ᐅ Photovoltaic Systems for Self-Consumption

Hello everyone

I am currently considering installing a small solar system on the shed. The roof faces south with only a slight angle, about 95 degrees towards south.

I just want a small system to cover my electricity needs during the day. Unlike many others, we have a certain baseline load during the daytime. My partner works from home and always has two monitors and her computer running. In addition, of course, there are the usual electrical devices like lights, refrigerator, and so on.
Does it make sense to buy a 1000 watt-hour system in this situation? Or rather less? What do you think in general?

The saying "the devil is in the details" is definitely true – so what was the final result?

I don’t know. I haven’t made any progress so far.

But it wasn’t about net metering, but self-consumption, if I’m not mistaken. And that doesn’t work. If I feed into one phase, but the dryer is connected to another, I don’t have self-consumption, do I?

But, let’s say the dryer draws 2 kW on phase 2 and the photovoltaic system feeds 2 kW into phase 1, then the total at the meter is 0, just as if both were on the same phase.

True. Brain fog 😉

Ok, that already sounds reasonable and matches my suspicion. The meter needs to measure the total consumption in order to bill accordingly.
The question is whether the investment is worthwhile or not.
