I want solar but cant make it make sense. I dont have a hot water tank, or really anything that draws power consistently in the day. I have no battery for the energy, chemical or otherwise.

Solar panels can be easily manufactured and recycled. All that is missing is government will to establish an industry with 100s of thousands of jobs. Once established it will be literal free energy.

>>103292951
>easily manufactured and recycled.
no and no.
Unless you mean get china to build them and India to recycle them making their countries even bigger shitholes than they already are.
>literal free energy.
Having the government pay for it doesn't make it free retard.

Solar on ones home makes some sense for the times when the neighborhood mini nuclear plant is offline but most people do not own a home. Big solar and wind farms just waste land, toxify the earth, displace trees and animals. Solar and wind power are not environmentally friendly.

>>103292200
The land footprint of solar doesn't matter. Most houses have enough roof area to power them twice over with solar. Sure cities with high rises might need more, but dense areas can use dense power generation like nuclear. Having to transport nuclear fuel cells all across is retarded, especially when the alternative is nearly free local power generation.

You can go on Aliexpress and in 2 weeks have 2kW solar generation with 10kWH storage for $1500. Shit pays for itself in a few months, and you can add to it at any point because it's so modular.

Really? what's the catch? lithium battery gonna blow up? They're banned here in nyc because of people who bought cheap Chinese e scooters a couple years ago and some started fires and apparently lithium battery fire are extremely difficult to put out so fire department made them outlaw lithium batteries.

solar panel door to door salesman guys came recently and gave me quote for like $30k for 6 425W panels and 6 inverters with a power production of 3200 kwh
cant do it anytime soon because the house is old and would need to be renovated first, but it was fun to think about and imagine for a little while

>>103293980
The solar installation companies are ripoffs from what I heard. They take 20-30% off the top.

>>103293980
most of those guys are scammers and will install known defective equipment. There's an entire business model built around removing all that shit right after it's installed. Either have the reputable vendors direct you to a certified installer or DIY.

I work in the power trading business. Our company owns two nuclear power plants and solar power is basically destroying the business case. Nukes aren't worthwhile in summer months because electricity supply exceeds demands and due to grid stability issues, overproduction is heavily penalized by the markets, i.e. negative prices.

>Well, you could just run your nukes at nighttime?
Wrong, they have to be under a constant load and, unlike Hydropower, have very little room to be ramped up or down.

>Just run them from September to March bro
Tell that to the nuclear physicists, engineers, mechanics etc. who earn a shitton of money, since it is hard to source staff for a technology that has been dying a political death for over 15 years. Or rather, tell that to HR.

Solar power is nice and all, but there are two massive challenges:
>Grid support
If everyone wants to participate in the market, especially during peak hours, the grid needs to be able to actually support it.Why would you increase total grid capacity by 50% just for a cumulated 40 hours per year?

>Energy storage
That is the biggest issue. We can't store solar energy in sucficient quantitites yet and it will take decades to get there.
All the good spots for pumped storage hydropower plants, at least in Europe, have already been taken.

>Just build two dozen nuke plants in the middle of nowhere bro

Again, grid capacity and staff issues. Tell a Physics PhD to go live in a desert in Kazakhzstan or something,

all in all, good tech, but nowhere neat as matured as we'd need it to be.

yes i do but i only to my friends and neighbors just small setup like 1.2kw to 5kw, added only 20% markup and labor. i might go full on start a business soon if i managed to get a supply of cheap used EV batteries.

i have a 3kw myself and it paid it self after 3 years, now its giving me free electricity. upgraded to lifepo4 on year 2.

>>103294099
>Nukes aren't worthwhile in summer months because electricity supply exceeds demands
when everyone is using air conditioners??? Summer is normally when demand exceeds supply... Unless you have solar.

>>103294262
There's way more sun in the summer, is his point, which creates an energy surplus.

lol wut? You should have shot the man for trying to rob you.

The catch is that A) You have to DIY. B) You can't just call a warranty or service people if shit breaks down or just sue someone else if you damage something. C) It's not fool-proof you have to actually research which products are good and what the battery arrays and connections are gonna be.

