The amount of light is not a factor in germination. Any shady location will do, as long as the requirements of temperature and moisture can be maintained. The temptation to locate your seeds in the sun should be avoided. While this will give you the needed high temperatures, drying out will be inevitable. Remember, seeds which fall from the parent tree in nature normally germinate in shady locations.
Palms are well-known for their erratic behavior in germinating.
Some take weeks to show any sign of sprouting. Different species will give different results. But follow the guidelines above, be patient, and the sequence of cues generated internally from the embryo and externally from the seed environment will result eventually in a majestic palm.
