Sunmodule SW 340 XL Mono PERC
340W XL Monocrystalline Solar Panel, 24V

The SolarWorld 340 Watt monocrystalline solar panels feature PERC cell technology which all them to harvest more sunlight, and ultimately more power over the life of your system. In 2012, SolarWorld pioneered the first mass-produced PERC cells and today remains the global volume leader in PERC production capacity. SolarWorld cells hold the world record for industrial mono-PERC efficiency: 22.04% ! (Fraunhofer Institute)

Unique benefits of SolarWorld PERC (Passivated Emitter Rear Contact) Cells (see DOCUMENTS tab above for more info):


  • Harvest more energy from sunlight than standard silicon cells in any given moment
  • Increase each panel's power output by up to 20 watts
  • Generate less heat than traditional cells
  • Improve system performance during low light periods of the day (ie. early morning, late afternoon, cloudy days)
  • Increase total energy yield over time

    The SolarWorld Sunmodule SW 340 solar panel in the 300 watt solar panel family, and offers SolarWorld's highest system efficiency and production for a solar panel over 300 watts. SolarWorld only delivers modules that have greater than or equal to the nameplate rated power. This means you get at least 340 watts of power, and as much 345 watts, with the power tolerance ranges between -0 Wp and +5 Wp. More for your money in a 300 watt solar panel range, the SolarWorld SW 340 is a great panel to build a powerful system for your home or business.

    High-quality, high performance, and high reliability – the SolarWorld Sunmodule is designed and built for long-term yield stability and ease of use. Every module is factory flashed at standard test conditions (STC) to determine the power output and then sorted in 5 watt increments. Only modules with a flashed power that is greater than or equal to the nameplate rated power are delivered. Flash report data is provided with every order.

    The patented box channel frame design provides extraordinary stiffness in bending and torsion. The laminate with 4mm glass is set deep in the frame channel and secured with precision applied adhesive. The frame is assembled by press fit to maximize strength and longevity. The result is an extremely robust package that can be mounted in any orientation and can withstand static loads of up to 113 psf.

    SolarWorld provides a 10-year Limited Product Warranty and 25-year Linear Service Warranty*.
    *See warranty statement in the 'Documents' section above for details.