For me, all those were easy. Start small, maybe even a single 12V panel, a controller, and a single 12V battery cell and finally an inverter. Then you can buy one more of each, wire each in serial and you're up to 24V with double the power and capacity and way higher efficiency. Run some numbers, get some measurements, decide if you're happy with the mounting, housing, looks, gains etc... then scale up to your needs.

Companies like to make it seem as if it were some monolithic construction job, but it's literally middle school level electronics with medium-tier DIY know how to get started (would be baby-tier if you're not going on the roof).

The lithium fires stuff is a serious concern for EVs, not so much for houses. Lithium battery fires aren't just random. It's when the battery gets punctured, or when two batteries touch each other without insulation and short and suddenly they get hot enough to burn. You can surely see why that's an issue with all the vibration and potential collisions in a scooter. In a home, as long as you don't rely on the chink temp safeties and instead use your own temperature-sensor and auto shutoff switch the risk is zero outside a fire/natural disaster scenario.

>>103289584
Solar is dead in EU ... or rather, the EU is dead and hasn't noticed yet. I'm too lazy to find illegal work in the US, I'm staying on this sinking ship.
>The solar installation companies are ripoffs from what I heard. They take 20-30% off the top.
More like 200-300%. PV panels, inverters, batteries ... it's all dirt cheap, even if you don't buy the cheapest chinkshit.

Unless you are making 6 figures, DIY everything. You can take two weeks off, buy tools, learn something and still come out ahead.

>>103294515
this

>>103294285
It's fine as long as you charge at night when electricity is cheap and abundant.

>>103294570
My solar panels don't generate much power at night. All the glowies here are not enough to trickle charge.

>>103294515
>Solar is dead in EU .
On the continent, solar panels are now so cheap that people use these as fences. Chinese manufacturers are desperate to unload their stock.

It's crazy how dirt cheap solar is becoming. So many durable high-output panels on the market right now. Setting up an off-grid power setup has literally never been easier.

The real robbery is salesmen trying to charge people 20k for solar installations, and clueless boomers getting suckered into paying for it.

>>103294514
Or you make an insulated battery box with a power vent and a backdraft damper and put it in the yard (or just use two power vents in push/pull, they have backdraft dampers build in). Off gridders perfected all this stuff in the age of lead acid, because the acid was shit to have in your home too. If the battery burns down it just scorches some earth.

>>103289584
Hmm, seems like something i'd enjoy working on. Carefully place each tile of the grid. Then monitor it through software. Setting up monitoring servers/systems for remote control and stats. Sounds nice for autism. Also get some sun on the field.

>>103294262
I don't live in a 3rd world country, so I wouldn't know about AC. But clearly, you have no idea of how the energy market works and what the seasonal changes to the vertical load on the grid look like. Power consumption in colder months is higher than in warmer months. Outside temperature has a strong (negative) correlation with power spot prices.

In any case: Dynamic residential customer pricing will have to be part of the energy transition to renewables. Which essentially means, AC will be free in the future, since you're only going to use it during times of excess solar radiation. Consumers will have to be incentivized to use the excess power from solar generation and penalized during seasons with less radiation. I.e. charging your EV will be virtually free (or you'll even get paid for it) in summer and painfully expensive in winter. And the only way to incentivize someone to do something is through their wallets. However, this requires a substantial upgrade in grid infrastructure.

>>103294515
>Solar is dead in EU

Check out EPEX (European Power Exchange) day ahead spot prices in summer. Negative prices up to -200 euros/MWh and it's all from solar.

>>103294901
The problem is that in my nation all the money is going into tard wrangling of refugees and elderly boomers now.

To increase solar further we need decentralized storage (eventually long term storage, but plain old batteries are good enough for now) with localized spot markets so the storage is used effectively.

Government and electricity companies are doing exactly dick ... wait that is not true, they are actively holding back batteries. Solar is running into the dead end of negative electricity prices and poorly controlled currents on the high voltage grid. It's fucked.

>>103292184
Start saving car batteries

>>103295087
The worst things is that they are all complaining about the capacity of the voltage grid. When the capacity would be completely fine with efficiently used distributed storage.

The only money getting spend is on building out distribution, which isn't actually needed. It's completely fucked.

