Solar Air Energy Systems For The Highest Possible Payback


Solar Air is arguably the most effective use of solar energy. Using a combination of passive solar and a solar powered PV Fan, hot air is circulated into the house or building provide warm clean heating.

Solar Air Heaters


Solar air Heating is recognized as one of the most economical way to heat a home using the suns energy. Payback for solar air heating is 1-4 years and that is before the federal tax credit of 30%!

The advantage of our solar air heaters are that they can be installed easily by any home owner which greatly reduces the overall investment cost. See Solar Air Collector installation guide. The other advantage of our solar air heaters is that they require no wiring or electrical permits. There is absolutely $0 operating cost as the solar fan is powered directly by a solar PV module on the collector. And best of all the fan automatically increases speeds as the sun’s intensity increases.

Unlike Solar Thermal Heating applications, solar air heaters do not over heat in the summer months. In the summer time simply adjust the temperature settings below the actual internal temperature and your solar air heater will never turn on. The digital thermostat operates via the solar panel so there is no need for batteries or AC power.

The solar air heaters works by drawing in fresh outside air and circulating through a maze of black aluminum that has a special selective coating that absorbs much more heat than it emits. This heated air is then blown it into the dwelling via a solar powered fan. This works great for the spring, summer and fall months and provides an increase of 20-40 C (70-90 F)! In colder climates such as Northern USA the outside air can drop to minus 30-40 F and as such the solar air heater would not be able to provide adequate heat. However, with the SAH34 You can simply draw in air from the basement or dwelling and reheat it back to the living area. In this way even in -40 the solar air heaters can provide useful heat energy!

The solar air heaters work best if placed directly on a south facing wall, alternatively a southern roof also works but then must be ducted into the house through the addict. Because hot air rises, the ducting into the house is best done at a lower level (closer to the floor) so that the heat can be utilized more effectively.
