There are a broad range of mounting systems available to suit every roof type and application, so SES will specify and provide the most appropriate solution for each situation.
Penetration fixing systems are most common for long run roofing, however there are also an expanding range of clamp-based solutions available for standing seam roof profiles. Such profiles are concealed clip roofing systems, and are often used on flat pitched roofs, so these clamps are beneficial because they eliminate the need for multiple penetrations to mount solar modules. Although they do add some cost above the basic ‘L-bracket’ method, they are highly recommended as it means the risk of water ingress from penetration fixings is eliminated.
Tilt mounting, as opposed to flush mounting to the roof pitch, is an alternative solution to consider that may be preferable in situations where the roof has a flat pitch. Although it does make the PV modules more prominent visually, using this bracketry to elevating each panel to the optimum tilt will ensure you are realising the full potential energy generation possible. It can also be an option to reverse the panel orientation on a south ward facing roof if the fall is not too steep. Tilt mounting does add some cost, but we can advise on whether the extra generation you stand to achieve justifies the additional installation costs based on software modelling.
Another option to consider might be a ‘Ground Mount’ solution. This is an alternative method that enables a Solar array to be mounted on an Aluminium or Timber frame that is set into the ground and can be located away from the main dwelling. This would be appropriate for those wanting a larger system than the available roof space can allow, or those with plenty of space that would prefer not to have modules on the roof. However, the catch is that there is some additional cost in the hardware for the framing and its construction, and a trench is also required to deliver the generated energy from the source into the home. This is a common solution for those establishing themselves ‘off-grid’ greenfield situation where a larger array is required then most ‘grid-connected’ applications.
In all cases, we ensure that all mounting systems are from a reputable supplier and are supported by certified testing documentation in order to comply with the relevant performance standards.
