SMALL-SIZE PHOTOVOLTAIC MODULES
The new photovoltaic modules GES/PV/20 have been designed for rural electrification, data survey,telecommunications and special applications. Thanks to their versatility, these modules are used for photovoltaic systems both in the developing countries and the European market. Their performance and reliability have been recently improved thanks to the introduction of high efficiency mono crystalline cells. At the typical battery operating voltage (12,5V) the PTLSOLAR™ technology, developed for high-efficiency modules range, allows a remarkable increase of the current output (about 10-17%) compared to the traditional modules. This feature makes these modules very suitable for systems with batteries and attractive for low-budget and special applications. Composed of 38 and 72 high-efficiency 165mm mono crystalline cells and they have been designed to operate under the toughest environmental conditions.
Up to now PTLSOLAR™ modules have guaranteed an average lifetime of more than 30 years.Easy and practical interconnections allow any voltage and configuration. A properly-designed anodized aluminium frame makes these modules safe, easy and quick to install in several situations.

MODULE PHYSICAL FEATURES
PTLSOLAR™ modules are made using the most advanced technologies, thanks to the wide experience gained by PTLSOLAR™ 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 PTLSOLAR™ modules. The corner/frame assembly system, devised in 1982, has proven to deliver mechanical strength and perfect electric continuity between the frame components.

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.
JUNCTION BOX
A waterproof, high capacity junction box with protection degree IP65 contains the by-pass diode and appropriate connection terminals. It is equipped with one PG9 cable glands for easy interconnections. The junction box is made always keeping in mind the requirements of the installers.
As a matter of fact:
- All the screws can be easily tightened using flat or star screwdrivers.
- The covers are fitted with self-retaining screws and hooked to the junction box, for easy handling and maintenance.
- All the connections are soldered for very long durability and reliability.
- Connection terminals and by-pass diodes are mounted on a PC board for easy replacement in case of damage by lightning.
