SolarStand ST.I.33 In-Roof System – in brief

Assembly and installation of our SolarStand in-roof system is easy and straightforward. You don’t need any special tools. Additionally, the entire system comes complete with just 10 different components. Even screws and rivets are already taken into account. An additional advantage, which cannot be disregarded, is the use of an insertion rail which is laid on the respective module type. This insertion rail ensures that the module is laid quickly and, at the same time, protected from all loads arising from dilatations.

In terms of tools, you only need a cordless screwdriver with a TX40 attachment and 6 mm Allen, an Allen key with 3 mm and 4 mm, a hand riveter with a 1.5 – 3 mm mandrel, a tape measure and a rule.

In the following, we describe the six steps required to install a photovoltaic installation onto the base of the SolarStand ST.I.33 in-roof system. We also give you access to three demonstrative installation videos which make the process even easier.

Step 1: Eaves linkage

Firstly, the fitter, or solar installer, affixes the eaves linkage in preparation for the assembly.

Step 2: Vertical drainage

Second, the vertical drainage is installed. Screw the vertical drainage profiles in the subsequent grids of the solar module onto the battens. Clamp mountings are then mounted as fix and sliding points. The fix points are then riveted with two blind rivets (see installation video 1).

Step 3: Installing the cross connector

The cross connector is now installed. Slide the sliding block into the channel provided. At the same time, press the EPDM rubber seal into the profile. Ensure that the horizontal drainage rails rest on the EPDM rubber seals across their entire length (see installation video 2).

Step 4: Horizontal drainage profiles and insertion rails

In the fourth step, initially lay the horizontal drainage rails and insertion rails on the EPDM rubber seals. The rails are customised to the module dimensions. Drainage profiles and insertion rails can now be simply clicked into the cross connector. At the ends of the insertion rails, screw in the end angles which stop the PV modules moving apart over time (see installation video 3).

Step 5: Cables and module field connections

Der fünfte Schritt dient der Verkabelung der Fotovoltaikanlage. Verlegen Sie dazu die Stringkabel der einzelnen Solarmodule sorgfältig unter dem Indach-System und nutzen Sie Kabelbinder, um die Kabel zu fixieren. Achten Sie darauf, für die Befestigung ausschliesslich UV-beständiges Material zu verwenden. Dieser Schritt kann auch als Schritt 2 erfolgen, bevor die vertikale Entwässerungsschiene auf der Lattung fixiert wird. Je nachdem, wie Sie Ihre Verkabelung verlegen möchten.

Step 6: Insert and connect the solar modules, and then attach the edge connections

In the sixth and final step, the solar modules can be laid into the in-roof system and connected. Install the individual modules into the profile on the upper side, attach at the bottom, and then slide downwards.

To make the cabling easier, place the module for a short time in the respective lower horizontal profile. This makes connecting the cable much easier. Once connected, the solar module can then be slid in as described above.

Finally, the remaining module fields (verge, roof ridge) are attached to the roof by a fitter or solar installer. Depending on the type of installation, joining plates are manufactured and installed by a specialist.

Please note:

Ensure that roof works are only carried out by trained specialists. All building regulations and the provisions of standards, environmental protection and recycling must therefore be observed and complied with.

Additionally, ensure that during each phase of work at least two persons are present so that in the event of an accident, assistance can be quickly provided. Throughout the installation it should be ensured that both an up-to-date version of the assembly instructions and the project report created for the photovoltaic installation are readily available.
