3�2�7 Bottom of PV-Array: Lead Flashing, Wedge Plank, Sealing Tape Strip
Figure 12: Bottom gutter
The BISOL BIPV module with Solrif® frame can be mounted either down to the eaves or with tile roofing between PV array and
eaves. Observe the tech note about the application limits (snow loads) in the instruction sheet under customer login at www.
ernstschweizer.ch.
When tile roofing is used between PV array and eaves, the transition should be executed using lead flashing and wedge plank.
3�2�7�1 Lead Flashing
For the transition from the bottom edge of the array to the tiles, lead flashing is used as is customary for other roof inserts, for
example skylights (lead foil roll 300 mm or black aluminium Mage Flex flashing tape.
280 mm or 450 mm available as accessories, roll length 5 m or 7.5 m). The required height of the lead flash ing depends on the
roof slope and the tile arch and must be determined in combination with the height of the wedge plank, see Chapter
„Wedge
Plank“.
Notice
If the lead flashing is to be comprised of several sections of Mage Flex flashing tape, the sections must
overlap by at least 100 mm.
3�2�7�2 Wedge Plank
The wedge plank is mounted underneath the bottom Solrif® batten. It supports the lead flashing, ensuring that no trough forms
in the lead flashing and thus no water can remain there.
