IEA Task 54 Price reduction of solar thermal systems

The aim is to reduce the price of solar heating systems. The price reduction shall be achieved by use of simplified system designs, cost-efficient materials, standardized and prefabricated easy to install components and reduced maintenance and operation costs.

The project is the Danish part of the International Energy Agency SHC Programme Task 54 project Price reduction of solar thermal systems for 2016-2017. The work includes participation in:

Subtask A: Market success factors and cost analyses

Subtask B: System design, installation, operation and maintenance

Subtask C: Cost-efficient materials, production processes and components

Subtask D: Information, dissemination and stakeholder involvement

Expert meetings will be attended. Knowledge from the international partners will be transferred to the Danish solar industry.

The Danish activities will be focused on both solar domestic hot water systems and on solar combi systems. Special focus will be on:

- Low flow drain back solar heating systems with a minimum number of components

- Hot water stores consisting of pressureless plastic tanks with built in standard hot water tanks

- Design of hot water stores with inlets making good thermal stratification in the tanks possible due to low velocity of the incoming water
