Junction Box-qc 091721-B (5A)

Small box, big solution! Though seems simple, it actually devotes to the profound understanding of the PV. The back button hardwired terminal holds the cable tightly to the most, and as it hides in the potting adhesive, which effectively avoids the risk of leakage caused by traditional crimping; The optimal designed potting area minimizes the cost; Low external and extensible form design can meet the demand of most thin-film modules. Approved by TUV and UL, and universally accepted. QC Solar, innovation everywhere!

Q: In the domestic high temperature solar energy collector can achieve how many degrees, the existing product and the technology form?: Above three types of high temperature system, although the operating temperature difference is not small, but the overall efficiency is not much difference, both in the 20~25%, and the temperature is high, the comprehensive efficiency is high, the business efficiency is not high.Low temperature solar thermal system, refers to less than 200~300 degrees Celsius, power is almost blank, because the theory of efficiency of solar thermal power generation system at low temperature is relatively low, but personally think that if the utility system developed a reasonable, the comprehensive efficiency and business efficiency is not low.

Q: Is it hot in summer and the water is hot in winter?: Cloudy conditions, it is estimated that it will not be too hot, no care. If there is light in winter, then normal heating, you can use

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 third generation solar cells: Major technical breakthrough:Multi junction solar cellNanostructured solar cellsPhotoelectrochemical solar cell

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: New solar productsI would like to know the new type of solar energy production enterprises and the name, product performance and parameters.: Solar door lock lampThis is a new type of solar lock lamp solar panel for charging the battery, a LED lamp lighting, a full charge can continuously light 720 times, each time for 10 seconds, 10 seconds will be automatically extinguished, this time is enough for you to insert the key inserted the place.

Q: Solar panels with single crystal silicon or good thanks: 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: Monocrystalline silicon market when the turnaround, to what extent: The world climate change, because solar energy is a one-time investment, the current data show that solar power business life cycle for 25 years, before 3 - 5 years for solar power plant manufacturing cost, the carbon dioxide produced far less than the size of the fossil power plant, therefore, the climate change and carbon dioxide emissions contribute to global; 4, the application prospect of solar energy is very extensive, both the roof power station, large-scale solar power plants, or used in human life will be very popular, the power system involves the possible and the sun can be combined.

Q: The best authoritative research report, even if their YYThank you for the answer to the first floor, but I found the 2000 water heater Research Report, although a bit long, but you can also use: 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: Solar heating easy to use? Has anyone used it: Solar energy can be combined with heating. But it is still defined as "energy saving" more appropriate, rather than defined as "heating". The use of solar energy must be energy efficient. Suggest you can use gas stove heating, more money. If you want to save energy, then the gas stove and solar energy, solar bath, gas stove for heating and auxiliary heating as a solar energy.
