My biggest use of electricity is my laptop and monitor.
Any ideas on a portable solar panel that could power those during the summer? Portable because I rent and can’t fix anything down, it doesn’t have to fit in a backpack or anything like that.

That being said, there’s a lot of options nowadays which is exciting! For instance, you could have a 200W port panel and a 1kWh battery system from eco flow that should run both with room to spare. Anker has a new system meant for patios but it’s only for Europe.
Just 75W.
Specifically 1 Watt-hour==3600 Joules.
kWh is obviously inconsistent with SI conventions if commonly used; but 'kW⋅h' or 'kW h' is completely acceptable. As is 'W⋅h'
A full list of acceptable non-SI units can be found in the brochure here under: "Non-SI units accepted for use with the SI units"
If you want to run a line into your house you can get by with one, or just get a panel with a usbc pd output.
For almost all people they are only appropriate when you are off-grid.
Personally I'm interested in a DIY mod to add solar panels directly to the back of a laptop screen. It probably wouldn't be able to actually charge unless the machine is in sleep mode (which also would have the lid closed which would help), but it would extend the battery - if the machine averages 10W and the panel gives 1W, that's an extra 10% runtime for free, and better if it sleeps in the middle (which works, because I'm unlikely to use a laptop continuously for 10 hours).
Or environmentally sustainable?
A solar panel has life-span of 25-30 years, will you be utilizing that? or are you just creating more waste?
If you wanted to protect the environment, it's probably better to find a wind-farm project or solar farm project to invest in.
It's really easy to think that adding solar panels everywhere is a good idea; but you might just be making e-waste.
(The range at the local big appliance retailer is about 35W for the cheapest models to 10W for the most expensive.)
