I buy items in the U.S. And have them received at a UPS store or other small company just across the border. They hold them until I drive down to pick them up, I clear them through customs
myself. I don't know if you could save enough to go through the hassle. I saved $350 on 4 tires last year.
I keep a boat in Florida
, last year I bought a 325W Kyocera
panel from eMarine for around $400 U.S. It is mounted above our bimini
aft of the boom. We have no back stay so virtually no shadows. I'm using a Rogue MPPT
controller. I'm very pleased with the performance. I think one large panel is more efficient. The controller only needs to deal with one panel, the voltage is higher, current
lower. And only two connections on the one panel.
We run a fridge, freezer
, LED lights
. The one panel usually supplies all our power when we live aboard.
I have pictures of the install in an album on my profile here on this site.
