THE DIFFERENCES OF VACUUM TUBE SOLAR ENERGY SYSTEMS FROM SHEET GLASS COLLECTORS

*Our system consists of two pieces of telescopic tube. The heat dissipation is minimum, because there is a vacuum among two tubes. The external glass is resist and against the weather conditions. The internal tube is made of a specific combinated glass, which is transparent and resistant, and covered with a specific surface in black. This selective surface absorbs %93 of sunbeams and turns it into the heat and minimizes the reflection of sunbeams (%7)

*Because there is a vacuum among two tubes, the heat dissipation occurred by transmission and moving is minimized. The heat dissipation inside of the tube is prevented by the vacuum tube during cold, rainy, snowy, and windy times. That's why the system van be run along 12 months.

There is no vacuum in old styled collectors; therefore the heat dissipation is very high. This situation minimizes the productivity and prevents using along the whole year. 

Old styled collectors require antifreeze in case of freezing of water. This kind of systems don't run so good under 0 C.
   

*The metallic component of our system is made of stainless steel(chrome-steel). The water is drinkable.

The old styled solar energy system has some problems like an oxidization, calcification or obstruction. And also the water is not drinkable.

*The 50 mm polyurethane, whose heat transmission coefficient is very slow, is used for the hot water tank isolation in our system.

The fiberglass is generally used for the old styled solar energy system boilers. The heat keeping degree of it is lower than the polyurethanes. 

*Our firms cylinder vacuum tube receives the sunbeams vertically and the reflection minimizes, because it has a special cover. Thus the temperature of water can rise up to 9500 C during summer, 5500 C during winter.

Old styled solar energy systems receive the sunbeams vertically only on midday. And the heat degree is always lower than our new systems.
