So, to get a good performance from a solar attic fan it is important to get the high wattage solar panel is a necessary. As the power output from the solar panel will directly affect the performance of the fan. This is main reason at Amtrak Solar we provide the highest wattage solar panels for our fans in this industry.
I’m trying to select a solar powered fan for a solar drying kiln. There seems to be a lot of insufficient and contradictory information in sales claims for a lot of suppliers. I need a fan with a metal (not plastic) blade that will produce about 800 to 1000 cfm. I would like to keep my cost at no more than $250. What would you recommend? BTW, I do happen to be an engineer from the HVAC industry.
