I'm a big fan from Lebanon, I love your videos Matt! Solar saved our lives! We have 1 to 2h a day maximum of grid coverage so we just installed a 4kw solar setup and just cancelled the government grid. We're saving a ton on bills, spending it elsewhere and living fully on green power :) The setup is small, so we manually regulate things like on hours for fridge, etc..

[@fuzzy-02]

@@mickmccarthy8925 there is no urban area or country side, the nation is very small but very mountaineous. I live on 420m elevation with a lot of humidity and clouds. The only intense power sucker is the fridge, which we turn on at varying times. During summer, clouds are minimal and the 4 520W panels are working a lot of the day, so we keep it on from 6 am to 7 pm. In autumn its more cloudy and less sun so the fridge goes on from 7 am to 6 pm. I winter its very dependent on the weather, but at worst we turn it off an hour or so during its on hours. For heating water to bath and shower, we have a gas setup, its cheaper then electricity around here. We're also very careful with the batteries (2x250A) and the load. Aside from the fridge we really don't have anything that sucks power with high amperage. My gaming pc is on the lower end, I can keep it running pretty much always. Lastly, the trick to solar, I found, is to minimize consumption when the sun is setting, where the panels are barely charging and turning on anything besides lights and wifi make it stop charging the batteries. This is about a 1h period here so we just let it charge. Perhaps it is illogical, but that's just how I handle all my electronics: don't overstress them and keep them happy. I have an old laptop with an i3 2nd gen, 4gm ram, and an hdd, its terrible and should have died years ago but its still kixking even after 11 years. Same with solar, its a game of load balancing

[@fuzzy-02]

@@ktefccre sure. My house is full of LED lamps, barely use 20W at most. 2 250A batteries and 4 520W panels have been doing a great job. Although it gets frustrating during some winter days with full on cloud and no heat from the sun, we never pass a day without lights and a working fridge. Heating for the shower is gas-powered, so the only power suckers in the house that impose a heavy load are the fridge and the iron (for clothes). Fridge runs an average of 8h, 12 during the summer, 6 at worst during winter. I live in a very humid area with a lot of clouds too. If I lived in a country side with minimal Cloud, solar would be a blast! Though it would be more terrible in the freezing winters Id assume too. So yeah, the biggest power consumers in the house are iron, fridge, washing machine (forgot to mention it in the other comment), and then my pc at 100W at most. 1V in the Inverter's battery charge panel is equivalent to 500 Watts, since we have 2 250A batteries (1v x 500A = 500 Watts) That means the Pc at very high load might take a singular watt in 5 hours. On a regular day with 8 hours of sun light, you can say we have about 3 volts or 1,500W to work with. You might think its nothing because of the fridge, washing machine, etc, but these don't use much power in practice because we run them during sunlight hours, so the pressure is offloaded from the batteries. Idk if my explanations make sense but its a humble setup with minimal consumption. The most important factor is to keeo watch on things and take care of your appliances

Regarding the Larq promo: real UV sterilizers for water keep the fluid in very close proximity to the bulb (a few mm is typical for aquarium or domestic water units) because sterilization efficiency drops off very quickly due to the water absorbing the UV. It strikes me as highly implausible that the LED in this thing is going to be sanitizing or sterilizing anything in any meaningful way. Perhaps a completely empty container, maybe. But a 6 inch tall column of water? Doubtful.

Why not talk about the large volume solar panels and why everyone buys those instead? These cadium panels are nothing to get excited about. And theres a reason why solar farms and residential systems use silicon. I just dont get it. I dont see any real benefit here

[@MrArtist7777]

Having worked in the utility silicon solar industry for many years, I can assure everyone, CdTe won’t catch silicon as it’s efficiency will always remain much lower and cost, much higher, and silicon modules are starting to overlay transparent thin film over silicon modules now, called HJT cells, to offer: 32-40% efficiencies. It’s all about price in utility modules and silicon is almost 1/2 the price of CdTe. Cadmium modules have been saying for many years that they’ll increase efficiency, and it doesn’t happen.

[@blablup1214]

Yeah that is the missing important information that I was waiting for. Just looked it up. They cost a little less but are less efficient and need more space so that their output per $ is smaller . ChatGot got found the numbers CdTe , 0,07 USD per kWh silicon, 0,06 USD per kWh

[@ramblerandy2397]

Got to admit, I'd never heard of CdTe panels before. The only application I'd ever seen for Cadmium, over Silicon, was in the light meter of my old Pentax ME Super film camera. And guess what, it was a superior meter too. I guess the point is, Silicon is so damn plentiful, and latest Perovskite added in tandem development models are pushing well past the Shockley-Queisser limit, as far as 43% in the lab. Yes, Perovskite is that super material that let's itself down by quickly degrading in sunlight, of all things, but that is quietly, if slowly, being solved. I guess CdTe will find its place in the mix. It looks like a great alternative and there is certainly a vast market to fill. Incidentally, when you say 2nd most common panels, I'd love to see a bar chart of the percentages.

