Reviews

  1. S. Sprague (verified owner)

    I purchased a flexible 50watt solar panel and controller, which I installed on the roof of my campervan. It works great, my leisure battery is always topped up, allowing me to recharge phones, laptop, AA batteries, camera, run van lighting etc, even while parked-up several days, as at festivals. Tony was very helpful when I ordered the kit, I called him a few times to ask advice on installation as well as choosing what to order. In all a 100% satisfactory experience. Thank you
