The only reason why I mentioned the brand, is because most of their battery systems have the yellow solar port - so you can plug solar directly into the system, some have two ports. They also have built-in inverters, so you can plug the laptop directly into that. There are probably other brands that offer a similar setup.

If your laptop can be powered by USB-C, even better. If the battery system doesn't have usb-c output, buy a GaN charger (mine is a 140W GaN charger and its amazing). They are super efficient and don't generate much heat.

Fixed-installs (or grid tie-in) requires electricians and sometimes rewiring some parts of your home's circuitry. Huge operation if done right but generally not needed if you only have one or two panels and a portable battery system.

There are very good benchmarks on youtube with the portable solar + battery setups.
