ᐅ New single-family home with propane gas – is it possible without photovoltaic or solar panels?

Hello everyone,
for our building project, a 150 sqm (1,615 sq ft) single-family home for two people in Saxony, I am researching heating options in advance. Geothermal energy, heat pumps, and so on are somewhat familiar to me by now, but I am now wondering about heating with liquefied petroleum gas (LPG).
At the fully developed building plot, everything is connected except for a gas supply line. A few new buildings nearby have obviously chosen LPG, which is still relatively common in new construction here in the eastern part of our country (unlike in my former home region of Baden-Württemberg).
We will probably have lower heating demand since it will mostly be just the two of us at home; during the day, only one or sometimes nobody will be there.
From what I have read and hopefully understood correctly, photovoltaic systems alone usually make little sense; I had solar panels on my old house, which was nice, but whether it paid off over 10 years... I have no idea.
The general contractor will probably offer an air-to-water heat pump as standard, which I will definitely look into, as well as geothermal energy.
Still, I am also considering LPG because I have a large plot (to bury the tank) and the technology is reliable and well-proven.
With all the things like KfW funding, etc., I can’t seem to find any information about whether and what I must use in addition when choosing LPG.
So my question is:
Do I have to install an additional energy source if I use LPG?
Are there any sensible alternatives or ideas for using LPG?

That piqued my own interest, because I wanted to compare it with the specifications in the datasheet and see if the system settings are appropriate.
What bothers me is that a heating system doesn’t optimize itself, in the sense that I set my desired comfort temperature and the system manages it with minimal energy consumption.
Adjusting heating curves, schedules, and balancing the system only achieves about 80% of the potential for the specific house and its thermal retention capabilities.
Has there not been a doctoral thesis on this topic yet?
