There are two variations of these heaters, roof-mounted and another is split. The panel is installed on the roof while the tank is on the ground.
Evacuated tube collectors: These operate like flat plat collector hot water heating systems functions. In this model, you can collect the sunlight through a series of glass tubes that contains a vacuum seal. This allows for the efficient transfer of solar energy. This makes the evacuated tube collector very effective yet expensive.
Heat Pump Systems: The heat pump solar systems draw solar heaters from the air and use the same to heat water. They use electricity to pump in hot air but negligible amounts.
