Water and Solar window panels

[colshandy]

I havent used mine yet, is it advisable to fill it before leaving, or I guess a better way of asking is, is it okay to drive with the bottle full.

Also looking at minimising what I take. Are solar panels essential ? When are they best used ?

I know these are randon questions

Cheers
