Would be kinda interesting to see a histogram of the azimuths and/or tilt angles.

In my native Netherlands I'd guess to see that peaking at ~south at say 15-30 degrees, with some lower peaks at east/west combos.

Curious to see what it would be in this dataset.

I love that idea. I don't have time for anything elaborate today but I dropped two visualisations at the bottom of the post.

I love the radial one, which looks like it was laid out as a "mirror tower" installation and then maybe converted to PV?

Thanks, interesting to see!

Folks are doing some interesting exploration of the pros and cons of different alignments, e.g.:

> When roof area is limited, the question becomes: What layout lets you install the most space-efficient solar capacity within budget on the available area? In those scenarios, an east–west (E–W) layout can outperform a south-facing layout. The South layout may be “better positioned”, but the E-W allows the installation of more panels in the same area.

Basically examining 'quality versus quantity', depending on what your location and roof allows.

Yep, sounds all too familiar.

I installed a east/west facing set myself on our flat roof. Looking at dynamic power prices of the preceding year, multiplied by expected power output. Even wrote a simple space optimizer for this one time. But messed up some measurements so had to change on the fly anyways. The old adagium still holds: measure once and curse twice.

It should be roughly correlated with latitude (the exceptions being panels on sloped roofs which will match the roof slope).

Tilt should correlate to latitude for panels with an azimuth due South.

For panels with east/west azimuth, the tilt should correlate with where the sun is at 7-8AM and 17-18PM, at least in my area.

((I think you have your concept of azimuth and tilt mixed up; I know I have when I was originally typing a different parent comment)

I thought the thing to do these days is put them flat and as close together as practical. You lose a few points of efficiency but double the number of panels you can fit in a given area. And panels are so cheap that this trade-off makes perfect sense.

Can fit more if you tilt them a little bit. Also easier for maintenance/access, although they don't need much if at all beyond some cleaning.

There's a helpful chart here, which happens to match your approximate latitude:

Thnx!

Seems to match my experience as well, I got a set of 12 south facing panels and a set of 12 split over east and west on my flat roof. The E/W start and end a bit before/after the south facing set.

Does that warranty still apply if the battery is used for other applications besides it's core function of powering the car?

The car battery warranty is often for X years or Y cycles, whatever comes first.

Yeah, I guessed so. Using it as a home battery with incur a lot more cycles I suppose. Although if the battery is large enough so that a day of powering a home only drains the battery eg. 10%, how does that factor into the cycle count? Is that somewhere in the small print maybe?

I would look at your warranty, mine is 8 years or 100,000 miles. It doesn’t have a cycles stipulation.

That is an good next step, but also kind-of moving the goal posts.

Albania is fairly industrialized though I'd say: ~20% of GDP as per https://en.wikipedia.org/wiki/Albania?useskin=vector#Economy vs 15% of US economy as per https://en.wikipedia.org/wiki/Manufacturing_in_the_United_St...

> How is it decentralization Producers of electricity being everywhere is more distributed than relatively centralized power generation stations. Regardless of who paid (part of) it

Ha, very curious what the issue was and what textbook

Building a bouldering wall at home, for the kids.

A bunch of square panels with a grid pattern to mount hold on, with the panels hanging on french cleats (with a locking system, #TODO) so the panels are easily removable so I can hang something like planters on the wall as well with the same french cleats.

No AI, a bit of computers to draw things out in CAD, but otherwise just manual building stuff.

Pictures?

https://imgur.com/a/2TIye34 not much to see yet: square panels with a lot of M10 holes and edges (also the edges of the holes...) sealed. I just got the holds, bolts etc the other day. I sanded the panels & primed them for paint last night.

The larger panel is going to be a volume with a bit of a hang. Panels are all tough 18mm outdoor rated 'betonplex' with phenol? resin or the surfaces.

Cool, thanks for sharing! Don't forget maybe having some pads underneath for any falls :-)

Yeah, that table is going to be quite the natural selection filter I suppose. Crash pad is on the way.

My guess as a Dutch guy, not 100% familiar with our neighboring country's rules etc): Yes, exporting to the grids. If a house has an old Ferraris meter, it will rotate backwards or a new, smart(er) meter, that has a separate counter for delivery back to the grid.

Getting yourself installed as president while knowing you are incompetent (I mean, look at all those bankrupt businesses, he should know) is nefarious in itself. His entourage is nefarious for supporting the incompetency for their own gain.

If people are giving you money, are you truly incompetent?

I think we're using different scales to measure competency.

Competent enough to receive money, not competent enough to run a country well. But now we're getting into very subjective stuff, I'm sure his handlers are quite OK with what he's doing. It doesn't matter it all looks super suspicious, they are confident they won't face any consequences.

If you're incompetent maybe you don't know you're incompetent? I think probably a lot of people told him, but he's also very stubborn, so. He's been rocking that god fucking awful spray tan for decades now.

I mean, Christ, we have good spray tans, I know we do.

One of the few conspiracy theories I kinda believe is that Trump's 2016 presidential run was a grift and he expected to lose.

Everything since has just been an inability to admit he was in over his head, plus trying to get out of trouble for all the crimes he did. He (and Clinton) just underestimated how susceptible the US was to a demagogue. If you look at his face after the win was announced on election night, and after the first meeting with Obama for the transition, I think it shows plainly on his face.

Which is a shame in itself

Yep, sounds like "This was bound to happen at some point"

Which on some level is exactly "what the bosses and politicians want to hear"

When it's everybody's fault it's nobody's fault.

In some ways, yes, but yet it's what reality is. There was probably some last factor kicking in that triggered the cascade, but there were probably many non-happy-paths not properly covered by working backup/fallback strategies. So a report could totally still tell "it's X fault", pointing the finger there. Government would blame the owner of X, some public statement about fixing X would be made and then the ones working in the field should internally push toi improve/fix their own (reduced) scope.

I don't know what will come of this report in the next months/years, I will keep an eye on it though, since I live in Spain :)

Exactly.

But not across the Pyrenees :_)
