Reply to comment by michaelb1 in News Release: NREL Creates Highest Efficiency 1-Sun Solar Cell - 39.5% efficiency by TimeSpentWasting

My roof is maybe 40% covered, and it generates 106% of my electricity use. Are you super shaded? Or is your electricity use just insane?

My roof has a bunch of facets that makes it difficult to get a lot of panels up there. Not to mention the rules about panels have to be minimum distance from the edges.

Why not look into the solar panels that replace your shingles then?

Edit: Solar Panels not door Panel

are those a viable option? seems they'd be super expensive, limited availability (don't think i've ever seen one in real life, imagine only super wealthy people have them right now?), limited styles, etc.

they seem so neat tho. i just haven't tracked what's going on with that tech since before the pandemic 😅

Work in a sector that is one of the contractors involved in putting solar panels as car park roofs, yup they're very expensive due to how they need to have proper support, and water tighting it. Only places I've seeen these being installed in my country at least are universities and similar public institutions.

Yes they are crazy expensive, but as it turns out redoing the roof is also super expensive, so when you're doing it anyways, that's when it evens out.

They’re typically a lot less efficient than panels so it probably wouldn’t get them any more power

Some companies will move vents and stuff to fit more panels. A sunpower rep (I think it was them) mentioned that as an option instead of a tilt mount if necessary.

Usually thats just a sales tactic. Unless the company does in house roofing, they're likely pulling your leg

The Tesla solar roof is also a option but that means replacing your roof

It would have to actually exist in reality for it to be an option

There’s one a couple of blocks away from me. Looks pretty slick. That said, it’s the only one I’ve ever seen and they have 2 Teslas, if that tells you anything.

Location also matters, the further away from equator, the worse it gets.

Poor angles, shorter days, longer winters.

Not exactly true. Because in the summer our days are far far longer. In peak summer it's only is dark for about 5 hours here.

So you make up for it. As long as your allowed to supply back to the grid during that point it should balance out

If the grid has a buyer of last resort. This is where Bitcoin mining comes in handy, and is why it will help revolutionize modern grid economics.

There are tens of thousands, if not hundreds of thousands, of terawatt hours of energy, totally stranded. No way to monetize, thus never developed. The development of those assets will now have nigh-instant monetization. All you need is an internet connection.

This means sources of generation can be financed with a much shorter time horizon to cash-flow positive.

This means revolution.

I suggest, before you come at this take in a hostile fashion with pre-conceived notions, dig into Bitcoin a bit. Technically, it’s a marvel. The internet of money.

Tell me more about FTX then

callebbb t1_iy3hmi4 wrote

FTX is a perfect example of the folly of man. People took a decentralized money, where no trust in counter parties is necessary, and put it back in the centralized box.

FTX was a scam pretending to be an exchange. Ultimately, the users who withdrew their Bitcoin the moment it was purchased were unharmed.

A failure, no doubt, but not due to Bitcoin. It’s also not the first time this has happened. It will happen repeatedly, until people realize Bitcoin is a bearer asset, and they must take custody of their own money.

People want to believe there is something strikingly different about the Federal Reserve Bank (a private entity) and the Dollar. It really is just another shitcoin produced by insiders for nothing. Meanwhile, we have a sound money that is a technological innovation that won't be outdone for awhile, with no insiders, no permission required, no middlemen, no reliance on physical security or power projection, real scarcity, digitally native.

The cost to produce $1 is the same as producing $100 or $1 Billion or $6 Trillion.

Humans have trouble thinking in exponents... I use this example to show how large of a number $1 Trillion is compared to $1 Billion.

A million seconds is about 12 days.
A billion seconds is about 32 years.
A trillion seconds is 32,000 years...

The cost to produce example goes for every FIAT currency that exists globally. They are all digital ledger entries. And it is a permissioned landscape, wherein if you become an enemy of the state (easily these days), you are ostracized. Look at Kanye. Look at Venezuela. Look at Romania. Look at Turkey.

Billions of people NEED something like Bitcoin. The modern financial landscape excludes them, on purpose. For an in-group to exist, there must be an out-group.

I live veeeeery far away from the equator.

BookishByNaturee t1_iy2d0m1 wrote

I use about 1200 kWh a month. I live in a townhome so a very small roof compared to a house.

I had someone do a mock-up and it was 17 panels. Is it possible to get 15,000 kWh (or more, I’d like to go ev) out of 17 panels?

In Texas , south east facing roof (relatively flat)

JafaKiwi t1_iy2yfp1 wrote

There are many free online estimators where you can enter your exact location and the number of panels or peak power installed (17 panels x 400W = 6.8kW peak power) and it will calculate month by month generation. Some even take into account a typical weather patterns.

I don’t live alone either, and I don’t have an abnormal electricity use. Not sure what tech you’d have over me that would increase your consumption significantly.

Supercomputer and a time machine. Solar simply can't give me what I need yet.

I think you’re making that up. Why aren’t you using better panels from the future?

Future you doesn’t feel like bringing you back panels?

dropkickoz t1_iy189cs wrote

From what I understand, after 2028 the new panels/accumulators won't arouse unwanted interest from a local utility board. Have to wait until then.

There are actually so many factors you can't compare your solar panels and electricity consumption with random strangers on the internet.

  • he might live much further away from equator than you or just in an area with a lot of cloudy days

  • he might have electric heating so his consumption is much higher

  • his roof might be much smaller than yours

  • his modules might be older so producing not as much power per square foot/meter

  • might have larger family or simply different lifestyle with more cooking/ night activity

  • he might have an electric car
