For maximum cost efficiency and reliability you won’t find a better collector than those manufactured by Alternate Energy Technologies. Each collector is carefully crafted under strict quality control management. Careful design and assembly ensure that your collector will be aesthetically pleasing and structurally sound.

These collectors come in six different size configurations to optimize for job type or container shipping:
(all collectors are 7.94 cm deep)
AE-40, 307.82 cm x 119.86 cm, 72.55 kg;
AE-32, 246.86 cm x 119.86 cm, 51.24 kg;
AE-26, 196.06 cm x 119.86 cm, 40.81 kg (best size for export); AE-24, 246.86 cm x 89.38 cm, 51.69 kg;
AE-21, 216.38 cm x 89.38 cm, 45.34 kg.

All collectors have been tested under ASHRAE 93-86 conditions and yield the following efficiency equation:

Eff. = 76.5 – 413(Ti-Ta)/I

Where units of (Ti-Ta)/I are in 0C/Watt/m2.

When it comes to packaging these into containers the following applies:

In Many countries a great door is opened if the collectors are assembled by local labor. Import restrictions are often waved, and local economies benefit from the jobs created from the assembly of the collectors. SKD collectors come in all of our mentioned models. SKD collectors are not assembled, and do not have insulation supplied. Collectors are totally pre-manufactured to the same exacting tolerances of standard collectors, and may be assembled with simple hand tools. Larger numbers of SKD collectors may be shipped in a container than standard collectors; thus, lowering the landed cost. SKD collectors themselves are priced lower than
standard collectors as well. This is the preferred method of import by many of our international clients.

AET is one of the largest outlets for AFG Tempered Solar Glass in the World. Years of experience has shown that there is no substitute for tempered low iron glass. It has the durability and longevity needed for any solar appliacation. It provides 91% transmission (at 00 incidence angle and 0.3175 cm thinck) of solar radiation, and is opaque to infrared.

We can supply your replacement glass needs or simply supply the highest quality glazing for collectors of your own manufacture. We have readily available the following 5 sizes:

RG-40, 116.84 cm x 304 cm x 0.397 cm, 43.5 kg
RG-32, 116.84 cm x 243.84 cm x 0.3175 cm, 23.2 kg
RG-26, 116.84 cm x 193.04 cm x 0.3175 cm, 18.9 kg
RG-24, 86.36 cm x 243.84 cm x 0.3175 cm, 17.4 kg
RG-21, 86.36 cm x 213.36 cm x 0.3175 cm, 15.2 kg

The absorber plate/riser tube assembly is available in the following sizes (custom sizes are regularly done):
AP-50, 377.83 cm x 111.13 cm, 23.1 kg;
AP-40, 294.64 cm x 113.67 cm, 14.9 kg;
AP-26, 182.88 cm x 113.67 cm, 13.0 kg;
AP-24, 223.68 cm x 82.04 cm, 11.7 kg;
AP-21, 203.2 cm x 82.04 cm, 10.4 kg.
The riser tubes are 1.27 cm ID. These are available wit header tubes of both 2.54 cm ID and 3.81 cm ID or no header tube. Other size header tubes are available upon request.

AET Absorber plates

AET uses only extruded aluminum in all of its collector frame types. It is available in two different standard profiles, and is available in custom sizes. Both electrostatic paint and anodized finishes are available. Mounting hardware is also from aluminum extrusions and is used with stainless steel fasteners. The mounting hardware and the frames are designed to interlock without penetrating the frame wall or the use of power tools. Simple hand tools are used to lock the hardware in place on the frame. Mounting hardware is available for mounting to racks, flush roofs, and hinged configurations.

Years of experience have taught AET that steel and other ferrous metals simply cannot withstand the environmental pressures of heat, moisture, and wind induced stress over time. When properly assembled our frames (when glazed with our tempered glass) can withstand wind induced pressure differentials of in excess of 4 kPa. This translates into a wind velocity of 280 km/h with no damage.
