SolarWorld Sunmodule SW 345 XL MONO Solar Panel Review

Tested For Heavy Loads

With a maximum load capacity of up to 5400 Pa, SolarWorld Sunmodules are designed to withstand heavy accumulations of snow and ice.

Plus Sorting Certified

Plus‑Sorting guarantees highest system efficiency. SolarWorld only delivers modules that have greater than or equal to the nameplate rated power. The positive power tolerance guarantees utmost system efficiency. Only modules achieving or exceeding the designated nominal power in performance tests are dispatched. The power tolerance ranges between -0 Wp and +5 Wp.

High Quality Textured Glass

Optimized surface structure: The proprietary surface coatings and granular texture of the Sunmodule’s front glass create two effects: the reduction of the light reflected from the outside (air-glass interface) and the internal trapping of the light reflected from the solar cells in the module (light-trapping). These two effects combine to make an extremely efficient and high performance PV module.

1000 VDC Validation Tested

The certification to international standards provides additional assurance that SolarWorld solar panels are suitable for use in systems with greater than 600 Vdc string voltage.

TÜV Power Controlled

The TÜV Rheinland “Power Controlled” inspection mark guarantees that an independent test provider certifies that the power ratings specified for our solar panels are maintained and regularly monitored. The performance of our solar panels exhibits a mere 2 percent measuring tolerance. No other manufacturer can claim such precise performance.

Made In Germany

This SW 345 XL Mono solar panel is constructed in Germany with domestic and foreign sourced components from reputable manufacturers.
