TIL that #solarPanels also have bad consequences :D
today just after lunch for the second time since they had been installed our batteries were basically full, the sun was still shining, and we still can't send energy to the grid¹, so we run a dishwasher load, a washing machine (cold water, so it didn't help a lot, but that's what I had to wash at the moment) and we still weren't using what the panels were producing, so I had to face The Pile of Stuff That Needs Ironing.
I had been successfully² postponing that for *weeks*!
¹ from installation to being enabled for that it usually takes a couple of months, between bureaucracy and waiting for a tecnicians
² not that it is in any way near the bottom

Modern¹ Italy had two queens and a bit.
The third one was only queen for a few months and then we got rid of the whole thing.
The second one, Elena, whose husband was busy making sure that Italy would become a republic soon², devoted herself to charitable work. I don't think it makes her especially worth of merit, but if you are stuck as a woman born in a royal house in the 1800s and are a baseline good person, that's one of the things you do.
The first one, Margerita, was a reactionary asshole who encouraged the shooting of protestors and was an enthusiastic supporter of fascism.
Guess which one is being celebrated with a stamp this year?
¹ there was a kingdom of Italy in the middle ages, but that's a different matter
² this may have not been his aim

Ci tengo a segnalare che oggi #trenord ha annunciato *per tempo* che un treno già presente al binario sarebbe partito prima di quello in arrivo (in ritardo) ad un altro binario, nonostante l'orario dicesse il contrario.
Credo anche con abbastanza preavviso per prendere gli ascensori per il cambio binario!

A Day Off
Posted on February 3, 2026
Tags: madeof:atoms, madeof:bits
Today I had a day off. Some of it went great. Some less so.
I woke up, went out to pay our tribute to NotOurCat, and it was snowing! yay! And I had a day off, so if it had snowed enough that shovelling was needed, I had time to do it (it didn’t, it started to rain soon afterwards, but still, YAY snow!).
Then I had breakfast, with the fruit rye bread I had baked yesterday, and I treated myself to some of the strong Irish tea I have left, instead of the milder ones I want to finish before buying more of the Irish.
And then, I bought myself a fancy new expensive fountain pen. One that costs 16€! more than three times as much as my usual ones! I hope it will work as well, but I’m quite confident it should. I’ll find out when it arrives from Germany (together with a few ink samples that will result in a future blog post with some SCIENCE).
I decided to try and use bank transfers instead of my visa debit card when buying from online shops that give the option to do so: it’s a tiny bit more effort, but it means I’m paying 0.25€ to my bank1rather than the seller having to pay some unknown amount to an US based payment provider. Unluckily, the fountain pen website offered a huge number of payment methods, but not bank transfers. sigh.
And then, I could start working a bit on the connecting wires for the LED strips for our living room: I soldered two pieces, six wires each (it’s one RGB strip, 4 pins, and a warm white one requiring two more), then did a bit of tests, including writing some micropython code to add a test mode that lights up each colour in sequence, and the morning was almost gone. For some reason this project, as simple as it is, is taking forever. But it is showing progress.
There was a break, when the postman delivered a package of chemicals2 for a future project or two. There will be blog posts!
After lunch I spent some time finishing eyelets on the outfit I wanted to wear this evening, as I had not been able to finish it during fosdem. This one will result in two blog posts!
Meanwhile, in the morning I didn’t remember the name of the program I used to load software on micropython boards such as the one that will control the LED strips (that’s thonny), and while searching for it in the documentation, I found that there is also a command line program I can use, mpremote, and that’s a much better fit for my preferences!
I mentioned it in an xmpp room full of nerds, and one of them mentioned that he could try it on his Inkplate, when he had time, and I was nerd-sniped into trying it on mine, which had been sitting unused showing the temperatures in our old house on the last day it spent there and needs to be updated for the sensors in the new house.
And that lead to the writing of some notes on how to set it up from the command line(good), and to the opening on one upstream issue(bad), because I have an old model, and the board-specific library isn’t working. at all.
And that’s when I realized that it was 17:00, I still had to cook the bread I had been working on since yesterday evening (ciabatta, one of my favourites, but it needs almost one hour in the oven), the outfit I wanted to wear in the evening was still not wearable, the table needed cleaning and some panicking was due. Thankfully, my mother was cooking dinner, so I didn’t have to do that too.
I turned the oven on, sewed the shoulder seams of the bodice while spraying water on the bread every 5 minutes, and then while it was cooking on its own, started to attach a closure to the skirt, decided that a safety pin was a perfectly reasonable closure for the first day an outfit is worn, took care of the table, took care of the bread, used some twine to close the bodice, because I still haven’t worked out what to use for laces, realized my bodkin is still misplaced, used a longand sharp and big needle meant for sewing mattresses instead of a bodkin, managed not to stab myself, and less than half an hour late we could have dinner.
There was bread, there was Swedish crispbread, there were spreads (tuna, and beans), and vegetables, and then there was the cake that caused my mother to panic when she added her last honey to the milk and it curdled (my SO and I tried it, it had no odd taste, we decided it could be used) and it was good, although I had to get a second slice just to be 100% sure of it.
And now I’m exhausted, and I’ve only done half of the things I had planned to do, but I’d still say I’ve had quite a good day.

