Solar panels not as green as you think

[Into the Night]

The worst offenders are the thin film panels used in large scale and industrial applications. They contain many highly toxic chemicals including cadmium telluride (CdTe) and copper indium (gallium) diselenide (CIS or CIGS).

As far as 'toxic' chemicals goes, any chemical, including water, can be considered 'toxic'. Material Safety Data Sheets have a purpose, you know.

Sure they do. Here is one link, not hard to find many others: https://news.energysage.com/recycling-solar-panels/

You really ought to read the links you use.

This is a news article touting the future need to recycle solar panels. None of these 'solutions' are practical.

Reuse won't work. The panel is being discarded because it doesn't work anymore.
Obtaining the rare earths from them is basically a joke. We are only talking about a very tiny amount that is embedded in the silicon crystal itself. We are literally talking molecules of the stuff here.

You can certainly grind an old panel into sand, maybe use it for wherever else you would use sand, but that's about it.

STFU you dolt. All this beautiful science going on in the world and muttonheads like you and Primaassstank spouting off
as if you know anything at all or as if anyone cares what the fuck an embarrassing social misfit addicted kook thinks.

You don't get to tell anyone to shut up. You are not the king. Even if you were, fuck the king.

You have no idea what science is. It is not even being discussed here. This is about fascism, not science.

The technology is getting better and better. The future is in alternative energy. Staying with coal will put us way behind and not a future commercial power.

What technology is that, dude? What sort of magick are you looking for here?
Define 'alternative energy'.

Coal is cheap. That means there is plenty of it. You don't get to dictate energy markets.

I doubt you will get much out of solar panels at the 30 year mark if they still work, they decrease in efficiency at least 10 percent or more after 1 decade and even more after that.
tHE AVERAGE HOME NEEDS 23 KV ELC A DAY THAT. with A SMALL RESERVE THATS 4 TELSA POWER WALLS ABOUT 40,000 INSTALLED, AND OF COURSE YOU NEED TO ADD IN SOLAR PANELS TO THAT. yOU WOULD NEED AT LEAST 40 KV OF SOLAR PANELS TO KEEP YOU CHARGED AND RUNNING THATS GOING TO RUN YOU 40 G OR MORE.

iT TAKES A LOT OF SOLAR AND WIND PRODUCTION TO POWER A HOUSE . iT WILL WEAR OUT , A GOOD SYSTEM WITH PLENTY OF POWER WILL COST YOU AT LEAST 80 G .

untilL THE BATTERY TECHNOLOGY AND PANEL TEC CATCH UP SOLAR IS REALLY ONLY GOOD FOR BACKING UP A HOUSES POWER TO EMERGENCY LEVELS NOT 100 PERCENT USE. YOU NEED A LOT OF SPACE FOR A 40 KV SOLAR SYSTEM .iTS A VERY GOOD THINK FOR NEW BUILDS AS YOU CAN GET A TELSA SOLAR ROOF FAIRLY CHEEP ON A NEW BUILD .

It ain't cheap, either to build or to maintain.
There is no such thing as a 40kv solar installation. Unit incompatibility error.

You did make me laugh BB. I'm sure ItN and T.A. will be along shortly to correct your idiocy in not knowing the basics of electricity.


But in case they don't show up -
The majority of the homes in the US are not wired for anything more than .22KV (220 volts). A single solar panel with the right buck boost transformer would be able to give you 23KV but it really wouldn't do you much good since nothing in your home is rated for anything over .6KV and the amperage would be extremely low. Power isn't voltage.

Mostly right. Homes are typically wired biphase, where you have 240v at the service entrance, and is split along a neutral wire to provide 120v on either phase. Electricians try to balance the loads on each phase more or less equally when they wire the panel.

Both the transformer feeding your house (that cylindrical thing hanging on the power pole) and the service entrance itself are rated to a maximum wattage, sometimes referred as KVA (kilovolt-amps). Since P=IE, this terminology is a reasonable one.

You are correct. Voltage is not power. Neither is current.
Voltage is like pressure in a pipe. Current is like the flow. You gotta have both to do any work.

Ohm's laws also work with plumbing.

What is wrong with you? You just type insulting and stupid things over and over. I do not want to sink to your level on a debate board. You make it into a childish insult board. Do you think you are adding anything to the topics? I assure you, you are not. Try and do better.

Kettle logic fallacy.

you're lower than the lowest possible level, you fucking totalitarian lie-bag.

Your the one who dont know much dumb ass .

"Don't" is a contraction. There is an apostrophe in it. The correct word is "doesn't".
Since you are starting off with a spelling error, let's see where this goes...

The average 2000 st home in america uses 32 kv of elc a day .

"America" is a proper noun. It is capitalized. Unit error. kv is not a measure of power or power used. Voltages are not consumed.
According to Energy Adminstration, a typical home uses about 30.1kWh per day. That can be in the form of 30kW for one hour, or 1.25kW for 24 hours.

