3M Solar Mirror Film 1100
Solar Mirror Film 1100 is a flexible, reflective film designed to provide a high- performance, durable and cost- competitive solution for use in Concentrating Solar Power (CSP) installations.
Product Challenge
The primary roadblock to expanding the CSP market lies in the high cost and low durability of glass mirrors.
Problem Solved
Solar Mirror Film 1100 is 75% lighter and 15% cheaper than glass mirrors while maintaining a reflectance of more than 93% over 14 years.
Noteworthy
Solar Mirror Film 1100 is the result of extensive materials research, in-field studies and cooperative work with the National Renewable Energy Laboratory (NREL) dating back to the early 1990s.
Product In Detail
3M Solar Mirror Film 1100 combines a tough and durable polymer front-side with silver as its highly reflective layer. The film is then coated with a pressure-sensitive adhesive on the backside, which includes
Innovation
Solar Mirror Film 1100 holds a variety of benefits for solar concentrating applications. The film exhibits a total hemispherical reflectance greater than 94% and a specular reflectance above 95% (at 25 milliradian acceptance angle), making it suitable for a range of solar concentrating applications. Testing with the National Renewable Energy Laboratory (NREL) has demonstrated the films ability to maintain reflectance of more than 93% over 14 years.
shortlist
Solar industries are at mainstream economic status as costs reduce with increased performance. Nominations for the 2011 Solar Industry Awards allows the industry to applaud the innovators creating future foundations
a liner. An opaque pre-mask on the front surface protects Solar Mirror Film 1100 during assembly. The film is also lead- free, circumventing the environmental challenges associated with the disposal of traditional mirrors.
