Solar water heaters are electrical devices that help heat water for both domestic and commercial usage. In contrast to traditional warmers, solar water heaters run on solar power. The solar thermal energy that is harvested from the sun is used to heat water as it flows through a solar water heater.

Growth Factors

The global solar water heater market size will be driven by rising demand for eco-friendly, dependable, and affordable technology for water heating solutions across residential and non-residential sectors. In comparison to traditional heating systems, the solar water heater has the capacity to provide low operating costs, or 25% to 40% in winter and 75% in summer. The demand for energy-efficient solutions is being driven by a growing understanding of how to use sustainable technologies effectively and rising infrastructure expenditure. The implementation of incentives like tax breaks, subsidies, and tax credits will also help to promote the use of sustainable technology, which will improve the outlook for the company. The need for energy-efficient water heaters is anticipated to expand every year as a result of the increasing depletion of non-renewable resources, together with greater efforts to control energy use. This should accelerate market growth during the timeframe of the projection. In order to appeal to a wider spectrum of clients, regardless of their financial status, these systems are priced inexpensively. It is anticipated that greater environmental awareness would spur industry expansion in both developed and emerging countries.

Market growth is anticipated to be fueled by rising demand for reliable, affordable, and environmentally friendly water heating technologies, notably in the residential and industrial sectors. It is anticipated that the system's capacity to operate at reduced costs—up to 75% cheaper in the summer and 30% to 40% lower in the winter—will encourage consumers to choose it over competing goods already on the market. For the installation of solar water heating systems, governments all over the world offer rebates and incentives. For instance, depending on the kind and size of the installed system, reimbursements of up to $700 are possible in Victoria, Australia's residential and commercial districts. On the other hand, solar water heating requires a large roof area and exposure to direct sunlight because it could not function on overcast or foggy days. However, improvements in backup energy systems that function even on cloudy days are anticipated to create profitable economic opportunities.

  • The global market for solar water heaters is expanding as a result of the solar water heater's energy efficiency and lower energy usage.
  • As fossil fuels are predicted to run out in the future, there is a growing demand for alternative energy sources for the electricity grid.
  • It's predicted that the market would expand as a consequence of sizable expenditures made by industry players in the solar water heater sector over the course of the forecasted period.
  • Growing need for cost-effective, dependable, and green water heating solutions, particularly in the residential and commercial sectors.

Key Market Drivers

  • The need for environmentally friendly and energy-efficient heating systems - The increasing demand for ecological and energy-efficient heating options is driving the global market for solar water heaters. Solar water heaters are reported to be significantly more energy-efficient than conventional water heaters. According to research by the IEA, the overheads of solar water heaters are anticipated to be between 25 and 50 percent cheaper than those of conventional water heaters (International Energy Agency). Due to their zero carbon emission rate, solar water heater demand is expected to rise in the approaching years. Solar water heaters are compelling the industry to replace conventional water heaters, in accordance with the "Kyoto Protocol," which was agreed upon by governments from all over the globe and limits carbon dioxide emissions out of each nation's industrial and commercial zones. Due to their energy and cost-effectiveness, solar water heaters are being adopted and utilized for household purposes in more residences.

Key Market Challenges

  • In less developed areas, there is less knowledge regarding solar water heaters - The failure to encourage and extend the use of renewable energy, particularly solar power systems, results in a lack of consumer understanding of its economical and environmental advantages. Given that solar power systems are a relatively new technology, consumers lack basic knowledge about them. For instance, given the short amount of daylight, some consumers may believe that renewable energy solutions are unstable. They might not be aware that intermittent technologies, when used in conjunction with other solutions like hybrid PV/thermal, are just as dependable as traditional ones. Additionally, public & private electricity suppliers might not be aware of the advantages that solar power technology systems can supply. Therefore, a significant market barrier is the lack of consumer comprehension of the advantages of embracing solar power.

Key Market Opportunities

  • Support offered by the government - The market expansion for solar water heaters is also being boosted by the assistance provided by international governments and governmental organizations. The government is required to encourage and promote less carbon emission systems and devices due to the carbon limit that has been assigned to each nation. The demand for solar water heaters for industrial applications is rising as a result of government policies and laws forcing businesses and manufacturing facilities to cut their carbon emissions. The government's funding of innovative projects and research into renewable energy sources is also boosting the market for solar-powered tools and appliances and boosting demand for solar water heaters.
