Evacuated tubes are the absorber of the solar water heater. They absorb solar energy converting it into heat for use in water heating. Evacuated tubes have already been used for years in Germany, Canada, China and the UK. There are several types of evacuated tubes in use in the solar industry. Diyi collectors use the most common "twin-glass tube". This type of tube is chosen for its reliability, p...

Heat pipes might seem like a new concept, but you are probably using them everyday and don\'t even know it. Laptop computers often using small heat pipes to conduct heat away from the CPU, and air-conditioning system commonly use heat pipes for heat conduction.
The principle behind heat pipe\'s operation is actually very simple.
Structure and Principle
The heat pipe is hollow with the space ins...

Solar water
heater performance is often presented as a graph, or set of
three performance variables. Values may be provided based
on gross area, aperture area or absorber area. In Europe,
aperture or absorber is often used, in the US, gross area
is often used. It doesn\'t really matter whi...

When choosing a solar collector, selecting the
correct size is important. To find out what size collector you need
please contact us. Once you have
determined what size collector suits your needs, the next question
is where to install it.
Deciding the Direction and Angle of Installation
The angle and direction of installation is also ...

What is solar insolation?
The amount of electromagnetic energy (solar radiation) incident
on the surface of the earth. Basically that means how much sunlight
is shining down on us.
Why is knowing the insolation level useful?
By knowing the insolation levels of a particular region we can
determine the size of solar collector that is required...
