ᐅ Natural Gas + Photovoltaics – Experiences with the Energy Saving Regulation (EnEV) from 2016

Hello everyone,
A quick note upfront: we are not required to meet KfW 70 or KfW 55 standards, but of course we must comply with the 2016 energy saving regulation.
We plan to use natural gas heating combined with a photovoltaic system on the roof. We will probably use a 36.5 cm (14 inches) BIMS thermal brick.
Does anyone have experience with combining photovoltaics and natural gas? Can this setup achieve the necessary energy values without relying on very high insulation levels?
There is a lot of information online about solar thermal (for hot water) and gas, but not much about photovoltaics and gas. From my perspective, we gain more energy from the sun with photovoltaics than with two solar panels extracting heat energy.
Thank you very much for your answers.

And why not just go for a heat pump? That way, you can save on solar thermal and photovoltaic systems (and the gas connection) for now. There are plenty of threads here about batteries, photovoltaics, and heat pumps showing it can be done, but it doesn’t really offer a financial advantage.The quotes from the general contractors with heat pumps didn’t fit the budget, or they only offered combined units (controlled mechanical ventilation and heat pump).
I understand there’s no financial benefit. I’m just looking for a way to get the solar thermal panels off the roof, because I prefer photovoltaic better. Battery and heat pumps are a consideration for the future—I don’t know what will come of it.

Much higher initial costs, distance issues with the neighbor, the entire heat pump has to be replaced after 15–20 years, dependence on electricity, especially at very low temperatures, when the hot water tank is empty, heating takes several hours, etc.
Wherever possible, I prefer a gas heating system.