That means to your solar panels have to produce more then 32 kv. Enough to cover use and charging.

Solar panels do not produce high voltages. House wiring is not designed for anything over 600v. Most of it carries 240v or 120v circuits. Most are fused with 15A or 20A fuses, depending on the gauge wiring used. A typical toaster draws about 650W, or 5.4A at 120V. Toasting something for an hour (ewww...burnt toast!) will consume 650wh.

So 8n reality to have 100 percent solar power say 40 kv or 40000 watts . 1 kv is 1000 watta.

A kilovolt is not watts. Unit error. 40kv is not 40kw. 1kv is not 1kw nor 1000 watts. I assume "watta" is a typo, but since you have numerous spelling errors, I'm not sure.

You assumption that 1 aolar panel is capable of proving that kind of energy is pure stupidy.

I assume "aolar" is "solar". "Stupidy" is misspelled. It is "stupidity". Unit error. Kilovolts is not energy. Not even watts is energy. Energy is measured in Joules, which are directly convertible to watt-hours.

Most homes in the us can use thier roofs but your not going to produce 40000 watts aka 40 kv on a 2000 sq ft roof.

It is spelled "their", not "thier". Unit error. Watts is not volts.

You forget that home solar systems are 12 volt and rated in watts.

Nope. Home solar systems use inverters to produce a nice clean 120v. Solar panels themselves produce a widely varying voltage, depending on how much light is striking it. The total system maximum capacity (not a measure of the power actually produced) is rated in watts. Drawing more power than the system is designed for will permanently damage the system. Fuses help, but they are not fast enough if the load is applied suddenly.

1 kv is 1000 watts.

Unit error. Voltage is not watts.

You need a good bit of solar panels to generate this. My home is 2500 sq foot and wont provide enouh room.

"enough" is not spelled "enouh".

You have numerous unit errors and spelling errors. In my opinion, it is YOU that doesn't know much about either electricity OR English.

The average home doesn't use 32 kv. The average home uses 220v with much of it split up and delivered as 110v.
1kv is not 1000 watts, it is 1,000 volts. 40000 watts is not 40kv it is 40kw. Watts are calculated by multiplying voltage by amperage. Watts can't be interchanged with volts. Over time 40,000 watts would be considered 40kwh when that much is delivered over an hour.
Voltage is easy to change. One need only run it through a transformer of some kind. It's how 110v becomes 12v or 17v can become 32kv. When you change the voltage the wattage doesn't change but the amperage does.
You are using the wrong terms.

Most home professional solar systems that would be installed on a roof are 17-40 volts and produce at the rate of 320wh to 360wh at peak production which they won't reach for the most of the day. It would be silly to have them as 12v systems since the wire size is based amperage. The higher the voltage the less amps for the same watts. 1200 watts at 120v would be fine with a 14 awg conductor but 1200 watts at 12v would likely require at minimum a 4 awg conductor.

The average home uses about 28kwh per day on average. From January 1 - Oct 2, I have produced 7.9mwh which works out to an average of 28.7kwh per day. At the same time, I have used 6.3mwh. The area of my solar panels is only 422 sq feet. Your claim that you don't have enough room on a 2000 sq foot roof to produce 40kwh is bullshit. The only reason you couldn't produce an average of 40kwh is because you must have obstructions blocking the sun from the panels. You have more than enough room to produce an average of close 60kwh just using the south side of your roof.

Of course, NOTHING is being produced at night. Solar cells typically produce less than a volt. They have to be wired in series to get higher voltages, just like batteries. I might point out that this is piddle power. It's very expensive, watt for watt.

Your the one who dont know much dumb ass .

You're off to a bad start:

The correct spelling of "your" in the way that you used it here is "you're", as that is the contraction form of 'you are'.

The word "don't" is a contraction (for the words 'do not'), thus it has an apostrophe in it. -- You didn't even use the correct word here, as the correct word when the subject is 'one' is "doesn't" (does not).

The average 2000 st home in america uses 32 kv of elc a day .

"st" is not a unit of measure. I think you meant to say "ft²" (square foot), as in a 2,000 square foot home...

America is a proper noun. In English, proper nouns are capitalized.

"kv" is not a measure of power used. The unit of measure you are looking for is kWh (kilowatt hours).

That means to your solar panels have to produce more then 32 kv. Enough to cover use and charging.

The word "to" should be 'that'... 'that' is the word that you were looking for.

"Enough to cover use and charging." is a sentence fragment (not a complete sentence).

The "kv" error has already been noted.

So 8n reality to have 100 percent solar power say 40 kv or 40000 watts . 1 kv is 1000 watta.
You assumption that 1 aolar panel is capable of proving that kind of energy is pure stupidy. .

Okay, the rest of it speaks for itself and is further QED of what you (don't) know (at least with regard to the English language).
