Cost per actual watt is still lower for the Renogy. I'd also trust Renogy more than Harbor Freight.

I'm not advertising here and just found some random link to show you. Portable solar panels normally offer the adapters along with it and are foldable, much easier to carry around and even have legs for tilt.

Your buddy should look to see if the power company have a battery on demand program.
In Connecticut we have a program called connected solutions. Which draws our battery down to 20% per event in the summer. They cut us a check for 1500$/year for using two of our batteries. That could help his ROI faster.

It won't run anything.

If he got solar on every square inch of his roof then they generating plenty of power and storage for when there are no sunlight.
Maybe he has 10 oak trees surrounding his house ?
If you are near power don't waste your money on Solar panel and battery thinking it will save you money. You can maybe get 1kw of energy for 2+ days of direct sunlight on a flat roof with this 100watt solar panel. 1kw is just an average of cost of .18 cents of energy produce by home electricity.
So with installation and other equipment, maybe break even in about 10+ years which seems pretty much the ballpark of the worst estimates I've seen for solar installations. With the rising costs of electricity, some people are looking at breaking even a couple years earlier than planned. e.g. you're facing $0.50 / kWH in CA. For the northern states, probably closer to 20 years or so from the climate. Still within useable lifespan of a panel.
So yeah, solar will save you money assuming you get good sun coverage, your house doesn't blow away in a hurricane or burn down in a fire, and you don't get taken for a ride by a fly by night installer. Most of that are also the same risks you take with owning a home. Otherwise, solar would be little more than a money pit.
It's pretty much the same calculus as renting vs owning a home. For most people, if you can swing enough for a solid down payment, owning saves money. Assuming the house doesn't burn down. For the rest, if you're constantly on the move, barely sleep at home, live alone with no family or roommates, etc, renting can work out cheaper.
