Q: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..

Q:Now there is no sun, cloudy days can use solar products?

At present, I have not found this kind of solar energy

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:How to do a good job of solar water heater marketing?

First, environmental protection: vacuum tube solar water heater purchase tips. According to the calculation, each household solar water heater during its 15 years of use, will reduce the coal to atmospheric carbon dioxide emissions of 26 tons, 136 tons of carbon monoxide, dust 1120 tons, 352 tons of sulfur dioxide, 908 tons of nitrogen and hydrogen compounds, this is not a small number of residents in our Province, in the subtropical zone. Suffering from the hot days of suffering, such as the province's residents are using solar water heaters can reduce the average temperature of 1 degrees, so the use of solar energy, make the sky bluer, mountains greener, the water clearer, gas cooler, is an effective measure of green environmental protection.

Q:Product category and comparison of solar thermal utilization

The solar industry did a survey on the overall evaluation of the use of solar energy users, think very satisfied with only 3.5% basic satisfaction was 12.6%, average and unsatisfactory accounted for 35.2% and 48.7%; the user evaluation of the service, satisfied and satisfied for a total of 24%, and that no service dissatisfaction accounted for 76%.

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:Solar energy items in daily life

Solar ice pad, solar panels, solar street lights, etc., are living in the solar green energy-saving products.

Q:Advantages and functions of solar energy

Second: the earth, no matter where there is solar energy can be in situ development and utilization, there is no transport problem, especially for trafficunderdeveloped rural areas, islands and remote areas had more use value. Third: solar energy is a kind of clean energy. In the development and use, does not produce waste residue, waste water and gas, also there is no noise, but will not affect the ecological balance. Absolutely not cause pollution and pollution.

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

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

Q:Is there any water in the solar energy to water?

In the case of water inside the solar energy can also be irrigated 1,
