Hello,
we still have a question regarding our house construction: We want to install a photovoltaic system in the medium term, preferably combined with a battery storage. Since prices for batteries are expected to decrease in the coming years while quality improves, does it make sense to first install a photovoltaic system with partial self-consumption and feed the surplus into the grid, and then add the battery later to switch entirely to self-consumption? Or are there technical issues or other reasons why this might not be advisable?
Regardless of this, is it sufficient to only make preparations for a photovoltaic system, and what should the scope of these preparations be? For example, we have already planned an empty conduit from the roof to the basement for a future photovoltaic system.
Thank you for your opinions!

My electrician mentioned that he doesn’t offer Tesla battery storage systems to his customers because they are incredibly heavy and require a special forklift to lift them onto the wall. This generally makes installation difficult in many households.
Can anyone confirm this?Sebastian79 schrieb:
He should have breakfast more often – that unit weighs 100 kg (220 lbs). Forklift… *laughs*I haven’t looked into this point yet.
The plan was originally that if I ever do get a battery, I would place the storage unit below the inverter. So far, I assumed that the battery could also simply be placed underneath (possibly secured against tipping on the wall) and wouldn’t need to be mounted.
However, since I’m not planning to buy a battery anytime soon, I haven’t explored this in more detail yet.

Why?

Why? That’s how it sounded.
Have you already looked into it or do you have plans on how you want to proceed? First photovoltaic panels and storage later, or both at the same time?

I don’t yet consider storage technology to be mature or financially attractive.
