RENOLIT ALKORSOLAR: The only 5-in-1 solution for securing solar panels

5 significant reasons for choosing RENOLIT ALKORSOLAR for flat and pitched roofs

Wind removed solar panels, damaged waterproofing, penetrating moisture and increased weight due to ballast. Just some of the adverse effects of poorly fitted solar panels. As specifier, roofing contractor or installer of solar panels you would not wish to see damage claims of this kind.

Independent wind tunnel tests and controls make it abundantly clear: with RENOLIT ALKORSOLAR you opt for safety and quality!

RENOLIT provides a wind-proof and totally watertight solution.
Many architects, solar installers and roofing contractors are already convinced.

5 significant reasons for choosing RENOLIT ALKORSOLAR

1. Lightweight but very strong.

100% secure, hot-air welded fixing system and no additional ballast.

For an architect it is important that the load-bearing capacity of a roof is not compromised. The addition of solar panels may bring problems. Many PV systems are weighted with ballast to prevent movement. The addition of ballast, for example 80 to 100 kg per m², can prove harmful to a roof structure and lead to serious complications and unexpected problems.

With RENOLIT ALKORSOLAR this problem does not occur. The synthetic profiles together with aluminium box section are very light. Extra ballast is unnecessary since the PVC-P profiles are fused homogeneously with the roofing membrane thanks to hot air welding. This lightweight system is held securely in place and is 100% safe, even in extreme weather conditions.
RENOLIT ALKORSOLAR profiles distribute the extra weight of the PV system over the roof surface. There is no risk of point loading, damage to the waterpoofing and insulation is therefore excluded.

Tested at wind speeds of up to 200 km/h
RENOLIT ALKORSOLAR is technically proven in every aspect. During development, wind tunnel tests were undertaken at the Von Karman Institute (VKI) and tested up to a maximum of 200 km/h (laminar). RENOLIT ALKORSOLAR profiles withstood the tests without any problems.
In addition to wind tunnel tests, RENOLIT ALKORSOLAR has French technical approval (Avis Technique) and German DIBT approval. RENOLIT ALKORSOLAR is unique, being the first and only PV mounting system on the German market with DIBT approval.

2. Fully watertight.

Installation of solar panels on synthetic roofs without perforating the waterproofing.

At its height, the solar market was swamped by all kinds of inappropriate solutions for securing solar panels to roofs. With all the associated dangers. Poor installation of solar panels is often the cause of damage and subsequent leaks.
The method by which solar panels are secured to a roof is therefore key. With the innovative RENOLIT ALKORSOLAR system safety is assured, and the roofing membrane will not be perforated.
Result: no risk of leaks, no additional costs or damage claims!

3. Quick and easy to install.

Simple installation and suitable for all types of PV and solar thermal systems.

RENOLIT ALKORSOLAR is specially designed for quick and easy installation. The synthetic profiles are thermally fused to RENOLIT membranes and subsequently form the basis on which the multifunctional mounting profiles and finally the solar panels are secured. This is regardless of whether the panels are parallel to the roof surface or at a pitch by means of aluminium triangles. Photovoltaic elements are not directly fixed down to the roof structure, which saves a lot of time.

Hot air welding
Hot air welding of these synthetic profiles can be carried out very quickly. RENOLIT has developed a special RENOLIT ALKORSOLAR conversion kit for this purpose which may be attached on an automatic welding device. Providing a useful tool for the professional roofing contractor and making for a particular easy installation.

Minimum wind load
Photovoltaic elements are generally only fitted to the centre section of a roof. The corner and edge areas are not suitable because of excessive wind load. Edge areas will only be considered if the location and height of a building meets the required standard.
In addition, the type of roof deck and façade structure are crucial. The zoning and the distance between the RENOLIT ALKORSOLAR profiles are determined by means of a wind load calculation.

Maximum efficiency
For the output of PV panels the orientation of the building is very important. Try to avoid cast shadow of air conditioning units, skylights or even surrounding buildings because lengthy shadows can be very detrimental to the performance of the solar system. The direction of the actual PV panels is also important. It is preferable to orientate crystalline panels to the south for greatest efficiency and installed at an optimum inclination.
Depending on the orientation, slope and size of the panels a minimum spacing must be maintained. This way, cast shadow cannot substantially diminish the efficiency of the panels.
Generally as a spacing 3x the height of the photovoltaic elements is used. For reasons of maintenance, it is good practise to keep clearance around skylights and air conditioning units.

4. Easy to maintain.

All elements are easily accessible for maintenance.

The RENOLIT ALKORSOLAR system stands out on account of its simplicity and reliability. If maintenance or repair work does need to be carried out, all elements of the system are easily accessible.

Once or twice a year a maintenance check on the roof is required. Installed solar panels should not hamper this work.
Thanks to the simple RENOLIT system, dirt that has built up on crystalline panels on an angle can easily be removed.
A RENOLIT ALKORBRIGHT membrane under the solar installation will provide additional benefit. Grime will not stick so readily on account of the special coating and will be washed away in the rain.
If solar panels need to be replaced, this is possible with the RENOLIT system without the risk of damaging the waterproofing membrane. A major advantage for a PV installer as it is important for a repair to be carried out quickly and efficiently.

5. Surprisingly versatile.

Suitable for new or existing roofs with PVC-P or EVA roofing membranes, for bonded and mechanically fastened systems and ideal as a carrier system for securing façade materials such as wood or aluminium, ... on the roof.

The RENOLIT ALKORSOLAR solution for installing solar panels or solar thermal is innovative, with a wide area of application.
The system can be installed on most synthetic roofs, PVC-P and EVA. RENOLIT ALKORSOLAR profiles can be fitted on new build and just as easily to an existing roofing membrane. Provided, of course, that the existing waterproofing membrane is still in good condition!

The ingenious features of RENOLIT ALKORSOLAR profiles are also evident in new alternative applications for the finishing of buildings. The lightweight profiles may also be used as a carrier profile for securing cedar shingles, aluminium composite sheets, timber planking or even trellising for vegetation. Numerous beautiful aesthetic ideas demonstrate the creative possibilities.
