If you look at other countries, I wouldn’t assess personal (roof/balcony) solar on anything beyond own consumption savings. (Which with a local battery might work nicely, esp when charging cars at home)
Feeding back to the grid likely won’t be an ongoing thing at that scale.
(I think Australia is a pretty good example to look at, in practice people have personal solar+battery, and savings on your own consumption are much more valuable than the small feed in rate)
Ouch.
I thought for some reasons scaffolding means putting new bricks on your roof.
sorry for the missinderstanding. So if my post about this didnt make sense to you, you are absolutely right.
@nabalzbhf yes, own consumtion is interesting. Delivering it back to the grid not. From next year on thy can apply flexibel rates to pay you. So small money at peak production hours. Politics guarantees average of 6rp/kWh for installation singel home size.
The strategy should be to max out own use, I do it with vZEV which is a great tool. Afterwards a bigger battery which can ffed to the grid at night when tariffs are expected to be better. In AT they already have flexible tariffs for consumer. O think this will come also in CH. But first each EVU needs to provide the prices in a JSON file, so that electricity management system can be used to adapt your consumtion. I think there is a deadline end of the year for this
What would these certain shifts be? Got any predictions on energy prices and grid fees for the coming years?
The flexible rates are for feeding into the grid only, right? Not drawing from the grid.
For feed-in, as I understand the minimum fee applies only in comparison to a quarterly reference rate. If that is above 6rp, you’ll face the market prices, nevertheless. Meaning, you will face negative fees if you are feeding in at noon on a sunny summer day.
That aside, you’re absolutely right. If you have a combination of flexible consumption and battery storage, and even a zVEZ with more consumers than producers on top of it, you are well set.
That’s for the normal-size private PV. I think the plug-ins can still pay off after a few years, and the small production can be used easier. Even when a balcony or wall location might not get peak production, it should do well in winter months.
I assume that with the shift to the right within the EU, energz prices will fall - even if it means more gas/coal/muclear energy.
European industrial policy has been very naive. We spend all of our efforts with internal squabbles instead of solving problems.
We had energy dependence on Russian and the shock of the Ukraine war and are moving slowly on this. Iran happens and we still seem unprepared. We have now refined products shortages but still shutting down refineries which will increase vulnerability there too.
The one good shift is that nuclear is being considered again, but with long lead times, I will not hold my breath to see if this comes and even if it does, it will probably be massively expensive.
As for as electricity generation is concerned, renewable (incl battery storage) already won the cost race, and the prices still keep dropping (also you don’t have a permanent dependency on oil producing countries).
We got offers for around 6k CHF for 4 panels without battery or ~10k battery included. I realised quite a bit of those money would go to paying the seller who came in person to our house (and I was totally put off by the “only if you sign now” discount - wise gut).
I have a plug and play PV system with 2 panels, an inverter for max 600w.

Installed by a friend professional on my roof.
Total chf approx. 800.

Although this is a bit changing as I understand with the “free energy a few hours every day” plans that are now available there. It’s getting hard to justify installing solar when the majority their production is at a time where you can get electricity for 0 (network costs included).
Batteries are getting much more valuable though.
But this is an artefact of their pricing system. I agree with your point, self consumption is the way to go going forward. Not so much because rooftop solar is cheap, but because distribution costs are exploding and will keep on increasing in the future.
That results in an immediate “thank you for your time, we’re going with another offer”.
