Application:
 
Typical roof-mounted solar ventilation fan 
A typical roof-mounted solar attic fan will be effective in removing excessive heat from the attic. 
 
When mounted near the peak the solar fan forces hot air OUT while pulling fresh air IN via eave/soffit vents.
This exchange of air keeps the attic space from overheating.
 
A solar fan is more environmentally friendly.
Though initially the installation may be costlier, in the long term it would turn out to be cheaper 
because it does not use power from the utility grid 
and may provide savings up to 30 percent on air conditioning costs.
