    This is ok.
    Peak is 10kWh+, for 6 hours of high production, 10 hours of some production.
    Avg use is about 600-800 W with 4-8 kWh when washing machines etc are in use.

    You state 11 MWh of production/yr.
    /360 = 0.03 = 30 kWh /day.
    = 3 kWh x 10 hours per day.
    This is incredible.

    What panels do You have and how many ?

    It is a Solar Edge system using 305W panels and I have 39 on my roof, facing south one side and west the other. Each panel has an optimizer and my inverter is a 10kW 3-phase inverter also from Solar Edge. The two trees cast a bit of shadow, and for maximum production, they should be cut down, but we decided to keep them for comfort, they reduce the heat inside the house during the summer.

    Incredible, but true and is normal here. My neighbours have about the same using different systems and slightly different installation. We have a yearly production of about 11 MWh as you can see. We have to heat during the winter (it's a bit colder here than in Barcelona), so half of our yearly consumption is for heating and hot water, and during that period we produce very little compared to the total need. A large portion of our consumption is pumped into our cars, we have an EV and a PHEV. The EV is used by my wife who needs it for quite a bit of driving and the car is always charged at home. My hybrid has enough battery to take me to and from work every day for the last three years and when I come home the battery is flat and needs to be charged. This will change soon since we are about to change cars, she will buy another EV with larger battery and I will also buy an EV with high capacity battery, but our total energy needs will not be much higher because our driving needs will be the same. Anyway, driving electric is still much cheaper than using petrol for the same trip.
