solar blanket

My brother has the 120w and 200w Kings.

Yes they are excellent value, as good as Supercheap Australia (SCA) Ridge Ryder folding blankets when on special.

We found the Kings 120w was 1amp more output than my 100w SCA unit, the Ridge Ryder being slightly more output than spec, and the Kings slightly under their spec.

The Kings 200w didn’t work first time it was set up, the panel worked on other controllers, so took the Kings controller back and they found it was wired up wrong way on output.

Just an alternative to solar blankets. While they are a good thing and can be stored easily they have to be positioned on something etc.
Probably you have a roof rack and use it for carrying gear. A fixed panel can be added to the roof rack and used for charging vehicle or van with appropriate cables/plugs.
For $85 you can buy a 160 watt panel which in theory delivers around 9 amps and is 120cm x 54cm x 3cm. It can be used as a portable panel or fixed or even on a slide under the roofrack and slid out when stopped. It then offers some shade for the vehicle. Some use them and silastic them to the van roof too connected integrally or via an anderson plug fitted to it's edge. Yes a regulator is required for flat panels. It can be positioned close to the battery connection for best results.

I considered folding and flexible panels but the cost is far more than fixed and so have recently bought three of the above, 2 side by side for the vehicle, replacing two 80w panels of same area, and one for the van roof.
Your choice of course.

I have a kings 120 and it is fantastic. Laying flat on ground will regularly push out 6-8amps all day.
