Did a project using 8 of those small panels and found that even that many were not of any real use. You need a minimum of about 30 watts from a solar charger to do any recharging of the battery. If you are not using anything on that battery you will be recharged in about 24 hours. (if the sun was out for 24 hours). That means you really need about 90 watts output to charge a battery in one day. These panels are about 4 foot long and two foot high and run about 420 bucks a panel. Can be found at RV stores. •••••••••••••••••••••••••••••••••••••••• jimt Planned insanity is best.
