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: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 energy product development prospects?

3 local regulations activate the project market, the development of the industry ushered in new growth, the rapid development of solar water heating system engineering market, government policy support. Engineering market is mainly concentrated in the town, the construction of new rural residents in the housing construction, but also for the development of the engineering market provides a new opportunity. To November 2010, some enterprises in the hot water system engineering sales have accounted for the overall sales of 40%, compared with the previous total of only 5% to 15% of the proportion, this growth can be described by leaps and bounds. In the completion of the sale after the maximum sinking, hot water engineering market city building will become the brand of a hotly contested spot, always adhere to the rural areas as the focus of the strategy in the next few years, may turn to the rural market both strategic transformation development market as the leading city.

Q:Product category and comparison of solar thermal utilization

The solar industry did a survey on the overall evaluation of the use of solar energy users, think very satisfied with only 3.5% basic satisfaction was 12.6%, average and unsatisfactory accounted for 35.2% and 48.7%; the user evaluation of the service, satisfied and satisfied for a total of 24%, and that no service dissatisfaction accounted for 76%.

Q:Solar panels with single crystal silicon or good thanks

Strongly recommended products tested in the sun or cloudy days will not be worse than the single crystalPolycrystalline solar panels solar panels with batteries, our company is committed to the development of solar cell production, processing and sales as one of the most professional. Product solar panels: respectively, including epoxy encapsulated battery board (PET process components) monocrystalline silicon, polycrystalline silicon, as well as laminated toughened glass packaging large components and amorphous silicon solar panels

Q:Buy solar water heater mainly look at what?

Two, after-sales service is very important in accordance with the three products, the principle of service of seven points. After sales service in the choice of solar water heater also plays a big role. With the development of solar energy industry, more and more manufacturers, in these new manufacturers, many do not have plant equipment, parts to take OEM processing, business variables, quality is difficult to guarantee. Due to the small sales, when operating for a period of time after a loss and product quality problems, will run away. The products are sold without service. So in the choice of solar water heaters, the choice of large brand products is essential.

Q:Advantages and functions of solar energy

The advantages of solar energy: solar energy as a new energy, compared with conventional energy it has three major characteristics: first, it is the most abundant energy source. It is estimated that in the past 1 billion 100 million years, the sun itself consumes energy in the future 2%. is sufficient to supply earth, using billions of years it is inexhaustible, inexhaustible.

Q:Good solar polymer or monocrystalline

1, the actual total power (load) and the use of time, should be reserved for the normal operation of the system;2, the local effective sunshine time, the proportion of rainy weather;3, the local meteorological data, such as sunshine time, weather disasters, storms and so on;4, the construction site must be open, in the installation of solar cells can not be tall buildings or other things blocking the sun;

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: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
