What if l use two solar panels (20 watt 5-12 volts each one) both of them conected to a dual usb input to charge a phone or for example? Would i hace positive results?
Excellent, informative; to the point. I haven't properly addressed the heat dissipation factor while considering a solar panel design. Ty
Just run coolant under your sheet metal roof right?
Appreciate the info. I’m actually planning to have it for my semi truck.
Thanks for the heads up. looks like the rigid 120w solar panel is staying put!
renoygy states they can bend 248 degrees.. how far have them come since this video over a year ago?
Great video. Very useful information. What are your thoughts of the Sun Soaker 10W flexible solar panel for backpacking, etc?
Excellent videoclip!!! Thanks for all this super helpful info. I was about to place an order surrendering to an uninformed temptation,….
when you can get a 200w flexi for less than $70, which is less than 5 times the cost for heavy rigid panels, the light, slim, cheap flex panels are excellent as portable extra panels you can tuck away and only bring out when you are parked in the shade. So they may not last as long (duh, most cheap alternatives don't, but just do the maths). I have two large (250w) flexi panels as extras, I backed with a semi rigid plastic billbord material and cable-tied slim alloy channel around the edges, fitted longer cables and now I have 2 light, slim, cheap semi rigid panels that I bring out occasionally when needed. Sometimes it pays to go cheap, especially when there is no realistic expensive alternative.
Solution = Form fit copper plate, water channeled. You can fabricate a sheet that's fairly thin and has water channels running to a rad and small DC pump. Problem solved.
I found this video the day my flexible solar panel arrived..damn it. But at least now I will rethink installation and maybe store it on a shelf in the car, then i can use it purely when i need to top off a flattened battery or something, I will get a decent panel for long term mounting, thanks!
Can you please review renergy 2nd generations flexible solar panels? I heard they did alot to improve these issues. Im jus afraid to try them out and all the videos on them are bias
Crap….there goes my plans….thanks for the wake up call…..back to regular glass solar panels.
I was just about to buy one thank you so much 🙏🏻
Mine failed in 4 months !!! Garbage!
Cost me $400 off amazon and I mounted them on the aluminum roof of my rv (figured it would be a good heat sink) but they failed in 4 months and seller sais he will not do anything about it 😡😡😡
Will, your video is spot on. I bought (4) Suaoki 100W 18V 12V Solar Panel Charger SunPower Cell Ultra Thin Flexible with MC4 Connector on Amazon 18 months ago and they ALL FAILED. I mounted them with brackets on top of my RV for air flow and still failed. A lot of $$$$$$ out the door! Too bad I did not run into your video sooner. I now have Renogy 100 Watt 12 Volt Monocrystalline Solar Panel (Compact Design) and they seem to be solid with a good warranty.
I have 2 Renergy 100 watt flexible portable panels that I built PVC pipe frames for them with legs to pivot & put them out in the sun, bring them in at night. After 6 months, still generating the same power when I bought them. Also, their on an open frame so the dissipate heat well. They should last much longer this way then roof mounting. I wouldnt do that at all.
How about Sun Power? They seem to be a better quality. ML Solar does not produce they’re own solar cells. There’s a good chance that the solar cells are from China.
Righteous! The future's so bright, my solar panels came with a fire extinguisher!
Well back to the drawing board for my curved roof.
This may well be one of the most helpful videos on all of youtube.
I see a lot of van builds and other camper videos where people bought these and regret it. They were excited a year or two ago and now their panels are junk.
I want to ask, i plan to use flexible because it is lightweight. If I will use it on straight roof then I don't need to flex it, what I mean is it will neglect the disadvantage. Then why do I need a heatsink if the roof itself is a conductor? Or example on top of car, will it not dissipate heat in the form of the roof? What I mean is most probably you will install it on steady base which are metal.
I bought 2 x 100w of the ones you showed the advert for. They lasted 2.5 years before dying and replacing them with a 310w solid panel doubled my power output.
