What ever you do get a heavy duty operator, you will have alot less trouble with them. I also recommend you get an electric latch, takes alot of the wind load off the operator which can trip a limit switch. I have used some Mule operators with the solar panels, no problems with holding a charge but they seem to be only half way reliable. All the keypads, driveway sensors, solar panels and key fobs are bullet proof, the trouble is usually tripping a limit switch.
