Solar possible, how do I proceed? Help, tricks and tips

Hello, we have a 6-year-old house and an air heat pump as well as panels on the roof for water heating.

We are dealing with solar on the roof. Whether it is economically sensible, maintenance, self-use, feed-in, etc.

Are there funding programs or what would be the best point of contact for me?

Online?
On-site plumber or electrician?

We have 2 residential units, can the consumption be split?

... as well as for water heating panels on the roof.

Well, you already have solar... Or do you mean a photovoltaic system?

HelpHelp, are you bored?

You have been here so long that you should know that solar is only for meeting the energy saving ordinance in relation to gas.

Get a photovoltaic system installed and enjoy it, it can also supply you with electricity so that you can bathe hot cheaply/almost for free.
