Solar Hot Water System
A Solar hot water system uses solar panels, to absorb the heat from solar radiation to provide hot water. The solar panel array, can consist of either ‘evacuated tubes’ or ‘flat plate’ panels. The size of solar panels required is project specific, however a typical domestic solar hot water system for a 5 person household is: 30 Evacuated Tubes & 300l Cylinder or 2 x Flat Plate Panels & 300l Cylinder
A solar hot water system is mainly composed of a solar hot water cylinder and solar panels. It works by pumping fluid from the hot water cylinder to the solar panels, where it is heated, and then returns to the hot water cylinder, thus heating your water.
The solar hot water system, also known as a solar thermal system, has a thermal controller installed to ensure the system does not overheat during peak periods of sunshine, and antifreeze is added to ensure it does not freeze during cold spells.
Solar technology can be used to provide approx 60% of your hot water requirements (i.e. showers, taps, etc..), when installed in a South facing direction. The solar panels will provide hot water in the summer, and will pre-heat the water in the winter time, thus reducing the load on your boiler, and your use of the emersion heater.

NuTech Renewables Ltd offer a full solar sizing service, when trying to satisfy Building Regulations (Part L in Ireland) and grant requirements. All of the solar hot water systems are designed, installed and commissioned to be self sufficient, and as maintenance free as possible.
Solar Panels can also be used to heat the water in the central heating system of your home (know as space heating). In new build houses in Ireland solar panels are being used to provide both hot water and space heating, reducing future fuel bills, and improving the BER certificate rating of the house.
NuTech Renewables Ltd also specialise in low energy heating through use of solar panels, and the patented Solar Enhanced Ventilation System. (Please click here for further details

Which solar panel should you use?
Evacuated tube collectors are glass vacuum tubes mounted in rows, whereby each tube is connected to a manifold containing the solar heat transfer fluid.
Evacuated tubes work in cold, cloudy and windy conditions which are very common in Ireland and Northern Ireland. Evacuated tube solar panels tend to have a higher efficiency per m² than flat plate panels.
A flat plate collector usually consists of a large sheet of metal which contains pipes holing a heating transfer fluid, which is housed in an insulated panel
