My solar lights are SMD DS.
Somebody copied two models of our lights, rolled the mechanicals and
body moldings together into a hybrid, reduced the cost of some parts,
did some mechanical 'improvement' (while missing some crucial points),
copied part of the electronics and produced a simplified subset
version. SMD board except for a 1 Watt through hole resistor mounted
on copper side. All the rest SMD but wholly single sided.

Photos of their PCB sometime maybe. SMD + SS.

PCB. One of ours DS - mainly SMD - cost aspects result in some TH.
Mainly Al ecaps and inductor here.
