Solar Air Heating Collector Performance Tests — Which DIY Collector Design is Most Efficient?

Air is light in weight and low in heat capacity, so a lot of air needs to be passed through an air heating collector, and it has to be done in a way that puts a lot of the air in good thermal contact with the absorber.

If a significant amount of solar heat gets transferred around to the back so that the back, front and sides of the downspout collector are all hot, then this increases the absorber to air heat transfer area, which is a major consideration on solar air heating collector.

As examples: energy demand can be balanced between day time and night time; summer heat from solar collectors can be stored interseasonally for use in winter; and cold obtained from winter air can be provided for summer air conditioning.

For extra support, an earth heat collector can cool air in summer and heat air in winter.

Systems providing less than 40 % of the heat needed for a home are rarely cost - effective except when using solar air heater collectors that heat one or two rooms and require no heat storage.
