Auch kleinstes Glück soĺl man wertschätzen. 
Heute war die PV-Anlage mit ~ 10 kWh nicht sehr ergiebig. Das Wetter war insgesamt nicht PV-freundlich, aber es reichte für 100 % Autarkie und etwas Einspeisung.
Während die Pizza im Backofen war, tat sich eine Lücke in der Wolkendecke auf und der Strombedarf konnte ohne Rückgriff auf die Batterie gedeckt werden.
So schön ist #Bayern!

Solar is winning the energy race and China is leading
The world’s cheapest power source is scaling at warp speed, pushing coal, gas and nuclear aside.
- 228 gigawatts in 2015, providing 1% of the world's electricity
- 759 GW in 2020, or roughly 3% of global energy demand
- 2,919 GW in 2025, according to estimates — solar now supplies about 10% of the world's energy, more than nuclear at 9%
Solar cells just passed the Shockley-Queisser limit (solar cells can only utilize about 1/3 of incoming sunlight)
Under normal conditions, each photon produces only one spin-singlet exciton after excitation. With SF (singlet fission), this single exciton can split into two lower-energy spin-triplet excitons, which could effectively double the available energy.

A new solar breakthrough may overcome a long-standing efficiency barrier. Researchers used a “spin-flip” metal complex to capture and multiply energy from sunlight through singlet fission. The result reached about 130% efficiency, meaning more energy carriers were produced than photons absorbed. This could lead to much more powerful solar panels in the future.
