I have a couple of solar panels leading to a battery and the wires are your standard red/black type which I feel need some added protection from the elements. How can I protect them without cutting them or taking the croc clips off? They are currently laid between concrete slabs in the back garden (the gap between slabs is a good 5-10mm wide, handy!). Is there any clever sleeving out there for the job?
Cheers
Matt
