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: (1) solar panel: solar panel is the core part of solar power generation system, also is the most 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. (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 when the controller is optional; (3) battery: general for lead-acid batteries, small miniature system, also can use nimh batteries, nickel cadmium battery or lithium battery. Its role is solar electric panels under illumination of electricity, to release when needed. (4) inverter, solar direct output is usually 12 VDC, 24 VDC, 48 VDC. To provide electricity to 220 vac electrical appliances, you need to solar power generation system of direct current (DC) can be converted into AC power, so you need to use DC - AC inverter. Solar power system design factors to consider: 1, where is the use of solar power system? How is the area solar radiation? 2, the system load power? How much is 3, the system output voltage, dc or ac? 4, the system need to work how many hours a day? Wet weather in 5, if there is no sunlight, continuous power supply system need to how many days? 6, load, pure resistive, capacitive or inductive, starting current how old? 7, the number of system requirements


Divided into solar-thermal power generation and photovoltaic solar power. Usually said solar power refers to the solar photovoltaic power generation, hereinafter referred to as \"pv\". The light of the photovoltaic power generation is to use semiconductor interface will be born v effect in a technology light energy directly into electrical energy. The technology key element is the solar cell. Solar cells after a series of packaging protection can form a large area of solar cell components, combined with power controller and other components are formed on the photovoltaic device.

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:What about solar products?Solar panels solar panels
As long as the need to get electricity can. Solar lamp (lamp, landscape lamp, lawn lamp, flashlight, camping lights, lights and so on...), power generation system (Canada now many private power, is the placement of solar panels in the roof)...
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?
The amount of radiation of solar water heater is the meaning of the sun. The sun did not reach that he cannot.
Q:Monocrystalline silicon market when the turnaround, to what extent
The world climate change, because solar energy is a one-time investment, the current data show that solar power business life cycle for 25 years, before 3 - 5 years for solar power plant manufacturing cost, the carbon dioxide produced far less than the size of the fossil power plant, therefore, the climate change and carbon dioxide emissions contribute to global; 4, the application prospect of solar energy is very extensive, both the roof power station, large-scale solar power plants, or used in human life will be very popular, the power system involves the possible and the sun can be combined.
Q:Solar energy product development prospects?
Summary: at present, the country's top ten brands of solar companies together market share is less than the national market of 10%, companies want to get a larger market share is difficult. Domestic solar water heater market development problems, intense competition. Local laws and regulations activate the project market, the development of the industry ushered in new growth, the rapid development of solar water heating system engineering market, government policy support. The pain of the industry - too frequent flow of talent. The flow of talent of the solar water heater industry is too frequent, among enterprises personnel frequent job hopping, which is harmful for the development of enterprises, but also bring the product homogeneity and marketing homogeneity consequences, market promotion means that the same product function and price of roughly the same situation.

Q:Solar energy products, that is, I would like to open a home solar products Daquan
You come to buy a small brand, I guarantee the same brand and the water temperature. There ah, is to buy low in quality, the water temperature is much higher than the big brands, better quality, but the price is low. This is the answer to the water heater. Now I have to answer your question: I think a large and complete solar business success is unlikely, because you can do fine, because no sales manufacturers will hate you, you will not get a low price, so in the competition you will be in a passive position. There is a large investment in the business field, but this is taboo, because you invested huge output and small, out of proportion. As the election, do fine, do in this field, you are the boss. Others want to see your face. You can make a big profit this time.
Q:Or must there be built - in battery? If yes, then use the mobile phone lithium battery can?
Solar panels because of light effects, such as shadow, the angle, so the output voltage is not stable, not stable in 5V, generally with a simultaneous mobile power output and input to the panel itself has a built-in battery, then of course better.
