100W 24x7? That's quite a lot, right?

This adds some color perhaps to the argument that this is for underserviced regions -- they don't mean third-world or impoverished even though it sounds like that, at least when I heard people defending Starlink.

Re:Starlink review, four months in by geerlingguy on Thursday July 22, 2021 @10:53AM (#27919605)
It's a little less than a modern efficient fridge (2-3 kWh/day). I used to have 100W light bulbs in the house, so it's not a crazy amount of power, but it's most significant to anyone planning on using Starlink 'off-grid', since it's a lot more than just a little 4G or 5G hotspot, or a standard DSL or Cable modem and router.
Re:Starlink review, four months in by morsch on Thursday July 22, 2021 @11:46AM (#27920218)
A modern efficient fridge uses way less than 1 kWh/day. The one I bought in 2018 uses 0.44 kWh/day. 2-3 kWh/day is awful.

Three random examples:

I should be more specific: an efficient 'USA-megahome-sized' fridge. Our typical fridge is often 25-35 cubic feet (850 litre)... that's about double the size of the small fridges used in many parts of the world.
Re:Starlink review, four months in by morsch on Friday July 23, 2021 @01:52AM (#27927647)
That's not an average size even in the USA and you could probably still do it on less than 1 kWh.

Of course, once you're doing the 'USA-megahome-sized' thing, it's pointless to bother with energy efficient fridges. And many people don't!

Re:Starlink review, four months in by SamBam on Thursday July 22, 2021 @11:08AM (#27919780)
Anyone know if Starlink is happy turning off and on again throughout the day?

I know we are all used to 24 hour internet, but if I were energy-conscious or off-grid, I might want to turn it on for 3-4 half-hour sessions during the day.

Re:Starlink review, four months in by geerlingguy on Thursday July 22, 2021 @11:14AM (#27919857)
I tested it a few times (putting in stow mode, turning off while I was rebuilding network rack, etc.), and it always picked back up within 2-4 minutes.

I know a few people who have Starlink on an outlet timer or WiFi switched outlet, and only have it run during the day. It seems to be okay with that.

Re:Starlink review, four months in by turtlebits on Thursday July 22, 2021 @11:58AM (#27920431)
Yes, 2.4kw in a day is a lot. I was hoping to switch to it from tethered cell service for my off-grid cabin. (I need 24/7 for security cameras), but it looks like I won't be able to without a substantial solar and battery addition.
Re:Starlink review, four months in by spookthesunset on Thursday July 22, 2021 @11:51AM (#27920308)
Is this power requirement just because the hardware hasn't had a chance for years of iteration or is it a "hard" requirement that no amount of product iteration can fix?

In other words is it 100W all the time because of physics or is it just "sub optimal" hardware that in theory can be mitigated through smarter protocols and fancier hardware?

Re:Starlink review, four months in by qayxc on Thursday July 22, 2021 @12:14PM (#27920697)
For the foreseeable future it's mostly physics.

The "all the time"-part is of course something that can be worked on even without changing the hardware. A simple switch on the outlet to turn it off during the night or if everybody is at work/school and thus doesn't need it would reduce power consumption a lot already.

"Fancier hardware" could also mean a timer for the outlet switch or a "smart home"-solution. This could mitigate connection time by turning the router back on before you arrive at home/wake-up.

There's a lot of potential for not having to use 100W all the time without hardware changes.

Re:Starlink review, four months in by aWidebrant on Thursday July 22, 2021 @12:56PM (#27921342)
Presuming that a large part of those 100 W go to the power amps for uplink transmissions, it seems that it should be possible to make at least that part scale with how much outgoing data the terminal is actually sending. But that may require new hardware, and it may conflict with the ambition of reducing cost per unit.
Re:Starlink review, four months in by user5994461 on Friday July 23, 2021 @08:16AM (#27929829)
I'd say 80% physics, 20% poor hardware/design.

Talking to a satellite in space through the atmosphere has a lot of attenuation. That's for the physics.

For comparison, wifi is 0.03W for 100 meters, mobile phones are 2W for 35km range. A satellite using 100W is not out of the ordinary.

There's a balance to decide on, power vs bandwidth, noting that doubling power has little effect on signal (log2). They could probably half the power for little difference in operation, but a notable difference on the bill.

It's exactly the sort of thing that should be adjustable, there could be a setting to adjust power/bandwidth/quality. Both for customers and for support.

edit: the video mentions up to 300 Mbps and up to 200W power consumption during snow (extra power to melt the snow). They have a lot of margin to reduce power while still being able to watch YouTube 4k.

