Automatic solar powered LED light can be used for Garden, outdoor, farm etc… this circuit constructed with 6V solar panel and 12 high bright white LEDs. You can use 6V/4Ah SLA battery this will get charged during day time though the solar panel power and during night time this battery acts as power source for LEDs.
The LDR placed in this circuit drives LED as off during day time and on during night time with the help of SL100 switching transistor.
