The project is part of the IEA Solar Heating & Cooling (SHC) Task 69 on ‘Solar Hot Water for 2030’. The aim of the project is to identify which hot water technologies are the most appropriate and have the biggest potential in the view of the 2030 targets regarding the solar hot water industry. The project will define the market status (current standards and new SHW technologies), core technical issues for development, and the trainings/standards needs for cost-effective and reliable solar water heater technologies.

There will be a focus on the development path and best practices for two technologies which are expected to play the biggest role in the solar hot water market in 2030: solar thermal thermosyphon and solar photovoltaic (PV) derived hot water heating systems.

International collaborations among participants from the different IEA SHC member country regions will take place in order to consider differences in economic development, solar resources, regulations and other factors. An important part of the project is to analyse how to overcome barriers to further deployment in different climates and markets of solar thermal technologies. Moreover, opportunities to improve the performance, cost, and reliability of solar water heaters will be identify and considered.

If the project is implemented successfully, it will encourage the utilization of solar photovoltaic (PV) and other solar heating technologies for building heating purposes. As a result, there will be a reduction in the consumption of natural gas and oil, and the energy system will become more resilient and adaptable.
