300L Flat Panel Solar Water Heater
300L Integrated Pressurized Copper Coating High Efficiency Flat Plate Solar Water Heater
Detailed Product Description
Flat-plate collectors are the most common solar collectors for use in solar water-heating systems in homes and in solar space heating.
A flat-plate collector consists basically of an insulated metal box with a glass or plastic cover (the glazing) and a dark-colored absorber plate.
Solar radiation is absorbed by the absorber plate and transferred to a fluid that circulates through the collector in tubes.
In an air-based collector the circulating fluid is air, whereas in a liquid-based collector it is usually water.
Flat-plate collectors heat the circulating fluid to a temperature considerably less than that of the boiling point of water and are best suited to applications where the demand temperature is 30-70°C (86-158°F) and/or for applications that require heat during the winter months.
Flat collectors can be mounted in a variety of ways, depending on the type of building, application, and size of collector. Options include mounting on a roof, in the roof itself, or free-standing.
