How Does Evacuated Tube Residential Solar Water Heaters Work?

Solar collector is the engine of residential solar water heaters. Solar evacuated tubes have been producing solar power more efficiently than flat plate systems. With the increasing demands of solar energy and modern manufacturing techniques, the cost of solar vacuum tube technology provides you with the maximum return on your investment.

The working principle behind solar evacuated tubes is very simple. A solar vacuum tube works similarly like a coffee thermos. The solar evacuated tubes comprise of two glass layers with vacuum in between the layers. 

The external layer of the solar tube is made from borosilicate glass which has very low iron and allows 98% light energy to enter through. The second internal layer has the special coating applied to it. 

The SunRain solar vacuum tubes utilize a three-layer patented process that provides a coating to absorb more solar energy. Hence, they can withstand excess 300 degrees temperatures efficiently. The coating makes the solar collectors stand out from others available on the market. 

However, the special coating transforms the short wave solar radiation into longwave heat radiation. Remember that, the solar vacuum tube is almost 94% efficient which means only 6% of solar energy is lost. 

The absorbed solar radiation is again transferred to a heat transfer fluid within the tube. The liquid heats up faster and goes to the top. In an open vacuum tube system, the potable water is heated inside the vacuum tube directly. 

The existence of a thermosiphon makes the hot water to rise which will be again replaced by the colder water. The hot water is collected in the top part of the chamber and pumped through the system. 

Vacuum tube technology is the most efficient heat transfer technology available for the solar system on the market today. A hollow copper tube is inserted through the tube. This specially designed tube contains a small amount of special liquid working like a heat transfer medium. The hollow chamber is created under the vacuum conditions causing the fluid to vaporize at lower temperatures. 

The vapor goes to the top of condenser bulb where it is again cooled back to liquid. Copper heat piping technology is used to absorb and transfer heat very efficiently without losing any energy virtually. The latest technology allows the energy to transfer to the water heating system indirectly. 

This technology is commonly used in systems featuring a heat exchanger like a close loop system. Any water heating system designed for freezing conditions require using heat pipes like antifreeze should be used and the water requires to be separated from the heating system through a solar heat exchanger. Heat piping system is more efficient than open vacuum tubes; but is available with a significantly higher price along with additional copper materials.

Considering Solar Water Tanks for Residential Purposes

Image
Most businesses and homeowners are focused more on adopting sustainability and renewable energy. Among them, solar water tanks are the significant features of solar water heating systems that address energy consumption and provide an eco-friendly way to heat and store water. Please check out this blog and know how these tanks make a positive impact on residential applications:   Understanding Solar Water Tanks – Solar water tanks are innovatively engineered systems that use solar energy to heat and store water. Solar collectors remain at the core of this technology and are typically installed on rooftops or other suitable locations to capture sunlight.  These collectors transfer the solar energy to a heat exchanger or coil within the water tank. When the water gets heated, it will be stored for different residential purposes, ranging from bathing and cleaning to heating indoor spaces. Taking Advantage of Energy Efficiency and Cost Savings – The main reason why homeowne...

How Do On Grid Solar PV Kits Work?

Image
The DC electricity generates Solar Photovoltaic or PV from the sun. Certain materials exhibiting a property known as photoelectric occur at the atomic level.  This is the same principle on which the solar photons get absorbed by a semiconductor material which causes releasing negative electrons. The two charged layers are involved, i.e., the positive layer and the negative layers. The electrons in the negative layer release and flow to the positive layer. When the sun intensifies, this flow becomes more rapid, and the current will be much stronger. The photocell semiconductor layers are made from silica wafers charged positively by a particular material coat. The front part of the cell contains the negatively charged layer and is coated in phosphorous, and the positive layer is in the back covered in boron. The sun hits the negative layer, which frees the electrons. The released electrons get absorbed by the positive layer. A metal coating separates both layers so that we can direc...
