This is flexible solar panel, but more reliable than regular flexible solar panel for the reasons below. 1 it uses Sunpower Maxeon gen 3 solar cells, which are 3.6W per cell at mppt voltage. More efficiency than traditionally used Sunpower C60 cells. And in general Sunpower cells are better than non sunpower solar cells, because even if they break, they still produce enough electric energy. 2 it uses custom junction box which is only 10mm thick and it's thinner than long slim junction box traditionally found.
3 I have room for improvement for more reliable way to solder solar cells together. 4 my design solar panels are always etfe nether pet technology.Check the photos provided to see the advantage. 5 my design solar panels are always fully transparent for more cool design and for easy way to find out why solar panel broke eventually. Unlike traditional non flexible, glass surface solar panels which tend to last and produce enough solar energy even after 20 years of usage, flexible solar panels normally only last 1-3years if they are Non ETFE or non Sunpower and 2-5 years if they are traditional ETFE with Sunpower cells. Obviously it depends on many various factors. Flexible solar panels don't last long mainly because the connections between cells get compromised.
Another reason is that traditional flexible solar panels are using PET substance for its front surface. Think of PET plastic as of higher than average quality transparent plastic sheet.And most plastic as you probably know with time yellow and degrade because of UV and other rays from the Sun. But from my experiments most flexible solar panels stop working because of compromised connections between cells. It's because ETFE(kind of mix of transparent plastic+ceramic+non stick pan surface substance), solar cells(kind of mix of ceramic+very fragile thin glass substance) and inter cell connections(kind of a mix of solder metal+copper)contract&expand at different rates when cold or hot. After some time those expansions and contractions make the inter cell connections break or become very highly resistive and that makes panel output much less power.
Traditional thick solar panels normally have different structure and way more reliable design. 6 I have some working prototypes how to attach such flexible solar panel to Any car or any van with special DIY magnets. There is nothing like this on the market.I will include the more photos eventually to demonstrate my designs and advantages. 7 this is just a preorder. I need people texting me with some feedbacks and more suggestions on flexible solar panels. So I would talk toy Chinese factories and keep on improving the design and reliability.
8 my solar panel has much higher mppt voltage than regular 100w flexible solar panel. Because most mppt controllers can easily handle 100-150v input voltage. And with traditional 1pcs of 100w flexible solar panel you can only charge 12v lead, lithium, lifepo4 battery.It's because 99% of mppt charge controllers are buck style, means step down. So in order to charge any battery, you need solar panel system's mppt voltage at least 2-5V higher than the voltage you want your battery to be charged. 10 left to answer your questions and requests...
