Can solar water heaters produce electricity?

Hello, solar water heaters heat hot water through collector tubes, but now there is also solar energy that can produce electricity, but the technology is not yet mature!

Recommended "Dr. Sun" solar energy, three warehouse models (no need for water level probes and solenoid valves), heating and hot water utilization rates are fast in rainy weather, and the after-sales service rate is also greatly reduced, saving time. It also saves electricity. This model only takes 20 to 30 minutes to heat without sunlight, while a single warehouse takes 2 to 3 hours

< p>The role of solar energy

1. It can be used to maintain health

Sunbathing refers to the method of using the sun to irradiate the human body to treat diseases and promote health. recoveryphysical and mental ion. It is also called "sunbathing", the human body is not only affected by infrared, visible and ultraviolet rays contained in the sun, but also by air temperature, humidity and other meteorological factors .

Therefore, the impact of sunbathing on health is multifaceted. Studies have shown that moderate exposure to sunlight can dilate blood vessels in the skin, promote metabolism, improve skin function, and make skin healthy.

2. It can be used to generate electricity

Solar energy. “Inexhaustible and inexhaustible”, we can say that it is one of the most abundant sources of energy in nature. The use of solar energy is also the key to solving energy problems. At present, human development and the use of solar energy still suffer from low efficiency, scattered radiation,n insufficient energy storage and many other faults. The ideal photothermal solar fuel will enable reversible energy conversion and storage within a single material system, with zero emissions, easy transportation, recyclability, reproducibility and thermal stability. Solar thermal fuel has therefore become an important goal for scientists. in the whole world.

3. Variable solar fuel

The reason green leaves can photosynthesize. The key to turning carbon dioxide in the air into oxygen depends on two things. is that two molecules in the leaves absorb sunlight, and the other is that two catalysts convert sunlight. The equipment they developed simulates green leaves and relies on silicon to absorb solar energy. p>

Disadvantages of theSolar Energy Industry

International Energy Price Trends The economic downturn has had a serious impact on new energy industries. like solar energy. The higher the price of traditional energy, the greater the development space for new energy. At present, due to the combined effects of many negative factors such as continued weakness in global crude oil demand and the shale revolution, solar energy, etc. Times are very difficult for the new energy industry.

Second, the previous development model of the solar energy industry was unsustainable due to the rising prices of traditional energy sources such as oil, natural gas and solar energy. coal. It is becoming more and more popular, and the solar energy industry is not only developing relatively quickly, but reaching equalement the overheating level. After more than 20 years of development, the solar power industry has entered a period of restructuring. the pace of survival of the fittest continues to accelerate.

Facing fierce competition in solar photovoltaic products, polysilicon production is located upstream of the solar industry. Facing the cold winter of the solar industry, the demand for polysilicon from photovoltaic manufacturers around the world is relatively low.
