Status of Solar Heating/Cooling and Solar Buildings - 2012

Status of the Market for Solar Thermal Systems

Market Size and Trends

The market for large solar systems for district heating has been growing the last
5 years - and this growth is expected to continue.

The market for individual systems has been stable on a low level approx. 10 MW/year the last 5 years - at the moment (October 2012) a tendency to a decreasing market is seen for individual systems.

Typical Applications and Products

The typical applications are:

  • district heating (3 000 - 35 000 m²)
  • domestic hot water in one family houses (3 - 6 m²)
  • domestic hot water in institutions (20 - 2 000 m²)

Main Market Drivers

For the large systems for district heating the main market drivers are the heat price and its stability. 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 year people seem much more interested in PV systems.

Industry

Main manufacturers:

  • ARCON Solar: Large collector modules (low export)
  • BATEC: Collectors and collector coating (low export)
  • SUNARC: Anti reflective glass coating (mostly export)
  • SUNMARK: Large collector modules (production not in DK) (some export)
  • VELUX:Collectors  (production not in DK) (mostly export)

Employment

Danish Solar Heating Association estimates the employment related to the production and installation of solar heating systems in 2011 to approx. 500 full time jobs. [Fakta om Solvarme, faktablad G07].

Costs

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

Support Framework

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

  • Financial support schemes: None
  • (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 the certification scheme for solar thermal installers: KSO (www.kso-ordning.dk) - voluntary scheme
    2. Products can be listed on a “positive list” operated by DSF, Dansk Solvarme Forening: www.god-solvarme.dk;  installers who are KSO certified shall use products from this list
