Am i right in saying, it is the hops in a beer stored in a clear bottle, that are effected by the the light to cause the off flavours?

Reason I am asking is that I buy hop pellets in clear vacuum packaging so why don't they suffer the same fate?

Its not just the clear bottles issue, these bottles then need to be exposed to sunlight for extended periods. Its this combination that causes skunking. Your hops in clear bags are probably kept in an enclosed box or fridge and so are out of sight of sunlight, and I suspect that the hops would also need to be wet to allow the enzymic reaction to start.

It's the act of fermentation as well I believe, as an unfermented beer wort left in the sun will not skunk.

It's the iso-alpha acids that are prone to the skunking reaction, and they are formed during the boil.
