The standard 2x1 #solar modules are the new tatami mats. Cheap, ubiquitous commodity.

How Pakistan pulled off one of the fastest solar revolutions in the world

Pakistan has become one of the biggest new solar markets. It’s bringing cheap, clean power but analysts warn of potential trouble ahead.

6/n The Anker Solix app does show some data, such as the amount of solar power being generated during the day. It’s easy to see where we adjusted the PV panels throughout the day. The peaks, at 250-270W, are where the panels are nicely lined up with the sun, shadow sharply straight behind the panels.

5/n Screen capture of the Anker Solix app showing power going from the PV panels to the battery systems to the Home Power Panel to the house, with nothing coming from the grid. The app is a rudimentary #DigitalTwin the animation is somewhat informative. It can be disconcerting when the PV panel on the ground disappears when it’s too dark for it to generate any electricity

4/n The photovoltaic panel is more of a test. Is it really worth it where we live? The day it was delivered was cloudy and misting; we still got 100-200W from it. Today was bright and sunny, and we got 250-300W. Not bad from a panel rated at 400W.

Ist schon echt spannend, wenn man seine PV-Daten einfach mal in PowerBI auswertet und diese dann anfangen, Geschichten zu erzählen (wann lag Schnee, wann waren wir unterwegs, ...).

In dem Fall auch top, dass mein Anbieter mir Jahresreports als csv ausgibt für solche Spielereien) #data #powerbi #photovoltaics #photovoltaik

"Total weighted average efficiency of crystalline Silicon wafer-based [PV] modules is 22% in Q4-2024."

If we consider degradation to 90% functionality as EOL, many of us should have been removed and replaced long ago. Me, for instance.

Anyway, here's a very nice explanation of how PV panels decline over time.

For my part I think that producing 9kW instead of 10kW is a feeble argument for the expense, hassle and especially footprint of replacement. Can"t squeeze 10% consumption reduction over the span of 20 years? What's the empirical record, outside of the AI Tulip Mania or other aberrations?

How long do residential solar panels last?

Several factors affect the productive lifespan of a residential solar panel. In the first part of a series, we look at the solar panels themselves.

Oder anders dargestellt: 32% der erzeugten Leistung belasten das Netz gar nicht oder zu Zeiten in denen Peaks nicht so häufig auftreten und #erneuerbarenergien lt. @peakpick_de eher mäßig vertreten sind.

Um es mit Tim Meyer zu sagen: Es ist einfach cool sich damit auseinanderzusetzen und seinen Beitrag zu leisten 😄
