The last two days we have had solid rain.
Minimal solar production.., at the same time I can not complain too much we did get an average of 5 kWh of production. That is more then 20% of our power even though it was a steady rain from solar.
The sun has been hiding out a bit today but we will get something between 15 and 20 kWh today.
So, if it is raining you seem to get 15% to 25% of your normal production and if it is overcast but not raining we seem to get between 25%-50% of the normal production.
Luckly it does not rain much here and I hope when it does it is in the middle of the night.
