How It Works

Enough energy hits the earth from the sun in an hour to provide the energy requirements for the whole human race for a year.
That’s an amazing fact so it’s not hard to see why we love solar thermal as an efficient way to capture all that free energy.

A solar panel absorbs the sunlight and traps the heat behind the glass panels. That heat is transferred to a fluid which is pumped around the panel and returned to transfer its heat via a coil to the water in your hot water cylinder. So when you run your bath all that hot water has been heated for free by the sun.

Your cylinder will have 2 coils, the solar coil in the bottom can heat the whole cylinder whereas the second coil can heat just the top section via heat from a boiler. This means on days when there is not enough light the solar panels will heat the water in the cylinder so far and the boiler will top up the heat to the pre-set temperature on the cylinder stat. On a good sunny day the solar panels will heat the whole cylinder without the need for the boiler to come on therefore in either case saving you money.

The result of this is during the summer months your boiler will hardly be used at all and even in the short days of winter the panels are still working tirelessly to contribute heat into the cylinder meaning your boiler does not have to work to provide all the heat.

In some systems your solar panels can also be used to contribute towards the energy requirement of your heating. There are many different ways of designing a system to do this so give us a call to discuss your requirements.

There are two main types of collectors available:
Flat plate collectors and evacuated tubes. Either of these types will provide you lots of free hot water but there are differences between how they work. You will see on our site we have only listed prices for flat plate collectors as we feel these are the most versatile panel and adapt to most situations.
We can provide evacuated tubes if this is the kind of collector you are after.
