Solar Modules on Polycrystalline and Monocrystalline


Q: Do solar vacuum tubes require specific water chemistry?
Yes, solar vacuum tubes do require specific water chemistry. The water used in these tubes should be free from excessive calcium, magnesium, and other mineral deposits that can cause scaling on the inner surface of the tubes. Additionally, the pH level of the water should be within a specific range to ensure optimal performance and longevity of the system.
Q: Can solar vacuum tubes be used for solar-powered water pumping?
Yes, solar vacuum tubes can be used for solar-powered water pumping. Solar vacuum tubes can absorb sunlight and convert it into heat energy, which can then be used to power a water pump. This process is known as solar thermal water pumping and is an efficient and sustainable way to pump water using solar energy.
Q: Are solar vacuum tubes suitable for hospitals or healthcare facilities?
Yes, solar vacuum tubes are suitable for hospitals or healthcare facilities. They are a reliable and cost-effective source of renewable energy, providing hot water for various purposes such as sterilization, laundry, and patient comfort. Additionally, their efficient design allows them to work even in low light conditions, making them a viable option for healthcare settings.
Q: Can solar vacuum tubes be used for cooling purposes?
No, solar vacuum tubes cannot be used for cooling purposes as they are designed to capture and convert solar energy into heat, not to remove heat from a space.
Q: Can solar vacuum tubes be used in conjunction with a traditional water heater?
Yes, solar vacuum tubes can be used in conjunction with a traditional water heater. These tubes can be installed as a pre-heating system, where the solar energy heats the water before it enters the traditional water heater. This combination allows for more efficient and cost-effective water heating.
Q: What is the price of solar collectors
costInternal tube coating: 7.5 yuanOuter tube: 4 yuanVacuum plus other costs: 4 yuanFirst class wholesalers; increase of 5 yuanTwo wholesalers fare: 12 yuanRetail price: 20 yuanFinally to the hands of you probably, the general tube color [green black] 55 yuan, three high tube [blue] of $60, purple tube [gold] $65. Distinguish method: can be clearly distinguished by the naked eyeBut more than just the boss is not black price, such as the case of black, do not buy the best,For reference only
Q: Are solar vacuum tubes suitable for use in pharmaceutical manufacturing plants?
Yes, solar vacuum tubes can be suitable for use in pharmaceutical manufacturing plants. They can provide a cost-effective and sustainable source of hot water or steam, which is often required in various manufacturing processes. Additionally, solar vacuum tubes have efficient heat transfer capabilities and can operate even in low sunlight conditions, making them a reliable option for pharmaceutical plants.
Q: How do solar vacuum tubes compare to hydrogen fuel cells?
Solar vacuum tubes and hydrogen fuel cells are both renewable energy technologies, but they differ in their mechanisms and applications. Solar vacuum tubes are used to generate heat and hot water by harnessing the energy from sunlight, while hydrogen fuel cells convert hydrogen and oxygen into electricity and water vapor. In terms of efficiency, hydrogen fuel cells have a higher energy conversion rate and can provide continuous power, while solar vacuum tubes are more suitable for heating purposes. Additionally, hydrogen fuel cells require a constant supply of hydrogen, which can be challenging to produce and store, while solar vacuum tubes rely solely on sunlight. Overall, the choice between solar vacuum tubes and hydrogen fuel cells depends on the specific energy needs and available resources of the intended application.
Q: Home solar energyThe dirt in the pipe -- alkaliHow to clean up?I hope my friends can help me solve this problem..Thank you first..
With citric acid detergent. The specific operation: 1, with water into the barrel, adding citric acid detergent diluted to 1% solution. 2, according to the length of the vacuum tube, with a small steel pipe (1.2, 1.5, 1.6, 1.8, 2.1, 2.3m) connected with the cleaning brush, brush diameter than the diameter of tube 5-15mm (according to the vacuum tube with a diameter of 37, 47, 58, 70mm), easy to clean dirt.
Q: In the southern city, the average temperature in winter is between 20 degrees celsius.
20 branch of the solar water tank capacity of about 180L, wash 5-6 individuals should be able to. In winter, it's not every day
