Roof covering and solar technician selection - Decision?

I now have 3 kWh per day after installing switchable power strips on all the mentioned devices.

Do you all always turn off your devices 100%? Do you press more than just the off button on the coffee machine, or do you all also have such power strips?

The warm water or circulation can't be the cause anyway since the air-water heat pump has a separate meter.

I don't know how else to explain it, sorry. I'll try again:

10 kWh before when we were away. Then the mentioned devices were unplugged, so the plugs were completely out, now it's 3 kWh per day when we are not at home. However, it's 11 kWh when we are there and, of course, have devices on. But I find that very high again because if I calculate it yearly, it comes to over 4000 kWh for 2 people.

Have you ever checked the manual to see how much your controlled residential ventilation system consumes? Depending on the setting, it's usually between 70 and 150 watts. So nearly 2 kWh per day is easily possible!

I don't feel like constantly turning off the TV in the living room at the socket directly and not just with the remote control. So unfortunately the 18W will continue to be used….

There are also clip-on adapters for the Schuko socket: you can control them via a smartphone app or set a timer program from there, they can also measure power consumption; they are available for around ten euros and up.

however, it is 11 kWh when we are there and of course have devices on. But I find that very much again because when I extrapolate that, I come back to over 4000 kWh per year for 2 people.

That is completely okay! You don't really think about it. Maybe more than the average, but also enough appliances standing around. In this respect, I rather see measurement problems in standby.

Dear all,

next week my photovoltaic system will finally be installed on my new building. At the time I signed for 49 x 410 watts (this is the maximum occupancy, half north/south). My installer now alternatively has 58 x 350 watts for me, because it would look nicer that way, since he wouldn’t have to install any modules crosswise (due to the slightly lower height). Attached you will find photos of both variants (on the north side I have two sanitary ventilators).

They are Q-cells G10 (410W) vs. G9 (350W).

He leaves it up to me to choose. Both are in stock and would cost me the same. The power would be almost identical: 58x350Wp=20.30kWp or 49x410=20.09kWp.
What is "better"? Do the 350W modules have any disadvantages? It would of course look nicer with the 350W modules.

Thanks in advance!

Sanitary fan!? You mean ventilation of the sanitary stacks? They can be built over, the brick manufacturer offers flat bricks.

how about 58 x 410 W modules ;)

That would of course be ideal, but unfortunately they don't fit...