Re:Starlink review, four months in by stordoff on Thursday July 22, 2021 @05:57PM (#27924869)
It would cost me about £11/month to run. For context, I currently pay ~£80/month for electricity (UK average is ~£60[1]). Not prohibitive, but it's a pretty sizeable increase. When you consider I can get 4G connectivity[2] for £22/month, with significantly less power consumption,, it doesn't seem that attractive unless you have no other options.

Re:Starlink review, four months in by flyingfences on Thursday July 22, 2021 @10:50AM (#27919568)
100W is a couple of light bulbs. It's not nothing, but it's not all that much. It'd be challenging off-grid, but not a concern anywhere with electrical infrastructure.
Re:Starlink review, four months in by humanistbot on Thursday July 22, 2021 @10:59AM (#27919674)
100W is a lot. It is a couple of very old incandescent bulbs or ten 60W equivalent LED bulbs.
Re:Starlink review, four months in by tigershark on Friday July 23, 2021 @01:01AM (#27927393)
No, it’s ONE incandescent bulb. And much less than the bulbs that were needed to light a fairly large room. We used to have a lot of 100W lights until not many years ago, honestly I don’t see the problem in spending that amount of energy if you have no other means to access a fast internet connection.
Re:Starlink review, four months in by katbyte on Thursday July 22, 2021 @05:27PM (#27924550)
perspective i guess - i used to use 2 100watt bulbs to light a single room.
Re:Starlink review, four months in by user5994461 on Friday July 23, 2021 @07:56AM (#27929694)
For perspective, these will cost around $0.3 a day in electricity, when in the room you spend most of your time in.

And yes, that's easily over a hundred dollar a year.

Re:Starlink review, four months in by ls612 on Thursday July 22, 2021 @11:57AM (#27920428)
It is a lot but it’s also outside so it won’t heat up your house and in most places it only adds up to about $10 a month or less on your power bill
Re:Starlink review, four months in by tialaramex on Thursday July 22, 2021 @12:08PM (#27920604)
A more durable reference comparison: 100W is similar to a human. An adult human, not exercising heavily, but not asleep, maybe reading a book, or talking to a friend, something in that ballpark.

Also, if you aren't off-grid, you're apparently not so far from civilisation that previous utility suppliers couldn't be bothered to provide service to you. Maybe if this generation's utility suppliers got their act together you wouldn't need Starlink anyway.

Re:Starlink review, four months in by martincmartin on Thursday July 22, 2021 @10:53AM (#27919598)
At 25c per kWhr, that's 60 cents a day, ~ $18/mo.
Re:Starlink review, four months in by geerlingguy on Thursday July 22, 2021 @11:15AM (#27919874)
To be clear, electrical rates are much different in different parts of the country. At my house in the suburbs outside St. Louis, MO, the cost is about $9/month. Not nothing, but not too significant compared to the total cost of the service.
Re:Starlink review, four months in by SamBam on Thursday July 22, 2021 @11:07AM (#27919763)
That's actually non-trivial. That makes the monthly cost nearly 20% higher.
Re:Starlink review, four months in by phire on Thursday July 22, 2021 @11:00AM (#27919692)
If it's your only (or best) option for decent internet, that cost probably won't consern you at all.

People who are off grid might grumble at having to provision more solar, battery and inverter capacity.

But for people who have other Internet options, $18/month might influence their decision.

Re:Starlink review, four months in by minhazm on Thursday July 22, 2021 @01:16PM (#27921610)
25c per kWh is pretty high, I think that's high even for CA. Most states are in the 12-13 cents per kWh range [1].

Re:Starlink review, four months in by skellington on Thursday July 22, 2021 @02:01PM (#27922194)
Electriciy in CA is ridiculously expensive. $0.27/kWh average rate is common in CA. Going up to $0.40+ if you get into the higher tiers.

But even with insane generation rates, most of the electric bill is the power company service fee, not the generation fee.

For example, out of a $200/mo bill, maybe $50 is electric generation, the rest is the service fee. PG&E is insanely badly run.

Re:Starlink review, four months in by SavantIdiot on Thursday July 22, 2021 @01:36PM (#27921846)
Many places are tiered, so if you go above a certain kW/h the rate doubles or triples. Cali and parts of NY state are like that (never lived anywhere else tho).