in reply to Elena ``of Valhalla'' • •Oggi ho scoperto che i #pannelliSolari hanno anche delle conseguenze negative :D
per la seconda volta da quando ce li hanno installati, dopo pranzo le batterie erano quasi piene, il sole stava ancora splendendo e non possiamo ancora rimandare energia in rete¹, quindi abbiamo fatto partire la lavastoviglie, la lavatrice (a freddo, perché quello avevo da lavare, quindi non ha aiutato molto) e ancora non stavamo usando quello che i pannelli stavano producendo, e quindi ho dovuto affrontare La Pila Delle Cose Da Stirare.
Ero riuscita a procrastinare la cosa con successo² per *settimane*!
¹ di solito ci vogliono un paio di mesi
² non che io sia arrivata anche solo vicina alla fine

in reply to I am Jack's Found 404 • •@I am Jack's Found 404 it goes to waste
and as soon as the technician will change our meter (which should be soon) it will go back to the grid (and we will get paid a small amount)

in reply to Elena ``of Valhalla'' • • •@float13 I wonder where that energy goes. Heat I guess? Or is it not generated in ths first place? Do pannels get hotter in that case?

in reply to Steven Reed • • •Edit: that's why the system needs to be cut off from the grid or shut down in case of power outage in the grid.
@mdione @valhalla @float13
Elena ``of Valhalla''
in reply to Gid • •@Gid @Marcos Dione @I am Jack's Found 404 @Steven Reed there is a bit in the inverter box that decides whether to recharge the batteries, deliver energy to the hourse or send it back to the grid, and it had been setup not to deliver energy to the grid, until the meter is ready for it
otherwise, the meter would have happily registered it as energy passing through it, and billed us for it
it's not the system that shuts everything down when there is a power outage, as there often is a trickle of energy going up into the grid according to the monitoring system, enough to be dangerous for people working on the outage, but not significant for billing reasons.
Marcos Dione
in reply to Gid • • •@Mr_GHARice I think you're answering a different question, that of "what happens if the main grid generators go down (f.i., disconnected from the grid) and the solar panel is still connected". My question was "what happens if there is no load", and similarly, "who actually provides the energy if there is load, solar vs grid; and what happens to what is generated but not used". On the grid side it's regulated by generating more or less energy depending on load.
@srtcd424 @valhalla @float13
Elena ``of Valhalla''
in reply to Marcos Dione • •@Marcos Dione @Steven Reed @Gid @I am Jack's Found 404 the smart bit inside the inverter box decides how much energy should be taken by the panels, batteries or grid, and how much energy should go to the house, batteries, or grid
the panels are ok with only providing less energy than they could produce, with no ill effects, because electovoltaics are *magic*; (I assume that there is a bit more heat going around, but still less than what would have been released by the sun hitting a dark-ish roof, so easily dissipated)
Elena ``of Valhalla''
in reply to Steven Reed • •@Steven Reed @I am Jack's Found 404 @Marcos Dione indeed, in both safety and ability to scale down photovoltaics are much better than wind turbines
(which is why wind turbines are mostly a power plant level thing, while photovoltaic on the home is often a better choice even in places with more wind than sun)
(also, this is definitely a case of whyNotBoth, each in its own suitable environment)

in reply to Marcos Dione • • •@mdione @float13 it is not generated, so it becomes like a dark wall (so still absorbing heat, but no photo-electric-effect in place).
@valhalla luckily we are in winter, else you should iron and solder and weld all days.
Elena ``of Valhalla''
in reply to cate • •@cate @Marcos Dione @I am Jack's Found 404 our soldering iron is something like 20W, basically irrelevant
and I don't have a welder, nor can use it (yet)
I suspect that the clothes iron isn't that much of a load either, at least once it's up to temperature, because it's rated 2.2 kW or something, but it's also on for very short periods of time, I should take some actual measurement
the same applies to the kettle: rated 2.2 kW, but for a tea it only stays on for a couple of minutes, so it's less than 100 Wh

in reply to tk • •@tk honestly, ironing clothes is less of a chore than vacuuming :D (we usually do it a bit at a time with a rechargeable vacuum)
(and baking, considering a number of food restrictions, would have required too much prep time, ending up happening after the peak of electricity production)
(heat pumps for water heating have been postponed to “when we can save a bit more money for it, and hopefully the prices will have gone down a bit, because right now all of the quotes we're getting are (probably oversized but) extortionate”)
Elena ``of Valhalla''
in reply to Elena ``of Valhalla'' • •@tk (water heating was / is integrated with heating water for the radiators, and changing *that* would have required too much work and expense. the quote for an air-water heat pump were, as I said, extortionate, so we added air-air heat pumps, but they are sized to work *together* with the radiators, not instead of them)
(one day we'll have a fully electric house, but it will need to happen through gradual changes)
(and yesterday, since the sun was shining and there was some warm wind, it was a bit too warm to turn on the heating anyway)

in reply to tk • • •Elena ``of Valhalla''
in reply to tk • •@tk here the quote was for about 25k€, plus an unknown expense to change the electrical wiring to get three-phase current, plus having to pay more for electricity (because three-phase) and not being able to afford solar panels for years
or we could start with the solar panels and start saving money on electricity and save it for more electrification later
it wasn't a hard choice :)
