Simple solar charger circuits are small devices which allow you to charge a battery quickly and cheaply, through solar panels. A simple solar charger circuit must have 3 basic features built-in: It should be low cost. Layman friendly, and easy to build. Must be efficient enough to satisfy the fundamental battery charging needs.
Place the solar panel in sunlight. Check the battery voltage using digital multi meter. Circuit is simple and inexpensive. Circuit uses commonly available components. Zero battery discharge when no sunlight on the solar panel. This circuit is used to charge Lead-Acid or Ni-Cd batteries using solar energy.
Here is the simple circuit to charge 12V, 1.3Ah rechargeable Lead-acid battery from the solar panel. This solar charger has current and voltage regulation and also has over voltage cut off facilities. This circuit may also be used to charge any battery at constant voltage because output voltage is adjustable.
Solar battery charger operated on the principle that the charge control circuit will produce the constant voltage. The charging current passes to LM317 voltage regulator through the diode D1. The output voltage and current are regulated by adjusting the adjust pin of LM317 voltage regulator. Battery is charged using the same current.
To be able to control the voltage from the solar panel usually a voltage regulator circuit is employed relating to the solar panel output and the battery input. This circuit ensures that the voltage from the solar panel by no means surpasses the safe value needed by the battery for charging.
For instance, if the open circuit voltage of your solar panel is 20V and the battery to be charged is rated at 12V, and if you hook up the two instantly could cause the panel voltage to decrease to the battery voltage, which might create things too ineffective.
