Wish these kind of panels were available at that price here. We have pretty much 12 hours of sunlight every single day but household solar panel is discouraged by the state owned utilities.
You'd need rather more panels (and/or some combination with batteries) to hit 900W output constantly. (on the other hand, do you need 900W constantly, or is that peak usage? A battery might be able to handle that.) That said, solar panels are probably a lot more efficient in Indonesia than they are in Germany. Since you're in/near the tropics, perhaps 1500-2000W nameplate capacity could cover your 900W? See if you can get a local expert do the maths for you.
Germany is definitely not one of those zones
As a data point, 200-300W is enough to heat a 35m2 wooden house to 20°C with a heat pump, in Poland, so with external temperatures normally between -5°C and 15°C.
Your watts can go much farther than you think.
If anything, I'd expect the prices to be lower. Do you have a local Indonesian equivalent of eBay like we do here in Argentina? Or, just eBay?
I assume "electricity capacity of 900W" means that the wires from the transformer (and in the walls) are only rated for 4 amps at 230VAC. This means that you can't really run a 2000-watt air conditioner at all. Whereas, with an 800-watt solar panel charging a battery, you can run a 2000-watt air conditioner 40% of the time when the panel is in full sun. Washing machines and refrigerators are an even bigger difference, since they usually have huge peaks of current draw when they start up their motors, but relatively low average power. So the solar panels may actually be a much bigger boon than simply comparing 800 to 900 makes it sound like. A single car battery can typically source 6000 watts for brief periods of time.
The state's power company seems to stop approving grid-connected solar panel system due to oversupply. It's fine if it's not connected to the grid.
I would have thought that the issue is purchasing power inequality between germany and indonesia, not that they're not available globally at a similar price
Yes, there is inequality as can be seen in Pakistan. But once restrictions are dropped the solar panels take off.
I'm also not sure if this fits with the price restriction they mentioned. Prohibitions can't be bypassed by paying a higher price, unless it were to refer to bribes
They're hooked up in an extremely safe and responsible manner, but it's understandable that there are regulations about what can be hooked up, and simply not surprising that they haven't been updated to say "yeah, this is ok".
It's also possible to have a solar system that doesn't do this. Either you have a battery system and if you generate excess power you only put it into your own batteries or the system is small relative to the load of the house so you're rarely if ever generating more than you're actively using and configure the system so the grid is only ever attached to the input side. This should not be any more dangerous to the grid than using a UPS or charging an electric car and if the regulations make it more difficult than that they should be suspected of malicious intent.
They do so responsibly (fancy electronics that turn them off when the grid goes down). But it is the case where you are acknowledging that extra regulatory criteria make sense.
Analogously, you might reckon that the best place for a nickel mine would be on 16 Psyche, because that's where the largest surface nickel deposits are. Or you might reckon that it would be good for an interpreter to give an error when the user attempts to run an infinite loop. But, lacking an interplanetary spaceship or a solution to the Halting Problem, these calculations are of little value.
The most effective response I've found to regulations that harm me is to leave.
The word "diffusion" does get used in this way in English, but many native English speakers may be unfamiliar with it.
Thanks for the clarification, also on the use of the word diffusion. In social sciences it is common though, there is even a book titled “Diffusion of Innovations”.
That's 0,38 Euro/W of panel power, including inverter and cable. And there might be a solid price uptick on that because of the shop that's selling it. Wholesale from specialized shops is probably much cheaper...
The thing is: Prices are falling fast and that's great for everybody.
If your house is provisioned for 900W peak, you aren’t running a furnace, a/c, electric heat, or an EV. 4.8 kWh will go a long way in those circumstances. (It’d handle a fridge or two if you could time shift the power, or got one that’s designed to hold cold over night with no power)
I don’t think you strictly need utility approvals to install balcony solar. Usually, you can either not wire them into the house at all, or have a switch to switch the house between grid and solar. (It’s better to back feed into the grid, but that requires utility cooperation. If properly installed the switch I describe is safe but maybe illegal.)
Legality can be a funny thing. Governments can make anything they want illegal. Here in Argentina it's illegal to import used capital equipment that hasn't been refurbished by the original manufacturer or to import maps that say that the Malvinas Islands aren't part of Argentina. In Thailand it's illegal to step on paper currency because the king's face is on it.
