Offgridtec® OLP 150W V2 Solar Panel 19V Shingle Technology PERC

The Offgridtec OLP 150W V2 (MPN: 018480) is a powerful solar module in a full black design. It offers optimized light output and a compact design that allows for flexible installations. With its overlapping wafer design and advanced PERC technology, it guarantees outstanding performance and is ideal for versatile applications that require a powerful energy source

It is the improved version of the popular OLP 155W 12V solar module (MPN 3-01-011075). The higher short-circuit current improves module performance, while the increased system voltage of 1000 VDC allows integration into new and existing solar systems. In the new version, the solar modules are equipped with both improved solar cells and 11 busbars, which leads to improved light absorption and reduces the effect of partial shading.

Overlapping design

The overlapping in the wafer design of monocrystalline solar modules is crucial for their exceptionally high module efficiency. It enables more precise use of the available surface area, minimizes power losses through reduced line resistance, and limits material losses during production. The targeted arrangement of the wafers effectively minimizes gaps between them, thereby increasing power density and optimizing the overall efficiency of the modules. This method is therefore particularly advantageous for solar applications in rooms with limited space, as it maximizes energy production per unit area.

Innovative PERC technology

PERC technology, also known as Passivated Emitter Rear Cell or rear passivation, is a key technology in Offgridtec OLP solar modules that increases the efficiency of solar cells. It creates a dielectric layer between the conventional aluminum metallization and the silicon wafer layer on the back of the cell. This layer is treated with a laser that creates tiny holes. This dielectric layer reflects light that would normally penetrate to the rear without generating charge carriers back into the solar cell. This gives photons an additional chance to generate electricity. PERC technology improves efficiency across different wavelengths, increases the likelihood that electrons will contribute to power generation, and helps to reduce system costs and increase energy yield per unit area.
