Solar thermal is a fantastic means of renewable energy generation that allows us to take full advantage of the sun's energy as a means to heat you household hot water supply. Solar thermal panels are most commonly used for heating water and the general living space.
Similar to solar PV(Photo Voltaic) panels, solar thermal is modern sustainable energy source; and it’s a great way to heat your home for those that are financially and environmentally conscious.
There are 3 main types of solar thermal collectors:
Low collectors- These are flat plates that can be used to heat areas like swimming pools.
Medium collectors- Again these are flat plates but are used to heat both water and air.
High collectors- High collectors use a combination of reflective materials, coupled with mirrors and lenses. It then collects the sunlight and turns it into standard electricity.
How to install the collectors
The panels are particularly light weight and are relatively easy to assemble. The panels require very little alteration to the existing wiring in the house. The largest requirement is space and the panels require a few hundred square feet to reach their full potential.
Ok then so what do I actually need?
2. Storage tank
3. Expansion tank
4. Solar station with pump
6. Solar fluid
7. Mounting hardware and
How does this process work?
The solar collectors, along with all the piping/tubes that carry the fluid (usually oil or water) are all placed on top of the roof. The idea is the sun heats the tubes and the fluid.
The controller unit then screens the system's temperature. Once the fluid has reached a suitable temperature, the solar station's pump pushes the fluid from inside the collector into the hot water tank. The fluid then flows through a coiled pipe inside the water tank heating up the water inside the tank.
After it is heated the water in the tank can be used straight away for household needs. Once the water is heated, the fluid will be pumped back up to the collector to be re-heated by the sun. In order to take full advantage of the solar roof collector’s potential, it is best to place it on a place it on a south facing surface, and have it tilted 45 degrees towards the sun.
