Q:Monocrystalline silicon market when the turnaround, to what extent

From the current technology development and application prospects, I believe that solar energy has the most opportunity to become the world's major alternative energy sources. 1, the whole world light is rich in resources, solar energy is inexhaustible, inexhaustible solar energy; 2, technology and talent in the world of IT technology talents emerge in an endless stream, transferred to the solar technology, solar photovoltaic industry and the IT industry is very similar to that of solar grade polysilicon and electronic grade polycrystalline silicon thin film technology is the extension of a. From the LCD technology, therefore, the solar photovoltaic technology upgrading is very fast, the power generation efficiency of photovoltaic cells is also more and more high, more and more low cost at the same time, smart grid and energy storage technology will further enhance the application of solar energy, the development of space is very large, and is not affected by resource constraints and resource prices, if a stable price support, can maintain long-term fixed income, therefore, the solar power industry as the development of financial products, insurance funds will be favored;

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:How to choose a good use of solar energy

See building structureMulti story building: installation is not limited, vacuum tube solar energy and flat panel solar energy products can be selected. Senior and small high-level: balcony solar energy products can choose. Villa Construction: can choose to install flexible, can be integrated with the construction of flat panel solar energy, flat panel solar energy is not affected by high-rise and special buildings, beautiful and generous.See pipeBecause the water heater is often placed on the roof, there is a certain pressure and the house in the summer, hot water with high temperature (about 90 DEG C), the actual situation of low ambient temperature, so the best selection of crosslinking tube or plastic composite pipe or reinforced plastic hose. The utility model has the advantages of high pressure resistance, high temperature resistance, low temperature resistance, no toxicity, no odor, small heat capacity, small heat loss, and easy to freeze in winter.After-sale serviceThe best choice of well-known brands and the strength of dealers (longer distribution time, product quality complaints rate) of the water heater. Because the solar water heater is durable consumer goods, and usually installed in the roof, once the fault, it is difficult to deal with their own. So the customer service service must be guaranteed, at present, the whole market free warranty period of 3 - 5 years.

Q:Buy solar water heater mainly look at what?

Two, after-sales service is very important in accordance with the three products, the principle of service of seven points. After sales service in the choice of solar water heater also plays a big role. With the development of solar energy industry, more and more manufacturers, in these new manufacturers, many do not have plant equipment, parts to take OEM processing, business variables, quality is difficult to guarantee. Due to the small sales, when operating for a period of time after a loss and product quality problems, will run away. The products are sold without service. So in the choice of solar water heaters, the choice of large brand products is essential.

Q:30MW solar thermal power plant total investment

0MW total investment in solar thermal power plants:Solar thermal power generation units at home and abroad to invest 1.5~3 yuan /kW range, so 30MW power plant is currently estimated to invest 5-9 billion yuan RMB.

Q:Solar products must be in the sun

Solar energy products are generally inseparable from the sun, but there are also some of the solar radiation energy demand for smaller products

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:Solar heating easy to use? Has anyone used it

Advice do not believe! Solar heating is just a concept in china. In theory, in northern China, walls, windows and doors insulation to do a very good case, a square meter of solar collectors up to 3 square meters of heating area. If your house is 90 square meters, according to this calculation, you need to have 30 square meters of solar collector area
