Solar Limpets Advantages

for

Natural/Artificial Slate & 10 x 6 Tile Installations

Traditional Metal Hooks

Solar Limpets

Tile and especially slate installs can be very time consuming. Tile or slate, once trained 3-4 hours for a 4kwp install will be the norm.
On Rosemary type tiles, numerous tile breakages can occur below the roof hooks during and following installation of the PV system. Installing Solar Limpets as per training reduces such breakages by 90 - 100%.
Numerous slate removal required. No slate removals necessary. Not even to find the rafters.
Spare slate required to replace breakages. No Breakages. Even when the Limpet roof hook is stood on!
Slate or tile cutting & notching required. No cutting or notching required.
Spare tiles possibly required. Each Limpet fitted produces 1 -2 spare tiles.
Flashings required. No additional flashings required.
Packing of rafter tops required. Packing not required.
Damage to slates caused by slate ripping etc. No slate removals required.
Battens splitting when ripping original slates out (time consuming to repair!). No slate removal/refitting required.
Not easy to install for a non- experienced roofer and often difficult, even for an experienced roofer. Simple to install correctly for any tradesman.
Cable entry requires special flashing kits or imaginative options. Limpets can be simply adapted to provide a weatherproof 4 & 6mm cable entry, for both slate and tile applications.
Limited/no adjustment to suit varying roof conditions, often causing additional stress to rails/fitted panels. Automatic 360-degree adjustment available.
Loading is placed on individual rafters. To spread this load requires staggering the roof hook fixing positions onto alternate rafters. Fixed into the rafters but over the battens, Limpets automatically spread any vertical loading via the battens to adjacent rafters.
Unsuitable or difficult for:
Foam sprayed or insulated slate roof coverings.
Modern interlocking type tile/slate coverings.
Warm roof type constructions.
Cross battened roofs and roofs where an overlay of insulation has been applied onto the rafters.
No problem to install Solar Limpets.

Health & Safety

Traditional Metal Hooks

Solar Limpets

Possibility of hand and ear injury increased to installer using Slate ripper and lump hammer to remove galvanised and iron slate fixings. Slate removals not required.
Specialist cutting tools required. No tile or slate cutting required.
Dust hazard created by tile and slate cutting (e.g. asbestos dust in old cement fibre type slate). Minimal risk when drilling for slate application. See: HSE Instructions.
Roof access ladders required. Access to the roof with ladders is often difficult, damaging or simply not possible. No ladders required, Limpet base plates can be used to support timber rails during install avoiding damage to slate and tiles.
Removal of array at end of life or for roof works etc will involve major slate replacement and the clipping and strapping of the replacement slates. No slate removal/replacements necessary.
