What do solar panels do on boosters?

[Vovxb]

Why do people put solar panels on rocket boosters? is it like a grid fin or an rcs thruster?

It's a form of aerobrake. It's draggy as hell when extended, and can be folded easily.

 

[Vovxb]

Landing legs look better though.

 

[Vovxb]

well before 1.5 we can use it as landin legs right?

but for me the SS is usually for power and grid fin-ish