Thinking about my home (in the UK) the "worst offenders" seem to be things that heat things, washing machine when it's heating water (~2.5kW), electric oven (~2-4kW), kettle (~1-2kW), electric heater (1-2kW).
Outside of those, we could have most other things on in the house and not be using much more than 1kW, though granted I've been very intentional with electrical efficiency with the electrical and electronic devices in our home (by UK standards).
But one thing to realize is that the industry was just lazy and none of this is actually "needs" a full electric line.
- You don't need actual heat for washing clothes if you using washing detergent. There are no real simple "machines" available as far as I know, except simple camping washing machines
- A rice cooker can work from as low as 250w. I have a "cooking" option in mine drawing 500w taking no longer than the usual 2000w plate (better isolation, optimized heat transfer, ...) to get water cooking.
- Heaters are difficult, I've tried a lot of electric options and they all draw a lot of power when you heat something like 20°C over the outside temperature. However ex. "Ecomat 2000" (small ceramic heater) can easily heat a average room at 450 watts.
One way to get warm and way lower wattage is heating blankets. From 50 - 100w usually on for 50% you get very far with little power.
Not sure if that helps anyone. But I spent a lot of time researching efficient caravan alternatives.
Ergo. 800 watts can be a lot.
2.) Russian politicians openly talk about such possibility.
3.) Russian interest in expansion is no secret.
War with Russia is a real possibility. Considering NATO is not reliable anymore (due USA being less then reliable partner) , considering China seem to low key support Russia, it is not even crazy from the Russian side.
Consider what Russia could possibly have to gain by randomly flying drones near civilian airports... nothing? Consider what NATO have to gain - stirring up anti-Russian sentiment, garnering consent for massive expenditure on an "EU drone wall" and continued money laundering in the Ukraine.
Please show me where Russian politicians openly talk about flying drones around European airports? I've seen Putin and others ridicule the very notion - and it really is ridiculous. Oh, I forgot about the supposed Russian drones in Poland too, drones which don't even have the range to get to Poland, and which had literally been duct-taped together from the remains of Russian drones and placed for a photoshoot!
Look at this map of NATO's expansion eastward toward Russia, and then please do tell about Russia's supposed expansion plans: https://commons.wikimedia.org/wiki/File:History_of_NATO_enla...
War with Russia is only a real possibility because the US and EU want it.
Senior population remembers soviet union with all its warts (rightfully so) but fail to account the structures that governed the union and whole topdown integration no longer exists there.
Meanwhile anyone born in the last 40 years was raised with inferiority complex due to being economically behind and treat every word from west as gospel.

NATO should do more to help Ukraine. They absolutely should.
>Look at this map of NATO's expansion eastward toward Russia,
That is countries deciding to join NATO in the hope it will protect them against Russia. No one forced them into NATO. Russia does not like it only because NATO prevents Russia from expanding. This is such a ridiculous talking point.
No it is not because of 3 reasons:
1. Russia has no resources to wage war on NATO 2. Russia has no resources to wage war on NATO 3. Russia has no resources to wage war on NATO
War with russia is mostly hawks' and chicken littles' of the media wet dreams.
Also: "if you want peace, prepare for war" has never been more true than now, as sad as that is.
Russia had previous success (with managable pushback) annexing Crimea (and the Chechen wars before).
Things just went south really hard this time and now they're kinda stuck, just like France/Germany in WW1 or the US in Vietnam and Afghanistan.
Writing off a lost war effort is also much harder for a totalitarian regime, because you are not gambling with your re-election: It's literally your life on the line, or your whole career at the very least (kleptocrat network & favors), so doubling down is kinda the most rational approach from the decision-makers PoV.
The entire war was planned as "It will be over in 3 days, we will accomplish all our objectives trivially, it will be a massive gain". There was never even an idea in the Kremlin that it would be anything other than a milk run, no contingency plan for if Ukraine fought back at all.
Russia did not even take control over hundreds of billions of dollars of cash reserves in foreign banks that they expected to be part of their war chest, and which were frozen early on.
Then they failed to take Hostomel airport, failed to be welcomed by the population, and their invasion column was an abysmal, laughable even, execution on whatever plan they had.
