We have recently bought our Autocruise Stargazer and were lucky enough to have a satellite dish and Sky box included. Also included is a solar panel but we're not sure what its putting into the battery as there wasn't any paperwork to cover it. It is doing something as the basic monitor inside is lighting up indicating something is going in. We are, of course, thinking of buying a TV but are concerned that the power required will drain the leisure battery very quickly - we don't intend to use camp sites very often and therefore will not have hook-up. Is there any way we can improve the 12v supply?
