HOW SOLAR AIR HEATERS WORK
Solar air heaters, also called collectors, trap the sun’s rays to produce heat. They are mostly used to heat homes
and water. Most solar collectors are boxes, frames, or rooms that contain these parts:
• Clear covers that let in solar energy
• Dark surfaces inside, called absorber plates, that soak up heat
• Insulation materials to prevent heat from escaping
• Vents or pipes that carry the heated air or liquid from inside the collector to where it can be used.
