Support for the performance and cost advantages of ReflecTech® Mirror Film in solar/scientific community :
Excerpt from Gary J. Jorgensen, Senior Scientist II, National Renewable Energy Laboratory, NREL to ReflecTech Communication, May 21, 2009:
“The measured spectral reflectance for the most recent sample (both as-received uncleaned and then cleaned) are significantly higher than the previous sample, indicating a loss in solar-weighted reflectance <0.5% in >6.25 years exposure.”
Excerpt from Gary J. Jorgensen, Senior Scientist II, National Renewable Energy Laboratory, "Report on Trip to Inspect ReflecTech™ Facets at SEGS VI on March 3, 2008":
“Based on the data reported herein, two important conclusions can be drawn. First, the ReflecTech material has exhibited excellent optical durability in terms of hemispherical reflectance (less than 1% loss across the solar spectrum after 5.25 years outdoor exposure in CA). Unlike many silvered polymer products in the past, the silver reflective layer has not corroded/degraded in this timeframe.”
Excerpt from Kennedy, C.E. and Terwilliger, K., “Dual 2004: Optical Durability of Candidate Solar Reflectors”, ISEC2004-65111, Proc. 2004 Solar Conf. and J. Sol. Energy Eng. Trans. ASME, July 2005:
“The viability of CSP systems requires the development of advanced reflector materials that are low in cost and maintain high specular reflectance for extended lifetimes under severe outdoor environment. A new polymeric solar reflective material has been developed through research collaboration with ReflecTech™ that combines experience gained from the development of ECP-305 and SS-95 and possesses unique and desirable properties for solar concentrators.”
Excerpt from Kennedy, C.E., Terwilliger, K., and Milbourne, M., “Development and Testing of Solar Reflectors”, NREL/520-36582, National Renewable Energy Laboratory, Presented at the 2004 DOE Solar Energy Technologies Program Review Meeting, October 25-28, 2004, Denver, Colorado:
“Accelerated ACUVEX® outdoor weathering tests (natural sunlight in Phoenix, AZ, is concentrated 7 to 8 times with a Fresnel-reflector while the samples are cooled with a fan to near ambient conditions and sprayed with deionized water 8 min per natural sun hour) are near a 10-year equivalent time period and show no significant loss in solar-weighted reflectance.”
