Solar Air Heat Basics


Solar energy technologies fall into one of two primary categories:  solar electric and solar thermal.  Solar thermal, or solar heat, was first deployed in the US in the 19th century and is a tried and tested method of delivering heat.

Modern solar air heating panels are typically mounted vertically on south-facing walls, where solar exposure is greatest.  This maximizes heating season performance, minimizes costs, and maintains the building’s aesthetics.

Solar energy striking the collector(s) passes through the high-transmittance solar glazing and heats the highly efficient absorber plate.

When there is heat available in the collector(s) and the building requires heat, simple controls automatically activate the fan.

The fan moves air through the collector(s), where it is heated, and then redistributed to the building using conventional, off-the-shelf, HVAC ducting and air handling equipment.

Check valves prevent reverse thermo-siphoning and uncalled-for heat, so you get clean, free, solar heat only when you want.

Solar air heat is often the most efficient and cost competitive solar technology available in colder climates, saving clients many thousands of dollars and eliminating toxic emissions!