From that moment on, there was no "Success" option. It's geopolitical sunk cost fallacy.
Russia did not plan on losing over 4000 tanks! Russia did not plan on throwing away most of their Soviet inheritance and outright emptying all the storage yards for old tanks! They did not plan on causing the outright or near extinction of several entire types of Soviet military vehicle! They have lost 8000 IFVs! They definitely did not plan or want to lose several irreplaceable strategic aircraft, including multiple EWACS type aircraft that they didn't have a lot of in the first place, and again, irreplaceable.
Russia did not plan to have 30% of their fuel refining infrastructure damaged by a neighbor without a serious air force! Russia did not plan to have an attempted coup that was well on its way to Moscow. Russia did not plan on having most of its industry hampered by foreign export controls and limits.
Russia most certainly did not plan on having to beg and trade North Korea for a few million artillery shells, and they did not plan on having the Flagship of the Black Sea fleet sunk by a country who scuttled their navy months earlier!
If Ukraine rolled over and willingly submitted to total control today, including the actual populace (instead of resisting), Russia would still be utterly fucked for decades to come.
However I couldnt ignore this topic since im from Voronezh, Russia. Totally agree about government’s lies and impulsiveness, however:
- when they say “X is what totally not gonna happen” actually they introduce X event to the news so 99.99% it is gonna happen later
- impulsiveness huge, they got a lot of people in jail for labeling “svo” as “war” and in last months all the government refers to the conflict as to “the war”. However(!) they kinda translate will of the nation, some basic russians, trying to create narrative that will make average russian proud and happy and from the other side praying for any luck in war (actually they need not luck but supply chains, that ones are corrupted as hell, and that shit going for three centuries at least, nothing new)
So, about prep to a war I’m afraid you’re right, I don’t think it’s reasonable to stay at Russia at all for now at least for 6 years. Also it’s risky to stay in Poland and Finland. For Baltics not that risky but really depressing though. h o w e v e r
- russia had a deal for nato not to get close to its borders, that was violated in a really bad manner, the neighbor just stopped all communication from 2020 and at beginning 2022 declared cancellation of other deal of not to place any atom weapon nearby.
- USSR, and Russia asked to get in NATO a few times and got pretty rude responses “no way”. So there is nothing else this country can do if it doesn’t want to give up. The reasoning is pretty clear and emotional, stand for national security, do not became another India for UK. But the whole thing is messy, and smells like a slavs genocide. Russia became isolated, people are really angry and tolerable to constant violence threats, that is just insane turnaround since 2018 world cup that was hosted in Moscow.
This deal doesn't exist, at least anywhere on paper. There is an obligation related to the reunification of Germany that no NATO troops are stationed on the territory of former East Germany which has been honored by the reunited Germany.
Countries are also not forced into NATO, they ask to join.
> USSR, and Russia asked to get in NATO a few times and got pretty rude responses “no way”.
As far as I have read, Russia wanted to 'skip the queue' ahead of smaller countries. When this special treatment was denied, Russia suddenly didn't want to join anymore.
Just before Ukraine invasion Zelensky speak up about cancelling Budapest memorandum https://amp.rbc.ru/rbcnews/politics/19/02/2022/621108ac9a794... That’s not a first time Ukraine presidents discuss this, but that timing was tough.
About Russia - NATO membership: western media hold narrative “in 1990s Russia was close – in 2007 Putin declared independent way of using energy and army resources”, but I find this 2001 Bush reaction humiliating (reasons unknown, pure subjective observation) https://youtu.be/x7kkRkWbIzI?si=LBhci7V_qdWDBDT9
Putin says he saw some secret KGB documents about the whole east-west situation when he became a president, idk if that’s legit at all.
I can only add up to the topic that in 90s almost all oil/gas in Russia was exported by western companies, and only in 2002 all sources became formerly owned by russian companies and citizens. As for now 20% Rosneft still held by BP Russian Investments Limited.
Russia does have resources, it has the desire, and importantly the state it depends on (China) has a very strong motivation to have Nato distracted when it acts on its plans for Taiwan.
It's got to the point where the media/gov could claim Russians eat babies, and many would believe it.
