Q:PV solar products market sales

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.

Q:What is the difference between the expensive solar energy and the cheap one?

Cohesive light film vacuum tube is used their thermal power generation technology, positive negative light, heat, warming faster, higher water temperature, which is unique in the world (Himin patent, ultra cold polar tube, Antarctic expedition team designated products, 40 degrees below zero still out of hot water, hot water is not broken; they are equipped with low winter) the temperature of the water level sensor, accurate induction, automatic operation of the whole system, you don't have to worry about is not water ah, can bathe ah; not only that, once the hot water machine what, their customer service staff will serve you within 48 hours. This is not high price but not expensive, is the value for money, or even value for money?

Q:What is the future of solar power

Those who despise misleading consumer advertising! Solar power generating capacity per square meter is about 120W, the cost per square meter 1500 yuan in the area, the greater the lower the price of 2013 the PV industry has been an antitrust investigation in Europe, because of overcapacity in Zhejiang's large solar photovoltaic industry collapse, the price fell down. This can always online inspection recommended the purchase price of solar water heaters each priced at 150-180 yuan according to material, and other costs, the purchase is optimistic about the local power and reliable customer service of solar panels, the size of the group suggested bidding, mainly electric power and storage equipment is very expensive, the highest conversion rate in 17%-20% efficiency is very low now, as the plant photosynthesis national clean energy, photovoltaic power generation policy is more than 10kW can free grid, but the recovery price is very low, cumbersome.

Q:How to choose a good use of solar energy

See building structureMulti story building: installation is not limited, vacuum tube solar energy and flat panel solar energy products can be selected. Senior and small high-level: balcony solar energy products can choose. Villa Construction: can choose to install flexible, can be integrated with the construction of flat panel solar energy, flat panel solar energy is not affected by high-rise and special buildings, beautiful and generous.See pipeBecause the water heater is often placed on the roof, there is a certain pressure and the house in the summer, hot water with high temperature (about 90 DEG C), the actual situation of low ambient temperature, so the best selection of crosslinking tube or plastic composite pipe or reinforced plastic hose. The utility model has the advantages of high pressure resistance, high temperature resistance, low temperature resistance, no toxicity, no odor, small heat capacity, small heat loss, and easy to freeze in winter.After-sale serviceThe best choice of well-known brands and the strength of dealers (longer distribution time, product quality complaints rate) of the water heater. Because the solar water heater is durable consumer goods, and usually installed in the roof, once the fault, it is difficult to deal with their own. So the customer service service must be guaranteed, at present, the whole market free warranty period of 3 - 5 years.

Q:The advantages and disadvantages of solar energy?Want to buy solar energy solar energy what is bad? Know about

You mean the solar water heaterSimply say:Benefits: power saving, safety,Disadvantages: 1, temperature affected by the weather,Because solar water heaters rely mainly on the absorption of sunlight, the light energy into electricity for heating waterSo the intensity of the sun directly affects whether you need to use electricity heating

Q:Solar energy product development prospects?

2 domestic solar water heater market development problems, intense competition. 2010 in the first half, the solar water heater industry ushered in the most severe market test, the number of manufacturers dropped from last year's more than 5 thousand to the current more than 2 thousand and 800. There are relevant data show that nearly 80% of the solar water heater companies have varying degrees of decline in sales, inventory increases and other issues, solar water heater industry's profits are getting lower and lower. In nearly 6000 domestic solar water heater business, really have the scale of production and R & D capabilities of enterprises less than 20, the rest for some local small workshops and brand-name enterprises. However, the quality of product inspection management, backward production technology, low price dumping, Jerry phenomenon in these small enterprises, resulting in solar water heater market order and chaos, there are many hidden dangers.

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: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: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 derived products The role of solar panels is to convert solar energy into electrical energy, the output of DC stored in the battery

Through the analysis of the site we came to the conclusion that the whole system we use wireless bridge hybrid network Winncam wireless bridge 2.4 and 5.8, from point to point and point to multipoint network, set up three level wireless transmission network, which can smooth the audio and video in the network through the front-end equipment; we recommend using infrared network the camera, rear end accept can use a computer, but also can use the DVR DVR to use the decoding function. Finally, we can view and manage the entire system at the back end. The most extensive application of solar energy in the early stage is to heat water, and millions of solar water heaters are now available all over the world. The main components of the solar water heating system include three parts: the collector, the storage device and the circulating pipeline. In addition, there may be auxiliary energy device (such as electric heaters, etc.) used to supply without sunshine, in addition still may have forced circulation with water, with water level control device or control electric parts or temperature and received loads of pipeline etc.. According to the cycle of solar water heating system can be divided into two kinds:
