4 FAQs about [Photovoltaic panel roof ventilation requirements]

What are NHBC standards for roof-integrated solar panels?

The updated NHBC standards support the practical requirement to integrate solar panels into roof systems, while maintaining optimal moisture management and energy efficiency. With clear guidance on ventilation, contractors can install roof-integrated solar panels without compromising roof integrity or performance.

Do solar panels need a roof ventilation system?

For many integrated solar PV panels, the NHBC advises that traditional roof ventilation strategies, such as ridges, eaves and tile ventilation, are generally sufficient to maintain airflow and manage moisture, without requiring additional counter battens. New ventilation guidelines

Do solar panels need to be ventilated?

In January 2024, the National Housebuilding Council (NHBC) updated its 7.2.15 standard, covering ventilation, vapour control and insulation in pitched roofs. This update aimed to provide improved clarity about how roof-integrated solar panels, such as the Marley SolarTile®, should be ventilated.

Can a solar panel be installed on a roof?

In other words, if an in-roof solar panel is installed, the whole roof should be considered impermeable and other roof ventilation options, such as ridge ventilation, eaves ventilation and tile ventilation, should be used to ensure sufficient airflow and effective moisture control.
