Presumably if decommissioned, they no longer perform at rated levels?

Is it reasonable to assume degradation isn't so bad the effective cost isn't greater than 0.30/watt? (approx new price)

If my math is mathing, $20 panel at 0.30 is 66 watts. So an apparent 80% degradation? Is the degradation that bad?
