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:Now there is no sun, cloudy days can use solar products?: At present, I have not found this kind of solar energy

Q:Monocrystalline silicon market when the turnaround, to what extent: 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:What is the future of solar power: 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. In accordance with the same calculation method, 10 kilowatts of distributed photovoltaic power generation device to recover the cost of 9-10 years. Family photovoltaic power plant to recover the cost of an average of between 8-10 years.

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 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:What are the functions of the new vehicle negative ion solar charging humidifier?: Brown vehicle negative ion solar charging humidifier, in addition to negative ions and solar charging function, but also can be used as car fragrance, you can add essential oils.

Q:Product category and comparison of solar thermal utilization: What is the reason?The main reason is that China's solar energy (water heater) is the most in-line vacuum tube solar water heater, vacuum tube itself is vulnerable, tube explosion caused by vibrations, icing, improper water and other reasons, the vacuum tube fouling phenomenon is very serious, affecting the normal use, needs a great amount of customer service service, high maintenance costs. Once, encountered bad weather, frequent accidents, too busy to attend to all enterprises and dealers.Where is the way out?According to the experience and lessons of foreign countries, the use of a new type of high-performance flat solar energy is the most feasible and effective solution.

Q:For example, solar flashlight, solar watches and other small solar products are what? Shenzhen where can be approved...: Solar water lamp power supply, inverter solar watch packaging glass packaging film melted material monitoring system wiring box of solar wind cap regulator controller

Q:Or must there be built - in battery? If yes, then use the mobile phone lithium battery can?: Mobile phone battery as an energy reserve, but no 5V output boost function, the same can not charge the phone. If you have bought a solar panel, you can buy a mobile power with the use of
