The black bear population is on the increase in my area, so I am considering a fence on at least one of my yards.
There is no source of electricity at that yard, so I will have to use a solar charger. Anyone have a unit that they would recommend?
I have heard that at least one joule is require, but the ads seem to specify a number of miles range rather than joules of output. When joules are listed, it is generally less than one in the solar units. Is there a correlation between joules and miles of range?
