO9001：2015，CE、RoHS certifications for all of our products.

Q:DO YOU HAVE MOQ FOR PLACE ORDER？

A:Low MOQ，1pe for sample checking is available

Q: What is the difference between photovoltaic products and solar energy?: At the same time, the solar photovoltaic power generation system, which is centralized, such as large northwest ground photovoltaic power system; one is distributed (divided by >6MW), such as building roof photovoltaic power generation system of industrial and commercial enterprises, residential roof photovoltaic power generation system.Solar photovoltaic effect, referred to as photovoltaic (PV), also known as the photovoltaic effect (Photovoltaic), refers to the uneven illumination of semiconductor or semiconductor and metal parts of the potential difference between the phenomenon of.Photovoltaic is defined as the direct conversion of ray energy. In the practical application, it usually refers to the conversion of solar energy to electric energy. Its implementation is mainly through the use of silicon and other semiconductor materials made of solar panels, the use of light to generate direct current, such as our daily lives can be seen everywhere in the solar cell.

Q: How to choose a good use of solar energy: See building structureMulti story building: installation is not limited, vacuum tube solar energy and flat panel solar energy products can be selected. Senior and small high-level: balcony solar energy products can choose. Villa Construction: can choose to install flexible, can be integrated with the construction of flat panel solar energy, flat panel solar energy is not affected by high-rise and special buildings, beautiful and generous.See pipeBecause the water heater is often placed on the roof, there is a certain pressure and the house in the summer, hot water with high temperature (about 90 DEG C), the actual situation of low ambient temperature, so the best selection of crosslinking tube or plastic composite pipe or reinforced plastic hose. The utility model has the advantages of high pressure resistance, high temperature resistance, low temperature resistance, no toxicity, no odor, small heat capacity, small heat loss, and easy to freeze in winter.After-sale serviceThe best choice of well-known brands and the strength of dealers (longer distribution time, product quality complaints rate) of the water heater. Because the solar water heater is durable consumer goods, and usually installed in the roof, once the fault, it is difficult to deal with their own. So the customer service service must be guaranteed, at present, the whole market free warranty period of 3 - 5 years.

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: What are the forms of solar energy? My villa would like to design a comprehensive utilization of solar energy.: Solar energy can solve hot water, power generation, heating, swimming pool, breeding, lighting, cooking, and many other problems, you really want to design a comprehensive utilization of solar energy can find me

Q: As a new energy solar energy has attracted more and more attention has been paid more and more practical application at home and abroad, I really want to know what are the solar energy application is very hope that we put forward their own views and even science fiction book that I want to do research on solar solar energy market in the military and political life etc.: 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..

Q: Solar energy application technology, there is no prospect: However, from a policy point of view, there is no industry like solar energy so much attention by the country. Compared with the traditional fossil energy, solar energy has obvious advantages. Therefore, the prospects are good.In a word, the future is bright, the road is tortuous!!

Q: Solar energy product development prospects?: 3 local regulations activate the project market, the development of the industry ushered in new growth, the rapid development of solar water heating system engineering market, government policy support. Engineering market is mainly concentrated in the town, the construction of new rural residents in the housing construction, but also for the development of the engineering market provides a new opportunity. To November 2010, some enterprises in the hot water system engineering sales have accounted for the overall sales of 40%, compared with the previous total of only 5% to 15% of the proportion, this growth can be described by leaps and bounds. In the completion of the sale after the maximum sinking, hot water engineering market city building will become the brand of a hotly contested spot, always adhere to the rural areas as the focus of the strategy in the next few years, may turn to the rural market both strategic transformation development market as the leading city.

Q: Advantages and functions of solar energy: The technical field of solar energy utilization: only use solar energy there are three major technology areas, namely solar thermal conversion, conversion and optical shop in addition, photochemical conversion, and energy storage technology. The solar photoelectric conversion, mainly various types of solar panels and solar cell power supply system is to convert sunlight directly into electricity a device can the photoelectric efficiency of the solar cell is about 10-14% and its products are the main types of monocrystalline silicon, polycrystalline silicon and amorphous silicon. The domestic product (of a photoelectric device full cost) the price is about 60-80% yuan / Watt Peak. The scope of application of solar cell is very wide. Such as satellites, unmanned weather station, communication station, television relay station the sun, clock, electric poles, black lights, navigation lights, railway signal lights. Solar thermal conversion technology. Most of the products such as water heaters, boiling water heaters, dryers, refrigeration and heating, greenhouse and solar house, Solar range and high temperature furnace, seawater desalination device, water pump, thermal power generation device and solar energy medical appliance

Q: Buy solar water heater mainly look at what?: Buy solar water heater mainly look at what?CDR | outside browse 976Recommended 2016-07-10 11:21:15 best answerBuy solar water heater, the four attention"First, the three components is the key to buy solar water heaters, analysis of production strength is very important. The strength of the enterprise is reflected in many places, and the key components are the most important. Three components include: vacuum tube, insulation layer and liner. The vacuum tube and the insulation layer determine the temperature rise and thermal insulation of the water heater, and the inner liner determines the life of the water heater, so these three parts are the core of the solar water heater. First, in accordance with national standards, the vacuum tube must be relatively high cost of high borosilicate 3.3 glass material, so as to ensure its light transmission and compression, anti-corrosion, impact resistance.
