SunSource provides a simple variation on our popular Solaray AC forced-circulation glycol system. Rather than using a solar tank with an integral heat exchanger, the SunSource matches a basic solar water heater and a high performance SunEarth SunTherm or SunPlate external heat exchanger. Propylene glycol remains the heat exchange fluid. This simple variation gives the professional solar contractor flexibility to choose system components that may provide individual customers with better performance or overall system value.
If properly installed and maintained the SunSource forced-circulation glycol system can safely be deployed in areas that experience annual persistent hard freeze conditions. SRCC Rated Freeze Tolerance: – 30° F.
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.
