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 -
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 -

La prossima volta una prolunga fino alla lavatrice dei vicini!
-
What happens if you don't use it? It goes to waste? Or does the system get damaged somehow?
-
@GustavinoBevilacqua tecnicamente se ci abilitano per rimandare in rete è praticamente una prolunga per arrivare dai vicini, giusto? :D -
@float13 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)
-
Esatto!
Una reticella…
Oppure potresti offrire ricariche alle auto elettriche in cambio di prodotti dell'orto… -
@GustavinoBevilacqua oggi sono andati sprecati circa 200 Wh, su 19kWh fatti, eh, non è che sia una cosa significativa :) -

@valhalla domanda sciocca, cosa succede all'eletricitá in eccesso? si surriscalda qualcosa? O si manda in grid a gratis?
-
@Mr_GHARice @mdione @float13 @srtcd424 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.
-
@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.

@alorenzi magic :D
i pannelli non producono oltre quanto viene richiesto dai carichi
(suppongo ci sia un po' di calore in più da qualche parte, visto che il sole ha colpito la superficie, ma non a sufficienza da causare problemi)
-
@mdione @srtcd424 @Mr_GHARice @float13 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)
-
@srtcd424 @float13 @mdione 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)

@cate @mdione @float13 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

@valhalla i can recommend vacuuming the house or baking cake/casserole?
For the advanced users: Charging the EV or Water heating via heatpump
