Any solar water heater's engine is the solar collector. Solar vacuum tubes have traditionally been the most efficient solar power generation devices, but they have also been the most costly. However, the rising demand for solar energy, along with current manufacturing processes, has brought down the cost to the point where vacuum tube technology offers the highest return on investment when compared to any other solar collector system.
