A complete solar roof system consists of two types of elements: active and inactive.
Active Elements
- Contain integrated photovoltaic cells
- Generate electrical power from sunlight
- Connected to the electrical system
- Produce the solar energy output
Inactive Elements
- Non-PV roof elements matching the active tiles or sheets
- Provide complete roof coverage
- Maintain consistent aesthetics
- Ensure weatherproofing across the entire roof
Why Both Are Necessary
- Complete Coverage: Not every part of a roof can accommodate solar cells. Inactive elements fill these areas.
- Aesthetics: A roof with only scattered active elements would look incomplete. Inactive elements create visual continuity.
- Functionality: Inactive elements provide structural support and weatherproofing where solar cells are not needed.
- System Integration: Together, active and inactive elements form a complete, unified roof system.
The ratio of active to inactive elements depends on your roof shape, orientation, and solar capacity goals.
