AE-Series "Flat Panel" Solar Thermal Collectors, manufactured in The United States by Alternate Energy Technologies (AET), are designed to meet the needs of any solar system including solar hot water, space heating, radiant floor heating or industrial process heat. AET is dedicated to building the AE-Series Collectors from the finest materials and with the highest standards of craftsmanship

AE Series Collector Features:

• Wind load tested to 195 MPH
• Crystal Clear™ selective coatings
• Extruded aluminum frame and battens
•Thermax™ polyisocyanurate foam insulation
• Aircraft aluminum pin grip rivets
• 30+ year design life
• 10 year warranty
• Proudly made in the U.S.A.
• THERMAFIN ™ absorber plates
• Quick-lock mounting hardware


Crystal Clear™ Selective Coating
The Crystal Clear™ Solar-Selective coating is technically a Quartz Encapsulated Bimetallic Alloy. Thousands of nanocrystalline
growth projections dramatically increase the surface area of the absorber plate for maximum solar radiation absorption and
performance. Crystal Clear™ has been tested for over 1450 hours at 617o F continuously with minimal visible or physical
degradation of its thermal characteristics. Furthermore, Crystal Clear™ by itself enhances the thermal performance of the
absorbers by an additional 3%. The finished coating hosts an Absorptivity of > 0.96 & Emissivity of < 0.08

THERMAFIN™ Absorbers
AET Introduced THERMAFIN™ absorbers into the AE-Series collectors in 1996. Through extensive research and
development, we have employed the best heat transfer method in the world today. THERMAFIN's high-frequency,
forge weld process molecularly bonds the fin to the tube providing long-lasting performance and durability while
allowing the highest heat conduction. The high-frequency welded joints will not weaken, expand, or pull apart and
are backed by a written 30 year guarantee.

Baked Polyester C-Channel Construction
Our AE-Series Collector frames are fabricated in our state-of-the-art manufacturing plant located in Jacksonville, Florida.
Crafted using extruded baked polyester (MB-40) electrostatic bronze painted aluminum and securely fastened with aircraft
grade pin grip rivets, AE-Series Collectors are built to withstand the most demanding environments.

Technical Specifications:


AE-Series Collectors with exclusive selective "Crystal Clear" inside

Low-Iron tempered glass, exclusively using our "High-T" tempered glass, with a total solar energy transmission of 90%.

Collector Frame and Battens:
Type 6063-T6 extruded aluminum frame and battens with electrostatic bronze plate finish that facilitates long life and strength.

Polyisocyanurate foam board insulation. Foil-faced, glass fiber- reinforced, rigid board Thermax sheathing (1-1/4" in the bed / 3/4" in the sidewalls).

Mounting Hardware:
The variable "Quick Lock" mounting hardware reduces mounting time and makes it simple for anyone to install. The Quick Lock System allows the highest flexibility in mounting and is tested to wind load conditions of 195 mph. Mounting possibilities include: Pitched roof, Flat roof, Ground, Balcony, and Facade mounting.

Absorber Plate:
Manufactured by Thermafin™ Mfg., a 100% copper absorber plate, the fin and the riser tube are molecularly bonded by high- frequency forge welding.

Absorber Coating:
Exclusively by Thermafin™ Mfg., a Selective "Crystal Clear" Coating, a = 0.96 e = 0.08

Gasket Grommets:
A UV durable EPDM, U-channel gasket with molded corners which prohibits water penetration and assures long life. Extruded Silicone Grommet with 1-1/8" Bore.

Corner Bracket:
Architectural aluminum angles inside with aircraft-grade pin grip rivets to ensure high stability.

5056 Aluminum rivets secure the backsheet. Batten screws are 18-8 SS, 10-24 x 3/8", hex head screws, and black oxide coated.

Type 3105-H14, 0.019" stucco embossed aluminum sheet (bronze) pop-riveted to aluminum frame.

Mounting Hardware Options

AET's exclusive "Quick Lock" mounting systems allow for virtually any collector orientation and mounting. Collectors can be mounted to any roof, vertical wall, fascia boards, pre-constructed racks or ground mount systems. The framewall and mount have been certified to withstand 180 mph winds. The framewall will accept the mounts anywhere around the collector without drilling or tapping, so the integrity of the framewall is not violated. The rear struts can be cut to any length allowing proper elevation and orientation.
