Passive solar heat collection devices include: greenhouses, sunrooms, skylights, windows, trombe walls, solar wood kilns, solar grain dryers, solar dehydrators, and solar hot air collectors.
These structures, or simply areas of glazing (windows, etc.), are oriented within 45º of true south and are covered with a glazing material. Inexpensive and virtually unbreakable polycarbonate is an excellent glazing material to use. Polycarb is easy to install and has a high level of light and solar transmission.
