Maybe not - the additional weight (maybe asditional fuel pellets) could be offset by the benefits, mars-side. E.g. If it can be integrated into the lander component, it can power a settlement or some experiments, at the very least. If left in orbit, it can also power a medium/ long term communications satellite for a while too.
Sounds a bit overkill to make the “continuous power supply for at least 10 years” if your trip is just 6 weeks.
