Solar garden lights circuit

The solar panel  provide 5.5 V and 150 mA. Assuming 3.7V/1500mAH battery charging is complete in 8 hours at 200% capacity at 180 mA. With 10 LED energy consumption would be 90 mA / hour provides a 10 hours lighting light levels 50 lumens to 60 lumens. LEDs 20 the light intensity will be from 100 to 120 lumens.

You can use any number of LEDs and battery capacity too. This will directly provide the amount of time for lighting and illumination. If you use a higher capacity battery than the current recommended solar panel should be increased proportionately. Current provided by the solar panel must be 10% of the battery capacity.
