Sahara Collectors

Many people believe that solar collectors only work in the summer; however this type of free energy is available throughout the year. Grant collectors operate not just with direct sunlight, but also diffused sunlight, so they even work on cloudy days.

Features & benefits

Grant Solar Thermal can integrate easily with conventional water heating systems. Installation typically takes a couple of days to complete.

The Grant Solar Thermal range includes a high efficiency flat plate collector, multifunctional controller with LCD display, in-roof, on-roof and flat-roof mounting arrangements, the unique Grant CombiSOL, to integrate solar thermal with combination boilers, and the Grant WinterSOL, that provides a fully heated cylinder of hot water during periods of low thermal gain.

The Grant Sahara collector has a durable aluminium frame with a bronze anodised finish, which has been designed to blend with most domestic roof types. During the manufacturing process, the use of premium materials guarantees the collectors’ reliability and durability. Grant collectors have been tested to the requirement of BS EN 12975 and are certified with the Solar Keymark.

Heat Transfer Technology

Grant use a unique patented system where the heat transfer sheet interlocks both the pipe and absorber for perfect thermal transfer. Additional aluminium plates enclose the copper pipes and combined with an industrial strength adhesive result in 360° heat transfer.

When choosing a solar thermal system, there are a number of factors to consider. Almost any roof type is suitable, however a south facing arrangement could gain 100% of the light available during the day. If the roof was to face South-East or South- West there will be a reduction in yield by 5-10%.


Grant Solar collectors can be quickly and easily located above the roof tiles or slates using brackets and a mounting rail attached directly to the roof trusses. This system is available with fixing brackets suitable for all roof tile types including slates, on roof pitches ranging from 20° to 60°. The on-roof mounting system is supplied as standard with any Grant Solar Kit.


Installation of Grant Solar collectors set into the roof tiles or slates ensures a low-profile appearance. The roof surface beneath is closed within an aluminium weathering cassette incorporating flashings, drainage channels, etc. In new build applications this mounting option reduces roofing costs, as tiles are not required beneath the installation. (Note: for a reclaimed slate roof, the flashing may appear uneven. Please contact Grant for an alternative solution)


The flat-roof system is based upon the on-roof design. The mounting rails are fitted to a rigid inclined frame structure. This method allows the collectors to be positioned quickly and easily on a flat roof
