How many solar panels do I need for my campervan?

Hi there!

I’m based in Cape Town, South Africa, and would like to take my campervan off-grid. How would I determine how many solar panels I need for this? Also, would you recommend monocrystalline or polychrystalline solar panels?

PS: I’m driving a VW Syncro :wink:

First of all, that is one cool campervan!

My brother in law had one back in the days…Unfortunately, it is sold now!

If you are based in sunny South Africa I rate you could get away with around 2 - 400 watt solar panels!

And monocrystalline, is definitely the better choice - it is much more efficient.


That is a really cool VW!

I have currently got X2 - 100 watt solar panels on my slightly more modern VW :wink:

That is a pretty cool setup!

SUP is covering the panel just a tad though :wink: Curious on the efficiency losses there.
