MODULE PHYSICAL FEATURES Helios Technology modules are made using the most advanced technologies, thanks to the wide experience gained by Helios Technology in the PV field and the suggestions coming from skilled installers. The result is a frame with 4 slotted holes, practical and compact, which allows a quick and easy installation of all Helios Technology’s modules. The corner/frame assembly system, devised by Helios Technology in 1982, has proven its high efficiency guaranteeing mechanical strength and perfect electric continuity between the frame components. Thanks to this system a better safety in high-voltage systems will be allowed. MODULE CROSS SECTION The cells are laminated in permanent way between sheets of ethylene vinyl acetate (EVA), tempered glass and white Tedlar, in order to offer an ideal protection against humidity penetration and salty corrosion. The tempered glass whose main characteristic is the high transparence to the direct and diffused light, is fixed to the frame by silicone sealant which assures an efficient protection against mechanical and environmental stress. The high insolation between the cells and the frame reduces the risks of current leakages which are often the main cause of power losses in high-voltage PV installations. JUNCTION BOX A waterproof, high capacity junction box with protection degree IP65 contains four by-pass diodes and appropriate connection terminals. It is equipped with two M16 cable glands for easy interconnections. The junction box is made always keeping in mind the requirements of the installers. As a matter of fact: 1. All the screws can be easily tightened using flat or star screwdrivers. 2. The covers are fitted with self-retaining screws and hooked to the junction box, for easy handling and maintenance. 3. All the connections are soldered for very long durability and reliability. 4. Connection terminals and by-pass diodes are mounted on a PC board for easy replacement in case of damage by lightning.
