Not quite as bad as I made it sound, as such systems are usually plumbed into your normal (electrically-heated) hot water system, so the water that is solar-heated would go in to your immersion heater and stay warm.
As long as the solar-heated water is hotter than that already in your tank, it will keep cycling it to keep it hot. At night, it will stay hot for quite some time, but your electric element may come on if it cools too much.
So a solar-water-heating system is an addition to, not a replacement for, your normal system and, together, they will give you hot water 24 hours a day using less electricity.
I don't have any personal experience of who to use in TV :-(
