I have two 30 watt panels on the roof of my trailer, each is hooked through a battery tender solar charge controller.
One charges my trailer battery which runs the 12v lights, winch, radio, and computer. The other charges the race car. I rarely ever use a regular battery charger because the solar charger does such a good job.
I think a solar maintainer will work perfect in your situation. 5 or 10 watts should do the trick. The winch gets used infrequently and the maintainer will have a long time to keep the battery topped off.

I’m not sure how your battery life is now, but you should look at getting the correct DC plugs for your laptop and weather station and powering them directly off the battery. The laptop and weather station run off of DC so the way you’re doing it now is converting DC to AC with the inverter, then the power supply for the devices is switching the AC back to DC. Those conversions waste energy.
You can look at a car charger that plugs in to a cigarette lighter jack for the laptop. The weather station probably has the DC voltage stamped right by the plug, so you’d just need to measure the plug then go online and find the right adapter cord, likely 12v to 5v.
