GASOKOL Solar Thermal Panels from Barres


What are Solar Thermal Panels?
Solar thermal (ST) panels use UV solar power to heat water. They can be mounted on-roof or as part of the roof and like PV panels they work best when south facing.

Why should I use Solar Thermal Panels?
Solar thermal will save you energy, provide hot water, and reduce CO2 emissions. They will also provide you will an annual payment under the governments Renewable Heat Incentive (RHI) scheme.

What do I need in order to install Solar Thermal Panels?
Ideally you will need a good condition un-shaded roof with adequate space, facing in a southerly direction. The panels can also be mounted on the ground using frames.

How much energy can be generated by Solar Thermal Panels?
The energy generated varies depending on your location, how much space you have for panels and whether you have any shading issues.

The system diagram shown above shows a typical installation for a two panel system. The chart on the left shows the output provided by the solar panels if installed in the Inverness area.

The chart shows how much the solar panels would contribute to the domestic hot water production per month. More panels will contribute more, but it is important that the system is properly designed, in particular that the tank be matched to the number of panels.
