I disagree with the obsolete aspect. Just because a "newer" model has come out, doesn't mean your panels stop working. Also the technology usually revolves around making the panels smaller or cutting the cost of manufacturing..
This means if you have a 250w panel, a newer 250w panel will still put out the same amount of power (ie it's still 250w). It's just more likely that the new panels will produce that power in a smaller package and will probably be cheaper over time.
