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
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
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
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,
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.
