5. FAQ

1. How to choose backsheet for solar panel?
It’s not easy question, but the first but most important thing is that the life period of the solar panel depends on the material quality of the backsheet.

2. If there is some scratches on the backsheet, how to deal with the solar panel?
Firstly, the scratch will destroy the waterproofness of the solar panel through the backsheet, which will finally have bad influence on the performance of the panel,; then the scratches on the backsheet should be regarded as defective and you should contact with the supplier or manufacturer to change it as soon as possible.

3. What is the color that backsheet should be?

Absolutely is white. As time goes by, the corrosion of the backsheet makes the white color into yellow. So make sure when you get the new solar panel the backsheet is in appropriate state.

Q:Solar derived products The role of solar panels is to convert solar energy into electrical energy, the output of DC stored in the battery
Through the analysis of the site we came to the conclusion that the whole system we use wireless bridge hybrid network Winncam wireless bridge 2.4 and 5.8, from point to point and point to multipoint network, set up three level wireless transmission network, which can smooth the audio and video in the network through the front-end equipment; we recommend using infrared network the camera, rear end accept can use a computer, but also can use the DVR DVR to use the decoding function. Finally, we can view and manage the entire system at the back end. The most extensive application of solar energy in the early stage is to heat water, and millions of solar water heaters are now available all over the world. The main components of the solar water heating system include three parts: the collector, the storage device and the circulating pipeline. In addition, there may be auxiliary energy device (such as electric heaters, etc.) used to supply without sunshine, in addition still may have forced circulation with water, with water level control device or control electric parts or temperature and received loads of pipeline etc.. According to the cycle of solar water heating system can be divided into two kinds:
Q:Solar energy items in daily life
Solar ice pad, solar panels, solar street lights, etc., are living in the solar green energy-saving products.
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:Consumer behavior analysis of solar water heater
Competitor analysisThe solar water heater industry faces competition and substitute competition, has formed a professional brand, regional brand, brand and brand-name appliances co-exist in the market, the industry has fish, uneven in quality situation. With the competition and homogenization aggravating industry "reshuffle" is inevitable in the competition, need to break through the differences, creating a unique selling point, can focus on the product itself, can also be separated from the product itself, to create new demand from the consumer point of the competition range, consumers in the purchase of solar water heater in the purchase of solar energy is not, but convenient, safe, saving, healthy use of hot water. If you can surround the tube"
Q:How much can the domestic high - temperature solar collector reach
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.
