How to promote the use of solar energy in China

Overall, the use of solar energy is still very fast, or how the United States will be on China's solar energy products to ban it? As for the overall development of the domestic solar energy industry is good, but still need to do a lot of work. For example, how to improve the quality, efficiency, etc..

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.

Solar panels with single crystal silicon or good thanks

Single crystal or polycrystalline good?Many of my friends would ask is good or good crystal crystal, we many people buy just as ordinary lighting and small system to watch TV, to tell the truth this is really no need to care about the single crystal or polycrystalline, regardless of the need is a power is enough, two is the price is good!

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.

1 natural circulation:This type of storage tank is placed above the collector. Water heating collector in solar radiation temperature rise, causing the collector and tank water temperature and have a different density difference, thus causing buoyancy, this is like a hot siphon, the water flow in the water storage tank and collector. Because of the density difference, the water flow rate is proportional to the solar energy absorbed by the collector. This kind of type is widely used because it does not need the circulating water and the maintenance is very simple.2 forced circulation:The water in the hot water system makes the water circulate between the collector and the water storage tank. When the water temperature at the top of the collector is higher than the water temperature of the bottom of the water storage tank, the control device can start the water to make the water flow. A check valve is arranged at the entrance of the water to prevent the nighttime water from being driven by the collector to cause heat loss. The flow rate of this type of hot water system can be known (as a result of the flow from the water), easy to predict performance, can also be calculated in a number of hours of heating water. As in the same design condition, the natural circulation has can gain higher water temperature strengths, but because it must use water, the water power and maintenance (such as Water Leakage etc.) and the control device of dynamic stop, damage easily water problems. Therefore, in addition to large hot water system or the need for a higher water temperature, the forced circulation, the general use of natural circulation water heater. Solar power system consists of solar cells, solar controller, battery (group). Such as output power for AC 220V or
