Solar hot water systems have been gaining popularity as the world continues to move in a greener direction, with more eco-friendly energy ideas gaining momentum and becoming more commonly used. Using solar energy to heat up water is not necessarily a new concept, but the process has certainly been refined greatly, and there are many different potential applications as well as benefits to using this kind of technology.
The way this kind of solar system works is that you have a collector to gather sunlight and heat. The heat is transferred, typically through piping and via a fluid, towards a tank of water to be heated. Before this happens, you might find advanced systems that focus the sunlight onto the tube for heating. There are also two different broad categories of solar hot water systems, direct and passive, depending on how the heat and fluids are transferred and moved abut.
Many individuals hear the term solar and immediately think of electricity. However, a hot water system like this never directly produces electricity. The energy from the sun is instead directly used for heat. However, one of the popular applications for solar hot water is then to use that to make the electricity. These systems can be very large in scale and are effective, however there are still some concerns about the efficiency of these two piece process.
There are industrial, commercial and residential applications for using solar energy to heat up water. Residentially, this kind of system is often used to heat up pools, or used to regulate the temperature in an air conditioning and heating system. As mentioned, the process can be used industrially to produce electricity, and it can be applied in many different ways for businesses of various kinds.
The benefits to using solar hot water systems like this for hot water is that you are taking a big step towards reducing your impact on the environment and the footprint that you leave behind. Particularly with a passive system, you can entirely forgo the use of electricity to heat up water, which means you are less reliant on the grid, and are contributing far less in terms of pollution and worldwide energy usage.
Plus, although you have to pay for an initial system and the installation of that, over time you will actually be saving money. Hot water accounts for up to 25% of residential heating bills for many homeowners, and being able to cut into that by delivering some hot water via a system like this can add up to big savings over the years.
Hopefully by now you have a bit of a better idea about solar water systems and what they are all about. They are used to directly capture sunlight and heat from the sun, and use it to heat up water for various residential or industrial applications. While no electricity is produced, the process can be the first piece of a system that is used to produce solar electricity. Using a system like this within a home is a great way to cut back on environmental impact and lower energy bills.
