Hello everyone, I have a deep cycle battery that seems to provide all our lighting requirements. We use led globes sparingly. Just wondering whether a small 12 volt tv would drain the battery to much,or whether we would need to connect a solar panel to top up the battery and if so what size panels we would need. (100 120WATT??) obviously it would depend on usage.probably a couple of hrs a day at most. Thanks so much can anyone help?

A small LCD TV shouldn't draw more than a couple of amps, so depending on the size of your battery, shouldn't be a serious concern. It depends too on how you are charging the battery - if from the vehicle, and assuming that the battery is a decent size (say 50Ah or more), running the TV shouldn't cause any worries.
Solar? The TV will probably draw say 2 amps for 2 hours = 4 amphours. To replace that on a daily basis will take a few minutes if charged from the vehicle. A small solar panel, say 10W, will easily supply that in a day of sunshine. Before considering solar though suggest think through your whole system - do you want to charge torches, phones, laptop, etc, or maybe consider a fridge for the future? There is more to solar than simply clipping a panel onto your battery! And it can be expensive.
