seconding what the other commenter said: this is a fine tutorial showig how a 12v battery can be boosted, but that or any tiny solar panel is only going to generate 250 ma or so in full sunlight . If you're charging a smallish 12v battery that is 25 ah (=25000ma). Even assuming all of the charge was retained by the battery (usually you need to put an extra 10 -20% in) you're talking 100 hours in the sun. Yes it could trickle/keep topped up, which is a great use for it - but not a normal charge from 'used last week' to 'I want to use it next week'.
