An analemmatic dial is not a nice choice for that latitude. You can find a lay-out for 15 deg. latitude at my website: www.biol.rug.nl/maes/sundials/ Click "Analemmatic - extra info" in the main menu and select "The shape at different latitudes". As you can see, reading the time is difficult around noon during the summer half-year, and in early morning and late afternoon during the entire year. Have you considered an "inverted" armillary sphere? Examples can be found at my page "Pole-style - equatorial" in the bottom row of thumbnails. Please keep us informed about the results!
