Dave, I removed the ridged panels to reduce weight and to try flexible panels. Last year I went with a new version of Renogy 160 watt panels that did not even make it a year. Two failed with in 9 months. Mounting was according to manufacturer specifications and the panels seemed very durabl, certainly enough to last for years, but formed corrosion marks at several points along the bus bars. If I go back with flexible, I may go with the shingle style recommended by rickst29 or more likely CIGS panels like the 80 watt panels from richsolar. They are pricey for the wattage, but meet mil specs and are one of the most durable flex panels on the market. They also happen to fit the roof space on the back shell of my 3124 perfectly. These panels went for more than $1000/ea only a couple years ago. Hoping to see another price drop before I need them.
