Ah yes there ok, if we take the much shorter winter days and the days without sun, yes there you are certainly right.
But hey I understood the question as being an achievement mainly used in the summer.
Hello,
There is another parameter that we often forget in calculations of this type: it is the constitution of the panels.
The protective glass in addition to cutting certain wavelengths and attenuating the solar radiation has a restrictive effect on the duration of sunshine due to the jump in refractive index.
This gives a radiation penetration angle of + -40 to 45 ° relative to the perpendicular.
Apart from this "cone" only the diffused light will reach the cells and the output drops!
The exact equivalence measured is three times the peak power per day ......