I'm all invested into solar materials, because this is going to be absolutely massive by 2030.
Keep eyes on Brazil, they're going to be an absolutely gigantic solar producer and lucrative as fuck for anyone invested in there.
Bankers are throwing money into their solar sector hand over fist and for some reason people aren't paying any attention to this.
Sand batteries that store heat are going to be responsible for grid level energy storage. That's the most viable way to do it and it's going to revolutionize the renewable sector, making it infinitely more viable.

t. knower.

>>103295122

Perovskites are finally going to kick that to the mid 30s within a year or two and they're going to drop solar panel production costs to 1/6th of what they are.
Small indoor perovskite cells are already going into production, so this tech isn't speculative anymore, but one hair away from mass production.

how difficult is to DIY if you have basically no knowledge of electricity? is it just connecting cables?

also, why the fuck haven't regulators made using batteries to store, say, 1/3 to 1/2 the energy production from solar PV a requirement?

>Sand batteries that store heat are going to be responsible for grid level energy storage.
Only with thermal driven heatpumps, otherwise the round trip efficiency is disastrous simply due to COP<1 heating.

Everyone is installing electric heatpumps now. How many people will be left to bury a sand battery in their yard with an entirely new heatpump?

lmao so what if we cover Texas in solar panels? That's like 4% of the land, who cares

>>103295575
>is it just connecting cables?
No, you need to add a new group to your fusebox. Pull the right cables for code, etc. If in America probably need to get it code inspected when done (if you live in a country where DIY electrical work is illegal, emigrate first).
Even when the inverter is disconnected from mains, a PV panel string starts outputting high voltage the moment it's in the sun. So if you do something stupid, like opening the inverter to connect some wiring after the string is connected you can still kill yourself.

At a minimum don't forget, touching two conductors with two hands is what will kill you.

>>103295608
>You should know the basics of electricity
right, I'll grab the books and relearn, because I never got the basics right and also never practiced anything

>and wiring
what's so difficult about wiring on itself? guess I could just watch a bunch of video tutorials on yt for that.

thanks anon
btw, are there forums where I can ask questions about inverters, MPPT and stuff? I've been doing a little research, but most resources are in english and I live in chile. we have different standards here (220V, 50Hz) and I have no clue who to ask in my country...

>>103295889
>If in America probably need to get it code inspected when done
I live in chile, and from what I've read, yes, I could DIY and get it inspected later, but that depends on multiple factors (offgrid vs ongrid, for residential vs commercial use, what type of commercial, etc.)

>PV panel string starts outputting high voltage the moment it's in the sun. So if you do something stupid, like opening the inverter to connect some wiring after the string is connected you can still kill yourself.

Brazil can export it to the US if they want, but they don't really need to ship it anywhere.
They're an emerging economy that's going to consume a shitload of energy, as they industrialize more and more and when their quality of life goes through the roof.
It's going to be one of the largest growth centers during the next economic cycle, where as Europe and US fall into their lost decades of slowly eroding economies that aren't competitive and are drowning in debt.

>>103295696

I'm talking about easily available grid level storage, which at the moment is practically impossible due to how shit and expensive lithium is.
This is a game changer in making intermittent renewables actually viable.
Sand energy storage is 1/10th of the cost of lithium, stores energy for days and is not volatile at all. It can be installed anywhere and materials are fairly easy to find.

>>103292200
are you a yuropoor or just stupid. It's free energy.

I put a small solar array on my roof this year, 2.2kw with 2.4KWh of storage for less than $1500.
Wired all the small loads to it like lights, fridge and small appliances while the big stuff runs from the grid, it cuts my bill in half since I don't hit the power limit anymore, but more importantly I still have power when there is a blackout even at night.
My ROI seems to be like 3 years, after I'm gonna upgrade to cover the entire house.

>>103296178
Heat in sand batteries don't tend to be used for electricity regeneration, round trip efficiency is terrible unless you have an use for the waste heat.

what is great about solar installation is there are actually tons of jobs in other countries
if you are smart about it you can live in a dozen countries without a highschool degree
and make good money

>>103292200
I love those retarded infographics that immediately tell on themselves because they can't stop posturing about how they are the correct, down-to-earth right wingers who just so happen to support existing power industries and everyone who disagrees is just a naive idealist.

what, stack it up on barges and ship it across the sea? My point is that electricity is very hard to move over long distances without massive losses. If you're going to build out power generation, you might as well build it as close to where it's going to be used as possible.
