Solar Powered Soffit Fans LLC (SPSF)

The Original.  Solar Powered Soffit Fans LLC is the manufacturer/designer/inventor of unique solar fans since 2010 and is located in Davie, Broward County, Florida.  We were the first to sell solar soffit fans and solar crawl space fans over the internet. Our solar fans are not mass-produced solar attic fans made overseas and “patriotically” branded and sold in the US at huge markups. We researched, developed, and tested these concepts and have been commercially providing solar powered soffit fans and solar crawl space fans longer than anyone that we know of. Our goal is to provide safe, innovative, efficient, easy to install, low cost home solar ventilation solutions that gradually pay for themselves while improving living conditions. We continuously work to improve the product. Our solar fans have been tested, improved, and re-tested on real houses, under real conditions, with real occupants, and have been proven to reduce cooling costs, to reduce house humidity and moisture damage, and to improve house air quality. We've sold our fans all over the US and Canada, and we have spoken to many of our customers about their specific ventilation needs and problems. If we don’t think we’re the right solution, we’ll say so, rather than just try to sell the products.  We hope that you will like our product, and we welcome your questions, comments, and feedback.   

Tax Incentives

Solar Powered Soffit Fans LLC products qualify for federal tax credits (see link below) and may qualify for state, local, and utility incentives.  


We provide, and honor, a 5 year warranty for our easy-to-install SPSF equipment. (see link below). From 2010 to 2017, we've received and honored a total of 7 warranty claims. Don't be fooled by 25 year and 'lifetime' warranties; the solar panel manufacturers normally don't warrant their products more than 20 years, so how can the solar fan manufacturer? They are counting on customers to not take their fan out of the roof (big hole!), attic, or crawl space!
