Solar Collector
Evacuated Tube Solar Collectors
Evacuated tube solar collectors are very efficient. The efficiency of the evacuated tube solar collector depends mainly on the angle.
The main part of the evacuated tube solar collectors is a special vacuum tube, in which is being situated water.
The entire design is made on the principle of thermos devices. The vacuum eliminates convection losses and thermal conductivity, reducing the overall collector heat loss to a minimum.
Advantages of using solar collectors
The major advantage of solar collectors - simplicity and relative cheapness of manufacture, ruggedness in operation.
The only important point - please be aware that on a hot sunny day with no parsing water can overheat above the boiling point, so the design must take appropriate precautions.
Other, no less important advantage, is that the collector is able to capture and convert into heat more than 90% has got to him sunlight. Even with light cloud, its efficiency exceeds the efficiency of other types of batteries.

Solar Vacuum Tubes - free energy of the sun!
Solar vacuum tube - the main element of the solar installation. It consists of two tubes, resistance to chemical and thermal loads. The outer surface of the inner tube covered with a layer of selectively absorbing the radiation. This covered tube closed at one end, and the other end attached to the outer tube. In the space between the inner and outer tube creates a vacuum to prevent loss of heat.
Heating and hot water on the basis of solar vacuum collectors
System based on vacuum solar collectors designed for production of hot water temperature, through absorption of solar radiation, converting it into heat, accumulation and transfer to the consumer.
Solar air Heater
There are three main methods of active cooling. First of all, the use of electric compressors, which are now standard cooling device in Europe. Secondly, the use of absorption air conditioners powered by using thermal energy. There is a third possibility for air conditioning - using evaporative cooling. All systems can operate on solar energy.
Solar collector, which heats the air, can serve as a cheap source of heat for drying crops - grains, fruits or vegetables.
Using simple and cheap solar collectors for heating the air used to dry the crop is promising to reduce the huge crop losses in developing countries.
SOLAR THERMAL COLLECTOR
Solar thermal collector is one that uses the sun’s energy to gather heat. A solar thermal collector is a solar collector specifically intended to collect heat. This means that when the collector collects heat, it causes the water in a tank to get hot enough that it boils and turns into vapor.
