And by jibsheets. Make sure that your panels won't get in the way of your sheets, on any point of sail, during tacks and jibes, when the sheets are flogging, etc. If you fly a spinnaker check that as well (these sheets and guys are often led differently than jibsheets).

I would use the basic rule of thumb as posted aboveto decide what size of panels to buy, then do as much as I can to optimize output. Any extra power I get is a bonus.
