SolFocus: Factory to Field


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

SF-1100 Designed for Reliability


SolFocus Utilizes Reflective versus Refractive Optics
