SunSiphon SRCC OG-300 System Ratings

The Solar Rating & Certification Corporation OG-300 systems level rating is an independent assessment of both system reliability and performance. Systems that receive this rating must meet HUD minimum property standards in addition to a rigorous review performed by SRCC staff and design review team. Once the system has passed these quality assurance checks it undergoes a full performance analysis to estimate the actual solar contribution of the system towards an average hot water load. This contribution, as defined by the Solar Energy Factor is listed alongside the different variants of each system type.

The SRCC provides the following description for SunEarth CopperHeart Systems:
Glazed Flat-Plate Collector, No Controller, Mantle Heat Exchanger, No Load Side Heat
Exchanger, Fluid Class II, Freeze Tolerance 32 F
