Seams without Flashings
1. Fasten the top row of the modules to the rafters by means of mounting clamps “long” for flashing “top” and test
for stability.
2. Fasten sealing tape (rolled sheet lead or Mage flex strip) to the mounting board.
3. Cover the upper array edge directly with a ridge tile.

Ventilation ridge
TIP
Warmth emitted by the photovoltaic modules lessens the system’s output. Sufficient ventilation of the modules
minimizes this output loss.
High module temperatures lessen the system’s output.
Ventilation in the counter-battens reduces the module temperature and diverts the warmth up and away.
Do not obstruct the circulation of air between the counter-battens with built-in components.
Convert the roof ridge into a roof ridge ventilation system with sufficient cross-ducts.
