SolaRay PV: Water Heating Systems

The SolaRay PV domestic solar water heating system has gone through an extensive design, technical and performance review by the Solar Rating & Certification Corporation (ICC-SRCC).

SunEarth SolaRay PV solar water heating systems can be protected against freeze damage to temperatures as low as -60°F (-51°C). This system should not be installed in any area that has experienced ambient air temperatures below -60°F.

System performance varies as a function of the household hot water load, including daily showers, laundry and kitchen uses, average ground water and ambient air temperatures, the home’s roof pitch and orientation, and, of course, the seasonal intensity of solar radiation. These variables, some of which change from home to home on the same neighborhood street, will determine how much energy and money your SolaRay PV system will save on an annual basis.

Your SolaRay PV solar system is known as a "forced circulation" system because it utilizes a mechanical pump to efficiently circulate the Dow Chemical Dowfrost HD propylene glycol heat transfer fluid (HTF) throughout the system. The HTF protects the collector piping from freezing and inhibits scaling deposits that can reduce performance in indirect systems utilizing potable water as the HTF. Proper application and maintenance of the HTF can protect your Solaray PVsolar water heating system to minus 60° Fahrenheit.
