Quick Overview

Made in the USA

The SolarWorld SW 255 solar panel is a monocrystalline solar panel intended for grid-tie solar power systems. Solar World SW 255 solar panels are made in the USA and are manufactured to the highest standards of quality, performance and durability.

Their performance warranty includes "plus-sorting" ensuring your SolarWorld solar panels produce the same or up to 5% better than the rated wattage.

World-Class Quality

SolarWorld products are manufactured in state-of-the-art factories according to strict German and US quality, labor and environmental standards.

Award-winning products

SolarWorld modules were ranked number one in two consecutive tests carried out by the Photon trade magazine in 2008 and 2009 with up to 12% more yield.

SolarWorld Plus-Sorting

Plus-Sorting guarantees the highest efficiency of the installation. SolarWorld only delivers modules that have greater than or equal to the nameplate rated power.

25-year Linear Performance Guarantee*

SolarWorld guarantees, over 25 years, that the modules' performance will not decrease by more than 0.7% per year - a distinct added value compared to the two-tiered guarantees usual in the industry.
