Okay! The battery is mostly charged and it’s not even 2PM, that means a vacuuming session right now!
… half an hour later, I drained a third of the charge (appliance draws 1.3kW) and it looks like the battery is going to be full again by 5PM
I was right to move the panels though, being side by side didn’t allow for much time without shadows on either. But now they are both fully lit for several hours.
The IEA just updated its PV life cycle assessment data with a comprehensive look at current cell tech and installation systems. #photovoltaics
Fall update on my urban plug-in solar panels
I’m seeing how the lower sun in this season affects energy production and how that relates to positioning the panels in my garden for best yield
Looks like the best I can hope for is 560W, while the panels’ rated output is 400W each; I can’t reposition my panels like I used to, there are shadows everywhere else
These days I’m still powering the laundry machine from the battery in addition to feeding those 190W to the grid, but soon I will have to choose
Some of the shadows I could deal with; there’s a fig tree that I really don’t need here and the other tiny bush is also not in the best location; but other shadows come from the neighboring garden and I’ll have to wait for the seasonal trim, probably next month
I guess that against the wall on the right would be best for this season; that wall faces straight south and isn’t shadowed, but it also has a shorter range in the day
(Reminder that this isn’t about saving money, but to see what I can do to lighten the load from the grid)

Agrivoltaics are getting more common in the south of France, but it looks like things in the US might be a bit behind. This is a good article about the situation in the States, with pros and cons...
Overall, it can be a boon in the right situation, so it's worth looking into..

#Photovoltaics are still running after a year under Swiss #trains
100m #photovoltaic installation on a #railway line open to traffic, inaugurated April 24, 2025 in #Switzerland. It's fair to say it went well; 48 #solapanels wedged between tracks have generated more than 19MWh
According to the company's CEO, Joseph Scuderi, more than 11,000 trains have passed over the #solar power plant without incident. There has been no impact on railway operations or solar generation.

I discovered #Africa #photovoltaics #youtube today.
If you need competent info on how to wire an inverter in an arrangement that isn't covered by the manual - find a black dude with poor English. It will be flawless.
I wonder if the #africanMastodon could tell me: is English the main language used internationally on the continent? Or it depends? What's the #linguafranca there
Kind of a naive question about residential photovoltaics
How feasible is it to install a big battery at home to become self sufficient?
I was thinking 150 or 200 kWh? Do these systems exist, is sodium there yet, etc
There is space here for about a dozen 500 W or so panels, that’s just above 7 kWc as I was told (I don’t understand their math). Daily electricity usage is certainly less than 10 kWh all year, often closer to 6. Everything is electric, big spikes while cooking.
I know the summer would have a lot of over production that wouldn’t sell well, and spring/fall would probably be just about even; winter would likely need to charge at night (in the Paris area, France).
(I know how much the air/water heat pump makes this a crazy idea that requires cross seasonal storage that doesn’t exist yet, residentially, so let’s leave it out)
I just finished the first version of a small software for managing the balcony solar plant of some family members. It works completely without any cloud or any other people's computers or even an internet connection.
There's three panels and an inverter with a battery. Any power initially is used in the household, then if anything is left it's put into the battery for later use, or if the battery is full, fed it into the public grid (to get a small financial compensation). Or if you want to, you can override that and just charge the battery, or even charge it from the grid.
Of course the inverter originally needs a cloud connection and comes with an app that needs a cloud connection and obviously is described as AI-powered very smart whatever. But there is a documented API for getting and setting some values! Interoperability! Without the cloud, there's hardly any logic built in. So I had to create it myself.
It's just a few HTTP requests, json, a SQLite database, and some very basic HTML.

I like this idea very much. The more solar the better. Now, I would like to see more utilities provide home battery systems for resiliency across their service area

#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.

#Perovskite solar cells are an emerging, highly efficient technology for converting solar light into electricity that have recently been engineered with molecular anchors to withstand the structural deterioration caused by extreme environmental temperature swings.

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.
