Flexible Solar Cells E60 C60 5x5 3.6W Monocrystalline Cells for DIY Panels (20, +2 Busbars Per Cell)

I would not be surprised if these are second or third efficiency bin, but they arrived undamaged and pass muster as far as open circuit voltage and short circuit current for my purposes are concerned. I recommend NOT using a soldering iron and instead using an 18650 spot welder (backed up with a 12V 100 Ah LiFePo battery) at low power (weld energy 5) for fast, clean, easy and reliable results.

I bought 120 even though I only needed 80. I still ended up running out. A large number of cells were outputting at less than 70% of spec, and of those, half were below 30%. Cells are also very fragile and prone to breaking during soldering and assembly.

I’m extremely happy with these and I will absolutely buy more in the future! These are exactly as described! Thanks! 10/10!

Came alot sooner than expected! Great condition, I havent built my solar unit yet but if it works I will be getting more!
