Accept offer for 16kwp photovoltaic at this time?

.. from May onwards, somehow the lines "Eigenverbrauch" and "Netzeinspeisung" no longer match the line "Erzeugung" .. or do I have a visual glitch? But overall, these are nice values :)

Hi, these are the values read directly from the RCT. What exactly do you mean doesn’t fit? (I have a small 4KWh battery, maybe the losses from it together with the inverter losses slightly distort the values, but roughly it fits for me?)

In the first 4 months, the values "Eigenverbrauch" and "Netzeinspeisung" always add up to the value "Erzeugung". After that, Erzeugung is always somewhat larger than the two individual values. About 10% .. I just happened to notice that.

So, here’s my two cents in Excel. When words just aren’t enough again.
23 kWp - December ’22 almost 2 weeks of snow on the roof - No BEV yet.
Heat pump consumption: 1960 kWh, including hot water.
So, I hope statements like "December + January yield = nothing" and "there’s no more than 5% self-sufficiency" can be put to rest as pub talk.
At least if the roof was meaningfully utilized.

Oh, and Happy New Year :)

So, here’s my input in Excel

Thanks everyone for the numbers and facts.
I took your numbers.
According to your numbers, calculated over 12 months, with estimated electricity costs of 40ct/kWh, you have an annual saving of 1266 euros. Additionally, with a feed-in tariff of 7.5ct, a yield of 1500 euros per year. That makes 2766 euros per year. Or am I calculating something wrong?! Also, have a good start to the new year.

I'm not going to double-check now, but it should be correct ;)
