Page 4: A Safety Instructions
Safety instructions Please read all safety instructions and information carefully! The Suntub® is intended for mounting SolarWorld Sunmodules on flat roofs only. Other uses are considered unsafe. Observe local ordinances, building standards and accident prevention regulations during installation. Any safety information and/or requirements for other system components must also be followed. -

(28°) and the minimum angle of insolation at your location. Safety information for the edge areas The Suntub may not be installed within the edge or corner areas of the roof. These areas are subject to air turbulence and considerably elevated wind loads (see EC1, Wind loads). - Page 6 Assembly General safety instructions Ensure that any work on the PV system (installation, commissioning, maintenance, repair, etc.) is performed by qualified professionals. Observe all local and national code requirements for the prevention of accidents, including those that may supersede this installation guide. Ensure that fall protection is used on buildings that are greater than 3 m tall.
- Page 7 System assembly overview The Suntub® Assembly System for flat-pitched roofs is a support structure for the lengthwise installation of PV modules. It consists of a black plastic body (100% recycled HDPE) with aluminium and stainless steel mount- ed parts. The excellent ventilation of the modules optimizes the output of the PV system. The ballast required to secure the unit against wind loads is provided by the customer in the form of gravel or concrete slabs, etc.

Dimensions Fig. B1.1 Area approx. 2. m Weighted area approx. 1.30 m (contact surface for concrete blocks, gravel, etc.) Required ballast load In order to ensure the stability of the PV system against lifting, tipping and displacement, it must be weighted down with ballast (gravel, concrete slabs, etc.). - Page 9 The loads can be reduced for interior areas (“Centre ballast” column). 3. The edge area of the roof should be kept clear (spacing 0.2×h). Check with SolarWorld AG before installing within this area. . These tables serve to determine the required ballast loads for the Suntub® Assembly System only.

Page 11: C1 Setup
1. Positioning the Suntub® Assembly System The plastic body of the Suntub® consists of 2 parts which are fitted together (Fig. B1). Position the Suntub® with the flat surface facing south so that the modules are tilted to face the incoming sunlight. - Page 12 2. Ballast After positioning and (optional) connecting, the Suntubs® are now weighted down with the required ballasted loads according to the system plan. Gravel or concrete blocks may be used, for example. The ballast must be distributed evenly. Fig. C1.2 3.
- Page 13 Next, the top clamping connections can be Fig. C1. installed. After the module has been aligned, all bolts can be tightened (tightening torque 20Nm). The modules must be centered on the Suntub®. The distance between the modules when fully assembled should be at least 8mm.

Page 14: C2 Module Connection
Module connection Attention: Connecting modules in series may yield high voltages! 1. Wire the modules according to the wiring diagram. Make sure to strictly observe the wiring diagram instructions (string distribution, electrical switches, group cable). Incorrect wiring may damage or destroy the grid connected inverter and/or the modules. In order to keep inductive coupling as low as possible in the event of a lightning strike, the supply and return cables (+/-) of the string shall be laid as closely to each other as possible (avoid loops) The minimum bending radii of cables (5x cable diameter) must be observed in all situations. -
Page 15: C3 Grounding
The warranty period is based solely on the usability of the Suntub® itself, and only on that component; no liability is accepted for loss of yield or for assembly and disassembly costs in case of damage. - Page 16 16F Yeoksam-dong, Gangnam-gu Seoul, 135 - 925 South Korea SolarWorld AG Martin-Luther-King-Str. 24 53175 Bonn Germany Telephone: +49 - 228 - 55920 - 0 Fax: +49 - 228 - 55920 - 99 service@solarworld.de SolarWorld.
