LARGE-SCALE SOLAR DOMESTIC HOT WATER SYSTEMS IN NORTHWEST EUROPE

Objective

- Cost reduction of SDHW systems by realisation of large-scale projects for various countries.
- Integration of SDHW systems in project development, architectural design, the building process, the conventional installation of large scale housing developments. Special attention for the implementation of quality control schemes already developed and architectural integration.
- International knowledge transfer and exchange regarding the above aspects.
- Realisation of over 3000 SDHW systems in 6 EU-countries by realisation of large-scale SDHW projects (100 to 1000 systems each in Denmark, Sweden, Germany, and The Netherlands and realisation of medium-scale SDHW projects 'approx. 100 systems each) in Belgium an the United Kingdom.
- Promotion of intra-community trade via public Call for tenders.

INNOVATION :
- The procedure of realisation of large-scale SDHW projects.
- The promotion of intra-community trade via a public Call for tenders.
CONTEXT :
Solar Domestic Hot Water (SDHW) is becoming a mature technology. In the past 20 years, R&D has led to significant improvements in cost-effectiveness of standard systems for family households. For a large-scale market introduction, a further cost-reduction is necessary, accompanied by rigorous quality control.
Two tracks should be followed at the same time:
- continuing R&D leading to lower manufacturing cost.
- large-scale project development, reducing selling and installation cost. This can reduce system cost by as much as 40%.
Favourable experience with the latter approach has been gained in an ongoing Thermie-project in The Netherlands (SE/479/92/NL), also known as the Apeldoorn Solar Project. In this project, now halfway, 1000 SDHW systems are being installed in a new housing development.
ECONOMIC ASPECTS :
The average payback time of the systems will be 12 years, where the life time of the installations is estimated to be 20 years.
