    Some people are happy living in the dark ages, Some people smoke too , same way of thinking to me.
    No point arguing if thats the way they choose to live their lives.

    Solar still works on overcast days. Just check the UV index on a rainy day, it can still be high. I have monitored our solar on overcast days and it's still working. So is the solar hot water. Don't forget the ideal temperature for solar is in the 20-25 degree range.

    A little north of Wagga NSW.

    Our 8kW PV system produces very little on cloudy days.

    8kW so that it generates enough power to run the HWS long enough in winter if the sun is shining - can't do anything about overcast days. Unfortunately export is limited to 5kW in NSW for single phase installations.

    Regarding rooftop solar panels in the USA.
    Attachment 150068

    This is snow coverage in the USA and Canada as at YESTERDAY.

    Imagine the snow cover during January, February and March. So it is reasonable to assume that the area was much greater over the last 3 Months. That would really require some big batteries.

    I understand that the USA is facing a "French Fry" shortage as the farmers have been unable to plant in Washington and Idaho.
    Regards Philip A

    What's the UV rating in the areas with snow?
    Plenty of solar panels in Germany, where it also snows.
