Offgridtec® ETFE-AL 120W 20V Semiflex Solar Panel with Integrated Aluminium Plate

Intro

The modules of the new Offgridtec ETFE-Alu series are based on a pioneering material composition of ETFE and aluminium on the front or back, as well as the 5 Busbar cell construction with efficient monocrystalline solar cells as the centrepiece and thus set new standards in terms of durability, efficiency and flexibility.
Numerous unique selling features of the Offgridtec ETFE-ALU series: innovative structure of the outer ETFE layer – thus significantly improved slip inhibition and higher light transmission than conventional modules with ETFE coating – even strong hail, salt water or entering the modules are no problem.
Thanks to the integrated aluminium backsheet, the formation of cell cracks and the resulting premature loss of function due to assembly or handling errors is almost eliminated. Pre-installed connection cables with 90 cm length and MC4 connectors make installation easier.

Offgridtec ETFE-ALU 120W semi flexible solar module

The 120W semi flexible solar module by Offgridtec (3-01-011050) is based on a new, pioneering material-composition (Aluminium-ETFE) and is equipped with highly effective mono cells from Germany.

The output voltage of 24V DC makes the module interesting for a bunch of application scenarios. Furthermore it is walkable and clearly non-slip than its predecessor, so it’s the very best choice for navy- and mobile section.

The current is provided by highly modern Solarworld cells, which show a considerably cell efficiency and also stand out from the crowd with low performance degradation values.

The ETFE-ALU series by Offgridtec

  • 2 overlapped ETFe-layers on the module front provide a solid protection of the inside cells and a high light output over many years
  • Thanks to a new structure of the outer layer, the slip resistance used to be clearly improved and on the module can also be walked trouble-free
  • Long-term the ETFE-front-layers offer a higher income through better light transmission, significantly less cloudiness and provide a solid protection against hail and salt water
  • Electricity-Management through 5 busbars, so a solid throughput without heat loss can also be provided, even at high currents
  • Integrated alu-backsheet nearly prevents the arise of cell cracks through mistaken handling or mounting
  • The integrated solarworld solar cells (made in Germany) offer a high cell efficiency of 20,6%. The module finishing is accomplished the usage of the most modern manufacturing processes