Re:Starlink review, four months in by oscardssmith on Thursday July 22, 2021 @10:58AM (#27919652)
It totally can make sense in third world improved regions, just not in homes (and/or possibly not on all the time). You could pretty easily run a small business off of 100 mb down, 50 up, and in that setting, you can probably power it with a small solar panel and just turn it off at night.
Re:Starlink review, four months in by humanistbot on Thursday July 22, 2021 @11:05AM (#27919736)
A "small" solar panel? A 100W solar panel is 2 x 3 ft (.60m x .90m). You'd need multiple panels even if you run it only during the day, because fixed solar doesn't just go from 0% to 100% once the sun rises.
Re:Starlink review, four months in by cyberge99 on Thursday July 22, 2021 @11:40AM (#27920147)
Solar technology, including the footprint is advancing rapidly. I believe there are panels that can do much higher wattage around that size. Your point stands though. “Small” is a relative term.
Re:Starlink review, four months in by qayxc on Thursday July 22, 2021 @12:20PM (#27920804)
> Solar technology, including the footprint is advancing rapidly.

Is it, though? The price drops have been significant, yes, but the efficiency of COTS panels hasn't seen any dramatic improvements in the past 20 years. Silicon panels have a theoretical limit of 29% efficiency and current models are close to 20%. There's not much room for improvement left there.

Re:Starlink review, four months in by skellington on Thursday July 22, 2021 @02:06PM (#27922251)
You would need 1 standard 400 watt solar panel ($250) plus batteries and inverter ($???) to power starlink 24 hours a day in this mythical zero power area that you all seem to be worried about.
Re:Starlink review, four months in by qayxc on Friday July 23, 2021 @05:14AM (#27928730)
In which fantasy land would that be the case?

A 400Wp panel won't be able to provide 400W most of the time to begin with. Unless you're in the middle of a desert near the equator and have a sun-tracking installation, weather and varying daylight hours are a thing.

Under realistic conditions, a single 400W panel gets you between half and two thirds of the required power (e.g. up to ~1.5kWh/day, depending on location).

Just a quick reminder: 400Wp means the panel produces 400W of electricity when brand new (it'll degrade over time), at 23°C ambient temperature and an incident angle of 0° (i.e. sun directly over it). None of that is generally the case 8h a day on average, which is why your estimation won't work.

Depending on where you live, optimal sun hours vary between 3.5h/day and 6.5/day (continental US) or 2.9/h/day to 5.9h/day (most of Europe) [0].

You'd also need to plan for big batteries, since seasonal differences may be huge depending on latitude.

Re:Starlink review, four months in by dboreham on Friday July 23, 2021 @12:57AM (#27927370)
A reliable 100W solar installation is indeed non-trivial especially at higher latitudes. Source: typing this on a packets routed via a solar powered relay site on a mountain. Our site only needs ~20W.
Re:Starlink review, four months in by ecpottinger on Thursday July 22, 2021 @11:24AM (#27919972)
A single 400 watt solar panel and batteries could power this 24/7, no problem.
Re:Starlink review, four months in by Syonyk on Thursday July 22, 2021 @01:51PM (#27922071)
No. It can't.

My office has 5kW of panel hung, 10kWh of battery, and my Starlink terminal is on the house system (grid tied) because an extra 2.4kWh/day isn't workable with my system in the winter, short of a LOT of generator time - I'm severely power limited during inversions, and the Starlink dish more than doubles my office's "idle power draw" (it's the property network hub, one of our internet connections, inverter idle, sleeping computers, etc).

Yesterday, the 15.9kWh system on the house produced 78kWh for a "sun factor" of about 4.9, so a 400W panel would produce about 2 kWh. Whoops. That's not 2.4.

In the dead of winter, the same system can produce 2.5 kWh - yes, 2.5 kWh on a 15.9kW nameplate system. A 400W panel won't even power on the charge controller in those conditions.

To reliably power a 100W load, 24/7, in most areas, requires probably 1500-2000W of panel and 20+kWh of battery - or someone willing to light a generator, which is the far cheaper option. But "a 400W panel and batteries" (implied as a trivial thing to set up) definitely won't. It won't even run it 24/7 in peak sun most of the year.

... and that's before it tries to melt the snow off. From the blog post:

> During the heavy snowfall, Dishy quickly spiked up to 125W, peaking at 175W towards the end of the snowstorm.

Solar panels don't produce much covered in snow, either.

Re:Starlink review, four months in by skellington on Thursday July 22, 2021 @02:11PM (#27922306)
You are probably technically correct, but most people don't need 24hr internet access, so that one 400 watt panel would provide high speed internet for let's say 12 hours a day and that's plenty for this odd scenario of living in a place with no power but still needing high speed internet.
Re:Starlink review, four months in by Syonyk on Thursday July 22, 2021 @05:34PM (#27924632)
The claim was 24/7 powering with "a 400W panel and some batteries" - which is simply false.

