panel is the correct dimensions, packaged well and arived undamaged. However, the panel had some sort of glue residue all over the backside of the panel (maybe from manufacturing, or packaging) there also were some scuffs and scratches on the backing sheet. I dont think this should effect the performance of the panel. testing it out in full sun i was seeing power, realistically due to its size this is a 220-250 watt panel, I doubt execpt for under the most perfect circumstances you would ever see 300 watts from this panel. I.e. maybe at the equator during full sun.)
