Extremely informative video. The whole process is much simpler than what i thought. It would be nice to make a video about how much on average the construction of such plant costs and since you mentioned Silicon is so abundant, does that mean you can build it almost in any country in the world?
Silicon is the second most abundant element on planet Earth (oxygen, by the way, is the most abundant). And silicon makes up around 27.7% of the Earth's Crust. This is basically why we have sandy beaches. Because the rocks are, as mentioned, around 27.7% silicon (on average - some rock types more and some rock types less) and then the sea water - tides rolling in and out, and crashing waves against the coastal rocks, etc. - are gradually eroding those rocks away. (Think about rounded pebbles on the beach. They used to be perfectly rocky and irregular in shape, but the water has been eroding them and rounding them off over time, until we get perfectly smooth and rounded pebbles.) The tiny particles of rock are then washed towards shore by the tides. And so we get sandy beaches - which are actually a mixture of things, but as there's a lot of silicon in the rocks that make up the Earth's Crust, then there's also a lot of silicon in that sand, because it's just those rocks all crushed up and eroded, into almost a powder - washing up to the shore and deposited there. So, yeah, there's an abundance of silicon everywhere. Second most abundant element on the planet. Of course, there are places where it's way easier to obtain than others - there are silicon mines, where it can be dug up and processed easily - so how economic it is to do it in one country versus another does vary... ...but to directly answer the question you asked, yes, you could technically extract and process silicon anywhere on planet Earth. Basically, it's just rocks.
@@klaxoncow but it requires lots of energy, compared to how much it yields. You can hear it in the video: a solar plant can produce the energy it needs to manufacture itself again in 2 years… probably if we choose low quality raw materials, it would take even more energy to purify and distill

Good Luck for the plan to start such a projecct in Pakistan! Starting with module production ist an easy step - solar cells, wafers and silicon can follow.
Behind each step in manufacturing a solar panel/module, there was coal or fossil fuel energy used to manufacture a finished product and then when it's done, they magically just call SP a ''green' energy LMAO
Well, you could easily use solar electricity or solar produced Hydrgon for the processes. At the end it is important to understand: photovoltaics will produce more than 30 times the energy (from the sun) compared to the energy used for production of the solar module!
@@Ericrueland007 Yes I agree, we could but watch how expensive that SP will be in comparison to SP produced by cheap coal&FF energy. I'm not against SP or any green energy for that matter, I just believe we are being manipulated into believing how green energy is green! It's very hard to find carbon footprint info on SP or wind turbine etc. To some extend (debatable how much), green energy is just a big hoax!
@@kolobara08 on minute eleven, you can hear that it only takes 2 years of solar power to manufacture the same solar plant again. If the lifespan is 25 years… that means that you get 23 years of carbon-free energy.
yes, of course. We have already solar installations with more than 2,4 GW of rated power. During bad weather conditions you need energy storage. That could be solar hydrogen or battery power (maybe TESLA batteries as a second life).
The solar panel manufacturing is connected with the lowest invest needed. For a capacity of 100MW per year the invest for a solar module fab (you have to purchase the glass, laminate and solar cells) might be in the range of 15 Mio US $. on greenfield. But invest in solarmodule plants is just around 0,5 US$ per Watt installed. Giving a electricity cost of app. 0,05 US$ in sunny regions.
Sand? Lie. It's quarts not sand because sand is contaminated with other elements. It's mining that provides the quarts that is crushed and heated with coal to crystalize
It is the different cell technology used. Standard (traditional) solar cells are p-type. Using Boron for initial doping of the silicon - making the silicon wafer p-type (or with a majority of holes not electrons for conductivity). The phosphor is used to make the p/n-junction or diode in a standard cell. For n-type it is the opposite: the silicon wafer material is doped with phosphor and the layer is made of Boron doping. At the end: n-type is a bit more complicate to manufacture, but gives higher efficiencies. Therefore it seems to be the near future...
@@Ericrueland007 Thanks for your reply. I did a lots of study on it. Following are the advantage of using N-type over P-type cell. 1. LID losses will be 0.6% inplace of 2.2% . 2.Temperature derating losses are very low in N-type as compared to P-type cell. These results are based on final yield analysis report from PVsyst modelling software using Third party verified .Pan files.
“You can use any type of sand”. No, that’s a lie. Almost exclusively very pure silicon ‘sand’ is used. Not from the desert, but from these kind of quartz mines. The man just said it himself, you need 99.999999% purity.
@@Ericrueland007 It is, that's why chip prices are spiking, the silicon they are made out of is made from this same sand and the stuff is becoming much harder to come by ALREADY!
they only show where the silicon goes and not the carbon, it also appears that you need an equal volume of coal sorry carbon to complete the process......hmmm. How green is this?
Well, it is correct. The production of solar cells and modules produce CO2 emmission. A scientific calculation shows: app. 50g of CO2 per kWh electricity. But coal produces 1.075 g of CO2 per kWh - that means a reduction by a factor of 20! source: www.ise.fraunhofer.de
Am interested in A full Integrated Solar Fabrication as a business where can i start from engaging with GP Solar Solmic been trying to find website but it keeps taking to other sites
You can contact the equipment manufacturer in Europe or Asia, but the industry reached a level of maturity, where starting from zero is very tough to reach comparable manufacturing costs. The price for solar modules are at a level of 0,2 - 0,35 Euro / Watt. Producing 1 - 2 kWh/year reaching full levelized cost of energy of 0,02 - 0,08Euro/kWh - 100% competitive to all other sources of energy.
Yes, but they pay off their carbon debt pretty quickly. I think it takes like 2% or 3% of their service life to hit the break even point where carbon released equals carbon saved, and after that it's all gravy from a climate standpoint.
They also consume petroleum, which is used for the plastic backing of the PV cell. I honestly don't understand why we haven't been producing PV cells to be as recyclable as possible so that eventually we don't need to produce any more new ones, and just recycle the old ones every 25-30 years.
@@smugless191 Recycling of most of the material IS DONE. But solar modules have a minimum lifetime of 25 years, which makes it still no big business. But it will come. And plastic is only less than 5% in the module.
@@williamdobbins7556 you are right - the energy payback rate is much more than 20. and steadily increasing. with latest cell/module technology the reach of more than 30 times is there. As well lifetime was originally expected to be 20 - 25 years, but in fact it can be more than 30 years.

