Outdoor solar energy products how to process the level of IP65
- First, the packaging process,Design must consider the requirements of water, the structure can not be set up obstacless
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 ors
Buy solar water heater mainly look at what?
- Such a water tank, not only poor quality, but also may cause damage to the health of consumers with bacteria. Third, insulation layer. The quality and thickness of the insulation layer determine the insulation effect of the water heater. Now on the market most of the solar water heater using polyurethane foam insulation technology, but also the polyurethane material, but also the overall high pressure foam and low pressure foam. Large enterprises using the overall high-pressure foam to ensure the pressure and fullness of foam, a lot of small manufacturers of low pressure foam will be part of the insulation layer of the phenomenon of incomplete.s
Consumer behavior analysis of solar water heater
- Consumer behavior analysisConsumers in the purchase of products, often have to consider the physiological needs, safety and health needs, psychological factors (environmental sustainability, energy saving, economic and other factors), at the time of purchase, often face 5 kinds of risk perception: one is the financial risk, that there may be a waste of money; the two is the function of risk, if function is not so good, or no brochures and advertising on the good; three is the physiological risk, looks a bit dangerous, afraid might get hurt; four is the social risk evaluation from fear surrounding friends not good; five is the psychological risk, because buy guilty, it would be irresponsible. For solar products, because the product and installation specification is not perfect, the implementation of the implementation of the lack of supervision, consumers lack of understanding of the core technology of solar energy, solar water heater does not have a clear understanding, in order to "Huiyanshizhu, consumers in the purchase, will be the main value of the brand, including corporate brand, product brand and service brand is the basis for the choice of consumers, because the brand is a commitment to consumers, its excellent quality, strong customer service service will guarantee the legitimate rights and interests of consumers; the value of quality products, to effectively meet the target market demand, such as the market part of the solar water heater can meet the demand of hot water in summer. But one winter has become idle goods, and even pipe cracking; value service, service satisfaction value, such as" Baidu service 100% satisfaction, service a little more satisfied with a little, through the service to reduce the risk of consumer awareness of the purchase.s
What are the third generation solar cells
- In 2004, Professor Green proposed the idea of developing the third generation solar cells. If we apply the semiconductor crystal film solar cell is called the first generation of solar cells, thin film solar cell is called the second generation solar cell, then the third generation solar cell solar cells the next generation is expecteds
How about the effect of wall hanging solar energy
- Wall type solar water heater can belong to the separated type solar hot water system, water tank placed in the balcony or exterior wall, the collector is placed at the south facade of building a balcony wall hanging type solar water heater with flat collector to absorb solar radiation into heat, heat to reach the water tank and the water heat exchanger, so that the temperature of the whole the water tank is increased gradually, let the user can enjoy free hot water from the sun.The successful use of plate heat exchanger technology in wall mounted solar products, not only improves the thermal efficiency of balcony wall products, and the successful implementation of the building safety products and life integration, so that the water heater installation expanded to all floors and is not limited to the roof, and greatly lifted the traditional solar water heater, frozen fried tube, easy Water Leakage, easy scaling problems.s
How much can the domestic high - temperature solar collector reach
- Solar thermal power can be divided into three categoriesTrough system, tower system and dish system, they all belong to medium and high temperature system,Trough system is relatively popular in the other two categories, but also the most promising class. Operating temperature of 400~700 degrees Celsius, the scale is not limited to a few dozen megawatts, up to the level of Gigabit, there are some examples of successful commercial operation abroad. There are many prototypes in China, but there is no practical system.s
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 threes
