Solar Star's Roof Mount Roof Fan is the Ideal Ventilation Solution
Solar Star, the leader in solar powered roof ventilation, brings you the most technologically-advanced, environmentally-friendly, ventilation solution today. Best of all, Solar Star brings you the solutions that cost nothing to operate. Imagine the savings.
It's difficult to say whether it's a bargain or not, when there are no prices mentioned. Made me look into the site though.
pretty sure 20% is always on their site. It was there in November with similar details 'save 20%, but only before 30 Nov'. They're in the vicinity of $300, but all they are is a solar panel and a fan. Surely they are (or could be) made in China for less than $10 each.
Anyway, I don't see this as a bargain.
@scubacoles - the solar concept is valid, as you only want to exhaust when there is sunlight which equals hot roof cavity. Whirlygigs don't operate on still, hot days, and they do operate in cold, southerly wind, winter's days (which is when you don't want them to spin).
is this a bargain? I think its novelty
Once again, not a bargain..
Interesting concept but not a bargain..
Would be interesting to see this merged with the whirlygig wind powered fan things.. so you get venting on windy and still, sunny days.
