These are nice sized powerful solar panels. They are *really* hard to break and are ideal for charging batteries or other small projects. You could happily leave them outside
The panels are all physically the same size, same weight and produce the same power (4.5watts) They are just configured differently so that you can have a higher voltage, but lower current, or higher current and lower voltage.
