The smallest has 18. Solar power on the market today typically has 18, 20, 24, 30 or 36 tubes. If you want more, you can choose to do the project and have as many tubes as you want. Solar energy is a renewable energy source, which refers to the energy of thermal radiation from the sun (see the three modes of thermal energy transmission: radiation). The main manifestation is often called sunlight, which is used in modern times to generate electricity. or provide energy for water heaters.
These are three questions, please answer them separately:
At present, the thermal insulation effect of the water tank of solar water heaters is very good. The thermal insulation wall or. no thermal insulation wall has poor thermal insulation effect. The difference is not obvious. Under normal circumstances, the water temperature inthe solar water heater tank will drop approximately 10 degrees throughout the night.
If a 36 tube solar water heater is installed with normal configuration, the water tank capacity should be around 250L. Based on water consumption of 50 at 80 L per person, it can provide water for 3 to 5 people. people.
Typically in the south, the shower temperature is around 30 degrees, while the water temperature in a solar water tank is usually above 55 degrees on a sunny day. If it's a shower, that may be enough. 5 to 8 people depending on the ratio.
