PHOTOVOLTAIC MODULES

SMALL-SIZE PHOTOVOLTAIC MODULES

The new photovoltaic modules H245, H272, H372 have been designed by Helios Technology for rural electrification, data survey, telecommunications and special applications. Thanks to their high versatility, these modules are very appreciated and 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 I-Max

®

monocrystalline cells. At the typical battery operating voltage (12,5V) the I-Max

®

technology, developed by Helios Technology for its 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.

H372 – 40W

These modules are composed of 38 and 72 high-efficiency I-Max

®

165mm monocrystalline cells and they have been designed to operate under the toughest environmental conditions. Up to now Helios Technology’s modules have guaranteed an average lifetime more than 30 years.

H272 – 30W

Every cell and module are tested several times throughout the manufacturing process. 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.
