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:What are the current domestic solar energy products, which practical
Photovoltaic power generation system is mainly composed of solar cells, batteries, controller and inverter, the main part of solar cells. In the application of more public amenities such as solar street, home of the little, of course you can install the system of solar photovoltaic panels at home, 1W about ten dollars, plus the controller, you can see if you are able to supply applications at home how much money.
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 photovoltaic products and solar energy?
Photovoltaic and solar energy is a concept.Photovoltaic (Solar Power): solar photovoltaic power generation system (Solar power system) for short, is a kind of semiconductor material using solar photovoltaic effect, will be directly converted to a new generation of electric power system with solar radiation, operate independently and grid connected in two ways.
Q:Consumer behavior analysis of solar water heater
Please look at the following article, how, I hope to help you.Along with the development of circular economy and energy-saving society, harmonious society, promote the development of renewable solar energy will further deepen and utilization, a huge space for development of the solar water heater manufacturers are increasing, the solar water heater manufacturers more and more in the current imperfect and immature market competition is intense, and even had a "bad money drives out good money" phenomenon, in the homogenization of the competition is a piece of the Red Sea, currently on the market on the one hand is the electric water heater, gas burner and solar water heaters on the other hand is a situation of tripartite confrontation, many district or city because of the "City" to the solar water heater, coupled with low barriers to entry and not mature consumer environment, frequent occurrence of water heater on the market collapsed, Water Leakage, no hot water phenomenon, making consumers. Solar water heater to break through the market, the need for in-depth market analysis, market segmentation, innovative marketing strategies, and then win the market.
Q:Solar energy has some disadvantagesDetailed description of the problem, to help the respondents give accurate answers
Solar energy as a new energy source, it has three advantages compared with conventional energy:First, it is the most abundant energy that human beings can use, it is estimated that in the past 1 billion 100 million years, the sun consumes its own energy of 2%, can be said to be inexhaustible.
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:Solar panels with single crystal silicon or good thanks
Working principle: sunlight to the solar cell plate produced by the current through the inverter controller of the battery, the battery power through the inverter controller into DC or AC electric power supply (load), or through the grid connected inverter of direct energy input power grid. Solar photovoltaic system consists of solar cells, solar controller, battery (Group), such as the output power for AC 220V or 110V also need to configure the inverter. In the specific design of system engineering, the following factors should be considered: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;
Q:How to do a good job of solar water heater marketing?
Three, safety: non pressurized solar water heater working principle. Gas water heaters, electric water heater is widely used in the existing safety problems, the province each year due to the accident, use water heater to cause death in 5 cases above, and with the increase of users, the number is rising, the use of solar energy does not exist poisoning and the hidden danger of electric shock, very safe, even if the solar water heater electric heating function, because the heating body away from the user, coupled with the use of time is only 1/10 of the electric water heater, so the possibility of harm has reached very little and negligible.
Q:How much does it cost to install solar energy in rural areas
Four look at the brand, service. The solar water heater host outdoors year-round by professionals need to withstand exposed to wind and rain, maintenance, maintenance. At present, there are 4000 domestic solar water heater factory, as the country has not yet unified solar water heater testing standards, some of the quality of the product does not pass, installation services are not in place, to bring trouble to users. Buy solar energy is not only a product, but more importantly, service". Therefore, we should choose the strength of the brand name of professional manufacturers of products, such manufacturers to install service personnel are generally through professional and technical training, service and thoughtful, so that you do not worry, get the best protection.
