How far must photovoltaic panels be located from the roof ridge?

1. 2 feet

2. 3 feet

3. 4 feet

4. 5 feet

The correct answer is: 3 feet

Photovoltaic panels must be positioned at least 3 feet from the roof ridge to ensure adequate space for maintenance and safety. This distance helps to avoid potential safety hazards when firefighters or maintenance personnel need to access the roof, allowing them to navigate around the panels safely. It also helps to maintain the integrity of the roof and supports effective water drainage. Keeping this distance is a crucial consideration in compliance with building and safety codes to ensure protection both for the structure and the individuals who might work on or near it.
