How much does it cost for a reasonable 10 kWp rooftop photovoltaic system?
I've already found modules online for €2,000. However, I read elsewhere that you'd have to pay at least €10,000, which is too much for me. I'd install the whole thing myself, and an electrician would do the wiring, of course.
However, the modules do not get on the roof by themselves and without installation material.
Cables, inverters, HAK and bureaucracy, planning, plant removal and there are also not free of charge.
In addition, it seems to increasingly crystallize out from experienced insider circles that the cheapest mass goods on PV modules seem to suffer more and more frequently from quality / and long-term functional problems.

There it is also not surprising, which is why solateures that offer particularly favorable conditions are also waiting to register insolvency at an early stage.
Yes, with these “complete offers” it really sucks in the fingers.
However, the roof hook fastenings, the screws, the substructure and sometimes also the suitable inverter incl. I don’t know. That would be all on top.
In addition, as you write, you have to put all the crest on your own Roof hieven, build everything professionally, drill through the roof and trallalala.
If you trust this and you are sure that everything is really necessary in that “complete package”, then I will only wish you a lot of success!
If it works then I don’t care about it.
You can’t start with the modules alone.
You need an inverter and a memory. And then of course all the parts for assembly. The modules are often not the most expensive part of a proper PV system.
And then you need to consider whether you want to use your PV even in case of power failure. The normal systems only run when the “network clock” gets from outside.
For island location or Blackfall requires extensive wiring. The house must separate from the network and excess consumers so that the inverter can supply the necessary equipment further. That makes everything much more expensive.
Well, there are complete sets with inverters for 2000 Euro
If you think you’re happy, why don’t you just get that thing?
Let’s get out…You need…
Then you can also leave the modules away
You can’t feed that much without a special contract and then you get at most half of the electricity price remunerated and then you have to buy the electricity back expensive. The full performance brings things only in the middle of summer, at noon in the best weather. So always if you don’t really need the power yourself. In the morning, in the evening and especially at night, you buy more expensive electricity. And in winter anyway!
Only if you use the electricity yourself completely you save money.
And there’s nothing wrong with power failure without memory anyway.
On what basis are the calculations?
You get the 10kW only in the middle of summer, 1200 at noon with cloudless sky. Now in winter, you’ll be happy if you reach only 1% of it.
And you can only feed in more than 800W if you have a corresponding contract with the power provider. And he introduces you how the system must be connected and puts conditions to the hardware.
And even if you save 800 a year, the thing has to run for more than 3 years so that the effort has been rewarded when the kit costs €2000.
I’m out of there, because your tried doctoral thesis as a salesman for every will does not take my week.
My calculations have shown that I could save about 800 euros per year. I am also concerned with the environment. It is easy to eat, a farmer feeds 60kw as far as I know
I see other reasons why this thing doesn’t work.
For the €2000 you can buy a whole amount of electricity, so much the thing will hardly “saving” in a few years.
I’m referring to the questioner’s question in my answers and you’re writing novels that’s all different.
This is about the question of what to spend on a reasonable investment, not your personal preferences.
For fear that the part will endure after 2 years.
You start to lament without specific nominal performances and uses. That’s why I’m going out.
So you think a €2000 complete set, probably “without everything” is reasonable and a €10,000 system is unreasonable?
Then, as I do DiY in all preparation also make it for cabling SO, that the decreasing Eli only has to measure and look over it for the final acceptance of such a sized net feeder thing.
And now don’t ask for any further embrittlement between full island and potentially net-feeding facilities with hybrid-WR.
With a 10 KWP feeder, however, I would also have a plan for what exactly at the psing time should be about 230V lüppen without memory.
And 10 KWP generator area under STC hasn’t said anything yet about what the system really did when on average and how to grow into the 230V grid depending on the generator orientation and weather.
Constantly monitored memory now eats energy in readiness during a healthy calculation. And in winter as well as in schetweetters it is usually hardly above basic requirements depending on the household.
Therefore borrowed separate emergency needs island vs. Network feeders next to each other.
I also have a 12V system for emergency power. I have a sleep apnea device and I would like to continue using it during a nightly power failure.
At the facility I can also refuel my power station and use 230V devices.
Actually, this is only about 1kWh of battery storage. However, I find the missed yield a pity and therefore have 12V lighting (bedroom, veranda), all USB devices for charging and still various other things that can run more or less directly with 12V.
I’m not trying to feed in, because the 260W peak almost doesn’t bring any money.
But the question was: “How much do you pay for one reasonable 10 kwp. And it’s too sensible to save money. And this is not possible with the €2000 Wunderdingens that the questioner has found there. In any case, even if I didn’t see it, I wouldn’t classify it as “reasonable”.
Memory is and remains a question of profitability for amortization. In any case, without memory, I lock and use my on-grid subsystem in a targeted manner when it also throws its peaks.
The small island licks only next to 12V for cases of a real BA long ago with compatible basic devices for pure emergency.
And no, I’m not a prepper.
A module (450) watt is available for around 100 euros. For ten KW you need about 20 modules, i.e. 2000 euros. Just as much you have to spend on the inverter. Then make about 5,000 euros for the technology with cable plugs and so on.
But come on! You must not forget the rooftop services. And the electricity costs. This is a multiple of the technical price. I paid about 20,000 euros of rooftop services back then. Well, it was a tile roof with bricks, where they had to clink all bricks to fasten the brackets.
