Product Description:

Photovoltaic power generation is by physical action, the solar energy directly into electrical energy directly to the process, does not produce any pollution and noise in the middle. Photovoltaic module is the core component of photovoltaic power generation systems, photovoltaic inverter is to produce direct current into alternating current (ac) devices, also is the important components of power systems.

According to whether the power grid, can be divided into two types of access, off-grid and interconnection. Off-grid belongs to the independent power supply system, from the power supply network; And photovoltaic power grid is the grid application way. Now, grid are the major ways of using photovoltaic (pv) power grid and can be divided into the ground power station and distributed.

Off-grid system consists of photovoltaic module, controller, inverter, battery and so on several parts. Have sunshine power generation, and the electricity is stored in the battery, the output electricity back on.

General large hydropower station on the ground, installed on the ground of large area, direct power grid; General installation and distributed power station in the family or the roof of the industrial and commercial buildings, is relatively small, hooked up to the grid at the same time, also for the building electricity. This two ways, the government subsidy standard is also different.

Q:How to promote the use of solar energy in China
In this regard, the government should do a lot of work, industry associations have also made the relevant advance
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:
Q:What about solar products?Solar panels solar panels
Solar modules on the equivalent of a battery, what the use of their own to think about
Q:How to develop solar photovoltaic industry
China's solar photovoltaic industry is not a bright prospect of solar photovoltaic industry competition and traditional fossil energy competition. As a result of fossil fuel causes global warming, the world is looking for new alternative energy program, the EU put forward in 2020, the substitution of renewable energy to reach 20%, 2050 reached 80% - 100% plan, Chinese also proposed in 2020 reached 15% China the proportion of non fossil energy, so in the future alternative energy plays a leading energy what is energy?
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: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:Solar energy has some disadvantagesDetailed description of the problem, to help the respondents give accurate answers
Disadvantages of solar energy:The use of solar energy has its drawbacks:First, the current density is low, the sun is better, the ground floor area of 1 square meters of energy received only about 1 kilowatts. It is often necessary to set up a large number of lighting surface to meet the use requirements, so that the large area of equipment, materials, cost increases.Second, the greater the impact of the atmosphere, to bring a lot of difficulties.
Q:Solar energy items in daily life
The solar water heater, solar flashlight, solar micro kitchen, decoration, solar car
Q:Solar energy products, that is, I would like to open a home solar products Daquan
I have two sets of solar home, one is Huang Ming, a sijimuge, later a temperature than the Emperor Ming of the seems to be a little higher, are also good, but home Taiwan Himin's high, I want to buy one, want to try another brand is not the same effect
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.
