Although solar water heating systems all use the same basic method for capturing and transferring solar energy, they do so with three specific technologies that distinguish different collectors and systems. The distinctions are important because different water heating needs in various locations are best served by certain types of collectors and systems. Apricus collectors are excellent for year round water heating applications in North America!

Solar Collector efficiency comparisons:

Solar Collector efficiency

Solar collector efficiency is plotted as a straight line against the parameter (Tc-Ta)/I, where Tc is the collector inlet temperature (C), Ta is the ambient air temperature (C), and I is the intensity of the solar radiation (W/m²). Notice that flat plate collectors work at low ambient temperatures (when it is hot out), but efficiency drops off drastically as the temperature of the hot water needed increases.

Apricus evacuated tube collectors have a number of advantages over older style flat plate: Evacuated tube collectors work on overcast days, in colder weather, and the tubes can be installed or removed individually without special tools. The evacuated tubes act like giant thermos, allowing 93% of the sun's radiation in, but only 3 to 5% out. This design allows the system to work in very low temperatures (down to about -40°F). This is achieved because the thermal conduction and convection losses are almost nothing (under 2%) because of the vacuum gap. Apricus Evacuated tube collectors are designed to function year round and they offer the best performance over a wide range of applications that require efficiently achieving higher temperatures.

Why Apricus evacuated tubes? Your entire solar water heating system hinges on the long term efficiency of your collectors! Individuals looking for high performance high quality collectors should always look for products that are SRCC-Certified., and manufactured by companies that have international ISO9001:2000 certification.