[@anguscampbell1533]

Can CdTe panels be used in tandem with Perovskite Panels the same manner that Si PV Panels are? Would this improve their efficiency? Have CdTe panels been used as an onboard charging system in vehicles? If they are "thin" then the weight should be less than Si PV Panels making them better suited for onboard charging of batteries in EV Vehicles. This could have applications in Electric Trucks with the roof of a truck trailer covered with panels and that could contribute to the recharging of the onboard battery.

[@anguscampbell1533]

One would guess the weight of CdTe is more because of the atomic weight or less because it is thinner?

[@KyleMackenzie]

I like that it diversifies the supply chain for solar panels so that if there is disruption in silicon production we have mature alternatives.

[@artboymoy]

How easily can cadmium telluride break down back into it's toxic elements? When I hear people say they're afraid of panels breaking and leaking toxic material I thought they were crazy, but then we have panels like these, and you have to wonder if this is what they latched onto to drive those concerns. I'm more for silicon with perovskite layer to boost efficiency.

[@dianapennepacker6854]

A UK manufacturer is already making a pervoskite/silicone solar panel with 24% efffiency in the real world. 28% in the lab. "Just have a think" just released a video on it.

With advancing super capacitors we may one day be able to store electric from lightning as static energy.

[@Warp9pnt9]

Initial thoughts after the intro: Cadmium is a real nasty substance and also rare, so we shouldn't really be using it in tech and mining and disposal chains that risk environmental contamination. Maybe if recycling chains were mandated by law to be maintained y the companies fabricating tech, and if severe (jail, hundreds of millions or billions in fines) penalties for improper disposal, and cleanup crews (storm or disaster damaged arrays) help as well, then maybe ... but I still think we should focus on tech that won't poison us so readily.

[@Warp9pnt9]

After video: Nice to see the recycling loop is mostly closed. The bigger concern remains the lower efficiency. There might be niche applications for mobile home or trailer installs where the benefits of lower weight saves fuel that would equal of exceed the amount of additional fuel needed to move more efficient but heavier silicon panels, as well as extra fuel burnt in CdTe systems to run a generator to make up the difference. This would be use-case dependent, where the difference between panel weights is significant compared to vehicle weight, as well as the frequency of moving the vehicle.

[@michaelmartin9022]

​@@Warp9pnt9CIGS panels are also light, tough and truly flexible (never flex the "flexible" silicon panels!), though less efficient. Also they're expensive but I have it on hearsay that they could be cheaper, if they had higher production runs. Only one company really sells them; BougeRV. They also seemingly got off to a rocky start with some other company that sold them first getting a bad batch, witj crappy glue, that delaminated.

So you missed the part of it not being toxic when mixed ?

[@jamesgregsy]

I really like seeing some diverse technologies and this seems like a really relevant one, to develop further. The thing that struck me was that the thin film aspect seems under utilized. If the efficiency needs it to have 31% larger areas, we should use it in areas where it can shine lige solar shingles or other applications, where lightweightness an thinnes are a real factor (maybe solar roofs in cars etc.)

[@johan-wh5qt]

Sorry but this time I cannot agree to your opinion on cadmium telluride solar panels. It's a little bit too positive. We have massiv global production capacities for silicon based solar panels and because of this they are very cheap. Additionally, the efficiency is today also at around 25 percent. All in all, silicon is easier, more common and better for recycling.

I have seen thin solar panels glued directly to adventure van hoods. I wonder if this is the type of solar technology being used on those recreational vehicles?

Especially when states like California are banning inexpensive, reliable fuels like propane.

I would have loved some kind of cost comparison between these technologies, since that is a key factor in adoption. I understand that price comparisons are difficult and that they should be taken with a grain of salt but it’s an important metric in the viability of a technology.

[@chimerawizard5639]

I would expect CdTe to be more popular for homes. 30 years retaining 89% of its effectiveness is nothing to sneeze at. That means it's a once per lifetime purchase. If they designed the panels around it, you could replace your whole roof in panels with fakes where gaps are required. Efficiency isn't that important as seen by Tesla's solar roof tile program. Longevity is. Cost is also important. The panels better be cost competitive with silicon otherwise the lower efficiency leading to more panels will become a factor in the initial investment.

I've been on the edge regarding getting solar panels. The main reason I might get them is there's a chance Trump will end the tax credits.

Is it worth spending $20k to save $100/mo? It's a 6% ROI, assuming everything works fine. I can get 5% putting the money in a CD.

[@tristanjones7735]

Honestly, I think the answer is to get the price as low as possible and worry about efficiency later. This is a classic mistake the green people make. Stop worrying about trying to get everyone off fossil fuels. That should have never been a goal and ironically, it is the very reason why transitioning away from fossil fuels has taken so long. Instead, focus on economic benefit. If you try to build a highly efficient off grid system, the payback period will be several years. However, if you build a small cheap system that is only designed to offset the need for power during the hours of the day that energy prices are most expensive, the payoff period might be as little as 1 year. Make alternative energy so cheap that the average homeowner can't afford not to do it. Don't regulate, don't subsidize it, don't give tax breaks. Just use good old fashion engineering to bring the cost down and worry about the last 5% of performance later.
