I have a 275SD and while the hard tops are not the same but the usable space may be similar because I have two skylights down the center. I'm not sure of your battery situation and what your objecyives are but I can tell you what I did recently.
I upgraded my batteries from two Interstate Group 24 Sealed Wet batteries to two Duracell Group 27 AGM 100Ah Marine batteries with a little more capacity. I'm rack storing my boat so I won't have regular access to AC so I decided to install a solar system to keep my batteries charged.
I went with a new style Renogy 100W Flexible Panel....

I also went with a Renogy 30A PWM Controller (I had this from another project otherwise a 10A would have been fine plus it allows for expandability).....

I used 3M VHB Tape to secure the panel to the hard top and it did a very good job securing the panel....

I figured the 100W should be enough to keep my batteries maintained when the boat is not in use and help the house battery from being drained too quickly when floating with the stereo on.
