The first reference (for the definition) also links directly to a blog post created by OP.
Edit: Actually 4 of the references on that wiki page link to either OPs blog, YouTube, or projects. I can see why this article was declined, however broadly an article could exist for this concept if there were other sources to build on.
While this has clearly been written by / with help from an LLM, the general info is correct and matches what I have heard from those suppliers (although $0.21/W future pricing is far higher than the estimates I've seen)
The prices are still dropping per watt.
FYI if you look into what has happened in the wholesale solar market since the end of 2025, this is no longer true. Prices are now 20% higher than they were in Nov/Dec, and were even higher earlier this year. Hard to predict the future but we may have reached a price floor, as at 2025 prices the module suppliers were below cost and losing money. The market dynamics have changed significantly since then
No, I believe they were referring to this book: https://road.cc/content/review/192116-zinn-art-road-bike-mai...
You could try fermented drinks like Kefir or Kombucha? Otherwise I quite enjoy sparkling water with some enhancements like lime, or cucumber mint flavour drops
Yes, it's cheap
Thanks for the NZ link - just bought that bell as that's a pretty reasonable price & includes free shipping :)
This comment gives astroturfing vibes, like an LLM optimised version of masonhensley's comment: https://news.ycombinator.com/item?id=47587834
The entire country of New Zealand would disagree with you there - air heat pumps are our primary source of heating.
Reddit is not centered on user profiles and followers and yet
This is not entirely correct anymore, many of the new features added to Reddit over the last 5 years have focussed on expanding precisely this aspect of the site.
Not sure where that 150ml came from - our metric country (New Zealand) 1 cup is 250 ml.
That split can also be recognised by the change in naming- social networks vs social media.
I've been using Mylio on my laptop which might suit you? My main requirement was that I organise photos using my file structure for maximum portability, and this works well with that.
Another options (particularly if your org runs off MS outlook & Teams) - pencil in the review time as an appointment in your calendar, so your status shows as 'Busy' during that time. If that's not sufficient, you can even make it a Teams meeting with only yourself in it, so then your Teams status would show that you're in a call.
That's not the only version control through - if you use Excel connected to Onedrive or Sharepoint (like most major orgs in my country), then you have version history built-in tracking every edit going back months.
It be worth looking up the I-V curves of solar modules on a datasheet - a key factor is that the maximum power point of a solar module (for a given set of environmental conditions) is really dependent on the voltage that it is running at (whereas the current is more constant based on the light level, up to a certain voltage), so to get the maximum power out the resistance of the load needs to be matched to achieve that maximum power voltage (V_MP).
This is what MPPT controllers do, as this maximum power setpoint will change as environmental conditions change.
A solar panel's VoC should be its maximum possible output in ideal conditions (open circuit)
I think this is where the confusion arises - what do you mean by ideal conditions? Ideal conditions for solar generation are not necessarily at the same time as the highest voltage operating conditions. VoC tends to be specified at Standard Test Conditions which has light-levels representative of a sunny day (1000 W/m2) and a cell temperature (not ambient) of 25 degrees C, which is already a lot cooler than most panels would typically be at that level of irradiance. So really, the label is already specifying a voltage higher than what you would typically experience during times of max generation.
However, the max voltage could exceed this rating at times when there are cold ambient temperatures with enough light for the module to function, but not enough sun to meaningfully heat the cells. So in this scenario you may have maximum voltage, but you're far from maximum power nor at 'ideal conditions'.
This is information is generally stated on the module datasheets, which specify the Open Circuit Voltage (V_OC) at Standard Test Conditions (STC), and then provide a temperature coefficient for how that voltage changes with temperature. 'Maximum voltage' is very arbitrary as this is directly dependant on the lowest expected operating temperature, hence the industry has landed on stating these values at standardized conditions (STC and NOCT) allowing for direct comparison.
The label on the modules themselves tend to also provide these ratings at STC, e.g. this label from Jinko specifies the Open circuit voltage and also summarizes the conditions assumed for STC:
https://image.made-in-china.com/202f0j00LURcYuatWIqH/Jinko-M...
