Photovoltaic power generation is by physical action, the solar energy directly into electrical energy directly to the process, does not produce any pollution and noise in the middle. Photovoltaic module is the core component of photovoltaic power generation systems, photovoltaic inverter is to produce direct current into alternating current (ac) devices, also is the important components of power systems.

According to whether the power grid, can be divided into two types of access, off-grid and interconnection. Off-grid belongs to the independent power supply system, from the power supply network; And photovoltaic power grid is the grid application way. Now, grid are the major ways of using photovoltaic (pv) power grid and can be divided into the ground power station and distributed.

Off-grid system consists of photovoltaic module, controller, inverter, battery and so on several parts. Have sunshine power generation, and the electricity is stored in the battery, the output electricity back on.

General large hydropower station on the ground, installed on the ground of large area, direct power grid; General installation and distributed power station in the family or the roof of the industrial and commercial buildings, is relatively small, hooked up to the grid at the same time, also for the building electricity. This two ways, the government subsidy standard is also different.


Q:Outdoor solar energy products, how can we do the process of IP65 level, the design of the water which should be noted that what? Beg enlighten heroes!
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
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: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
I have two sets of solar home, one is Huang Ming, a sijimuge, later a temperature than the Emperor Ming of the seems to be a little higher, are also good, but home Taiwan Himin's high, I want to buy one, want to try another brand is not the same effect
Q:What are the references of the solar automatic tracking system
Using solar automatic tracking in the photovoltaic power generation system, can effectively improve the utilization of solar energy. Therefore, the research in this paper to improve the efficiency of photovoltaic power generation, has important significance to promote the popularization and application of photovoltaic power generation. This paper proposes a photoelectric tracking mode and solar tracking combined all-weather solar the automatic tracking method. Analyzed and sunny, cloudy and rainy weather condition three
Q:In the domestic high temperature solar energy collector can achieve how many degrees, the existing product and the technology form?
The tower system, Zhongxingpengyue pattern, looks very spectacular, is the image project of solar thermal power generation love. Its size is limited to 10~20 megawatt level, the use of special, very limited usefulness. The tower system operating temperature 600~1000 degrees Celsius, there are several foreign demonstration projects, the home also has heard, but I do not know the specific progress to that stage, both at home and abroad have not heard of commercial operation successfully.Dish type system, the operating temperature of 700~1400 degrees Celsius, stand-alone dozens of kilowatts, the system 5~25 mw. Due to the small machine, a large number of prototypes developed at home and abroad, but also did not hear of a successful large-scale commercial operation example. Due to the use of Stryn hot gas engine, its manufacturing technology requirements are high, greatly limiting its development.
Q:Good solar polymer or monocrystalline
Many of my friends would ask is good or good crystal crystal, we many people buy just as ordinary lighting and small system to watch TV, to tell the truth this is really no need to care about the single crystal or polycrystalline, regardless of the need is a power is enough, two is the price is good!The difference between polycrystalline and single crystal: single crystal plate is black, polycrystalline plate is blue or color.Disadvantages: the same power of the single crystal plate with polycrystalline plate, polycrystalline board area slightly larger than the area of single crystal board, the same as the 50W polycrystalline will be 1.1 times larger than the single crystalThe utility model has the advantages that the polycrystalline plate is a plurality of directions to receive light and has good directivity. The actual test, hypothesis with one hand to block the sun's rays to solar power on the surface of a shadow, so many crystal board power current decrease is not obvious, but the single plate power current is reduced obviously, this is the advantage of multi crystal plate.
Q:Solar energy application technology, there is no prospect
You can check the latest trends on the internet. According to experts, the development of the dual opposition to China's photovoltaic industry has a short-term impact, but a national leader also said: I hope that businesses can survive six months... The following is a detailed process of the EU against china. In February 28, 2013 the European Commission announced that the EU PV Glass Association complaint based on originating in the photovoltaic glass Chinese anti-dumping investigation, the photovoltaic glass soda lime glass plate, with iron content of less than 300ppm, the solar transmittance in the above 88% characteristics.
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:The steps of making solar technology stubs
1 with a brush clean eraser material: big eraser, waste brush.Tools: scissors, glue.
