What Is Solar Water Heater?

Understanding solar water heaters is fairly simple.  Solar water heaters use the solar energy from the sun to generate heat (not electricity) which can then be used to heat water for showering, space heating, industrial processes or even solar cooling.  Our planet's primary source of energy is solar energy, and it is responsible for providing the energy which goes into plant growth, which eventually makes our planet habitable. The deives that use solar energy to heat water have been for around 100 years, but the last 20 years have defined the true purpose of a solar heater. Advances in absorber coating technologies, resulting in solar collectors that can reliably convert >50% of available sunlight for domestic hot water supply. The thing that brings most of the customers to the land of solar water heaters is the fact that it can reduce energy cost by a huge amount, and end up leading to high financial savings.

The way a solar water heater works is that the collector captures and train heat from the sun, and transfer this heat into the liquid. Solar thermal heat is trapped using the “greenhouse effect,” in this case is the ability of a reflective surface to transmit short wave radiation and reflect long wave radiation. Heat and infrared radiation (IR) are produced when short wave radiation light hits a collector’s absorber, which is then trapped inside the collector. Fluid, usually water, in contact with the absorber collects the trapped heat to transfer it to storage.

Simplest way to explain a solar water heater would be a hot water heating system that runs on solar energy. The system is developed with numerous solar panels that are connected together, so as to harness the energy of sun. This energy is then further used to heat the water. Most of the time, solar water heaters are not able to run by themselves due to the fact that solar energy is not constant. There are times when the output of the solar panels is not enough to heat the water, and this is when the electric energy kicks in to finish the job. But solar water heaters do save customers a huge amount on energy bills. The only complication would be that installing and maintaining the solar panels turns out to be a lot of hassle for people who would not have time for it.
