Solar water heating is generally more cost effective than an electrical water heater. Though solar water heaters usually have a higher initial investment if commercially purchased.
Solar heaters are useful for heating water with natural energy, thus saving electricity. The question is can effective solar heaters be made for less cost than using the electricity.
Solar and tankless
Solar panels and heaters are used. They trap sun's energy.
Strictly, solar panels refer to photovoltaic (PV) panels, that turn sunlight into electricity. Heating water is a different system. Water is pumped to your roof where it lies exposed in some way to the sun, heating up. If the water in your ground level tank is colder than the water on the roof, the tiny pump keeps running, and your tank fills with hot water. There are many slightly different systems, but the principle is the same.
Solar energy can be used as a power source for transportation. Solar energy can also power houses and other things.

Sun heating water, normally for domestic use,
Solar heaters are useful for heating water with natural energy, thus saving electricity. The question is can effective solar heaters be made for less cost than using the electricity.
You can, alternatively, you can place the water tanks on your roof for a somewhat naturally heated source of water.
Direct heating of solar-designed homes, solar water-heating, and electricalenergy from solar 'photovoltaic' cells, is all directly from the sun.
Solar energy is a form of renewable energy that comes from the sun's rays. It can be converted into electricity using solar panels or used for heating purposes like water heating or space heating.
Uneven solar heating
Solar collectors are components of a solar thermal system that absorb sunlight to generate heat. They are typically used to heat water or air for various applications such as space heating, water heating, or electricity generation through concentrated solar power systems.
Passive solar heating systems harness solar energy through the design and orientation of a building's windows, walls, and materials to maximize heat absorption. Active solar heating systems use solar collectors, such as solar panels or thermal collectors, to capture solar radiation and convert it into heat for space heating or hot water.
The plans for several types of solar water heating systems, It calculates what you are spending on heating water as a function of water .Only mystery is how did he bond the copper pipes to the corrugated metal absorber?
This all depends on what part of the US you live in. In the Southwest you shouldn't have a problem as sunlight is abundant. However, in places like Washington, you would need to buy a much more expensive style in order for it to work. They can be great, but it all depends on loaction and size of your house.
A parabolic mirror would be used for the solar heating of water. This type of mirror is designed to focus sunlight onto a specific point, creating high temperatures suitable for heating water or other fluids.
Solar power can be used for providing Electricity and heating and for hot water in the house
