ᐅ A photovoltaic system that pays for itself and breaks even on a monthly basis

Hello everyone…
Is it possible, in general terms, to install a photovoltaic system on a roof that pays for itself every month?
In other words, does it generate enough electricity so that a loan taken out for the system is covered by the savings on our electricity bills?
What is the current cost per square meter for a photovoltaic system, including installation and everything else? And how much electricity can it produce if installed on a south-east hip roof with a 28° pitch?
I have absolutely no idea about the amounts involved—both the cost of such a system and the electricity it generates.
We would probably need to install a battery as well… I also don’t know what that would cost.
A few experiences would be great, possibly even with concrete financing tips or personal stories.

And with that, a stationary battery storage would be even less worthwhile for you. Yes, if the car were plugged in during the day. But I only get home at 5 p.m. Then in summer, there are at most 3 kWh (3.3 kWh) available for a maximum of 2 hours, so I have to draw from the grid without storage. In spring and autumn, it’s even worse.
But it doesn’t really matter. I’m not an advocate of storage solutions anyway; I just want to get rid of the money that’s still available.
Of course, that’s possible!
Attached is my calculation for the photovoltaic system. The scaffolding will be installed tomorrow. In 3 weeks, it will be on the roof, and it will officially start operating in January.
I would not recommend a battery storage system!
My system is calculated with a relatively high self-sufficiency rate of 50%. This applies to our situation; others might only achieve 30 to 35%. Nevertheless, the system would still generate a positive cash flow after taxes from the first year.

Best regards,
Specki Why? What appliances do you have that consume so much around midday that you want to achieve 50% self-sufficiency? There are also people who don’t manage that even with battery storage!
