4. Connect the individual flashings with a join capping piece profile (cf. Image 3-13, p. 17).

TIP
Warmth emitted from the photovoltaic modules lessens the system’s output. Sufficient ventilation of the modules
minimizes the output loss.
High module temperatures lessen the system’s output.
Ventilation in the counter-batten area reduces module temperature and diverts the warmth up and away.
Do not obstruct the free movement of air between the counter-battens.
Divert the ventilation cross section of the counter-battens across the module array and up and away.
Convert the roof ridge into a ventilating ridge with enough ventilation cross sections.
