Removing reliance on non-renewable energy sources through solar water heaters is a promising and cost-effective approach to mitigate the impact of over-reliance on fossil fuels. The growing concern about global warming and scarcity of fossil fuels has directed the world towards sustainable technologies.

Solar water heaters, a type of solar energy system, use sunlight to heat water for various purposes including domestic use. This renewable energy is considered an attractive solution for global energy challenges as it requires minimal maintenance, can provide heated water during on-site generation, and can be easily scaled up or down in terms of performance.

A well-designed solar water heating system consists of a solar collector a storage tank a circulating pump and a storage tank. The key component is the key component of the system, absorbing and converting sunlight into thermal energy. The solar water heater works in two cycles: the thermal phase and the off-peak phase. During the heating phase, the solar collector heats the fluid in the circulating pump, and in the cooling cycle, the hot water is pumped into the commercial building for actual use. Conventional heat pump systems also improve efficiency by using a second heated fluid to heat the system whenever possible.

Implementing large-scale solar water heater systems can significantly reduce the electricity consumption. Data suggests that, for every 1.2 MW of solar water heater capacity installed, the demand for utility electricity from electricity suppliers is decreased by at least 1.2-1.5 MW.

In new economies, such renewable energy sources can save households a significant amount of money on their energy costs.

It is estimated that global implementation of solar water heaters could reduce energy usage by 8-15% by 2025, saving over $1.1 trillion in electricity costs.

With such impactful advantages associated with solar water heaters, governments worldwide should prioritize and invest heavily in developing solar water heater technologies, providing support for manufacturing and large-scale deployments.

However, current industries are lacking the competitive pace on solar thermal technologies, driven primarily by the development and promotion of solar photovoltaic (PV) technology. Regulators must therefore provide immediate attention and subsidies to renewable energy sectors, besides focusing on eliminating bureaucratic hurdles for business owners to step into the industrial energy markets.

Increasing the demand for solar water heaters will also heighten employment prospects worldwide, and reduce salaries in renewable energy industries while raising profit margin expectations among the companies in this area. So the deployment of solar water heater technologies will undoubtedly prove instrumental for saving energy requirements and making a significant difference in solving one of our most enduring environmental problems.
