By EU standards, that is expensive and low power for balcony power. It this US regulatory capture, China import rates, something else, all of the above?

It might have to do with our 120V electrical standard. I know our kitchen kettles and irons are lower wattage than European ones.

I miss how fast our German kettle heated water :-(

So that's what an old-school infomercial translated to the Web looks like: "We pass the savings onto you! [Just pay $29/year membership fee!]" (Seriously, though. 180W? That's not a ton of "help" for a typical refrigerator that draws anywhere between 300 and 800W.) (Also, seriously, though. Most apartment owners and condo HOAs won't allow their residents to put these on their balconies.)

Most places restrict HOAs and apartment owners from ridiculous rules.

For example, Utah, which was a balcony solar pioneer:

Can confirm, setup a couple hundred watts as a hobby project during the pandemic and built a battery pack - the biggest challenge (other than matching connectors) is finding anything other than just "charging devices" that the thing is practical for - until you get up around 1000W a lot of "normal" stuff is just too hungry.

This just plugs into an outlet and offsets whatever usage you have, though. No need for a battery or matching load. It just subtracts 180 watts from your household usage.

These types of devices are fairly popular in Germany, and maybe other places. For someone like me, with very high peak daytime prices, even a small offset would be valuable, but the full price here seems to be $500, which is too much. No reason it couldn't be much cheaper, though.

Just for comparison buying solar panels off craigslist is about $0.20/watt.

Can you just plug the panel into an outlet?

Obviously not, but since the panels are >8x cheaper it's possible to buy 2x the capacity advertised here + an inverter for a one time cost of $200, so about $0.33/watt.
