- 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: There are two years of foreign trade experience of the business to enter the basic salary and commission is what level is reasonable?Products are solar lights, solar chargers, solar power systems, solar power, LED induction lamps and other solar energy products
- Yes, for example, solar lights, developing and developed countries are in great demand
- Q: How to choose a good use of solar energy
- Water capacity of water heaterAccording to the number of people, to determine the size of the solar water heater capacity, three of the family at least choose the volume of more than 100L, in general, the larger the size of the solar water heater tank, the better.Domestic solar water heaters to buy the first to determine the volume of solar water heaters. The general situation of the shower, according to the volume of 40-50L/ people to determine the volume of products to be purchased; the general bath needs about 35kg - 50kg hot water (45 degrees Celsius). Because solar non conventional energy in rainy days can produce hot water heater, so choose twice daily water consumption, the sunny hot water thermal storage to be used in rainy days. In the case of two consecutive days, you can choose to use dual-use photoelectric, to ensure all-weather, all year round hot water use
- Q: What are the disadvantages of traditional solar water heater
- Because the water does not go glass tube, glass tube without fouling, the winter is not. The water heater can be pressurized, installed on the third floor, the first floor can also be used. If the water heater on the ground, the two floor, the third floor can also be used. So even if the existing architectural design is not perfect, the installation of solar energy, but also can be coordinated. At the same time, the electric water heater liner technology can also be used, so that the pressure bearing capacity of solar energy reached 6-10Kg.
- Q: Is it hot in summer and the water is hot in winter?
- Wall really electricity, as to what the effect depends on the brand. Hodge is certainly not good, the water temperature is low in winter. Now a lot of property to buy solar, generally for the hodge. As for the solar energy is better or you use absolute OK Himin - winter!!!
- Q: Solar energy products, that is, I would like to open a home solar products Daquan
- You come to buy a small brand, I guarantee the same brand and the water temperature. There ah, is to buy low in quality, the water temperature is much higher than the big brands, better quality, but the price is low. This is the answer to the water heater. Now I have to answer your question: I think a large and complete solar business success is unlikely, because you can do fine, because no sales manufacturers will hate you, you will not get a low price, so in the competition you will be in a passive position. There is a large investment in the business field, but this is taboo, because you invested huge output and small, out of proportion. As the election, do fine, do in this field, you are the boss. Others want to see your face. You can make a big profit this time.
- Q: Is there any water in the solar energy to water?
- How much is the automatic water supply set level up to the number 2 can not need to fill 100 set automatic water temperature time to remove any fill
- Q: Or must there be built - in battery? If yes, then use the mobile phone lithium battery can?
- . Cell phone lithium battery? Do you mean to put the mobile phone lithium battery on the solar panel? Do not Oh, can not be achieved, the direct use of solar panels charge mobile phone battery, then a little dangerous
- Q: How much does it cost to install solar energy in rural areas
- Four look at the brand, service. The solar water heater host outdoors year-round by professionals need to withstand exposed to wind and rain, maintenance, maintenance. At present, there are 4000 domestic solar water heater factory, as the country has not yet unified solar water heater testing standards, some of the quality of the product does not pass, installation services are not in place, to bring trouble to users. Buy solar energy is not only a product, but more importantly, service". Therefore, we should choose the strength of the brand name of professional manufacturers of products, such manufacturers to install service personnel are generally through professional and technical training, service and thoughtful, so that you do not worry, get the best protection.
- Q: Solar energy product development prospects?
- 2 domestic solar water heater market development problems, intense competition. 2010 in the first half, the solar water heater industry ushered in the most severe market test, the number of manufacturers dropped from last year's more than 5 thousand to the current more than 2 thousand and 800. There are relevant data show that nearly 80% of the solar water heater companies have varying degrees of decline in sales, inventory increases and other issues, solar water heater industry's profits are getting lower and lower. In nearly 6000 domestic solar water heater business, really have the scale of production and R & D capabilities of enterprises less than 20, the rest for some local small workshops and brand-name enterprises. However, the quality of product inspection management, backward production technology, low price dumping, Jerry phenomenon in these small enterprises, resulting in solar water heater market order and chaos, there are many hidden dangers.
