- Q: What are the disadvantages of traditional solar water heater
- As a developing product, solar water heater is not perfect. People are skeptical about solar water heaters, solar water heaters can normal water supply, can bring convenience to life?
- Q: Solar electric vehicle charging device
- Electric vehicle using solar silicon and polysilicon combination surface for Ling lighting plate, high quality and high efficiency crystalline silicon plate, the weak light response is very good, high photoelectric conversion efficiency, both indoor and outdoor sunlight, can be 24 hours of uninterrupted charging for electric vehicles to absorb light, can meet the different electric vehicles with electric load.
- Q: What is the future of solar power
- The roof of photovoltaic power generation is less than 2 million monthly sales tax, in accordance with the provisions of the national taxation policy, power users need to provide sales invoices to the power supply enterprise, the buyer also need invoice offset the cost, and the personal power does not have the qualification of business owners, led by invoices complicated procedures. More than 20 thousand of the tax can not get the invoice, it increases the difficulty of the sales of power generation households, is not conducive to promotion. The State Administration of Taxation issued, will reduce the tax burden on household electricity." According to the State Administration of taxation documents, since July 1, 2014, the national Power Grid Corp to buy power products distributed photovoltaic power generation project, by the national Power Grid Corp invoices, monthly household electricity generating sales of more than 20 thousand products, owned by the national grid enterprises in accordance with the taxable amount of the 50% generation of vat. The monthly sales of less than 20 thousand yuan may be exempt from vat. 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.
- Q: How to make better use of solar energy
- According to the history of the use of solar energy, solar energy has been used for more than 3000 years of history. The use of solar energy as a source of energy and power, only 300 years of history. The real solar energy as a much-needed supplementary energy in the near future, the basis of the future energy structure, it is a recent thing. Since 1970s, the rapid development of solar technology, solar energy utilization
- Q: Now there is no sun, cloudy days can use solar products?
- At present, I have not found this kind of solar energy
- Q: What are the functions of the new vehicle negative ion solar charging humidifier?
- Quite a lot of functions, when the car humidifier, anion purification car air, solar charging, you can also add the essential oils when the car fragrance.
- 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: Are solar panels now in use?
- Its function is similar to the frequency converter acting on the common AC motor, which belongs to the servo system.
- Q: Solar heating easy to use? Has anyone used it
- Advice do not believe! Solar heating is just a concept in china. In theory, in northern China, walls, windows and doors insulation to do a very good case, a square meter of solar collectors up to 3 square meters of heating area. If your house is 90 square meters, according to this calculation, you need to have 30 square meters of solar collector area
