1. It's best not to leave it on all the time. If it's frozen, if there is a heat tape, you can open the heat tape to thaw it, but someone has to watch it, because the heat tape can do that. easily cause a fire.
2. It is best to leave it empty in winter. If it is filled with water, it will freeze and easily cause the heat absorbing tube to freeze and crack. It is necessary to cover solar energy. with a cardboard box or other covering to avoid air drying.
3. The thermal performance of all sensors decreased after air drying. The thermal efficiency of the solar collector before air drying meets the requirements of national standards, but the thermal efficiency of the solar collector after air drying does not meet the requirements of national standards.
4. This type of air drying problem will not occur with ceramic solar. It's about asolar energy integrated into the building, it has the same lifespan as the building and resists air drying. This won't happen with conventional solar power. If you are concerned about the problem of sun exposure, you can search 丷黑丷黄金丷老丷人丶.
Why can't solar water heaters be used for drying in summer?
Solar energy can be dried in the air without water, but solar energy cannot be exposed to high temperatures and water.
Solar energy refers to the energy of thermal radiation from the sun, which is expressed mainly in the form of solar rays. In modern times, it is generally used to generate electricity or provide energy for water heaters. With the decline of fossil fuels, solar energy has become a significant part of human energy consumption and continues to grow. There are two meniers to use solar energy: photothermal conversion and photoelectric conversion. Solar power generation is an emerging renewable energy source. Solar energy in a broad sense also includes wind energy, chemical energy, hydropower, etc. on earth.
1. If it is in the north, it should be left empty. Filling it with water will freeze, which can easily cause the heat absorbing tube to freeze and crack. cover the solar panel with a cardboard box or other covering to prevent it from being exposed to sunlight.
2. The thermal performance of all sensors decreased after air drying. The thermal efficiency of the solar collector before air drying meets the requirements of national standards, but the thermal efficiency of the solar collector after air drying does not meet the requirements of national standards.
3. This type of air drying problem will not occur with the eneceramic solar energy. This is solar energy integrated into the building, it has the same lifespan as the building and resists air drying. This won't happen with conventional solar power. I'm afraid of air drying.

Advantages of solar energy
1 Universal: The sun shines on the earth without geographical restrictions, whatever the situation. land or ocean is everywhere, no matter mountains or islands, it can be directly developed and used, easy to collect, and does not require mining or transportation.
2. Harmless: The development and use of solar energy will not pollute the environment. It is one of the cleanest sources of energy today, while environmental pollution is becoming more and more serious.
3. Huge: The energy from solar radiation that reaches the Earth's surface each year is equivalent to approx.ron 130,000 billion tons of coal. Its total quantity is the largest energy that can be developed in the world today.
