Hello Alsion, Thank you for your feedback, you can keep the light in the sunny position and in the switched OFF position for 3 to 5 days to get the best charge the panel will still gather a charge into the battery in the switched off position, this way the lights will gather a booster charge. and aftewr the 5days switch them on in the evening and they will work perfectly
Hello,
There is no extension cable for this or a way to make it longer. Sorry!
