Q:What are the references of the solar automatic tracking system
Tracking models were taken; gives the specific design ideas and methods of photoelectric tracking mode; to analyze and determine the sun trajectory calculation method, verified the feasibility of this method. According to the proposed tracking method, design a set of automatic tracking type independent solar photovoltaic power generation system. The system is a small photovoltaic power generation system based on automatic solar tracking, all-weather, high efficiency run independently, as much as possible the conversion of solar energy into electricity, to provide electricity load. The whole system is divided into automatic tracking system and two subsystems of solar photovoltaic power system, the photovoltaic power system is in the forest fire specific applications are analyzed and designed respectively. The design of hardware and software of the two subsystems. The hardware design includes the position of the sun and light intensity detection, calculation The software part of the system is designed, which is composed of computer control, data acquisition, external clock and photovoltaic power supply
Q:Outdoor solar energy products how to process the level of IP65
Sub form to be simple, the need to seal the place where the seal can not add the province.Second, is the protection of components, internal structure should pay attention to water and diversion, it is best not to enter the water.
Q:Now there is no sun, cloudy days can use solar products?
In addition, if you are a household, engage in electric heating can be complementary to each other!
Q:How much can the domestic high - temperature solar collector reach
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:Consumer behavior analysis of solar water heater
Competitor analysisThe solar water heater industry faces competition and substitute competition, has formed a professional brand, regional brand, brand and brand-name appliances co-exist in the market, the industry has fish, uneven in quality situation. With the competition and homogenization aggravating industry "reshuffle" is inevitable in the competition, need to break through the differences, creating a unique selling point, can focus on the product itself, can also be separated from the product itself, to create new demand from the consumer point of the competition range, consumers in the purchase of solar water heater in the purchase of solar energy is not, but convenient, safe, saving, healthy use of hot water. If you can surround the tube"
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:Advantages and functions of solar energy
The advantages of solar energy: solar energy as a new energy, compared with conventional energy it has three major characteristics: first, it is the most abundant energy source. It is estimated that in the past 1 billion 100 million years, the sun itself consumes energy in the future 2%. is sufficient to supply earth, using billions of years it is inexhaustible, inexhaustible.
Q:Solar energy items in daily life
Solar ice pad, solar panels, solar street lights, etc., are living in the solar green energy-saving products.
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: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
