Balcony solar panels can save 30% on a typical household’s electricity bill and, with vertical surface area in cities larger than roof space, the appeal is clear
While the panels are important, the main reason why its important to also have the battery component is because most people tend to work when daylight is out (where the house is theoretically using up the least amount of power) thus, if one didn’t have a battery, its pushing the power back into the grid. At the same time, power usage tends to spike when it gets closer to night, where solar is ineffective, and relies thus back on the grid if there’s no battery. While personally(not the original person) would never claim it does essentially nothing, the battery component is extremely critical for energy independence as the time period people want to minimize grid usage the most should be during the peak hours, which inconveniently is when the sun is down.
These units do not push electricity into the grid unless their fail-saves are bypassed deliberately or fail catastrophically.
Anyway, no, it’s not that important. You already have a battery at home- your entire home. If you’re overproducing electricity then you can convert it to another medium such as hot or cold air depending on the time of year and save on AC. You can run preload your washer and make it run when production is at peak automatically. Be creative. Most people will not be overproducing electricity with one of these kits.
Additionally, local energy independence is not about being off-grid, it’s about being able to charge and use a radio or the internet in an emergency where the grid is out. A solar panel on the balcony provides that, it makes you independent of the grid even if you’re still using the grid to run your washing machine and the oven in a non-emergency scenario. A battery will only be a boon to you if you expect the grid to go out for days at a time regularly or if your kit is large enough to actually overproduce at any point, which again, most don’t; they supplement.

I don’t understand what you mean by this. The time people want to minimize their grid usage is during the hours of 16-19 which is peak usage and when electricity is most expensive. These panels will still provide a decent supplement in that time during the summer half of the year.
In summary, I just don’t think a battery is going to add much unless you’re expecting to overproduce regularly which a balcony panel isn’t gonna do.
edit: I should mention that the larger kits do come with battery options, because those could be expected to overproduce, and thus would be useful.
Do you know how these kits work? The whole point is that they’re plug-and-play. If the feed back into the grid, they are not plug and play and will require coordination with your power company lest you accidentally kill someone because you’re backfeeding into a line they turned off so they could work on it.
The kits have built-in measures to avoid backfeeding, or they would be illegal. Where I live, they’ve been deemed so unsafe, failsafe or not, that you’re just not allowed to use them.
These kits absolutely can push power into the grid, usually with payment for the generation. Just because they may not be allowed where you live doesn’t mean they don’t exist.

the suns only up during that time period over the summer. during other parts of the year, it’s only partially up. If you have to go for a specific time of the year in order to fix a problem, then it hasn’t fixed much of the problem if it only addresses 1/4 seasons. solar is often not that strong during peak usage. It’s basically effective if you have a lot of appliances at home that are timed specifically to run when most people are away, which is the part that you have to train an audience to do.

What are you talking about? Of course, energy that isn’t used in the household is pushed back to the grid.
No, that’s not how it works in the general case. There are ways to setup a house to back power but it’s more complicated than just plugging it in.
Without proper safeties in place back flowing power to the grid becomes extremely dangerous for line technicians
