Flat plate
solar collectors consist of a thin, dark metal absorber sheet that’s backed by a grid or coil of fluid tubing.
The absorber sheet is sealed inside an insulated casing with a glass or polycarbonate cover. Fluid is
circulated through the tubing, gathering the heat from the metal absorber sheet and transporting it to a
super-insulated solar hot water storage tank.

The Best Applications For Flat Plate Collectors
A flat plate solar collector can be less efficient than
evacuated tubes in colder months and more efficient in warmer months.
They work best in temperatures above 20 degrees Fahrenheit, and on roofs that have perfect southern exposure.
They are also great for seasonal homes and businesses that don’t operate in the winter months.
Sundog Solar Store offers a variety of flat plate collectors including Sunda and Stiebel Eltron.
