#Renewables dominate 2025's newly installed generating capacity
2025’s power-generation numbers are not yet available, but data from 2024 shows #photovoltaics generating 7% of the world’s power, with wind at 8% and #nuclear at 9. That’s despite having 1.9 times as much #solar capacity as wind capacity. Solar is catching up fast with capacity up to 2.4 Terawatts, making it largest single source of renewable capacity by far, at more than Terawatt above either wind or hydro.

Researchers have developed the first universal model to accurately explain and predict energy level alignment at the interfaces between electrodes, hole-collecting monolayers (HCMs), and #perovskite layers in solar cells. This framework establishes physical guidelines for designing efficient, durable perovskite solar cells without relying heavily on trial and error.

Does someone here have opinions on salt based batteries? For home use with #photovoltaics on the roof.
I found https://www.salzstrom.com/category/all-products which seems to be as available as the lithium ones. Prices are also not that far off.
Much longer lifetime as well as not being lithium based seem to be a huge benefit.

Very nifty approach!
"Perovskite solar cells (PSCs) with power-conversion efficiencies comparable to established technologies hold huge promise for becoming the future photovoltaic technology, also given their versatility, low-cost and energy-efficient fabrication processes. However, PSCs are not stable under moderate reverse bias, an unavoidable situation under real-world operation, for instance, caused by partial shading of a module or installation with PSCs connected in series. Approaches to address this issue have focused on engineering the device architecture to enhance the breakdown voltage and mitigate the detrimental effects of reverse bias2,5,6. Here we present a completely different approach that fully solves the reverse-bias issue. With our Memsol, we developed a new concept of a solar cell with an integrated memristor, which protects the solar cell and simultaneously works as a bypass element. The memristor is realized by area-selective deposition of an additional metal–insulator stack and shares the perovskite and electrodes with the solar-cell part. Reverse-bias and shading tests show that the Memsol remains stable and automatically toggles between a low-resistance bypass state and full-efficiency solar-cell operation, dependent on the illumination and bias conditions."

☀️ Researchers from our university, together with colleagues from CSEM, have achieved a record 30% efficiency for triple-junction solar cells, which combine two thin-film perovskite cells and one silicon cell on a single device. The milestone could advance affordable next-generation solar technologies for space and terrestrial applications.

People fret about loss of spinning mass in generation systems, hence loss of automagical side-effect frequency control.
Here's some good news in that dept.
"This research investigates the economic viability of photovoltaic (PV) systems operating with an active power reserve to provide frequency containment reserve (FCR) services in the Netherlands. For that reason, the potential revenue of a PV system on the day-ahead (DA) market is compared to the FCR market using market price data from the period of January 1st to October 31st, 2024. Results show that there are 71 out of 304 days in which it is profitable for the considered 49.5 MWp PV system to provide FCR during the selected interval of 12:00–16:00 h. The PV system increased its revenue by €53 661 or 11.34% during these 71 days, which corresponds to a 2.87% increase compared to the total revenue earned on the DA market over the 10-month interval. Furthermore, aggregating the production of three PV plants reduces variability and increases minimum power output during the same 4-hour window. The minimum aggregated PV output power is higher than 10% of the nominal value for 85% of considered days, as opposed to 44%–53% for individual sites, while a delta power analysis shows a 22.9%–31.6% reduction in short-term variability through aggregation, demonstrating its potential to improve FCR provision viability."

