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:PV solar products market sales
- According to the State Administration of taxation policy released last year, from October 1, 2013 to December 2015 3l, according to the 3% levy rate calculation. In Takamatsu as an example, if a month sales of 30 thousand, that he should pay the tax is 30 thousand x 3% x 50%=450 yuan.Residents issued 1 kwh of electricity, the state subsidy of 0.42 yuan; the national standard for the purchase of electricity from the desulfurization of residents with endless self generating electricity, the price is $0.42 per degree. To install and use a set of distributed photovoltaic power generation system with an average of 1 kilowatts of installed cost about 10 thousand yuan, if the 8 kilowatt system daily generating capacity of 30 degrees, 5 degrees every household consumption (no more than a price of 0.52 yuan), about 8 years to recover the investment
- Q:How to promote the use of solar energy in China
- Can you be more specific? Because I'm working on a project report, it's best to talk about two aspects of government and solar energy companies
- Q:Solar electric vehicle charging device
- Electric vehicle solar energy products are small in size, light in weight, easy to install and carry. Is a domestic initiative, has applied for national patent. Market potential is very large, very broad prospects.
- Q:Household solar energy productsThe product can be used at home, do not mention the solar energy, answer the water heater
- Solar thermal products are solar water heaters, as well as solar heating systems (usually in the North). Solar water heaters are used in several sets of hot plate, the more common is flat solar and vacuum tube solar two, the former used more in the south, the latter used more in the north.
- Q:The advantages and disadvantages of solar energy?Want to buy solar energy solar energy what is bad? Know about
- 2, slow heating, temperature can not be stored, no storage function,Because now the market does not rely on solar energy storage battery, so no matter how good the sun, onlyTo provide the energy required for the day, the next day must be used on the rainy day electricity heatingWater heater fee
- Q:What are the functions of the new vehicle negative ion solar charging humidifier?
- Brown vehicle negative ion solar charging humidifier, in addition to negative ions and solar charging function, but also can be used as car fragrance, you can add essential oils.
- Q:Is it hot in summer and the water is hot in winter?
- Wall type solar water heater can belong to the separated type solar hot water system, water tank placed in the balcony or exterior wall, the collector is placed at the south facade of building a balcony wall hanging type solar water heater with flat collector to absorb solar radiation into heat, heat to reach the water tank and the water heat exchanger, so that the temperature of the whole the water tank is increased gradually, let the user can enjoy free hot water from the sun.The successful use of plate heat exchanger technology in wall mounted solar products, not only improves the thermal efficiency of balcony wall products, and the successful implementation of the building safety products and life integration, so that the water heater installation expanded to all floors and is not limited to the roof, and greatly lifted the traditional solar water heater, frozen fried tube, easy Water Leakage, easy scaling problems.
- Q:What are the references of the solar automatic tracking system
