6 FAQs about [Solar cell vent hole blocked]
Will solar panels block a plumbing vent?
Solar panels installed correctly over a plumbing vent won’t block the plumbing vent. If the vent height is reduced to 2-inches above the roof and the panel is installed 5-inches above the roof, the airflow is sufficient for the vent to function to equalize pressure in the system.
Can a vent pipe be hidden under solar panels?
The pipe re-directing the vent can be hidden under the solar panels. This allows for greater coverage of the roof area with solar panels without compromising the building code in your region by shortening the vent pipe.
Can a solar panel cover a plumbing vent?
A solar panel can cover a plumbing vent. Solar panels are generally installed at the height of 5-inches above the roof. Vent pipes can be cut down to a height of 2-inches since the solar panel protects the vent opening from snow and other debris. The 3-inch gap provides sufficient space for airflow.
Can a solar panel vent be shortened?
Leave a gap in the solar panels to accommodate the vent or use a solar roof jack. If your local legislation does not allow for the vent pipe to be shortened to accommodate your solar panel installation, then your options are limited.
Why is my solar panel not working?
Consequently, there is no air moving in or out of the vent pipe that could cause a problem for the solar panel. Likewise, there are no fluids or acidic gasses the pass up the vent pipe that could damage the solar panel or its wiring.
Does a solar panel need a vent pipe?
No high-pressure air or liquids is venting from the pipe that could cause a problem for the solar panel. Plumbing waste systems operate at very low pressures, close to that of normal atmospheric pressure. Consequently, there is no air moving in or out of the vent pipe that could cause a problem for the solar panel.