RE: https://pkm.social/@ike/116213497374605036
The conversation with @ike led me to think about what #ClimateMitigation wedges @czds and I do:
1) #BESS a 15.4kWh battery energy storage system that allows us to time-shift our energy usage to less “dirty” grid sources and provides backup during outages
2) #photovoltaics and #windEnergy not enough to go off-grid but maybe enough to charge the BESS minimizing grid usage
3) Vegetarian for Clarise 100%, for me…I eat about 400-500g of meat/fish/poultry per month
4) Reduce travel… -
"... approximately 70% of PV modules are decommissioned before reaching the end of their design lifespan (around 25-30 years). A considerable share of these prematurely retired modules is refurbished, typically through basic cleaning and electrical testing, and reintroduced into secondary markets. Many of these refurbished units are subsequently exported, often exhibiting 10–20% power degradation and inconsistent quality."
There's a whole discussion to be had around this, especially in light of the declining rate of loss of capacity over the passing of years.
Refurbished units sold with a nominal rating being their remaining conversion capacity will be more durable generators than freshly built equipment. This ignores degradation of physical packaging but in terms of the fundamentals the PV cells themselves have essentially been stabilized by burn-in.
What's the net benefit of recycling working equipment and replacing it with freshly built? Does the input bridge the capacity loss of older cells, scrupulously accounted for?
More facetiously, many of us are only running at 80% or even less of original capacity. Are we a waste of space? 🙂

Not expected.
"Single-axis tracking solar PV power plants have an approximately 33% lower mean installed capacity density than fixed-tilt power plants, with estimates of 36 and 29 MW km−2 (without and with a 50 m buffer, respectively), compared to 54 and 43 MW km−2 for fixed-tilt systems."
Due to mutual shading it appears.
I'll guess that a _single_ tracking collector devoted to some highly local purpose will do better than a fixed-mount but apparently when deployed in groups, freedom of movement comes at a substantial density cost.

About me (for english readers):
I work as a pastor in the Protestant Church in Bavaria, have a trans* biography (came out in 2013) and am interested in scientific topics – especially with regard to the climate crisis, but also with regard to how we can motivate people in a democracy to adopt a different lifestyle (in order to achieve climate targets). I am also fascinated by biology, solar energy issues (photovoltaics, battery storage, etc.), e-mobility and, of course, human rights worldwide.

I remember many people (mostly white folks) telling me that I'm crazy & have no idea what I was talking about - when I told them that while Global North kept ignoring opportunities for shifting to more #SolarPower & more #WindEnergy to move away from #FossilFuels as part of longterm #EnergyProducing plans/infrastructure, China was going to kick global ass with their full investments on wind & solar #AlternativeEnergy. I said that in 1996.
China became the world's leading installer of #photovoltaics in 2013. China surpassed Germany as the world's largest producer of photovoltaic energy in 2015 & became the first country to have over 100 GW of total installed photovoltaic capacity in 2017. As of 2024, Chinese firms are the industry leaders in almost all of the key parts of the solar industry supply chain, including polysilicon, silicon wafers, batteries & photovoltaic modules.
#WindPower remained China's 3rd largest source of #electricity at the end of 2021, accounting for 7.5% of total power generation.
China is forecast to have 1200 GW of combined #wind & #solar capacity by 2030 as part of the government's pledge to increase the share of non-fossil fuels in primary #energy consumption to around 25% by that year.Both wind & solar energy industries in China have created thousands of sustainable jobs as well. They have boosted the Chinese economy from within.

On what has generally been a cloudy day, with occasional breaks allowing the sun to shine onto our driveway, and even though our F3800 battery energy storage systems #BESS have reached the 20% charge level to be kept in reserve for a sudden outage, the single 400W portable photovoltaic panel is keeping the BESS topped off to the point where we aren’t using any energy from the grid. This is amazing to @czds and me. 1/3

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.

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.

"We found American robin (Turdus migratorius), House finch (Haemorhous mexicanus), and House sparrow (Passer domesticus) nests across two sites: a tracking array and a fixed array. Results showed that robin nests in the tracking array exhibited significant architectural adaptations, including taller nests and greater variability in attachment angles, likely to enhance stability as panels moved throughout the day. Additionally, nests in tracking arrays experienced warmer thermal conditions than those in fixed arrays. These findings suggest that generalist bird species can adapt to nesting in dynamic, human-modified environments, modifying their nests to cope with structural movement and thermal changes."
