Choosing a fan for the solar heater

 Most home made solar heaters use computer fans to blow air. The panels I have are commercial made. So they are larger than most home made ones I have seen. They are about 3foot by 8 foot. I found the bigger the fan the more heat is pushed thew the panel into the house.I only have 1 panel installed, and vented thew the kitchen window. I need to find a fan that will blow harder to get more heat to circulate thew the house. The fans I choose also need to be cost effective, As in the energy they use needs to be free or low cost. I hope to run the fans on solar electric panels. Either direct wired `12v dc. If I use normal 120v the could be plugged into an inverter and ran on a larger solar panel. So I have some researching to do. I have been looking at Inline Duct Fans, solar attic vent fans. etc. Do not know what to try first.
