Page 20: Installing Arres
6. Installing ARRES 3.0 PREPARATORY WORK – NEW ROOF Lay a watertight sarking membrane over the rafters. Observe the applicable national standards. This prevents any condensate water or precipita- tion that penetrates during a storm from damaging the roof structure.
Page 21 6. Installing ARRES 3.0 Screw the module battens to the counter battens according to the PV system plan. If necessary, level the module battens. Straight module battens of the same height make the work easier and ensure that the PV system is watertight. The module battens should be 100x40 mm in size for the easiest instal- lation.
Page 22 6. Installing ARRES 3.0 Use perforated flashing to close the gap between the cross battens and roof surface to prevent ro- dents or nesting birds from damaging the PV sys- tem or the roof. Fit the perforated flashing flush with the end of the cross battens at the sides to avoid any impairment of the water drainage along the gable ends.
Page 23: Grounding Concept
6. Installing ARRES 3.0 GROUNDING CONCEPT Screw the grounding bridge into the hole marked by the grounding symbol sticker on the back of the module using the screw supplied. Then connect the base profiles electrically to the equipotential bonding system for the building. Ad- here to the specifications given in the current ver- sion of the NIN when doing this.
Page 24 6. Installing ARRES 3.0 INSTALLING THE ARRES 3.0 PV SYSTEM Now install the base rail together with the lower edge trim along the eaves. Ensure that the base rail is aligned perfectly hori- zontally. Screw it through the flashing for the lower edge trim and fasten it to the lowest module batten using the supplied screws.
Page 25 6. Installing ARRES 3.0 During installation, always check that the perforat- ed roof connection profile is correctly seated in the module frame. For this purpose, the profile is pushed upwards in the counterpart of the upper frame profile as far as it will go in the direction of the ridge.
Page 26 6. Installing ARRES 3.0 Start the installation of the second row from the left side again. Slide the module into the slot on the roof connection profile for the module below. Install all modules and dummy modules one after another in the same manner until reaching the up- per right edge of the PV system.
Page 27 6. Installing ARRES 3.0 Dimension the upper apron flashing according to the roof characteristics so that the cleats can ac- commodate the ridge hooks and the perforated flashing. Slot the apron flashing onto the ridge hooks and screw it together with the perforated flashing to the prepared cross battens.
Page 28 Alternatively, standard flashings from Solarmarkt GmbH can be used to provide flashing around the PV system, for example for tiled roofs. The installa- tion is the same as for the existing Arres PV system and is described in the associated installation in- structions.
Page 29: Installing The Arres Snow Guard
7. Installing the Arres snow guard Before installing the snow guard dummy modules on the roof, attach three brackets to each pre- drilled snow guard dummy module. Use the supplied nuts and bolts for this. Tighten these to a torque of approximately 25-30 Nm.
Page 30 7. Installing the Arres snow guard Install the snow guard pipes by sliding them side- ways through the holes in the brackets. Ensure a flush connection between the snow guard pipes and the snow guard dummy module. To extend the snow guard pipes, connect them with the snow guard pipe connectors supplied.
Page 31 SIA 261. No Arres windows may be installed directly above the snow guard. If very heavy snow loads require an additional snow guard in the middle of the module array, then further rows of snow guard dummy modules can be seam- lessly integrated into the PV system.
Page 32 7. Installing the Arres snow guard ICE SHEET HOLDERS – SNOW STOP SYSTEM Install the optional ice sheet holders where re- quired. These prevent ice sheets from sliding down in the spring and slipping between the snow guard supports. For optimum protection, it is recom- mended to install 6 across the entire width of each module.
Page 33: Removing Individual Modules
8. Removing individual modules You do not require any special tools for replacing a module in the middle of the array. However, it might be recommended to use glass suction clamps in certain cases. Make sure that you do not walk on the module sur- faces.
Page 34 8. Removing individual modules Then pull the module downwards and lift it far enough so that you can support it against the roof, e.g. with wooden chocks. Proceed in the same manner with the remaining modules around the module being replaced. Now slide the module to be replaced upwards and lift it steeply to disengage it from the upper slot.
Page 35: Maintenance
9. Maintenance Arres 3.0 ONGOING INSPECTIONS AND CARE • The PV system must be serviced every year. • Check the connecting cables and plug connec- tions for corrosion and mechanical integrity dur- ing the annual inspection. • Check the condition of the mounting system.
