Hello,
I wonder where you actually see the profitability, because with the above plan you will mostly produce electricity when you don’t need it; you will thus feed into the grid and buy expensive electricity when you need it.
Especially these days, photovoltaics are interesting if the appropriate storage medium is also purchased. However, economically only if you heat with an air-water heat pump; for pure household electricity I don’t really see the benefit in my opinion.
Curious question: why do you want to install a domestic hot water heat pump?

I am wondering how much potential there is compared to a sole gas condensing solution? The significantly higher costs would have to be saved again to achieve profitability...
