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: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.

Q:What are the forms of solar energy? My villa would like to design a comprehensive utilization of solar energy.

Solar hot water, solar photovoltaic power generation, various solar lamps

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

Two, energy saving (cost savings): the impact of solar water heater life components. About the use of solar water heaters for heating homes, can save daily for heating water electricity, gas costs 90%, can reduce household expenses, to the society, can reduce our province limited energy resources consumption, the energy and ancillary facilities for agricultural and industrial production, have greater social benefits.

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:Product category and comparison of solar thermal utilization

Why choose a new type of efficient flat plate solar water heater (device) system?In recent years, the use of solar thermal products in China has been rapid development. In the solar water heater manufacturing, use and market share, China has far ahead. However, due to the use of solar thermal products in domestic vacuum tube based, in full swing in the development of the industry, but also exposed a lot of worrying problems.

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

The solar water heater, solar flashlight, solar micro kitchen, decoration, solar car

Q:Good solar polymer or monocrystalline

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!The difference between polycrystalline and single crystal: single crystal plate is black, polycrystalline plate is blue or color.Disadvantages: the same power of the single crystal plate with polycrystalline plate, polycrystalline board area slightly larger than the area of single crystal board, the same as the 50W polycrystalline will be 1.1 times larger than the single crystalThe utility model has the advantages that the polycrystalline plate is a plurality of directions to receive light and has good directivity. The actual test, hypothesis with one hand to block the sun's rays to solar power on the surface of a shadow, so many crystal board power current decrease is not obvious, but the single plate power current is reduced obviously, this is the advantage of multi crystal plate.

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
