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

Q: I'm thinking of putting 20 of these on my hood to keep my van battery topped off. Can anyone recommend a diode or charge controller for this?

These aren't as flexible as they advertise them as being and actually snap very easily. You might be better off buying a pre-built panel if you're trying to mount on your car.

Q: I built a 20 cell panel and get 13.2v in bright sun with almost 6a of output, but if i connect straight to a sla 12v, will these leak at night?

It's always better to use a charge controller between solar panels and a charger. Even during the day when you have a cloud or some shadow pass by, your volts can drop and battery current go back into the cells. Without a charge controller, you can use a diode to make sure current only flows in one direction. Search for solar diodes you'll find something cheap that'll do the trick for you.

Im new to solar panels. it say .6V per cell, how many cells are in each panel?

Easy to spot weld

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.

Extremely high defect rate. 1 in 4 performed poorly. Some DOA.

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.
