I use the rough & ready 70% calculation to estimate a panel’s output when mounted flat or close to.
Wattage of panel divided by nominal voltage & multiplied by 70%.
In this instance 150/12 = 12.5 12.5 x70% = 8.75A ..... so I’d agree with MT’s estimate of 8.5amps.
However - brand new panels often perform over spec & ‘settle down to more conservative figures after a little regular use. In addition a bright but cool day, particularly if close to large bodies of water (reflection) can also push output above specs. These are the exception rather than the rule though. It is also possible that this new solar blanket has a higher efficiency that
most panels available, but I too wouldn’t expect that from SCA products.
So Lucas, when, a bit further down the track, your panel’s output is more like MT expected - don’t be disappointed - it’s normal.![]()

Measured with a clamp metre it wasn't quite 10amp some thing like 9.7 but close enough for me.
Even 8.5 amps I'd be stoked with. Fridge draws about 4 so even if it was running constantly id be in front
I do have another 120w foldable if i ever needed more juice
