What are the advantages of micro-power solar wastewater treatment equipment? Why does all the energy supply come from the sun during operation?

Firstly, it is widespread.

Sunlight shines on Earth, unbound by land or sea, high mountains or islands, and can be directly exploited without the need for extraction and transportation.

It is harmless.

Harnessing solar energy is a clean and environmentally friendly power source, which is invaluable in today's increasingly polluted world.

The third point is significant.

The solar radiation energy reaching the Earth's surface each year is approximately 130 teratons of coal, which is the total of the world's exploitable energy resources currently available.

Fourthly, longevity.

Based on the current rate of nuclear energy produced by the sun, the hydrogen supply is estimated to last for hundreds of billions of years. In this sense, it can be said that the sun's energy is inexhaustible.
