Step 2: How do our systems work?
Would you be surprised if somebody told you that solar
panels work effectively in temperatures of 0°C and below? It is a common misconception
that solar systems only convert the Sun’s heat into useable energy, this is simply
not true. The panels are powered by Sun light; this doesn’t have to be direct sunlight!
Even on a cloudy day you can rest assured that our system will produce enough energy
for your hot water.
Solar panels act like a mini power station on your roof.
They collect Sun light which is absorbed by the panel’s specially engineered surface
and convert it into heat. This heats up the heat transfer fluid in the copper heat
transfer pipe to a temperature higher than the water temperature in your hot water
cylinder. When a temperature greater than that in the hot what cylinder is achieved
a digital controller activates a pump which pumps the heat transfer fluid through
the heat transfer pipework in your hot water cylinder and heats up the water. When
there is sufficient hot water in the hot water cylinder the pump stops. If the temperature
in the hot water cylinder drops, or water is drawn off the pump starts again bringing
the water temperature back up to the desired level. We fully expect our systems
to provide up to 70% of your yearly hot water needs. We recognise
that during the winter when days are short our systems will make a smaller contribution
to your hot water than during the summer when days are longer, when our systems
could provide you with up to 93% of your hot water needs.
