Most of them are overpriced, but they do work provided you can keep the panels in full sun for the day.

>>2840559
They are very much a scam. The only reason they are as cheap and as ubiquitous as they are is because of government interference in the free market. Solar panels are good for calculators, highly mobile off-grid, and very off-grid permanent living. Everything else has been a misallocation of capital and a disaster for the human race.

>>2840559
>SCAM
At the level in op pic, no. Not a scam. You can recharge your devices, power a radio or satellite up/down link, pc/laptop, TV. If those things are important to you, yes not a scam. Powering your fridge/deep freezer for a couple of days is just a matter of scale. This could save lives by refrigerating medications or $100s even $1000s in food preservation. As I said, scaling to your requirements (or desire) is the key to functionality. Over do your system and you have a surplus. Under scale, and your fridge goes hot in a day or less. Think of it as an intermediate step to full off-the-grid.
>>2840571
>a disaster for the human race.
Drama queen much? Whew.

Only inasmuch as that size panel charging that size battery would take many hours of direct sunlight. When I've been car camping I rarely stay in one place for enough hours to be worth setting up the solar panel.
The battery is ace though for keeping the fridge running since I don't have dual battery system in the car.

Performance is whatever you make of it. If you want to charge faster you can get more panels. It's up to you to do math and figure out how long you can keep them in the sun and how many watts you need for your devices. A 100 watt panel in full sun for 6-8 hrs should be able to recharge half of a 500 watt hour battery pack (you don't want to go below half for battery health reasons).

>just install an inverter on it and get a battery.
My car is very small, about equal to a modern corolla wagon, no room for a dual battery. Also lucky if I get /out/ in it half a dozen times a year, the install cost/complexity is not worth it. The 50ah lithium box has 240v built in, MPPT solar built in, comes in handy for situations other than car camping, can be removed from the vehicle etc. Just fits my needs perfectly.

>>2841204
used for the batteries numbnuts

the solar panels are basically useless at night without them

>>2841370
>you can only store energy through lithium ions stored in a box
ok boomer
i have 2kw of solar on the roof feeding into a tropical greenhouse (a repurposed walk in closet). theres 500w of heat and 300w of light going while the sun is up. why is the solar oversized? panels are crazy cheap and i dont want cloud cover hindering me. no lithium in the setup and works flawlessly

>>2840559
i have a small solar panel to charge my battery pack/gps while out hunting, it's fine for that purpose. if i tried to stay /out/ longer than 5 days, i'd look into more low/no power options or better off-grid charging options

>>2841371
>using solar panels just to immediate turn the electricity generated into light and heat
so, you really are retarded.

>>2841532
its cheap and works. i cant use the natural light because i need to be able to turn it off at a moments notice and it needs to be 100% humid the whole time. also sunlight where i live has a different heat/light ratio compared to the ground floor of the amazon
the room is also insulated on all 5 sides (not the floor, unfortunately) so there are no windows
also the setup has paid for its self because i use it to grow drugs lol

>>2841538
really not beating the stupid druggie allegations there son, how do you keep your lights on when it's cloudy? What about monsoon season? You're probably just using autoflowers so your grow is retard proof, I don't even know why I'm asking. What if you wanted to keep a fridge going all night, like you already do and pay for from the grid? All it would take is a battery and an inverter.

>>2841538
There's an even more efficient and reliable way to grow plants using sunlight for light and heat.
It's called a greenhouse you dumb drug addled negro.
so yeah, the batteries are an important part of a solar power plan that isn't for someone who smoked themselves retarded.

>>2841624
>cloudy
no problem, if its slightly cloudy my the system produces enough power to run it. i oversized my solar, remember? if its very cloudy i plug it into my home system
>monsoon season
unnecessary
>autoflowers
im not growing weed or anything that i harvest the flowers from
i have black pepper, salvia divornum, psychotria, b cappi, sphagnum moss and an aristolochioides. im also starting an erythroxylum bonsai because i think its funny, but it doesnt really need to be in there. there are a few more on the wanted list but i havent seen them pop up anywhere
>retard proof
my brother almost killed some of them when i was overseas. you know what he did? left the door open overnight
>fridge
why is my fridge revelant? its on the home system and i have no plans to change that
>battery and an inverter
i have an inverter but i dont have a battery. the battery cost just isnt worth it which is why im doing what im doing, it works and has been working for a while

>>2841664
>reliable
not true, i would have to rely 100% on the sun had i had a greenhouse. the way it currently is if the sun fucks me up i can use my home electricity to power it
>efficient
maybe but its working how it is now, why would i change it?
>greenhouse
i said this before but natural sunlight has the wrong ratio of heat and light. if i use the sun to heat it i either let in more light than the plants can cope with or it isnt insulated enough to keep them happy overnight. it will also be too cold if i only let in a small amount of light but insulate it. either way i need to run power in there
>drug addled
i rarely use what i grow, less than monthly. more often i give them to friends or sell them
>smoked themselves retarded
ive never smoked anything that came from that room and have never smoked weed in general
why do you think weed is the only drug plant that exists?

