@squireson 2 года назад

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.

@AlanMcYou 9 месяцев назад

Perhaps you could redo this video with the newer CIGS panels?

@ScottDLR 2 месяца назад

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.

@whateverthisis3929 4 года назад

Will, the world needs you bro. This video saved me a world of hurt. My instincts on these panels were vindicated. Thank you a million times.

@billmaghan 3 года назад

I'm happy with my semi-flexiblepanel after four years. I mounted it on a thin sheet of masonite. Light weight and shock resistance are essential to me. I keep it indoors when not charging. I never expose it to the night sky because freezing might harm it. Mine is the one shown in your video.

@tonylatham5915 7 месяцев назад

Will: I think you need to update this. My Renogy flexible doesn't get any hotter than dark paint but my glass panel gets a lot hotter. Most are junk but there are several good ones now.

@stevep8773 3 года назад

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.

@anywhereroam9698 3 года назад

I think the flexible panels your are talking about are the flexible crystalline ones. There is also thin film (aka amorphous), which are meant to work better in low light and shade. You made a lot of good points.

@Yupp21 5 лет назад

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.

@d.wayneotto1094 6 лет назад

Awesome information and advice. Thanks Will!

@MsSomeonenew 5 лет назад

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 2 года назад

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* .

@michaelblock4397 3 года назад

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.

Thank you for this information, I was pretty close to pulling the trigger on a kit I saw on eBay for $300 CAD a few days ago.

@fairmania 2 года назад

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!

@4helex 5 лет назад

what about a layer of Corroplast or corrugated polycarbonate greenhouse covering sandwiched between the flexible panel and the vehicle for airflow/cooling? I was thinking of trying this but haven't seen anybody else try this. I know the ETFE coated panels last longer before clouding up.

Great review I agree with everything you said as everybody around me at the marina has flexible solar panels and I’ve never seen any last more than two years without falling apart except for a mate that has a pair of solbian panels , they are now 8 years old and the 100 watt panel is still putting out it’s 5 amps , the reason not every body has a good quality panel is because one of these panels costs 1300 Australian dollars

@squireson 2 года назад

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.

@drewjones1356 4 года назад

I've had flexible panels on my boat for 6 years and have noticed for at least the last three at least that the output has reduced dramatically. I was getting up to 25A from 360W but now only using 180W (2x90W panels) and getting 2.5-3.5A. A useful trickle but not much more... I will be going for solid panels when the time comes 👍

@ahaveland 6 лет назад

Fortunately with Sunpower cells, even cracked cells don't produce significantly less output, as long as the copper traces on the back remain intact. They still collect electrons from the silicon and perform as normal.

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.

Incompetent installation and/or *very* poor quality panels encounter these heat problems. The encapsulations on glass solar panels are also insulators. I , personally am a big fan of the aluminum backed semi-flexible marine solar panels as you can dissipate heat beneath them (if you can manage an air gap without getting flex form the wind)

@andy347 4 года назад

Agreed - I put some on my boat in Florida (on top of the bimini). Neither one lasted more than a year. They were fried by the sun. If they were smart they'd use flexible aluminum backing.
