hey guys just messing around at home and deiced im going to build a solar trickle charger for 12v car batteries first off i was after a lil info on solar panels whats the best type??? second i was wondering if a 10w or 20w solar panel would be enough for this type of application??
I thought thats what the alternator was for... and if your battery is dead why would you only want to trickle charge it?
its not dead working fine same with the alternator just wanted a project![]()
