WORLD S 2 MM SOLAR GLASS

Transcription

1 WORLD S FIRST MM HIGH PERFORMANCE FULLY TEMPERED SOLAR GLASS

2 ONE TECHNOLOGY MANY ADVANTAGES Bi-facial modules deliver upto 3% more power Increased module life upto 4 years Higher reliability - reduced rate of module failure Use laminated modules as a roof itself Easier installation Substitutes traditional roofing sheet PRODUCT Low iron high transmission fully tempered solar glass NEW. MM.5 MM STANDARD 3. MM 4. MM.8 MM MECHANICAL STRENGTH Minimum 9 Mpa as per EN 115-1:15. Glass-to-glass modules made with fully tempered. MM glass can withstand High wind loads > 4 Pa Snow loads > 54 Pa.

MM + 3. MM TPO Butyl No -% -1% Glass-to-glass module is 7 times more water vapor diffusion tight. PV cells in glass-to-glass modules are best protected against moisture and difficult environment conditions as under: Tropic climate conditions with high humidity and temperature Salt water on the modules and high UV radiation Mechanical forces due to twisting of the platform
