I'm curious why anyone would install a solar panel for anything? Put in an
aux battery, and run the engine for 15 minutes or so every day, which will
produce about as much juice as a panel would all day (here's where David
jumps in with some hard figures).
Maybe if you weren't going to drive the van for a few months, it would be OK
for keeping the batteries up. Can anyone enlighten me?
