Hi, Looking at a solar blanket for a boat and at times would want to have it inside a large windscreen (Clear) which faces the sun throughout most of the day to top up my batteries and was wondering what losses in terms of efficiency I would have inside the window vs external?

If all that you are looking for is enough to maintain your battery while in storage then yes it should be fine.

On our old van I used a small 5W panel sitting in the vans skylight to keep the battery fully charged, worked a treat.

.
I have seen a test of a small (~10W) PV panel which resulted in less than 10% loss when placed behind an automotive windscreen.
