Exploring financing options

The energy consultant is coming to us tomorrow and is supposed to plan the roof and its insulation, as well as check whether the windows in our offer fit the energy plan and are eligible for KfW funding.

Then with the roof plan, go to 3 roofing companies and have them create offers. That annoys me the most: for example, I have been chasing an electrical company for the 6th week now for a written cost estimate, which is really annoying...

Good thing we are only starting the renovation at the end of the year.

So we haven't made much progress yet. However, we are now tending towards a volume of 330,000-350,000 with a monthly burden of €1300. But that would also be plus energy with solar and storage

Do you mean a photovoltaic system by solar and an actual lithium-ion battery by storage?
