Sunmodule Plus SW 280 Mono/ Version 4.0 (33 mm frame)
280 Watt Monocrystalline Solar Panel

SolarWorld's Sunmodule SW 280 V4 (33 mm frame) 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 280W panel could be anywhere from 280W to 284.9 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. SolarWorld's US factories have a fully automated production process that creates a consistently high quality solar panel. The SolarWorld Sunmodule is designed and built for high quality, high performance, and high reliability.

SolarWorld's new V4 box channel frame is patented and provides extraordinary stiffness in bending and torsion. The 4mm low iron tempered glass is set deep in the in the aluminum frame channel and is secured with precision applied adhesive. THe resulting product is an extremely robust panel that can be mounted in any orientation, portrait or landscape, and can withstand static loads of up to 113 psf.

SolarWorld 10-year Limited Product Warranty and 25-year Linear Service Warranty ensures a long, reliable product life*.
*See warranty statement in the 'Documents' section above for details.

    * Max Reverse Current of this module is 26A. 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.
