In theory, photovoltaic power generation technology can be used for any occasions that we need the power supply to the spacecraft, down to the household power, big to megawatt power plant, small to toys, photovoltaic power everywhere. Photovoltaic solar cells is the most basic components (film), monocrystalline silicon, polycrystalline silicon, amorphous silicon and thin film batteries, etc. Among them, the single crystal and polycrystalline battery dosage the biggest, amorphous cell used in some small system and computer aided power supply, etc. Chinese domestic efficiency of crystalline silicon cells in 10 to 13%, the efficiency of the like product on international about 12 to 14%. Composed of one or more of the solar cells, solar panels, called the photovoltaic modules.

Solar power system consists of solar battery, solar controller, battery (group). Such as the output power for ac 220 v or 110 v, also need to configure the inverter. The role of each part as follows:

(a) solar panel: solar panel is the core part of solar power generation system, is also a valuable part of the solar system. Its role is to convert the sun's radiation ability of electrical energy, or sent to stored in batteries, or promote work load. Quality and cost of solar panels will directly determine the quality and cost of the whole system.

(2) solar controller: solar controller is used to control the working state of the whole system, and battery over charging protection, over discharge protection role. Where the temperature difference is bigger, qualified controller should also have the function of temperature compensation. Other additional functions such as light-operated switch, switch should be the option of the controller.

(3) battery: general for lead-acid batteries, small miniature system, also can use nimh batteries, nickel cadmium battery or lithium battery. Its effect is when a light will be made by electricity, solar panels to released when needed.

(4) inverter, on many occasions, all need to provide 220 v AC, 110 v AC AC power. Due to the direct output of solar are generally DC 12 v, 24 v DC, 48 v DC. To provide electricity to 220 v AC electrical appliances, needs to be given out by the solar power system DC can be converted into AC power, so you need to use DC - AC inverter. In some cases, it is necessary to use a variety of voltage of the load, also want to use DC - DC inverter, such as the 24 v DC power into 5 v DC power (note that is not a simple decompression).

Q:Home solar heating products can not mature?
1, the local climate: the solar water heater solar tube is not winter frost, but many people will find that in addition to solar tube other basically frozen broken in the actual use of the process, all the cold area, far distance roof is not recommended, the summer hail smashed zirendaomei. Before taking a bath before half a bucket of cold water, it is really a waste;2, installation conditions: the water pressure is not good, the floor is high, ready to install solar energy and electric hybrid proposal wash sleep. The related auxiliary equipment comprises a booster pump, a controller, will force you to spend a lot of innocent money, you are hard to feel the donkey3, economic price: the use of the price, the price of solar water heater in more than 3000, 1500 yuan, 2000 yuan while the gas water heater, solar electricity, but the experienced friends all know no electricity solar still can not be used, all can not talk about energy saving. On the use of the cost of natural gas pipeline gas prices in the province, followed by electricity tariffs, the overall cost of speaking, to buy more than 1500 yuan solar electricity tariff equivalent to 3000 degrees, enough for a few years of use.
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
