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.
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.

Air Heating Collector Performance Tests — Which DIY Collector Design is Most Efficient?
A side by side test of two of the most popular solar
air heating collector designs: the pop can absorber and screen absorber.
This is a variation on SolarWall's well know transpired solar
air heating collector system.
But, producing higher temperatures normally means that the solar
air heating collectors would operate less efficiently as the losses out the collector glazing go up with collector temperature — thus the desire for high storage temperatures can result in an undesirable increase in collector area.

Air heated by a solar
collector rose up a chimney through racks, with screens holding the fresh chiltepíns — a much more efficient method.
Powered by wasted
heat from the incinerator, the
collectors use fans to suck ambient
air into filters, which absorb carbon dioxide.

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.
Active solar: As an energy source, energy from the sun collected and stored using mechanical pumps or fans to circulate
heat - laden fluids or
air between solar
collectors and a building.
Each column of
collector glazing has corrugated aluminum behind it, and as the
air heats up, it rises naturally.
The SolarWall
collectors draw in the
heated air behind the PV panels.
Cooler glazing temperatures would indicate that
collector heated air is not working its way out to the glazing and warming it, and / or that the glazing was seeing less radiation
heating from the absorber screens.
The first layer of mesh runs relatively cool in part because in this
heating scheme, the
air introduced into the
collector is relatively cool (70F) room
air — this cooler first layer of mesh thus reduces losses out the glazing.
Outdoor units serve as the
collector for
air source
heat pumps, including clockwise from above left, units from Mitsubishi and Panasonic (installed as part of Tipperary Energy Agency's SuperHomes retrofit scheme), CTC (an illustration showing the inner workings), and a Thermia unit outside Ireland's first certified passive house retrofit, in Salthill, Co..
Preheating combustion
air with waste
heat from the plant will also increase efficiency, and some plants are considering schemes to use solar thermal
collectors as
air preheaters during daylight hours.
Solar systems for
heating water or
air usually have nonconcentrating
collectors.
Fans or pumps circulate
air or
heat - absorbing liquids through
collectors and then transfer the
heated fluid directly to a room or to a
heat storage system.