While I agree that the label could also add the temperature coefficient, I'm not sure if it's reasonable to expect that specialist electrical equipment details all of its operating parameters on an attached label without the expectation of consulting a datasheet or manual. For specific products that primarily target non-specialised consumers however, a different labelling approach may be warranted.
But that's not true - V_OC for PV modules is nearly always spec'd at STC or NOCT, which is clearly stated on module datasheets along with the temperature coefficient of that voltage.
E.g. choosing a random Jinko datasheet: https://jinkosolarcdn.shwebspace.com/uploads/JKM600-625N-66H...
V_OC is specified at both STC and NOTC, and the datasheet clearly states which environmental conditions accounted for in those test conditions.
As an outside observer of US culture I disagree, the normalisation and glorification of violence has always seemed to be a distinctly American value to me.
This really depends on the pricing mechanisms & contracts that large industrial users have with their energy provider. Many users may contract out of wholesale spot prices in favour for a more predictable contracted price - and demand response could form part of that contract. Depending on the market, financial hedges are also an option.
For instance, in New Zealand we have an aluminium smelter (Tiwai point) that constitutes about ~13% of national electricity demand. The smelter recently re-contracted its electricity supply with several of the major power companies (a 20-yr agreement) which includes a component for demand response when required. NZ has a ~80% renewable grid with hydro and wind as major variable sources, which creates both hourly and seasonal variation in the wholesale spot price (dependant on wind and rain resource). In the event of a major drought that pushes up prices due to a lack of hydro (this happened last year), the agreement with the smelter means it will shutdown some of its operating lines in exchange for demand response payments. This is exactly what occurred, whereas other industrial users that did not have such agreements in place or chose to take advantage of previously low spot prices without adequate hedging were then exposed and also shut down, without being paid to so.
if there is no accounting to prove it's green? It's almost as if this movement is a scam. No CO2 equivalent publications on solar, or on recycling
You state this as if that's a fact - just because you haven't looked for them doesn't mean they don't exist. Here's two examples showing that wind [1] and solar [2] have good environmental payback times in my home country due to avoided emissions, a country which already has an ~80% renewable grid. Additionally, [3] is a good resource that puts the potential waste from solar farms into context with other sources (such as coal ash) and shows this is an unfounded fear. Do some research and challenge your biases before you spread misinformation.

That sentence structure of the first example ('subject, long tangent, conclusion') is very common in the German language (and a major annoyance for me when reading German), so perhaps the author has that background?
Is Anna's Archive also blocked?
It's crazy to me how different it is across the Tasman - in NZ you can get 2 or 4 Gbps symmetrical for $150-180/m NZD in major cities.
especially popular among the German gay demographic.
Do you have a source for this? I highly doubt this
Vinfast? Not super well known though
I get where you're coming from, but let me correct some of your numbers for other readers:
you replace bricks every couple hundred years, but solar panels every 10–20, right?
Old panels perhaps, but modern solar panels come with performance warranties that guarantee they will be producing >85% of their initial output after 30 yrs.
2000W solar panel is like $300 or something and it's half the size of a door
2000W solar panels generally don't exist, so I assume that's a typo for 200W? Modern utility scale panels top out at ~700W with dimensions of 2.4 m x 1.3 m, however rooftop panels for commercial buildings are in the 500W range and ~ 2 x 1 m (so yeah about a door). International wholesale prices for these from Tier 1 manufacturers are now < $0.10 USD / W (although from what I understand more expensive in the USA).
Thanks for the work you've done with ShadeMap - I used this extensively when I we were looking for somewhere to rent, as living in hilly city some areas lose the sun quite quickly. Happy to say we are now living in a place that gets plenty of sun, and this summer has yielded a lot of tomatoes in a city where that can be difficult.
Yeah when it comes to these discussions, I think most people are unaware just how much the cost of solar & BESS (at the large scale) has fallen in the past couple years.