I deal with the realities of off-grid power in my office on a daily basis, and a vast majority of what's written about solar and batteries by people who don't have experience with them is simply wrong. I try to correct it where I can.

With a 400W panel and a few kWh of batteries, you could reasonably accomplish 14-16 hours of access during peak sun in the summer, 8-12 hours in spring and fall, and 0-3 hours in winter, except for 5-6 hours on sunny winter days.

Although I've heard that the newer Dishys use somewhat less power (50-70W), which does improve things.

Re:Starlink review, four months in by dboreham on Friday July 23, 2021 @01:03AM (#27927405)
Ah the joys of hiking 1000ft up a mountain in subzero temps through 4' drifts to clear ice off the panels. Although, for the most part I've found that provided you pitch the panels at 50 degrees or so, snow tends to slide off. The battery system has to be able to carry the load through 48h of zero panel output at least to let snow clear. In 20 years I've only had to physically clear ice off the panels three times.
Re:Starlink review, four months in by tigershark on Friday July 23, 2021 @01:12AM (#27927454)
48h is less than 5 kWh of batteries, one quarter of what the parent post proposed as the absolute minimum.
Re:Starlink review, four months in by Syonyk on Friday July 23, 2021 @05:18PM (#27935771)
It will depend somewhat on the area, and you can trade panel area for battery pack capacity to a reasonable extent - but you either need a lot of panel area to power you on dark days, or you need a lot of battery to ride through those periods. Out here, at least, we'll have a week where my 5kW of panel on my office produces less than 1kWh/day, often rather significantly less.

The problem is that after 48h, then... what do you have? You need to have either enough panel area to both run loads and charge the batteries, often in dim conditions, or you need a lot more battery.

Doing reliable off grid power takes a lot more than most people who haven't dealt with it assume, especially if you're dealing with serious winters and don't want to light a generator.

I'm basing my estimates off what it would require for me to run 2.4kWh/day, year round, without generator, on my office system - and it takes a LOT. I have 5kW of panel, 10kWh of battery, a typical winter day load of around 3kWh (base loads + minimal compute loads for a work day), and I still require a couple gallons a year of gas to run this reliably. Depending on the winter, I go through 3-5 gallons of propane for heat as well, though I've been trying to move to kerosene - more efficient, as I can run a lantern as a combined heat/light plant on my desk, and heat my hands, which are the only real constraint on cold temperature work in there.

I know those numbers sound somewhat nonsensical for a 100W load, but I literally make a living in an off-grid office...

Re:Starlink review, four months in by tigershark on Friday July 23, 2021 @01:11AM (#27927445)
How on Earth you would need 20+kWh of batteries for a system that even run 24/7 uses 2.4 kWh? And absolutely doesn’t make sense to run it 24/7, even when no one is using it, if you are running it off grid.
Re:Starlink review, four months in by turtlebits on Thursday July 22, 2021 @11:33AM (#27920072)
Doubtful. Most of the US does not get 6 hours of full/peak sun (2400w/6 = 400w)
Re:Starlink review, four months in by bick_nyers on Thursday July 22, 2021 @01:46PM (#27922000)
Gotta remember the double whammy here. Starlink is mostly rolled out at higher latitudes where solar power is less effective. Still, solar is cheaper than utility power most of the time. Might need 1.5 of those panels. Maybe I'm crazy, but I wouldn't consider off-grid unless I had like a 5KWh array at a minimum. Probably with wood burning stove as primary heating source if I really couldn't expand that solar for electric heating due to cost.

With heat inverter pump tech. taking over fridges, water heaters, AC, etc. and making them so much more efficient, it can give a lot of headroom on energy requirements.

Re:Starlink review, four months in by ClumsyPilot on Thursday July 22, 2021 @11:43AM (#27920178)
Only if you live in the Sahara. Panels are rated for power they produce at 1,000W/m2 irradiance, in UK average is 100W, that panel will produce 40W on average.
Re:Starlink review, four months in by turtlebits on Thursday July 22, 2021 @12:04PM (#27920536)
That seems absurdly low. My 250w panels get within 90% of rated output and I'm in Seattle.
Re:Starlink review, four months in by coder543 on Thursday July 22, 2021 @12:27PM (#27920927)
I think they're averaging throughout the year, using the number of "Mean Annual Sunshine Hours" * "Percent Possible Sunshine", which would account for average cloud cover and such.

I'm sure that for a few hours during the summer, the solar irradiance in London is probably 90% of what it is at the equator. That doesn't help most of the year.
