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:What are the references of the solar automatic tracking system
This paper studied the sun automatic tracking of the independent photovoltaic power generation system based on solar photovoltaic power generation as an important way of utilization of solar energy, the development prospects are very broad. At present, the photovoltaic power generation system with fixed form, the power system has the disadvantages of low power efficiency, high cost and difficult to promote.
Q:What is the difference between photovoltaic products and solar energy?
Photovoltaic and solar energy is a concept.Photovoltaic (Solar Power): solar photovoltaic power generation system (Solar power system) for short, is a kind of semiconductor material using solar photovoltaic effect, will be directly converted to a new generation of electric power system with solar radiation, operate independently and grid connected in two ways.
Q:Solar industry products trade prospects
Yes, for example, solar lights, developing and developed countries are in great demand
Q:Household solar energy productsThe product can be used at home, do not mention the solar energy, answer the water heater
Divided into two large photovoltaic and thermal.Photovoltaic power plant used in the battery board has two kinds of polysilicon and monocrystalline silicon, which is a little higher conversion rate. A solar photovoltaic system of solar power generation system, glass curtain wall, large on / off grid systems (e.g. Tibet Yangbajing engineering). In addition, there are solar street lights, scenery complementary street lights, solar lights, solar LED screen, solar backpack, etc.
Q:What are the solar products?
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:How to make solar energy?
Do experiment. We put the foil affixed to the box, to reflect sunlight. Then put the metal bottle full of water in the box and secure it with a plastic foam.
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:The steps of making solar technology stubs
Material Science:Black plastic bag, rope.Making method:The black plastic bag filled with water after the bag tied in sunlight (see photo). After a while, the bag of water on the heat, can be used to wash your face, wash your feet.3 material: walnut, stick, rubber mud, small cloth.
Q:Is there any water in the solar energy to water?
Yes, but it's best not to add water during the day
