products: Q Solar A1D
The small solar panel on top generates the electric current that actuates the fan of the solar air heater.
- size: 1m2 (0.95m x 1.2m, or about 3' x 4')
- heating capability: can heat a small room during sunny winter days, or a few such solar air heaters can heat a larger room
- it cools indirectly during summer days, by shadowing the wall.
- energy output: depending on the solar radiation available, it can deliver up to 9MJ (3kWh) of heat per day, that would have cost you about 50 cents per day if using an electric heater
- warranty: 5 years replacement warranty
- performance: during sunny days it can raise the temperature of the outside air by about 30 degrees Celsius (86 degrees Fahrenheit)
- fan upkeep: its fan is powered by the solar panel, so it costs nothing to run
- installation: comes as a kit that can easily be installed by a handy person
- price: AUD 250 (includes solar air heater, 12V fan, solar panel that actuates and the fan). Alternatively, if you have at least 5W of 12V direct current (DC) available from your already existing solar panel or from a 12V DC power adaptor (inexpensive and found at all electrical shops), then we can provide for AUD 200 the solar air heater with a 12V fan but without the solar panel. Australian customers should add 10% GST to the listed international price.
- advantages: it is about 4 times more economical than models of the same performance of our competitors, therefore it is more environmentally friendly; we have learned from nature to do the most with few resources.
