Q:What are the disadvantages of traditional solar water heater

As a developing product, solar water heater is not perfect. People are skeptical about solar water heaters, solar water heaters can normal water supply, can bring convenience to life?

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

China's solar photovoltaic industry is not a bright prospect of solar photovoltaic industry competition and traditional fossil energy competition. As a result of fossil fuel causes global warming, the world is looking for new alternative energy program, the EU put forward in 2020, the substitution of renewable energy to reach 20%, 2050 reached 80% - 100% plan, Chinese also proposed in 2020 reached 15% China the proportion of non fossil energy, so in the future alternative energy plays a leading energy what is energy?

Q:Solar electric vehicle charging device

Performance characteristics of solar charger for electric vehicle:1 suitable for 36V, 48V configuration of the electric vehicle voltage conversion2 unique electric vehicle battery repair function, because of its continuous battery to supply electric power to prevent and remove the battery plate sulfide, recovery of battery capacity, prolong battery life, reduce the economic burden of the users.3 using the level of intelligent tracking system, the use of a new track concept, to achieve a day in the system of the sun's automatic tracking, improve the photoelectric conversion rate, increase the power supply to the battery.4 unique overvoltage protection technology to ensure the safety of charging equipment.

Q:What are the functions of the new vehicle negative ion solar charging humidifier?

Brown vehicle negative ion solar charging humidifier, in addition to negative ions and solar charging function, but also can be used as car fragrance, you can add essential oils.

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:What are the third generation solar cells

The physical connotation contained in it is: should keep the advantages of the second generation thin film solar cell with low cost, and is much higher than the Shockley-Queisser limit (32.8%) high efficiency, stable and reliable performance and the battery and battery rich material sources. In other words, the so-called third generation solar cell is a kind of high efficiency, low cost, long life, non-toxic and high stability of the near ideal photovoltaic solar cells."

Q:The best authoritative research report, even if their YYThank you for the answer to the first floor, but I found the 2000 water heater Research Report, although a bit long, but you can also use

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: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:Good solar polymer or monocrystalline

Spark solar energy products are also exported to many countries and regions such as Italy, Hongkong, Taiwan, the United States, Japan, Korea, Germany and other regions. After years of continuous development and improvement, not only to ensure good quality requirements, and won the domestic and foreign business partners to praise and affirmation. Stand on your point of view the factory must promise: fast delivery! Quality assurance! Price service is good. This season can undertake a large number of solar panels. This product can be customized for the price can also be agreed! Welcome to inquire or visit our company to discuss cooperation!

Q:How to make solar energy?

Finally, cut a large hole in the box and put on a plastic wrap to absorb sunlight. A simple solar water heater is finished. I do the "solar water heater" to the teacher. The teacher said: "you have not put black metal bottles, so absorb sunlight more slowly, the water temperature is not easy to rise." So, we put the bottle of black metal.
