Extending cable for garden solar lights
I have a question re Extending the cable for my garden solar lights
I have a set of fusion rock lights as shown on
I need to place the solar panel in the direct sunlight so therefore need to extend the cables going to the lights ( which house the rechargeable batteries) I want to extend one cable by approc 5m and the other by 10m the third will be ok I wondered if I will get significant losses by extending the cables Vs the gain from having the solar panel in direct light instead of constantly in the shade ( not very bright when these ones come on ) perhaps if I use heavier cable to extend this may help.

The solar panel is described as 1.8W mono crystal the batteries ar 3* 1.2V nimh AA 150mah per unit supplies 3* LED cable supplied is 4.8m for each of the three lights
Hope this enough info If the cable lengths I want are too long maybe a suggestion could be made as to the maximum I should use.

Best regards

There should be no problem in extending the cables as the current/resistence (IR drop) is so small that it will easily be overcome with the higher voltage from the direct sunlight. I recommend replacing the entire cable with a good outside low-voltage cable as splices always seem to have problems being exposed to weather.

Re solar light cable extending
I will not be able to extend the complete cable as the rock lights appear to be sealed units !!!!! so can`t get access to termination...I assume I should use same grade cable as fitted....

If you can't get into the units due to being sealed, then the option is to splice the extention into the existing wire.
