1. Alpha – Project steps & common errors

2. Alpha – From planning to the installation
Inspection of building and roof
Filling our the planning aids
Input of project information in MS Quickconfigurator or forwarding of information to Mounting Systems GmbH
Static check
Choice of appropriate configuration
Offer planning, bill of materials and documentation
Placing the order
Forwarding of graphic documentation (construction view) to the installer
After goods receipt, inspection of components according to bill of materials
Installing the system
Stand

3. Overview mounting systems – Planning aids
Checklist for all relevant project information
Data concerning the site
Building data
Configuration of PV system
Attention: Roof construction important! Especially:
Distance of rafters (irregularities?)
Dimension of rafters
Type of roof construction, tiles etc.
Stand

4. Overview mounting systems – Advantages of the „Quickconfigurator“
Input of project description
Determining of building data
Definition of wind and snow load
Module planning
Choice of right components
Construction view
Complete bill of materials
Print of all data and results, including verifiable static

6. Common errors – Generalities
Problem
Consequence
Error prevention
Missing building data
Incorrect combination of material, delay or stop of installation because of necessary reorders
No static verification, no insurance coverage in case of damage
Reduced durability, property damages
Completing of planning aids before generation of bill of materials
Subsequently modified configuration of project
Inspection of project configuration on site (Attention: consider irregular position of rafters next to windows/chimneys etc.)
Installation not according to planning
Delivery of graphic dimensioning generated with the Quickconfigurator to the executive installer
Inappropriate material: roof hooks, fixation material on rafter
In case of an on-site meeting, measure tiles, height of battens, the distance to rafters and dimensions of rafters and calculate the material according to it.
Installation faults
Installation according to planning and manual
Stand

7. Common errors – assembly faults
Fixing the roof hooks:
No planning of shims
Fixing of standard roof hooks with less than 3 screws
No observance of edge distances in the rafter
hook-arm putting pressure on the underlying tile
Excessive rail-cantilever because of non-observance of planning data
Removing roof tiles and cutting them:
No replacement of old, fragile roof tiles below the roof hooks
No or insufficient cutting of tiles, breakage of tiles during cutting
Other installation faults:
Wrong insertion of Quickstones
Loose tightening of bolted connections
Stand

8. Conclusion – Common errors
Error prevention through:
Accurate input of building data, module dimensions etc. (planning aids)
Utilization of the Quickconfigurator
Correct planning information for the executing installer
Check of delivered material prior to installation
Necessary tools and additional material (shims, replacement tiles) on site
Careful and correct installation according to planning and installation manual
Ensuring the correct fixation of all screws
A structured approach will give the installer / end customer the impression of professionalism!
