Sunmodule Plus SW 300 Mono 5BB, Silver Frame
300 Watt Monocrystalline Solar Panel - 5 busbar

The new SolarWorld Sunmodule SW 300 Watt (33 mm frame) 60-cell solar panels now come with 5 busbars (vs. 3). See our BLOG on why this means more power for you!

Did you know SolarWorld solar panels are plus-sorted by testing each solar panel as they come off the manufacturing line? They are rounded down to the nearest 5 watt increment. So a 300W panel could be anywhere from 300W to 304.9 watts. This ensures you are getting the highest system efficiency and saves you the time the time-consuming chore of sorting the solar panels at the job site.

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 on a standard two-rail mounting system.

SolarWorld provides a 10-year Limited Product Warranty and 25-year Linear Service Warranty*.

    * Max Reverse Current of this module is 25A. Reverse current is used for calculations and sizing of fuses and breakers. This is subjective - as this can be calculated based on 80% of the max, or 90% of the max etc. Therefore depending on how the fuses/breakers are sized, this module can handle a maximum of 25A of reverse current.


    **Frame compatible with both "Top-Down" and "Bottom" mounting methods. Grounding locations - 4 locations along the length of the module in the extended flange.
