Types of Panel

• Evacuated-tube collectors Glass tubes with selectively

coated absorbers inside transferring energy to heat. Most efficient at above 82°C(180°F).

• Concentrating collectors Concave mirror with focal point

directed to an absorber or receiver. Can reach higher temperature than Flat-plate and evacuated-tube collectors.

Your home and the system

• Installation varies depending on size of family, tanker, and solar system; type of roof, building codes, and collectors. Usually range from $1,500 to $3,000.
