The Offgridtec olp 155w (mpn 3-01-011075) is a powerful 12v solar module with innovative overlapping design wafer assembly and features dimensions that until now only high-performance solar modules could achieve. The shingle arrangement of the wafers ensures an optimal current flow through minimized power losses and a significantly higher module efficiency through better space utilization. The perc technology used improves light absorption and increases the power yield.

Unique selling points of the olp series of Offgridtec

  • Unique module design with overlapping wafer arrangement (overlapping design) ensures very high module efficiency through better area utilization and reduced power losses due to line resistances.
  • Modern, homogeneous appearance without visible conductor tracks.
  • Innovative perc technology ensures improved absorption at longer wavelengths, e.g. at flat irradiation angles (early morning or evening) or in cloudy conditions
  • No hotspot hazard
  • Less loss in case of partial shading
  • Thanks to finishing according to overlapping design, the module has a footprint of just 650 x 1310 x 35mm at a rated power of 155w. The cell efficiency is over 23%.

Innovative perc technology

The perc technology (Passivated Emitter Rear Cell) in the Offgridtec olp solar modules ensures a higher efficiency of the solar cells with its key technology. A dielectric layer is created on the back of the cell between the conventional aluminum metallization and the silicon wafer layer, which is provided with tiny holes by a laser. This dielectric layer reflects light, which penetrates to the back side without generating charge carriers, into the solar cell. The reflection gives the photons a "second chance" to generate electricity. In addition to higher efficiency at different wavelengths and the increased likelihood that electrons will contribute to power, perc technology contributes to lower system costs and an increase in area energy yield.
