Minus the facts ... He has a wild misunderstanding of how solar cells work, how they fail, or how they dissipate heat. His thermal fails show signs of resulting from cracked crystals which frequently happens during the shipping and handling. The sandwhiching layers are NOT, in fact, insulators. The thermal performance with one thin layer of plastic is very close to that of the glass (an actual insulator) on one side and air cooled aluminum on the other. Failures frequently occur when people paste them to metal roofs that get hot in the sun. They are less efficient, they are not as durable, but literally nothing this guy says is anything but counter-hype. He is enthusiastic and convincing, just not accurate. Solar power is suffering terribly from over hype and the resultant backlash like this video.

Agreed! Some of what Will says doesn't seem to apply to them (like one cell damaged pulling down the panel). Also, Hobotechs experience doesn't seem to align with much of this and I haven't personally read of anyone else making these kinds of claims against Bouge/cigs flexible panels - quite the contrary.

I have glass panels in all my permanent installs, but I bought a semi-flexible one to use as a temporary vehicle battery charger when my car is parked for long periods. A glass panel would take up more space when not in use and also be more likely to damage the dashboard or trim due to the weight and sharp corners. So far the flexible panel is working fine. I'm reasonably gentle with it and it is entirely exposed on the back for heat dissipation as it is held onto the windshield with suction cups.

South-east England and I have just fitted a flexible panel, and the purchase was mostly based on the pop-top roof of our elderly camper. When we upgrade the camper, or the struts that hold that pop top! The mounted area is almost completely flat, so it shouldn't flex. It's a mono 150W etfe panel. It was cheap, fills a gap for us and can be replaced in a few years if the van is still with us. Nice work Will, love the videos, keep it up!

Dude your opinion is by far the best, I have ever seen. That’s saying a lot because, I have been selling and installing renewable, sense the early eighties. When I started, we made our own panels, I broke many cells while soldering the cells, to make a panel, not to mention the water proofing the panel. it’s so much better and easier today. Even after all of these years, I still feel that, a Home built, Axle Flux Wind Turbines is far better then, any manufactured wind turbine, on the market. NOW FOR ME, and for what I’m doing, I’m trying something very difficult, installing a panel on my boat. I would like to be sure my boat battery stays charged, I have a 20’ Thompson speed boat, that we use for fishing. While under power, I’m never worried about our charging abilities. There are those days, that we stay put all day fishing, our electronics, are always on. We have Humminbird Fish Finder/Deep finder, a Ship to Shore Radio, and other electronics. That’s a heavy drain of power, we start our boat every 1/2 hour or so, to keep the batteries charged. We added a extra battery in Parallel for extra capacity. My fear is if someone would ever forget to start the boat, they would drain out. I even keep a third battery on my boat on standby, just in case. Yes I’m paranoid, I would like to have a 200w solar panel charging them. I have always known for about the shittyness of flexible panels. Is there Something that you can suggest for my situation or is flexible my only answer, with the problems you have, rightfully explained. The next problem is the whole 12v thing, I hate them, I always considered them a waste of money. All of my off grid installations we use 36v panels. With Midnight Solar, Classic Charge controllers. I’m just in one of those weird situations, that I may need a flexible 12v panel, with some stupid and cheaply built controller. You would know this, what would be a decent small controller, that you would you suggest? I have never built such a small array before? Sorry for the novel dude. Your opinion is very valuable to me. I always send any new off grid costumer, of mine to you. They can get a education from someone, I consider one of the best that I have ever seen. You will go a long way in life, and will lead people to a much better future.

I appreciated the honesty at the end, we know you've bought a ton of equipment and you're being honest in your advice on what you spent on them and the disappointment. I've got two solar arrays and I'm looking for something to charge up a portable LifePO4 power station with. I was thinking flexible panels but now I'm thinking of just making a mounting system for a few glass panels.

@Yupp21 5 жыл бұрын

I agree that the inability to dissipate heat would cause failure of the panels or at least reduce its performance. Ambient temperature does account for a large portion of heat, but what is being show at 0:46 is from circulating current due to individual receiving different amounts of radiation, thus different currents. It has more to do with internal interactions rather than environmental temperatures. Also, this is an issue flat panels share, so his statements aren't technically true. It just happens more often with flexible panels because how they are being used.

@squireson 3 жыл бұрын

Unfortunately there has been a rush of super cheap prices advertised on flexible solar panels. The crystals in both the cheap and expensive ones are all the same at point of manufacture. The *mishandling* of the panels before point of sale is the major cause of these problems. Small cracks in individual crystals turn the the crystal into a resistive heater (it's not the sun melting them but the neighboring crystals pushing amperage through them, worsening the problem). You get what you pay for and the cheap rush is going to ruin solar's reputation before long.

@Sethjxl 3 жыл бұрын

I watched your video last year and decided I'd take the risk and go flexible as I needed to keep weight down. 12 months later, my output is down 40%, a glass panel of the same weight would provide better performance... Do it right or do it twice!

@MsSomeonenew 5 жыл бұрын

The hot spot issue is not due to materials used, thin plastic sheet performs the same as a thick slab of glass. The most likely culprit is in fact bending damage, these panels are handled 100x over and very likely to get small unnoticeable cracks which will keep getting worse once the material heat cycles, and once you have significant damage the cell no longer produces a comparable voltage to other cells so it becomes a power drain instead, now effectively working as a resistive heater. It could also be bonding issues, but that is again a very small change in heat dissipation.

@squireson 3 жыл бұрын

Yeah, he has misidentified the 'hot spot' cause. The encapsulation materials on glass panels are also insulators (-ish). While I deeply wish this weren't true, getting small orders shipped all the way from China/Indonesia means they get handled *alot* .

One of those last pics you showed of two flex panels on a fabric covering on a boat seems like possibly the best application for these panels. Tons of air flow! This is my first time looking into them. I'm interested in them because of their low profile because anyone with an eye for van dwellers can see that I've got ridged panels on the roof of my box truck. I mounted mine about an inch up because I was aware of the issues around panels getting hot. It always sorta confounded me as to how flex panels don't get hot, but I always assumed they just costed more because they didn't have that issue. I'm glad I say your video before I bought.

Wow! You just busted my bubble! I was just about ready to install my solar setup and just received my Renogy flexible solar panels. I enjoy watching your videos because I've always deemed you as the solar sun king! lol Your very knowledgeable and have always steered me in the right direction, however after watching this particular video I was bummed out cause I already purchased the flex panels. I suppose I could return them as I have not installed them yet and still have the shipping boxes. The premise behind me using flexible solar is because I am soon to be a Van Stealth dweller. If you put framed, glass type panels on top of a van and also add a max air or fantastic fan ventilation system on top as well, then you just lost your stealth mode. Flex panels are more stealthier, and I had planned on putting mounts and side ladders to help mask the vent cowling a bit. I suppose if I elevate the ladders a bit more it could help mask the other style of panels if I choose to return the flex and go with the other type. hmmm what to do? Back to the drawing board!

@InnovativeSustainableSolutions 5 жыл бұрын

Maybe just buy 1 flexible panel, rig it in parallel with the others and test for voltage/wattage output drop over time. Will has helped me out a lot with advice for my solar system; BUT in this video he talks a lot about, essentially cheap Chinese crap. And not a lot (any that I recall) about quality American owned and manufactured product like Renogy. I'm hearing a lot of anecdotal stories about people who have had their flexible panels for 5 years and are still working at 97% +, so maybe the jury is still out on the high end ones.
