SunEarth Empire EP-40-D Solar Water Heating Collector Review

The SunEarth Empire EP-40-D is a flat-plate solar thermal collector for residential solar water heating. SunEarth is a US-based premium solar collector manufacturer. Used in conjunction with a storage tank and circulation pump in complete solar water heating installations.

Specs: 40 sq ft absorber area, copper absorber plate with selective black coating, tempered low-iron glass cover, aluminum frame. Designed for rooftop or ground mount. SRCC certified.

SunEarth positioning competes with Heliodyne in the US-made premium solar collector segment. The Empire EP-40 is their flagship residential flat-plate collector — high efficiency, durable construction, 10-year warranty.

Typical residential system uses 2-4 collectors with an 80-gallon storage tank. About $1,500-$1,900 per collector. Complete system: $5,500-$9,500 installed.

Right buyer: solar water heating installation in regions with strong sun exposure (California, Arizona, Hawaii, parts of Florida) and existing solar thermal infrastructure. For most US homes, rooftop PV + heat-pump water heater is the more cost-effective alternative.
