Solar Air Collectors:Know Their Ultimate Advantages and Applications

Solar air heating systems can inexpensively supply a major part of heat demand in a home or building using passive solar in combination with a solar powered PV fan. They draw in fresh air from outside and circulate it through a labyrinth of black aluminum solar air heating panels with a special selective coating to absorb maximum heat possible. Through a PV fan, this heated air is driven into the dwelling for transferring energy without further loss. This mechanism works best for the summer, spring and fall months while bringing an increase in internal temperature from 20-40 C (70-90 F)! In colder climate conditions such as Northern America, the outside temperature can go down to -30-40 F and in such situations the basic solar air collectors like SAH30 won’t be able to provide enough heat. However, the advanced models like SAH34 are designed to efficiently draw in air from the building or its basement and making it pass over the solar air heating panel to reheat and get blown into the living area. This is the smart technique which enables the solar air collectors to deliver enough of heat energy even in -40 F.

Today’s solar air heaters undoubtedly aim at minimizing the space heating costs and supplying warm clean heating by utilizing a renewable source of energy as much as possible.

The core part of any active solar air heating system consists of the solar air collectors, which capture and absorb most of the solar energy before converting it into heat. Presently, solar air collectors are not so widely used: On an international front, there is a limited number of manufacturers engaged in the production of solar air collector systems. The air collectors are all digitally thermostatically controlled so you can expect the fan to automatically turn off when a specific temperature is reached.

Placing the solar air collectors on a straight surface offering the best angle between the solar heating panel and the sun will yield better results in winter, spring, and autumn. The place must be in that direction where there is the highest scope for sun exposure with little obstructions.

Solar air collectors function in any sunlight condition, serving as a renewable supplement to any existing heating system at the daytime by saving around 50% of the energy cost.


They are the perfect choice for cottages, workshops or garages, trailers, even hunting shacks or ice fishing.


The main advantage of solar air collectors is that they are available in easy to install DIY kits; saving the homeowner the installation as well as investment cost. Another useful thing is that they don’t require wiring or electrical permits. There is completely no operating cost as the solar fan is run by a solar PV module on the collector. And the best part of all is the fan speed increases automatically with an increase in the sun’s intensity. There is little risk of solar air collectors overheating in the summer season as the users can make minor adjustments in the temperature setting to prevent the system from turning on. The digital thermostat is also powered by the solar panel in order to avoid the use of batteries or AC power.
