Product Features

  • Made of copper tubes and aluminum fins, with ultrasonic welding and highly efficient anodized oxidization selective coating (all metal, no plastic).
  • Size of each panel: 40 x 40 x 1. Absorber area: 10 square feet per panel.
  • Two panels together can heat a 40 gallon water tank up to 130 degrees F. Panels' internal temperature can reach over boiling temperature (very hot) in the insulating box when the water inside is not flowing. (The Department of Energy website suggests 1.5~2 gallons of storage per square foot of collector area. That is about 20 gallons per panel).
  • Compatible with electric or gas hot water heater. Work under normal house water pressure (30 ~100 psi). Each panel is tested up to pressures of 15 bar (217 psi).
  • Inlet and outlet copper tubes are size 3/4, outer diameter about 7/8 and 0.03 thick. Panel can be connected to a water (heater) tank with or without a pump, depending on the locations of the tank and panel. If the panel is positioned below or level with the tank, no pump needed. If panel is positioned above the tank, a circulating pump and controller are needed.

Product Description

These are two professional solar water heating panels without the insulating box, made by a solar collector manufacturer in China. Usually it is sold inside an insulated, glass-covered box as one unit at a much higher price. You can make your own box, or you can place the panel on the roof without the box if you live in the South. These highly efficient solar thermal panels are ideal for many applications: 1.Residential water heating & space heating. (Homes, mobile homes, cabins). 2.Commercial water heating & space heating. (Schools, offices, clinics, warehouses & factories). 3.Outdoor hot water. (Spa & pool, farm & ranch). - Not recommended for use during freezing weather without antifreeze protection. Panels need to be drained during freezing weather if no antifreeze is inside. On rainy or cloudy days, electricity or gas needs turned on as backup. - Panel with insulating box can be used for supplemental winter space heating, when connected to a heat exchanger, a radiator or radiant floor, as shown in the figure above. You may consider using propylene glycol (non-toxic antifreeze liquid) in the collector-radiator loop, mixed with water in concentrations that will prevent damage from freezing to the lowest anticipated temperatures in your region. - Ship to the lower 48 states only by FedEx Ground. Insurance included. No international shipping. - Returns accepted within 30 days after the item is delivered. The buyer pays shipping. ....read more
