ᐅ Roof with photovoltaic system or alternative investments – experiences?

Hi,
I am currently planning to renovate our 29-year-old house. Apart from recurring maintenance work, no major modernization measures have been carried out so far. We have insulated the walls ourselves in the past, but nothing else.
This means the house:
- still has the original roof
- the original gas heating system
- the original windows on the ground floor
What is already decided and will be done in late summer/early autumn is a roof renovation according to KFW standards. The roof will be completely rebuilt and insulated.
Additionally, I have budgeted around 13,000 euros for a photovoltaic system. However, I am still unsure how practical installing a photovoltaic system really is. The company I am in contact with recommended using the electricity ourselves and feeding the surplus into the grid. My initial thought was to include a storage system to use electricity at night or during bad weather. The location would actually be ideal for a photovoltaic system, as our roof faces southeast.
That’s why I am now considering whether I should invest the money in a new heating system instead. Our heating has been in use since the house was built and has never caused any problems. However, I believe that new gas boilers operate more efficiently and should reduce gas consumption (hopefully). I would probably also have a bit of extra money left over to possibly replace some radiators, if that can contribute to better efficiency...
Maybe you have some advice or would like to share what you would do.
Regards

Heat pump and electric car go well together Misconception. The electricity for the heat pump is needed during the cold, dark months. The electric car is mostly not at home during the day, so it cannot be charged there.

Energy prices will continue to rise. That is not true; the electricity price remains largely stable, only the taxes on it are increasing.

Including or excluding taxes?@Bau-Schmidt How do I know that the electricity for the heat pump is mainly needed during the darker months? Well, when do people usually heat their homes?
And the fact that you use the car during the day should be the case when you actually need it. But if you’re at home all day, that’s a different situation. The question then is, why do you have a car at all?
But that’s okay, you have your opinion, and I have mine.
Honestly, I consider my time too valuable to continue this conversation with you.
