For use in a private scientific project I'm researching how long a
small earth orbiting satellite will operate. The satellite's
electronics needs to generate for over 30 seconds 15 watts of power
each day.

Overdesign for capacity to reduce effects of age induced degradation and
use a solar cell and capacitor bank. You only need 30 seconds per day and
this would be the lightest and cheapest long-term solution. Many
applictions are using so-called super capacitors for short duration
rechargable power.
