Maybe he's not using the same sun that we're using.
Portable solar panel. In fact, I think it's the only portable 400W. Portable means not glass based by the way. Well 400 that aren't 3 times the sq feet and really get sub 300.
roll outs are cool and cheap. but they don't get anything near what they advertise like these do.
Nothing wrong with roll outs...but buy a lot..you will need them to hit 400+.
or just pay the premium here (about 20-30 percent) and get 370+ on a sunny day with one panel, taking up less space.
I had bought this last year. Didn't have a chance to use it too much but it does work.

After using the $60 off coupon it comes to $150.
Ecoflow is now selling 220W Bifacial Solar Panel Kit for only $332 each if buy 4 or more.
They are Bifacial Solar Panel which has a better efficiency and the 220 wattage matches better with the River Pro which has max 200w input.

US average cost is 14.92 cents per KWh [eia.gov] (May 2022)
Ignoring taxes, shipping, installation costs, maintenance, batteries, etc, and assuming you're getting 100% efficiency on electricity generation the calculation looks like this:
(Cost of panel) / 0.1492 = KWhForBreakEven
110 Watt panel cost is $209.
$209/0.1492 = 1400.8 KWh generated to break even
Since the panel generates 110 watt hours maximum, that's 0.11 KWh, so you need 12,734 hours of runtime at 100% efficiency.
If you get an average of 4 hours per day where you hit the maximum, that's (12734/4), or 3183.5 days to generate the electricity to save $209. That's 8.72 years.
YMMV, take it with a grain of salt. Hawaii, with 43.11 cents/KWh, it's a different calculation. $209/.4311 = 484.8 KWh, or 4,400 hours at 100% efficiency, at 4 hours per day, that's 1100 days, or 3.01 years.
Take it all with big grains of salt, since you're not likely to get 100% efficiency, and these panels aren't really intended for daily residential use.

4x 12v 200ah amperetime lipo4 off amazon in series for 48v
Growatt 3kw 48v all in one inverter charger
4 various portable generators from 1kw to 3800w for the worst of winter in oregon when solar is nonexistant.
This is enough to run everything I have including 77" sony oled and two aiyima a07 stereo amps and 4 giant tower speakers and fridge and laptop and lights and internet and phone and cable modem and wifi and charge my ebikes and rc toys and run all the tools I need to fix up my fixer house. 4 panels easily supports all this in the summer, I'm going to need to get all of them hooked up and maybe that will work in winter.
