How to calculate the total time a battery can operate light?
hi,I am willing to just use solar panels to recharge my batteries and then to power my garden lights. What I need is how do I know if my battery will be able to power my lights for atleast 24 hours. How do I choose the solar panels to be able to charge the batteries. IF I know how to calculate for atleast one light and battery that should be enough for me to calculate for my whole system.
