2.6.1 Installation of solar thermal panels

Description

A solar thermal energy system is a technology that harnesses solar radiation to produce thermal energy, which can be used later on as DHW, heating or for swimming pool heating, among others. Additionally, by means of a trigeneration system, it can be even used for cooling.

Benefits

  • These systems can generate up to 70% of the energy needed in most residential and commercial establishments to power up the central water heating system. This means that renewable power is always available which can greatly reduce the need of fuel or gas and can help reduce electricity and/or gas (or other fuel) bills
  • It is a green-energy source, as it does not emit carbon dioxide to the environment
  • The installation is simple as it can be easily integrated to the existing heating systems

Limitations

  • This type of system is less effective in winter and an additional auxiliary device should be installed, like boiler or immersion-heater, to ensure that the heating system will still work during the winter months
  • The best performance occurs during summer months where there is not much need of a heating system

Economic assessment

Initial investment: High/middle cost (400-600 €/m2). An upfront investment to purchase the equipment and pay the installation is required to setup the system.
Payback estimated: 5-8 years, depending on the system configuration, subsidies, energy source replaced and others.
