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.
For example, if the open circuit voltage of your solar panel is 20V and the battery to be charged is rated at 12V, and if you connect the two directly would cause the panel voltage to drop to the battery voltage, which would make things too inefficient.
A 6V solar panel charger is a circuit designed to optimally charge a 12V lead-acid battery using a 6V solar panel. It provides approximately the same current as if the solar panel were directly connected to the battery.
The ADC output is multiplied four times and displayed on the LCD as battery voltage. When the solar panel voltage is present, the dusk-to-dawn sensor provides a signal to the microcontroller, which then displays 'charging' message on the LCD. During charging, the battery voltage is continuously monitored.
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.
This must be precisely set such that the emitter produces not more than 1.8V with a DC input of above 3V. The DC input source is a solar panel which may be capable of producing an excess of 3V during optimal sunlight, and allow the charger to charge the battery with a maximum of 1.8V output.
