Approach• Thorough reliability analysis throughout design (FMEA)
• Extensive accelerated aging in environmental chambers (HALT)
• Statistically large volume field data correlated with HALT
Panel• Glass, Aluminum, Steel - no plastic in optics path
• Compact panel for better environmental control
• Passive air cooling – no pumps, fluid, valves
Tracker• Electric drive - less maintenance than hydraulic
• Pole-mount tracker has fewer moving parts than other designs
