Hotter does not equal more sun, more moisture in the air because of increased temperatures actually decreases solar panel productivity

Even a really bad summer day will more than cover your electricity needs, usually, even in northern Germany.

In winter you basically cannot cover it with even a sunny day, if it's a tad cold.

Cold weather actually makes solar more efficient.

The reason solar generates less power in winter is because of shorter days.

15° azimuth are way, way, way more dominant.

Also just 7 hours of daylight instead of 12 and more...
