THE PROFEIONAL PV MONTING YTEM Installation guide unbeam Nova niversal Page 4-5: : installation of a unbeam niversal system (solar panels facing south). ymmetrical Page 6-7: installation of a unbeam ymmetrical system ( east-west configuration). This installation guide describes the installation of unbeam Nova systems for mounting solar modules on flat roofs. Installation always needs to be based on a configuration and ballast plan generated by the unbeam Calculator software. Please keep a copy of the configuration and ballast plan and this installation guide with your project documentation. If you have any questions about the installation, please contact unbeam BV (for contact details see last page).
Main parts Base units The base units support the system. They are available in several lengths, enabling you to vary the distance between the rows. base unit M (with connector ) base unit E (without connector ) optional Carriers Attach the carriers to the base units to form a stable triangular base for mounting the solar panels. carrier niversal south-facing carrier ymmetrical east-west Ballast racks and wind plates In addition to carrying ballast and deflecting wind, these planar elements have an important secondary function: they reinforce the system s matrix configuration. ballast rack wind plate Various parts foot end clamp also in black mid clamp also in black clamp screw short screw carriers, ballast racks, wind plates cable clip rubber block for gravel roofs rubber mat

Make sure the delivery is complete. Work accurately and systematically. Don t place heavy pallets directly on the roof. The local load on the roof may become very high. Beware of parts and packaging blowing away in the wind and sharp-edged parts damaging the top layer of the roof. Always observe adequate safety measures, such as placing bannisters along the roof edge (for relevant safety standards see last page). The roofing construction needs to be strong enough to carry the weight of the entire solar energy installation in addition to the regular wind, water and snow loads. The roofing material needs to be in good condition and should be able to withstand the maximum local pressure under the unbeam feet. When required, the maximum pressure can be lowered by placing additional feet under the system. Always ensure proper drainage of water under the system. When obstacles or gravel are blocking the free flow of water the system may be heightened with rubber blocks. When in doubt about any of the above points please consult a structural engineer or roofing expert. Configuration and ballast plan unbeam Calculator Nova Every unbeam project plan includes a configuration and ballast plan (for each individuel array of Project B-0013 Basisgegevens van dit veld veldnaam A sunbeam test 1 x 30 v.13 solar modules), which is prepared using the unbeam Calculator software. This picture shows the positions where ballast racks are needed. The numbers indicate the number of tiles to be placed in the racks. Boxes without numbers represent empty ballast racks used to facilitate installation. gebouwhoogte dakmaten dakbedekking met grind ballast Resultaten stuwdruk aantal modules oppervlak systeem totaalgewicht druk per voet 10 m 30 x 0 m bitumen 1 tegels 8 kg 700 N/m 7 174 m 16, kg/m 83 kg 19 kpa,0 16,0,0 6,0 0 It is possible to use several types of ballast tiles, allowing for a large range of weights.

Adjust the sizing tool by sliding the flanges protruding form the plastic sliders up against the side edges of the solar panels and firmly tightening the screws at the bottom of the slider. If you don t have a solar panel at hand, you can adjust the sizing tool using a measuring tape. 3
1. Placing the feet and the base units niversal M or E M M Attach one foot per base unit by clicking it into place at the end without connector. The holes in the base unit line up with the ribs of the feet. Place the base units on the roof in the order indicated in the configuration and ballast plan. Each row is terminated (at the northern end) with an additional foot. Caution: Do not assemble the base units yet!. Placing the carriers 3 1 1. Insert the connector into the next base unit until it is up against the stop.. Insert the yellow end block into the slit. 3. Push outwards to align the screw holes. Repeat this with the end block at the opposite side. When assembling a niversal system, you must first carefully bend the carrier until it assumes the correct angle. Attach the end blocks to the base units with the short screws. Make sure that the base units are inserted all the way, and that all the holes are aligned properly! 3. Aligning, squaring and placing the ballast racks 4 m < 5 Nm 3 m N 5 m A triangle with sides of 3, 4 and 5 metres always has a square angle. Ensure that the entire system is straight and squared, using tools such as a folding square or a laser, or by drawing a 3-4-5 triangle. Always use the sizing tool to make sure the base units are at the correct distance from each other. Attach the ballast racks using the short screws. Tighten the screws firmly, but take care not to strip the thread. 4
4. Ballast niversal 30 cm 1 cm 1000 N/m 30 cm 15 cm position with ballast (number = number of tiles) Place the ballast. Pavements slabs of 30 cm wide can be placed on top. This is allowed up to a peak pressure of 1000 N/m. Ballast needs to rest stable on top and may not cover the bottom of the ballast plate. The use of gravel as ballasting material is not allowed. The small black squares without a number indicate positions with empty ballast plates. These are used to ensure a higher system connectivity. 5. Placing solar panels When placing a solar panel, pay attention to the lip at the end of the carrier, which prevents the solar panels from falling down between the carriers. unbeam Nova end clamps can be used universally for panels ranging from 30 to 50 mm in thickness. Fit the clamps using the long clamp screws. The mid clamps ensure a 10 mm gap between the panels. Fit them with the long clamp screws as well. 6. Finishing < 5 Nm Tie cables running between panels with the cable clips. Additional cable clips can be ordered separately. Mount the wind plates at the backside of the carriers. Wind plates may overlap. Fix them in place with the short screws. The small hole above the central rib in the foot can be used for grounding the system or for attaching cable conduits. 5
