Review: THEY DO WORK! - I was hesitant to buy these for fear they wouldn't work as promised. But they actually do work great! They work just as well as the Renogy brand 550w panels, for a lot less money. Generator pic is of two 550w panels and was taken on April 20th, on a sunny day in Fort Lauderdale. By mid May, these will easily be pulling 550w each. Rooftop pic is 1 Renogy panel and 3 of these. That's why one looks different. They arrived undamaged and about a week sooner than expected. I would absolutely buy these again. ## Features - 【Bifacial Solar Panel】The 405 watt solar panel use high-performance monocrystalline solar cells, which can provide up to 21% higher efficiency sufficient light conditions.
