PV Installation Hamburg Area

[mrloop]

We're looking at installing a solar power system on our Schuppen roof where there is enough space to go up to at most 10kWp installed. Looking at various sources e.g. Photovoltaik Forum, it seems that the cost should be around 1500 € per kWp all in. The offers we've had so far are substantially more than this - it may be a regional thing. So does anyone have any experience of an installation in the Hamburg area to share?

[Frantic]

How many offers you got ?
I am asking because when I did the same one year ago the offers were ranging from 14k to 27k euro , for the same kind of work
It was a Wild West, with some companies still frozen in (their) golden time where they could ask numbers to customer.

My suggestion is to keep gathering offers, dont stop to 2-3.

How many offers you got ?

For the PV? Can't remember but I could find it out. But knowing myself I probably got 3-4 and stopped when I noticed they were almost identical.
Fir the battery I got only one, was in line with what I was reading online, had a laugh and that was it.

BTW here my thread on my own PV

I already have 10 offers for installations sized from 5,34 to 10,32 kWp ranging from 16 to 25k and I waiting for at least another 3. It's a bit of a minefield,,,

@Alberto - it's been interesting to follow your thread about your PV I guess that you're not too far away (we're in NW Hamburg)

Pinneberg.
Installed ca 9kWp 13k€ (though I recovered the 19% MwSt, because Kleinunternehmer).

BTW why do you want PV?
For me it was a fun project.
Environmentally not sure it's a good thing. And I'm the hardest core environmentalist, mates call me green Taliban. The electricity is green, but is it really so good to offset PV production, transport usw? I don't know.
Financially, I definitely would NOT do it again. At least not this big. It will recover the cost during their 20yr life and Einspeisung, plus a win of ca 2% pa. But locking this capital away for 20yr, the stock market easily returns much better.

The most fun part is playing with the data. I am a data nerd physicist.
I save all our electricuty (production, use, bought, sold) at 5min interval.
A fun question I asked myself that I could answer with data, is the impact of a battery. We don't have a battery, I simulated it. Answer: battery cost several times what they would help save during their 20yr lifetime. Or worse if they break earlier, after all the warranty is 10yr.
I even got a battery quotation, was in line with the astronomical price you read in the media, had a laugh and that was that.
Another fun question answered with these data: how good is combining WP (Wärmepumpe) and PV?. Answer the WP gets almost zero if its electricity from the PV. After all when you need to heat the house (winter, night) solar radiation is generally very little at best, and viceversa.
Of course this is not what vendors say.

[..] but is it really so good to offset PV production, transport usw? [..]

I was recently reading a lot about this and I would say yes. Especially for those getting their power from coal.

"but is it really so good to offset PV production, transport usw?"

I was recently reading a lot about this and I would say yes. Especially for those getting their power from coal.

My PV will have produced 150MWh green before it stops
I measured its first 5yr, and I extrapolate during its expected 20yr lifetime. So I have some confidence on this quantity.
But how much harm to the environment did manufacturing my PV cause??????????? This I don't know, and I don't see how anyone could possibly quantify it.
I hope I'm wrong.

Not read much about this personally, but a friend of ours specially chose to use solar panels produced in Germany in order to reduce the transport costs, etc

[Fraufruit]

Most of the stuff we buy is transported long distances. Not just solar panels.

- and the point of my post was that it is possible to make more "mindful" purchases, and not have your shit transported half way around the world!!!

"most of the stuff we buy" is a huge generalization!!!

For those who are actually interested, there are very often alternatives that do not have to be transported very far, and they are of at least the same quality, if not better!!!

[Fraufruit]

I agree with you, Rob. Sourcing locally is great. There are some things like appliances, etc. that are mostly imported, though, and solar panels are one of those one-off purchases. All the better if they are made in Germany, of course.
