I love my solar fencer, it seems to get plenty hot, but I did buy one that was a bit more pricy, has a large solar panel, will do miles of fencing and even on coudy days without much sun says it will stay charged up and ticking. I use the electric tape as back up for my wire mesh fence now so it is not flying solo, however, before I got my minis I used 2 inch wide tape with a solar fencer for two full sized horses. I had some posts driven in to the ground, especially on the corners of the field and I pulled the tape tight between the brackets attached to the posts. I used step on temporary posts between the driven posts to keep the tape supported. I also put in 3 strands of tape rather than just one so from a distance it looked somewhat solid. It worked ok for me, but I will say I do sleep better with the mesh and hot tape combination I have now.
