The first panel that arrived was hit and cracked in shipping. After talking to company I should be getting my refund just wanting for my refund. I order a second one it arrived in great shape ready to mount. I was told the panel still works NOT.

These panels were overpriced as for the panels performance they are considered good to today’s standards, in peak or direct sunlight you can expect close to 300w for first year or 2 . All panels degrade and never reach there rated output. Panels work as they should if possible try self pickup because delivery cost as much as the panel.

Seems like a good product, use it to keep a friends 2000 Chevy van battery topped off, so it doesn't run down in weeks between use. Would like to see more consumer info on how heavy duty a solar charger you need for your usage - wondering if this one was over-kill - also, did find myself wondering why solar chargers will not charge a battery that is dead, slowly charge it over time -

Cable quality is good. The XT60 connector is well terminated, however there must be something I am missing as the solar connectors are either incorrectly marked or incorrectly wired. The + terminal is connected to the black cable and the - terminal is connected to the red cable. I’m planning on using this wire for another project right now, but this mislabeling is concerning because reversing polarity could severely damage any electronics it is hooked up to.
