ATAG iSOL Solar Collector
The ATAG iSol solar flat panel range is the most efficient in the UK and due to our engineering and design technology, they will even perform on cloudy days. Also they are Solar Keymark approved meaning they’ll qualify for any government grants or payback initiatives that may be available.
Solar thermal is one of the more effective and efficient renewable energy sources and can provide you with an abundance of free hot water.
With the UK classified as a temperate climate, we actually receive around 65% of the amount of solar radiation that is received in southern Spain.
Heating a tank of stored hot water accounts for roughly 60% of our annual hot water bills* so it makes sense to capture this free energy from the sun, both from an environmental and financial perspective. *Energy Saving Trust
The ATAG iSol range of solar flat panels are installed with minimum disruption, are high performing, low maintenance, extremely robust and come with a 10-year warranty.
Completing the ATAG iSol range is our pumping station and easy to use intelligent controls. If installed with an ATAG iS or iR boiler and iSteel twin coil hot water cylinder, you will have a super-efficient and extremely reliable solar thermal installation.
What’s more you will have significantly reduced your carbon footprint as well.

ATAG’s iSol fixing kits ensure the iSol collectors can be swiftly and neatly installed into the roof. With the tiles taken away from a section of the roof, the in–roof kit enables the solar collectors to blend into the roof line and can be installed in a portrait position Able to sit above the roof tiles by using special on-roof solar collector brackets, ATAG ensures minimal disturbance to roof tiles. The flat roof ‘A’ frame gives you the option of a solar thermal system where a pitched roof is not suitable or available, but a flat roof location is.
