FAQ
Q: What are the advantages of Evacuated Tube Solar Collectors over Flat Plate Collectors?
A: Evacuated Tube and Flat Plate Solar Collector products are both of very high standard and offer superior performance. There are many different arguments about which type of collector is better. Our research has shown that evacuated tube collectors provide a more constant output throughout the year, and are frost resistant. The life expectancy is also longer on the evacuated tube collectors. Flat plate collectors are slightly cheaper, however, and if installed with the correct controller system, frost is not a problem. Our conclusion is therefore: Installing a flat plate collector is good, installing an evacuated tube collector is better.
Q: Will a solar hot water heating system work on a cloudy day?
A: Yes. Although the heat output of the solar collector is reduced on overcast days, it will still be able to provide heating. Approximately 20-25% of the sun’s energy penetrates the clouds and is usable.
Q: Can I use a solar hot water heating system with my existing hot water system?
A: Yes. There is a special conversion valve to change your normal geyser into a solar geyser.
Q: How long will it take to install a system?
A: On average it takes less than a day to install a complete solar thermal system.
Q: How does a solar thermal system work?
A: A solar thermal system consists of a number of components – a solar collector, a pump, a controller and a hot water storage tank.
Q: What is the life expectancy of a solar thermal system?
A: The life expectancy of our systems is more than 25 years.
Q: How much maintenance and service is required?
A: Our solar technology requires virtually no maintenance of the system except for occasionally wiping the collector’s surface if it has collected dust. We do, however, recommend that the system be checked annually to ensure that you are getting the best possible efficiency out of the system.
Q: What happens if an evacuated tube collector is broken?
A: On our Evacuated Tube Heat Pipe Solar Collectors, the system will remain operational, however the efficiency of the system will be reduced slightly. Replacing a broken glass tube is a very simple and inexpensive operation.
