SOLARAWARDS2011 WINNERS
Industry winners
After an exceptional reponse from the international solar community this year’s Solar Industry Awards have been decided and the winning companies gathered in Hamburg recently to celebrate the awards and to share their success. Each year the programme grows and we are pleased to present this year’s winners.
SOLAR Materials Enabling Award 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 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.
Innovation: Solar Mirror Film 1100 has proven to hold 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 broad range of solar concentrating applications. Furthermore, testing with the National Renewable Energy Laboratory (NREL) has demonstrated the films ability to maintain reflectance of more than 93 % over 14 years.
Customer Benefits: 3M Solar Mirror Film 1100 enables greater design flexibility than standard glass, allowing for larger geometry reflectors than previously possible. The lightweight, large-area assemblies possible with Solar Mirror Film 1100 have the potential to reduce the total installed cost of CSP systems by
Note from the Judges: Materials have become a key enabler across a great deal of technology manufacturing and solar is no different. The winning entry in this category has provided a material solution for Concentrated Solar Power. A primary roadblock to expanding the CSP market lies in the high cost and low durability of glass mirrors. The winning product 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.The winning entry is a film that exhibits a total hemispherical reflectance greater than 94 % and a specular reflectance above 95. Testing with the National Renewable Energy Laboratory (NREL) has demonstrated the films ability to maintain reflectance of more than 93 % over 14 years.
Thin Film Innovation Award
more than 15 %. Additionally, reflective film-based reflectors are up to 75 % lighter than glass mirrors, significantly reducing transportation costs while easing the installation process.
THINFAB
Product Description: Oerlikon Solars next generation fab THINFAB will enable total module production cost at or below 0.5 €/Wp and a 120 MWp output capacity. Oerlikon recognized that for PV to become a significant source for energy amongst the traditional energy sources, solar power had to become economically viable. With the THINFAB with module manufacturing cost at 0.5 €/Wp, energy can be produced at 0.10 €/kWh in for example Southern Europe. In many regions of the world this allows energy production at or below grid parity level. Due to highest equipment availability, reduced process steps in the backend and highly optimized line concept (to balance frontend and backend takt times), Oerlikon Solars THINFAB reaches highest uptime with lowest non-productive time. The performance figures of this thin film silicon turnkey solution are as following: - Module Efficiency 10 % - Yield 97 % - Annual Output 120 MWp - 0.5 €/Wp.
