I've a few questions about using this net fencing on sheep, I have read that many of you like it a lot. Some of you seem to have different opinions on whether you need to mow under the fence or not? Anyway, my dumb questions Is solar or battery better to charge? AC is not an option at this time. The joules, what is enough to keep sheep in and dogs out? For the battery powered ones, the batteries are rechargeable, yes? Are there battery powered ones that recharge with a solar panel? Looking on their site it appears so, but I don't really know the difference between a solar charger and a solar rechargeable battery one How much will one battery keep charged and for how long?