This is rubbish, Quartz and coal (around 10 tonnes) are used to make solar panels, NOT sand or silicon as you put it. The raw material for the solar panels is coal, which has an average life of 11 years. This means that 11 tons of coal must be burned to make a solar panel - that’s about 3000 pounds! The production process uses high temperatures and pressures.
Informative video indeed! But actually I have been given a project in which i have to make a solar cell. But i think it's not possible for a student because resources are not available.

Actually I do not recommend to produce a silicon solar cell as DIY project. You need chemical processing equipment and high T processes, which are not able to run DIY. Other low-efficiency concepts (like a dye sensiticed solar cell) are possible: ruclips.net/video/17SsOKEN5dE/видео.html - but don't expect efficiencies > 5%.
@@Ericrueland007lot of thanks for your precious suggestion! you are right but actually the difficulty is that i have to use it in a circuit like on a breadboard i have to attach it and then to show that I can use my solar cell in a circuit as a voltage source and circuit is giving it's respective output so perfectly.

Yes I'm pretty sure that's why this factory has its own solar grid. He even mentioned that you get about 12x more energy produced by the panels than you put in. Of course, it takes carbon to produce them and emits CO, which is not terribly good for the atmosphere.
Hi Amin - no, the electrons are inside the silicon. The sun (photons) carry energy, this energy is catched by the photons. Now the high-energy photons can "produce" the electricity... and are transported as currency through the cables of the solar module.
CO and CO2 are the products of this process. Nevertheless the solar electricity produced with the solar modules made are able to prevent CO2 emission of the total production by a factor of >30 times
If that really bothers you tell the government to make them flare it off. All you'd have to do is have a flame at the vent and then it would oxidize to CO2. However... does anyone care? not really. the generated CO would probably oxidize naturally eventually anyways as it is not as stable as co2.
@@richardjohnson884 Yes--anyone who likes chemical reactions to be described accurately cares. This is a scientific explanation so accuracy is important. The chemical equation accompanying the description clearly shows CO being produced, not CO2. If some CO2 is also produced that should be explained and a separate chemical equation shown.

CO and CO2 are the products of this process. Nevertheless the solar electricity produced with the solar modules made are able to prevent CO2 emission of the total production by a factor of >30 times
If that really bothers you tell the government to make them flare it off. All you'd have to do is have a flame at the vent and then it would oxidize to CO2.
However... does anyone care? not really. the generated CO would probably oxidize naturally eventually anyways as it is not as stable as co2.
@@richardjohnson884 Yes--anyone who likes chemical reactions to be described accurately cares. This is a scientific explanation so accuracy is important. The chemical equation accompanying the description clearly shows CO being produced, not CO2. If some CO2 is also produced that should be explained and a separate chemical equation shown.
@@Ericrueland007 but what about when they are no longer functioning? Are they recycled?
