Is solar energy worth it?

Seems like a huge fucking scam.

If it really does generate energy and you can cover your house in solar panel and disconnect from the grid and save yourself $100+ a month, everybody would be doing it and getting returns on investments 1 year later.

What do you think?

i love how the US is ruled by complete morons
>>
it's a total scam but if you live in a state where you can plaster your rood in them and have free energy because of the retarded subsidies they are given you're stupid not to do it
>>
>>106468253
The energy providers here in Australia are complaining because solar produces too much energy that's being forced back into the grid. This dude just wants kickbacks from coal mining companies.
>>
>>106468253
If you can get good subsidies it's definitely worth it. But for a country/society it's currently only worth it if you actually use the panels for most of their rated life. But what happens in practice is that the panels get replaced or removed (and almost always end up in landfills) before they actually pay off financially or environmentally.
>>
Solar obviously isn't a scam. However this depends on where you live HEAVILY. Not just regarding the weather, but also even more importantly regarding all your local laws, how your power company handles off distributing electricity, and the subsides. Then there's stuff like your roof condition, how long you plan to live in your house, if you ever plan to do any kind of renovation for your house, what kind of energy do you actually use for heating your home...

There's a lot to take into account.

idk, I built a shack in the woods and solar/batteries are the only source of power and it works ok so far. runs my internet, lights, a fan, gaming pc, and stuff like fridge and hotplate for food.
some point im going to get air conditioning too, all this started from nothing, i have like 6000usd into the solar setup so far

ruled by morons and still better than whatever shithole you're from. If you're American, you know where the door is.

Most people don't own their rood anon

Wind and solar don't work.

It's time for CLEAN coal.

>>106468253
Most people either:
- Do not have the capital to invest in a satisfactory set up
- Do not own a house
- Cannot think far enough ahead to see the beneifts
- Live in a cloudy country where it doesn’t work as well

Pretty much anybody with the money is installing solar even in places it doesn’t make sense, to the point that in some places grid operators are getting annoyed about it because there’s too much solar generation on the grid, and it can throw things out whack.

It's the only thing delaying our collapse now. They can only accomplish like 70% of the evil deeds they want to do since they're too incompetent for the rest.

$6000 for solar panels/batteries? How much would the electricity cost you per month if you'd have bought from the grid? Seems like it'd take a while to pay itself off.

Might've been cheaper just running a generator.

Pervoskite tech is coming to the market at the moment and it blasts right through the current theoretical max ~23% polysilicon efficiency limits.
And since it's a chemical based system instead of a crystal, it means you can basically spray it on surfaces if you feel like it.
It even works really well indoors and will power everything that currently needs batteries, so your remote will never run out of batteries again.
Biggest weakness of solar is energy storage and that problem is currently being solved with heat based energy storage into sand, which is cheap as fuck and also safe.
Solar is going to be bigger than ever before due to these developments and that efficiency gain is going to make it viable everywhere.
It's also cheaper than the current tech.

Perovskite is only currently doable in small scale. They still need to fine tune it so it doesn't use lead, gets damaged by moisture/heat/UV.
>>
The short answer is that, theoretically, a surprisingly small percentage of the Earth's surface—roughly 0.21%—would need to be covered with solar panels to generate enough electricity for all human civilization today.

That's a square of about 630 km per side (390 miles), or an area slightly larger than Germany.

it would have costed $35,000usd to have a company come out and install power poles/lines and install a transformer and distribution box.
it paid itself off the moment i turned on the bms.
I ran a generator for a grand total of about 3 hours before I had some solar up and it's been going for like 7 months now.

This is why AI sucks and AGI is bullshit. Chris Wright is the Secretary of Energy in the US. He's an MIT graduate, and has a degree in mechanical engineer. He was the CEO of a hydraulic fracking company prior to being appointed.

I think he knows a thing or two about energy. It's not 0.21% of earth being covered in solar panels, but actually 500%!

It's very very close though.
It's already starting production for indoor use and the outdoor use is basically around the corner.
The lead free chemistry is already more or less figured out and just needs a bit of adjustments to get the efficiency up from 17% to +20% and it's basically good to go for mainstream markets.
Give this tech a year or two and it'll be commercially viable.

What the fuck

>>106469398
All politicians should inhale coal fumes 24/7 for a month to prove it's clean.
>>
It would be worth it if the government weren't such faggots about it. In Melbourne, Australia the government forces you to feed your solar power back into the grid, hooking up everything to a battery is extremely forbidden and they will come and throw you in gaol for "unsafe" electrical. So instead of supplying yourself with electricity you have to pay like $100+ a month to be connected to the grid and then are forced to use the grid power at night time with peak power prices while they pay you like 2c per 10kw for the power you generate during the day.

Solar would be a great way to decentralise. I'd happily buy low power goods, chest freezers and whatnot, just to not have to fuck around with energy companies.
>>
>>106469398
coal is literally obsolete in the USA and cannot compete with pipeline gas in any respect. It only continues to limp along due to existing infrastructure and subsidies.
>>
>>106469797
it only continues to exist because the current administration is retarded and wont let go of it
