Installation Instructions - Roofer

The roofer makes a "roof check" before beginning the work.

Your Roofer will check

That the roof area is large enough to accommodate the planned installation. A 1kWp installation consists of 96 solar roof tiles, arranged in sets of 8 (strings), each string is 12 roof tiles.
That the chosen area is free from shading and shadows.
There is adequate roof ventilation to prevent heat or condensation build up.
The tile manufacturer, type and colour to be replaced, and the availability of the SRT model.
The original roof tiles were properly installed and can be easily removed.
For obstacles such as vents, sky lights or chimneys etc.

note: When obstacles are within the planned installation area they can be easily accommodated with the flexible "string" system

The installation area ideally should face direction south (SW-SE) on a diagonal roof with a 25-35 degree incline.

The "roof check" now complete, your roofer will be able to make a detailed diagram of the existing roof clearly indicating the position of the planned installation. Below are a few helpful pointers for the roofer to complete his diagram.
He must determine the best position for the solar switch box (SSB) inside the roof. This should be as central as possible to the installation area, in an easily accessible area.

Depending on the string arrangement used the roofer can then plan the cable channels to meet at a central point where they will enter the roof, for connection to the solar switch box (SSB).

It is also important to mark out where and in what arrangement your strings will take, mark and number the strings to their corresponding solar switch box connection. This will aid any troubleshooting should a connection problem arise.

The SRT (1kWp) set comes with 2m extension cables, in the event your strings are more than the standard cable distance from the central roof entry point.

Possible or existing special fittings like snow stoppers can be easily integrated.

Assembly by the licensed roofer

The Roofer can now begin


Examine whether the diagram passes the roof in question.
Check the condition of the supplied SRT - sets
The original roof tiles and snow stoppers are now removed and stored for possible later re-use, or disposal.
The center cable inlet where the cables enter the roof to the SSB is now made, this should be approximately a 25mm hole.
The SSB is then securely mounted just below the entry hole. The wiring harness of the solar switch box can now be fed through this hole from the inside out.
Thread the individual numbered string cable pair (consists of 2 cables, red + blue -) from the SSB one after the other and distribute them immediately to the planned string positions and secure them with insulating tape.
Always lay all cables under or beside the roof frame, this can help prevent damage or a deformation of the cable insulation.
When all string cables are in position and secure you may start laying the roof tiles. Begin with the first string, connect the 12 SRT together and the string cables according to the diagram below. Fix the SRT in place using screws or nails.

Note: Each string produces a harmless safety voltage so long as the SSB remains sealed and is not connected to the inverter.
The connectors used in this system have a simple closing and opening mechanism.
Closing- take the two cables by the housing and push together until you hear a definite "click". Check they are firmly connected by gently pulling on both cables.
Re-opening- to open the connected cables it is important that you take hold and pinch the housing on the inner (white) connector, and the cable (not the housing) of the opposite connector. Pull them firmly apart. Note: make sure the installation is fully disconnected from the inverter and the grid before re-opening.

Test the string immediately. If the string is properly connected the corresponding red indication lamp in the SSB will light up.
Repeat this process for all remaining strings.
When all red lamps are lit and all SRT are fixed, you can be certain the installation is properly installed and working.
Snow stoppers, when used, can now be reinstalled.
Finished! - lightning protection or extra metalworking is not necessary with this type of installation.


What's Next?

The electrical installation may take place at any time of your choosing. The coordination between the roofer and the electrician is no longer necessary, as is the case with a conventional panel installation.

Maintaining your SRT installation

You should make regular checks on your SRT system. They include:

      Check your SSB and make sure all lamps are on.
      Make sure your roof is free from dirt and debris.

Should the dirt build up reduce the units efficiency, you may clean the SRT units. Take care,
do not use chemical detergents or pressure cleaners.
We recommend soapy water with soft cleaning utensils, to prevent damage to the sealing compound.

Important! Be sure your roofer leaves a copy of the installation plan with you, it is an integral part of your installation.

Safety information

Only the licensed roofer is allowed to perform the installation. He knows the dangers involved working on the roof and will take all the necessary precautions.
Climbing on the roof is dangerous for the unqualified and may result in serious injury or death.
The roofer is allowed to connect the SRT's and the SSB. So long the SSB remains sealed and not connected to the inverter, the voltage produced is a low harmless safety voltage.
Only the licensed electrician is allowed to open the SSB. When the SSB is connected to the inverter, the voltage produced can be dangerous.

Don't forget

Mount your supplied plaque on an external wall, informing the public of your proud contribution towards a clean environment.
