“Design is not just what it looks like and feels like. Design is how it works.” –Steve Jobs
When sunlight and infrared rays hit our black porous geotextile collector surface, 94% of the heat is momentarily retained. That captured heat is then pulled through the collector's tiny holes. The heat and fresh air blend and enter the building as warm fresh air, not cold. The overall efficiency of available solar energy converted to desired warm fresh air, is 80%.
How Solar Equipment Screening with Collectors lowers costs and carbon use in RTUs
Solar Equipment Screening and Collectors have very few design limitations. Installations on rooftops or south facing walls function equally. The image above shows a collector and screening sized for an RTU's makeup air and more.
The United States Department of Energy ranked the invention of the transpired solar collector (aka solar ventilation pre-heaters) in the top 2% of all energy related technologies
Sunreps 307 collector technology was originally patented by the National Renewable Energy Laboratory, a division of the Department of Energy
The United States Department of Agriculture certified Sunreps' 307 collector in 2016, thus making the 307 collectors eligible for the Rural Energy for America Program (REAP) for significant grants and loans
Sunreps' collectors are eligible for different State grants, the Federal Investment Tax Credit and MACRS
