Boniface,
Ah, Dr. No, you are adding a bomb shelter to your tropical island hideout! Good idea!
If you are an off-grid survivalist, you can hook up a ventilating fan to a stationary bicycle. That is a very dependable bomb-shelter method of ventilation.
Otherwise, you'll need a battery bank to handle the fans on cloudy days and nights. You'll need to size your PV array and battery bank according to conventional off-grid sizing guidelines. And you'll need to size your mechanical ventilation system according to ASHRAE 62.2 guidelines (7.5 cfm per occupant, plus 1 cfm for every 100 square feet of occupiable floor area ).
