Solar panel

I found the page which advises you about which solar panel you should purchase based on your environment. The page calls them super solar panels, and there is a 2W and a 5W. But when searching the products, I only find one item, simply called the solar panel. I'm confused. Is there more than one for sale? I am in a sunny environment, but have many motion detections each day. The chart makes me think I need the 5W. There doesn't seem to be more than one solar panel for sale
