Solar vs. Electric: Key Differences
Power
Solar fans use their panel during sunlight. Hard-wired fans use household electricity.
Controls
Hard-wired models may offer thermostats or humidistats. Solar models vary by manufacturer and accessory package.
Installation
Solar generally avoids a new branch circuit; both still require a weather-tight roof or gable installation.
Operating Pattern
Solar output follows available sunlight, which often overlaps with peak solar heat gain.
Frequently Asked Questions
Do you inspect before recommending a fan?
Yes. Roof condition, intake ventilation and attic conditions should be reviewed first.
Can a solar fan replace ridge and soffit ventilation?
Usually it should be evaluated as part of the overall system, not assumed to replace properly designed passive intake and exhaust.
Will it lower my electric bill?
There is no universal savings guarantee. Energy use depends on the entire building envelope and HVAC system.
Can Terra Nova install the fan during other roof work?
Yes. Coordinating the work with roof repair or replacement can make flashing and placement easier to evaluate.
