FAQ

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.
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.
Solar electric vehicle charging device
Electric vehicle using solar silicon and polysilicon combination surface for Ling lighting plate, high quality and high efficiency crystalline silicon plate, the weak light response is very good, high photoelectric conversion efficiency, both indoor and outdoor sunlight, can be 24 hours of uninterrupted charging for electric vehicles to absorb light, can meet the different electric vehicles with electric load.
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.
The best authoritative research report, even if their YYThank you for the answer to the first floor, but I found the 2000 water heater Research Report, although a bit long, but you can also use
Competitor analysisThe solar water heater industry faces competition and substitute competition, has formed a professional brand, regional brand, brand and brand-name appliances co-exist in the market, the industry has fish, uneven in quality situation. With the competition and homogenization aggravating industry "reshuffle" is inevitable in the competition, need to break through the differences, creating a unique selling point, can focus on the product itself, can also be separated from the product itself, to create new demand from the consumer point of the competition range, consumers in the purchase of solar water heater in the purchase of solar energy is not, but convenient, safe, saving, healthy use of hot water. If you can surround the tube"
How to make better use of solar energy
The history of modern solar energy can be calculated from the 1615 French engineer Solomon de Cox in the world invented the first solar powered engine. The invention relates to a machine for pumping water by using solar energy to heat air to make it work. Between 1615 and 1900, the world has developed a number of solar power devices and other solar devices. Almost all of these power plants by condensing method to collect the sunlight, engine power is not the working fluid is mainly water vapor, the price is expensive, little practical value, for the majority of fans of solar energy manufacturing. Twentieth Century 100 years, the history of the development of solar energy technology can be divided into seven stages.
30MW solar thermal power plant total investment
0MW total investment in solar thermal power plants:Solar thermal power generation units at home and abroad to invest 1.5~3 yuan /kW range, so 30MW power plant is currently estimated to invest 5-9 billion yuan RMB.
Advantages and functions of solar energy
The technical field of solar energy utilization: only use solar energy there are three major technology areas, namely solar thermal conversion, conversion and optical shop in addition, photochemical conversion, and energy storage technology. The solar photoelectric conversion, mainly various types of solar panels and solar cell power supply system is to convert sunlight directly into electricity a device can the photoelectric efficiency of the solar cell is about 10-14% and its products are the main types of monocrystalline silicon, polycrystalline silicon and amorphous silicon. The domestic product (of a photoelectric device full cost) the price is about 60-80% yuan / Watt Peak. The scope of application of solar cell is very wide. Such as satellites, unmanned weather station, communication station, television relay station the sun, clock, electric poles, black lights, navigation lights, railway signal lights. Solar thermal conversion technology. Most of the products such as water heaters, boiling water heaters, dryers, refrigeration and heating, greenhouse and solar house, Solar range and high temperature furnace, seawater desalination device, water pump, thermal power generation device and solar energy medical appliance
