The beauty of a solar hot water system is its relative simplicity and durability. It sits in the sun, absorbs the heat, and transfers it to where you need it. There are two types of solar hot water collectors:
- flat plate collector
- evacuated tube solar collector
Flat plate solar collector
Flat plate collectors work on copper pipes running through a glass covered collector, often connected to a water storage tank. The sun heats the copper pipes and the resulting hot water is thermo-syphoned out of storage tank.
Evacuated tube solar collector
Evacuated tube solar collectors use consist two glass tubes fused at the top and bottom. The space between the two tubes is evacuated to form a vacuum. A copper pipe running through the centre of the tube meets a common manifold that is then connected to a slow flow circulation pump that pumps water to a storage tank below, thus heating the water during the day. The hot water can be used at night or the next day due to the insulation of the tank.
The choice between flat plate or evacuated tube solar collectors can sometimes be one of aesthetics. Flat plate systems are more pleasing to the eye. Also, they are not as fragile as the glass tubes and therefore not prone to as many breakages.
At Solar Directa, our flat panel systems encompass all the latest technological innovations and are of the highest quality. A Flat plate system tend to be cheaper than an evacuated tube solar collector because they are a simpler design and easier to manufacture. Our flat panel systems do not require any expensive installation procedures.
