SunEarth ThermoRay 120-Gallon Complete Solar System
SunEarth ThermoRay 120-Gallon Complete Solar System Review
The SunEarth ThermoRay 120-Gallon Complete Solar System is SunEarth's largest complete solar water heating package. 120-gallon storage with 3-4 SunEarth collectors for heavy demand profiles.
Specs: 120-gallon storage tank with internal heat exchanger, 3-4 SunEarth Empire collectors (sub-system dependent), circulation pump, differential controller, expansion tank. SRCC certified system rating.
The 120-gallon storage + multiple collectors handles large household demand (5+ people) with high sun-fraction (60-80% in good climates). Right answer for solar water heating installations where typical 80-gallon storage would be insufficient.
About $9,500-$13,500 installed depending on regional install costs. Federal Section 25D credit (30% of install) reduces net cost meaningfully.
Right buyer: large household in regions with strong sun exposure wanting comprehensive solar water heating coverage.
- 10-year warranty — solid above-average coverage for this class
- Large 120-gallon reserve — comfortably serves 5+ person households in peak-use periods
- Professional installation required — gas/venting/electrical work adds $500–1,500 to unit cost
