Q:Solar energy has some disadvantagesDetailed description of the problem, to help the respondents give accurate answers
Second, the earth, no matter where there are solar energy, can be developed and used in the field, there is no transport problem, especially for the underdeveloped rural areas, islands and remote areas have more value. Third, solar energy is a clean energy, in the development and utilization, will not produce waste residue, waste water, waste gas, no noise, but will not affect the ecological balance.
Q:Is there any water in the solar energy to water?
How much is the automatic water supply set level up to the number 2 can not need to fill 100 set automatic water temperature time to remove any fill
Q:What is the future of solar power
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. According to the State Administration of taxation policy released last year, from October 1, 2013 to December 2015 3l, according to the 3% levy rate calculation. In Takamatsu as an example, if a month sales of 30 thousand, that he should pay the tax is 30 thousand x 3% x 50%=450 yuan.
Q:Solar energy application technology, there is no prospect
At present the solar energy situation is not optimistic, the Americas and Europe has Chinese solar "double reverse" and China internal and not good, can not be the own production of solar energy products consumed, resulting in pile up in excess of requirement. Therefore, many Chinese solar manufacturers have closed down.
Q:The steps of making solar technology stubs
1 with a brush clean eraser material: big eraser, waste brush.Tools: scissors, glue.
Q:What is the difference between photovoltaic products and solar energy?
But in general, as many of the world's oil and gas production areas of political and economic instability, many governments are taking active measures to reduce dependence on foreign energy sources. Solar energy provides an attractive power generation program, and will not form a serious dependence on foreign energy. In addition, the increasingly serious environmental problems and fossil fuel power and political reasons of climate change risk formation, prompted the government to implement the aims to reduce carbon dioxide and other greenhouse gas emissions reduction strategy. Solar energy and other renewable energy sources contribute to the solution of these environmental problems.
Q:Household solar energy productsThe product can be used at home, do not mention the solar energy, answer the water heater
What solar products:The current solar products include: solar water heater, solar lamp, solar battery, solar power, solar fan cap, solar fan, villa solar power systems, solar flashlight, solar charger, solar cars, solar powered aircraft etc..The main components of solar water heater: flat solar water heater, vacuum tube solar water heater, wall mounted solar water heater.Solar lights include: solar street lights, solar garden lights, solar home lighting.Solar cells are: silicon solar cells, multi compound thin film solar cells, nano crystalline solar cells, organic solar cells.
Q:30MW solar thermal power plant total investment
At present, there are three kinds of solar cells, such as monocrystalline silicon, polycrystalline silicon and amorphous silicon. Monocrystalline silicon solar cell conversion efficiency of up to 20%, but the price
Q:PV solar products market sales
According to the State Administration of taxation policy released last year, from October 1, 2013 to December 2015 3l, according to the 3% levy rate calculation. In Takamatsu as an example, if a month sales of 30 thousand, that he should pay the tax is 30 thousand x 3% x 50%=450 yuan.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
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.
