Solar panels are much more efficient in space (no atmosphere).
Before downvoting, would you mind quoting the relative cost of batteries vs. solar panels for a 150kW solar-powered satellite?

Batteries are expensive.
Marginal cost of launches keep coming down for SpaceX with reusable rockets and lifetime of satellites is long.
