Q: Solar products must be in the sun
Energy (Solar), generally refers to the sun's radiant energy, passive use (photothermal conversion)
Q: Product category and comparison of solar thermal utilization
What is the reason?The main reason is that China's solar energy (water heater) is the most in-line vacuum tube solar water heater, vacuum tube itself is vulnerable, tube explosion caused by vibrations, icing, improper water and other reasons, the vacuum tube fouling phenomenon is very serious, affecting the normal use, needs a great amount of customer service service, high maintenance costs. Once, encountered bad weather, frequent accidents, too busy to attend to all enterprises and dealers.Where is the way out?According to the experience and lessons of foreign countries, the use of a new type of high-performance flat solar energy is the most feasible and effective solution.
Q: In the domestic high temperature solar energy collector can achieve how many degrees, the existing product and the technology form?
Above three types of high temperature system, although the operating temperature difference is not small, but the overall efficiency is not much difference, both in the 20~25%, and the temperature is high, the comprehensive efficiency is high, the business efficiency is not high.Low temperature solar thermal system, refers to less than 200~300 degrees Celsius, power is almost blank, because the theory of efficiency of solar thermal power generation system at low temperature is relatively low, but personally think that if the utility system developed a reasonable, the comprehensive efficiency and business efficiency is not low.
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: Solar energy products, that is, I would like to open a home solar products Daquan
I have two sets of solar home, one is Huang Ming, a sijimuge, later a temperature than the Emperor Ming of the seems to be a little higher, are also good, but home Taiwan Himin's high, I want to buy one, want to try another brand is not the same effect
Q: Or must there be built - in battery? If yes, then use the mobile phone lithium battery can?
. Cell phone lithium battery? Do you mean to put the mobile phone lithium battery on the solar panel? Do not Oh, can not be achieved, the direct use of solar panels charge mobile phone battery, then a little dangerous
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: What are the references of the solar automatic tracking system
Using solar automatic tracking in the photovoltaic power generation system, can effectively improve the utilization of solar energy. Therefore, the research in this paper to improve the efficiency of photovoltaic power generation, has important significance to promote the popularization and application of photovoltaic power generation. This paper proposes a photoelectric tracking mode and solar tracking combined all-weather solar the automatic tracking method. Analyzed and sunny, cloudy and rainy weather condition three
Q: Solar panels with single crystal silicon or good thanks
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: Outdoor solar energy products, how can we do the process of IP65 level, the design of the water which should be noted that what? Beg enlighten heroes!
First, the packaging process,Design must consider the requirements of water, the structure can not be set up obstacles