bro lmao what the fuck is this entire post, you literally went and tried to line by line break down why you can't possibly be wrong. Okay dude, so you grow something besides weed, you're basically being retarded by not storing the extra energy in batteries - full stop. Running literally only a grow directly off your panels with DC has got to be one of the most retarded things I've ever heard and you should go around in non anonymous places that get more than a dozen visitors a day talking about how you've created this setup and see how quickly everyone calls you out for being retarded

it was cheap, its indoors so i can visit it without going outside and its perfectly reliable. ive also never had a pest issue (i have to manually feed my aristolochioides) or any fungal problems. whats the issue?
i just posted how i use panels without batteries, i only need power when the sun is up

Dumping to kill competition for a manufacturing monopoly. Also jobs for their workers promotes stability. Money is a gay trick that is worthless since they just type numbers in a computer to make more.

>>2840559
I used that exact model for two months when I was manning a salmon weir. Got all my power from either it or a little Honda generator. On a clear sunny day, it produced as much power as the generator. Barely anything at all if overcast. I thought it was a cruel joke when I had to pack it out, but in the end it was my favorite piece of gear because it freed us from having to ration battery. We had weeks straight where we could run the starlink all day long or charge your phone guilt free. Everyone who manned that weir before us with the generator alone said they could only get an hour or two of wifi and charging a day when they ran the generator. Loved that little thing.

Bring a multimeter with you to test them before purchase.

The CCP isn't "subsidizing" in the western sense of the world.
Instead its a concept where the entire supply chain has to sell inside of China at cost, and the exporter is the only one who is allowed to go above margin.

The catch is that the government might have to step in to subsidize IF there is a economical slowdown, since the margin is the entire supply chain is very very thing, which also means there is a unnaturally fast set of mergers and acquisitions.
And a lot of bankruptcies, since a lot of the companies are not in a export position.

>>2840843
>You have a literal gasoline generator attached to your vehicle just install an inverter on it and get a battery.
The logistical hurdle of that.
Once setup, a good system will keep on going for days. Vs the generator needing to be on/off manually once in a while to avoid bottoming out the 12v batteries.

The catch remains that using a scavenged UPS and a custom 12v system salvaged car batteries or a large pile of cheap 18650 cells is several times more bang for your buck, while the solar panels are still priced somewhat cheap.

>>2842469
I have the skills and knowledge to design and build my own battery pack. I don't have the equipment to build it into such a small and robust package.

>>2840843
>literal gasoline generator attached to your vehicle
From what I was told when I looked into this, an alternator is not designed for the kinds of current loads you will want from a generator. You are going to burn it out very quickly. RVs have 2 alternators : a normal one for the vehicle, and a beefy one for the house.

A good portable private charger solar panel/inverter/batteries goes for like 3k.
1.2 kilowatt, say two 600 watt bifacial panels for 800$, 400 amp hours of batteries (1,200$), and inverter box for 1,000$ Rig it all up like this guy has his.

Throw it in the back of a 4x4 truck bed, and you have potable power practically anywhere in the united states. That's enough to power a minifridge, a t.v., cellular/satellite internet, a tea kettle, water pump, and a small window air-conditioning unit.

I highly doubt that panel can charge that battery with any kind of speed unless it's in the desert being babysit all day so it points exactly at the sun. I've fucked with solar charging a bit for camping and you get at best maybe 80% of the promised current out of the panel. Then you lose some of that to heat to run the charger and heat from the batteries charging. Now you get three more of those panels setups, for eight total panels, you can probably get a decent enough charge you don't have to babysit the thing all day and can enjoy your camping experience.

>>2842468
>Quality has plummeted for them
This. I used to always buy their batteries since they would always have a few more Ah than the rated capacity. Now that they switched to cheaper cells they never reach the stated capacity. Maybe part of that is their switch from 18650s to pouch cells.

>>2840845
yep. I just bring a couple of these with me when I go innawoods

>>2840571
Found the MAGAt

I got a 100mw panel but couldn't for the life of me work out how to wire it to a battery. The power output of the panel was either 12v series or 24v parallel, depending how you wired it. But because it's three phase it just kept tripping the battery fuse.

Is it the wrong battery, wiring, am I missing a part? Does the battery have the wrong fuse? I just don't know.

The panel itself is practical but if you can't run anything off it directly the weight of the battery makes the whole setup ridiculous. Unless you've got a portable HAM kit or something, so its just gathering dust

Cadmium telluride cells contain cadmium. And many cells contain lead for solder (which is not strictly necessary though). If you use nontoxic cells or recycle the toxic ones properly, emissions basically go down to nothing. Of course the firing of coal and oil also emits literal tons of cadmium, lead and other heavy metals, not ot mention various other industrial processes.
