Q: How to make solar energy?: Many products using solar energy.1 boxes, 1 plastic bottles and cans; paint, glue, aluminum foil, plastic cloth; out of the plastic foam, metal bottle and transparent plastic paper, ready to do a solar water heater. You can do it.

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: What are the third generation solar cells: What criteria are you referring to?There is not a recognized way of generational change;So there is no way to answer!

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: 1 natural circulation:This type of storage tank is placed above the collector. Water heating collector in solar radiation temperature rise, causing the collector and tank water temperature and have a different density difference, thus causing buoyancy, this is like a hot siphon, the water flow in the water storage tank and collector. Because of the density difference, the water flow rate is proportional to the solar energy absorbed by the collector. This kind of type is widely used because it does not need the circulating water and the maintenance is very simple.2 forced circulation:The water in the hot water system makes the water circulate between the collector and the water storage tank. When the water temperature at the top of the collector is higher than the water temperature of the bottom of the water storage tank, the control device can start the water to make the water flow. A check valve is arranged at the entrance of the water to prevent the nighttime water from being driven by the collector to cause heat loss. The flow rate of this type of hot water system can be known (as a result of the flow from the water), easy to predict performance, can also be calculated in a number of hours of heating water. As in the same design condition, the natural circulation has can gain higher water temperature strengths, but because it must use water, the water power and maintenance (such as Water Leakage etc.) and the control device of dynamic stop, damage easily water problems. Therefore, in addition to large hot water system or the need for a higher water temperature, the forced circulation, the general use of natural circulation water heater. Solar power system consists of solar cells, solar controller, battery (group). Such as output power for AC 220V or

Q: Home solar heating products can not mature?: Solar power generation, per square meter of power generation in 120W or so, the cost per square meter in 1500 yuan, the greater the area the lower the price2013 PV industry in Europe and the United States antitrust investigation, overcapacity led to the collapse of a large number of photovoltaic industry in Zhejiang, solar prices have fallen. This can be checked at any time onlineRecommended to buy solar water heater price per price in the 150-180 yuan, including in accordance with the material and other costs, buy a good look at whether there is a reliable after-sales

Q: What are the references of the solar automatic tracking system: Tracking models were taken; gives the specific design ideas and methods of photoelectric tracking mode; to analyze and determine the sun trajectory calculation method, verified the feasibility of this method. According to the proposed tracking method, design a set of automatic tracking type independent solar photovoltaic power generation system. The system is a small photovoltaic power generation system based on automatic solar tracking, all-weather, high efficiency run independently, as much as possible the conversion of solar energy into electricity, to provide electricity load. The whole system is divided into automatic tracking system and two subsystems of solar photovoltaic power system, the photovoltaic power system is in the forest fire specific applications are analyzed and designed respectively. The design of hardware and software of the two subsystems. The hardware design includes the position of the sun and light intensity detection, calculation The software part of the system is designed, which is composed of computer control, data acquisition, external clock and photovoltaic power supply

Q: The advantages and disadvantages of solar energy?Want to buy solar energy solar energy what is bad? Know about: I personally think that the use of solar energy is not very environmentally friendly, because the market is currently the main products of solar energy use monocrystalline silicon or polysilicon, thin film with very little. We all know that silicon is a heavy metal, pollute the environment and can not be removed, because the film component cheap but the conversion rate is low, can only be used in small products, such as computer, application of technology products such as lamps, although the silicon conversion rate is high but the price is expensive, so the application of products currently on the market to see the most use of polysilicon, 25 years after this type of product, service life expires, how to deal with??? Is a problem, so I still want to improve the conversion rate of thin film components.

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: The steps of making solar technology stubs: Step:1, the walnut tip toward the fire on the fire for a while, and then thrown into the cold water, walnut will split along the seam.2, the suture will break the walnut into two halves.
