Construction costs are currently skyrocketing

I have a digital bidirectional meter. Approximately from 2.5 years ago.

The model is called SGM-DD-4A92T. If I read it correctly, it is a three-phase SmartMeter bidirectional meter. It was mentioned in another forum. So having that alone is enough to keep the 70%? That would be cool…

It is probably even the case (looked it up specifically today) that even existing systems for which the input tax has already been claimed and refunded can now be switched to "hobby" without consequences of partial repayment (however, this apparently only applies up to 30 kWp total of all systems owned by one owner)

The hobby classification refers to income tax and is already possible.


Your calculations are of course now rather pointless, since the whole continent wants to move away from gas. Heat pumps are accordingly poorly available and expensive. Now it is simply too late to think about it.
Gas will no longer require approval in new buildings starting next year. That chapter closes. Apart from that, I actually assume that electricity in particular (we _never_ had a power problem!) will become cheaper again next year, and gas as well. What we are experiencing right now is hysteria, as only Germans can spread it best. Whether gas, rapeseed oil (in a holiday in Turkey 5 liters for €2.50 on the shelf!), toilet paper or anything else – as soon as the Western world is threatened, everyone here goes crazy. Added to that is a certain type of person who fuels it.

I once read that by 2030 even 70 cents/kWh would be possible! But it could just as well swing the other way – though not as drastically.

New contracts are already at that level currently.

New contracts are already in place.

We will see these prices drop again...

But doesn’t it make more sense to put the 24 modules only on the south? Instead of splitting them up like that? In what numbers and which orientation?

I would rather have argued to get rid of the storage and instead fully allocate the money to east, south, and west. That way you still have quite a bit to manage in winter. But such nonsense with a few panels here and a few there......

I have 30 modules on a good south-facing gable roof.

Somehow your post confuses me a bit :-D
In the first paragraph, you question the constellation (east/south/west), and in the next you suggest exactly that. ;-)
Or did I misunderstand you?

If I had more south-facing area available on the hip roof, it would of course have been implemented in the plan long ago. But unfortunately I only have space for 6 modules on the south side. I also hadn’t planned any storage, and none was included in the offer for the 20k either.

But I finally have a second offer. Based on LG inverters and Cortex P3 solar modules. I haven’t dealt with the details yet. If I remove the storage, the mounting system, and the registration with the utility from the offer, I come to 16.3k, which I find "reasonable."
