ᐅ Photovoltaic System: Costs and Savings Potential – Experiences?

But I’m happy to give you an answer anyway:

Call it naive idealism. Call it wanting something. Call it pointless nonsense if you like.
It’s just a buzz.
We would like to have one. You don’t.
So what?

I would like to have one, IF it were economically worthwhile. I just don’t see it that way. And your "argument" actually confirms that.

But I respect your attitude toward photovoltaics. I also have expensive hobbies that consume a lot of money and that not everyone can understand.

So, have fun and best regards

Yes, this was not meant as a provocation but simply a question about the source. So far, I haven’t found anything confirming that the nature conservation law will remove the cap.
There is a lot of information out there, but nothing definitive. In post 24, it just says “well, somehow it will be resolved.”

Post 24 contains an official transcript. The cap is mentioned there. Everything can be accessed on the German Bundestag’s website.

Furthermore, there is a results paper from the coalition parties’ negotiations on the climate package from September, which explicitly refers to the removal of the cap.

@Farilo
The reasons in favor of photovoltaic systems have been mentioned several times in this forum, including in this thread. Why are you asking questions that have already been answered? Should we now repeat the entire thread?

I’m not here to convince anyone, but your statements are just as generalizing as those from the photovoltaic lobby.

The photovoltaic system is the only part of a house that actually pays off over time, and when the second or third electricity bill comes, many start to consider whether photovoltaics make sense. My utility now charges 31 cents per kWh. With these prices, not only does switching providers make sense, but also installing a photovoltaic system, especially if you have an electric car.

But an increased fire risk combined with a much more complex and dangerous extinguishing process and the very likely lack of cost-effectiveness leaves no other conclusion at the moment.

You either didn’t read or didn’t understand the part about fire risk, so I’ll explain more clearly: With the Autarq solar tile system that I have on my roof, there is no fire hazard and no issues with extinguishing, since the voltage on the roof stays below 120 V (low voltage range). You don’t even need an electrician on the roof.

Everyone can calculate the payback period themselves. We chose an expensive system that only pays off after a longer time. The reason is simple: we just didn’t want what we see as ugly panels on the roof of our house. If you view photovoltaics purely as a financial product, you will always find alternatives and lament the days of high feed-in tariffs.

In the end, we simply wanted a beautiful house, built in an ecologically sensible way, with high lasting value, low ongoing operating costs, and a certain degree of energy self-sufficiency. This is where we live now. Goal achieved.

@Farilo no offense, but from your statements it’s clear that you have little understanding of photovoltaic systems and have never really looked into them in detail.

A photovoltaic system isn’t always the right choice. It depends on several factors. But on most standard roofs, it’s almost impossible not to make a profit with a photovoltaic installation.

I had one installed on my roof in December. And yes, what can I say. The projected profit is about 17,000 after 20 years, and that’s without me investing a single euro. So it’s fully financed.
Okay, not everyone can install such a good (and large) system on their roof, but it’s still very unlikely not to make a profit.

And no, this profit forecast did not come from the solar installers. Their estimates were much higher. I threw all of those away and did the calculations myself. Including all costs, expenses, taxes (VAT + income tax at my personal rate), interest, reserves, etc.

The fire risk from the system is no higher than from other electrical devices. And it is insured in case something really happens. Many systems require no maintenance (like mine, for example) and some require very little maintenance.

No one is forcing you to install a photovoltaic system on your roof, but please stop slowing down the energy transition by making such unfounded claims.
