Status of Solar Heating/Cooling and Solar Buildings - 2019

Status of the Market for Solar Thermal Systems

Market Size and Trends

The market for solar district heating (SDH) has been growing very fast in the decade up to 2016.

In 2016 more than 500,000 m² (350 MW) was installed for SDH.

In 2017 the SDH market dropped to below 20 MW - mainly due to the end of an approximately 10% subisidy scheme at the end of 2016.

In 2018 the SDH market was up to 40 MW - and perspectives for 2019 are good (> 100 MW).

The market for individual systems has been on a low level approx. 5 - 10 MW/year the last 10 years - with a tendency to a decreasing market.

Typical Applications and Products

The typical applications are:

  • district heating (5 000 - 150 000 m²)

Main Market Drivers

For the large systems for district heating the main market drivers are the relatively low and stable solar heat price. Heat from large solar fields is competitive with heat price of gas and some kinds of biomass.

The small systems are not as competitive as the large systems - and during the last years people seem much more interested in PV systems.


Main manufacturers:

  • ARCON/SUNMARK Solar: Large collector modules and systems for district heating and industrial applications (low export)
  • Aalborg CSP: Large CSP modules and systems for disrict heating, industrial applications and electricity production (some export)
  • SolarVenti: Airheating collectors / systems


The estimated employment related to the production and installation of solar heating systems in the record year 2016 is approximately 1,300 full time jobs. [according to calculation method given in Fakta om Solvarme, faktablad G07].

On average it would be 500 - 600.


Costs of large systems for district heating:
Collector field installed including piping in the field, heat exchangers, pumps, control, etc. 225 €/m² excluding VAT

Costs of individual systems:
Small domestic hot water system for individual houses, 4 m² collector:  3,500 € including 25% VAT. The price is the additional price to install a solar water heater instead of a conventional water heater. [Fakta om Solvarme, faktablad G09a].

Medium size hot water system for (e.g., institutions) 100 m² collector:  42,000 € (420 €/m²) excluding VAT. The price is the additional price to install a solar water heater instead of a conventional water heater. [Fakta om Solvarme, faktablad G09a].

Actual Innovations

The innovative trend right now in Denmark is solar district heating systems (up to 150,000 m²) with seasonal storage (up to 200,000 m3) - and in some cases combined with large heat pumps.

Support Framework


Danish Climate and Energy Policy:

The long-term goal for Danish energy policy is clear: the entire energy supply – electricity, heating, industry and transport – is to be covered by renewable energy by 2050.


Government Agencies Responsible for Solar Thermal, for Solar Building Activities

Danish Energy Agency:

Most Important Public Support Measure(s) for Solar Thermal and for Solar Buildings

  • Financial support schemes: Minor support to energy savings (incl. solar) in district heating
  • (Building) regulation: Solar thermal counts in the calculation of the energy performance of new buildings and major renovations; these have to fulfil strict requirements for energy use
  • RD&D Funding: EUDP
  • Quality control:
    1. Installers can join voluntary certification schemes for solar thermal installers: KSO ( and VE Godkendelsesordningen (
    2. Most large systems are sold with a guarantied power performance

Information Resources

National Solar Associations (industry and non-industry)

At the moment there is no national solar thermal association in Denmark.
