RV Solar Panel

Kind new to the solar panel, any idea?
I have a small TT, one person with 2 dogs, full-time RVer.
Located in MA, somehow raining a lot in summer and snow in winter.
I read some posts online shows different watt, how much do I really need? Absolutely run AC in summer. Any brand suggestion?

Thanks in advance.

    Do an energy survey to determine your normal amp hour use. Multiply by 1.5. Outfit your TT with at least twice that number of AH battery capacity. Normally you’ll need one solar watt for each battery AH. You might need 1.25 or 1.5. Buy a charge controller with adequate capacity. I recommend a MPPT model. Don’t cheapout on wire size. Within reason bigger is better. But solar isn’t going to power your AC.
