Now I have four of them. Two 4x4s and two Honda jet skis are hooked up to batteries to keep them charged. If I buy batteries for about a hundred dollars each every year, I can now service the battery for at least four years (I don't know yet since my four-wheelers are still running). I used Lexel glue to glue them to the tin roof of the barn. I have a 50 foot cable connecting my quads and a 25 foot cable connecting my jet skis. There were no problems with this extra length of wire. I recommend one panel for each battery. I had a chance to speak to the company owner when he sent my last two panels. He's just a small businessman with a great product and does most of the work himself. I give this product and this business the highest recommendation.
