How Tough are Our Solar Panels? Jeff August 25, 2010 All, DIY 1 Comment If you’re curious about whether the our small solar panels can take a beating, watch this video of our 2 Watt solar panel below. We use industrial materials for the backing of each panel and don’t skimp on the coating material (which is a fair amount of the total cost). Chances are you’ve seen solar panels that have yellowed or cracked over time. Think of these at the opposite to those panels. We’ve left panels like these out for years and they’re still producing near their spec and looking great.
