When I installed my Ghost Controls dual gate opener this summer, I used the two battery system with the 10w solar panel. I live in the Pacific NorthWest (Southwest Washington) and sunny days are few and far between from about November-February. When the weather turned, I noticed that the batteries were running down and the gate would stop working once or twice a week on approximately 5-10 gate cycles per day, so I'd have to disconnect the batteries and put them on the battery charger. That got old quickly, especially in cold and rainy weather. I purchased the 30w solar panel and added it to the system in parallel with the 10w panel. It's been up for about two weeks now and not a single gate failure. Installation was quick and easy and took about 30 minutes total. I secured a 3" diameter ABS pipe to my fence posts and mounted the panel to the pipe with the included clamps. Works like a charm!!

Why would you make the attachement so difficult to set? The screws are tiny and this the lip around the panel, its impossible de set it securely .

We didn't want to run electricity out to the gate. Perfect solution!
