How Solar Water Heater Save Money and Energy Consumption?

Posted on Mar 13, 2021

Water heating for domestic usages plays a very important role in domestic applications as a replacement for gas consumption and electric based water heating system for people to have warm water supply for various different purposes. This applications stem from solar power technology that converts energy from sunlight into other form of energy either directly such as photovoltaic or indirectly such as concentrated solar power. Some combined usages are also popular in the market.

Solar power and energy consumption

Speaking of solar power, this is the conversion of energy from sunlight into most electricity, by either directly using PV or indirectly using concentrated solar power, or even combination as the means. In practice, concentrated solar power systems utilize lenses or mirrors and solar tracking systems to focus a large area of sunlight into a small beam, which is why is called as concentrated solar power. In fact, photovoltaic were initially solely adopted as a source of electricity for small and medium-sized applications. Commercial and industrial concentrated solar power plants were first developed in the 1980s. Later, since the cost expense of solar electricity has fallen due to many issues, the number of grid-connected solar PV systems has grown into the millions and after that, many utility-scale photovoltaic power stations with hundreds of megawatts are built for people’s convenience as well as for the environment.

Classification of solar power

In the market today, many industrialized nations have installed significant solar power capacity into their grids as infrastructure in order to supplement or provide an alternative to conventional energy sources for ecological friendly issues. While on the other side, an increasing number of less developed countries have turned to solar to reduce dependence on expensive imported fuels from foreign countries which may help them gain more autonomous and be less susceptible to the foreign power. Moreover, long distance transmission permits remote renewable energy resources to displace fossil fuel usages.

In addition, solar power plants mainly utilize one of two technologies. The first one is photovoltaic systems which use solar panels, either on rooftops or in ground-mounted solar farms and convert sunlight directly into electric power form. On the other side, concentrated solar power plants adopt solar thermal energy to make steam, which is thereafter converted into electricity by a turbine measure. No matter which system is used, for domestic usage considerations, the main goal is to generate hot or warm water supply for users for their household purposes. Some Taiwanese people used to use the generated water for bathing purposes since most of the fuels in Taiwan depends on importation so that in the recent three decades, more and more people choose to install such facility to have autonomous of their energy option. However, this once for all installation doesn’t promise once for all heat, cause sometimes when the sunlight is not enough or maybe none, then alternative options are to be considered by those people for the urgent heat water usages. As a result, solar water heaters are not that invincible in industrial usages for users all over the world.
