Dimension of the visible field
= dimension Y + dimension A
a) a) Determination of dimension A (Bottom flashing batten)
The « C » dimension is the Minimum batten width necessary to avoid
reverse slope on the bottom flashing. It’s possible to use a wider
batten, this will simply raise up the PV field
Example:
Dimension of the photovoltaïc field
PV fi el d centered on rake di recti on
Gutter / eave installation
Step
: Step of the system in rake direction, see table below

NOTE: For adjusting the tiles above the PV field, it may be necessary to increase
dimension A to raise the field (see Annexe 3 on p. 57-58).
