Development of support for ST in Germany
Beginning of
the 90‘s: some
of the German
states provide
grants for solar
thermal
systems
Problems:
Limited budgets,
different criteria
for allocation of
grants
1995: Market
intentive
programme
commences and
covers 30-40 % of
investment cost
Limits:
Budgets:ca.
30 Mio € for 4
years
1999: Budget
increased to 60
Mio € per annum
2001: Great
demand,
reduction of
grants to cover
only 10-15 % of
invenstment cost
2002: Market
crashes down
40%
2006: Boom in
demand, due
to high oil and
gas prices.
Budget ca.120
Mio €/a,.
Grants further
reduced
2007: Market
crash
Since mid 2007:
Increased support
for systems
2009: building
obligations
introduced and
budget increase
2010: support is
stopped, market
crashes
2011 /2012:
increase of
support per m²
Current support policies in Germany
Existing buildings (Market Incentive Programme MAP)
 Only support of combined DHW + heating systems with 90 € / m²
minimum of 1500 € / solar key mark approved collectors
 For extenisions of existing ST systems 45 € / m²
 DHW systems are only supported in big building > 3 or more
appartments & commercial buildings > 300 m² heated space
 Boni for change of heating systems, very efficient pumps, very well
insulated houses, connection to district heating systems
 Support for process heat + solar cooling systems of SME of
up to 50 % of investment costs
New Buildings: Renewable Heat Obligation (EEWärmeG)
New buildings must comply with very well insulation or use a renewable
heat source (e.G. solar thermal, heat pump, pellets, etc.) to cover
parts of the energy use

The Six Strategic Focal Topics
1. Full focus on the expansion of the established segments in the area
segment single-family and two-family houses
2. Development of further market segments by acquiring additional
competence (multi family houses, solar homes, etc.)
3. Committed entry to the solar heat future market of industrial process
heat up to 100°C (better understanding of market)
4. Consolidation of competitive capability through cost-efficient system
solutions and active development of the structural change (simple
systems / specialisation)
5. Prioritisation of research for development of cost-efficient solutions
in the established segments and industrial process heat
6. Active communicative organisation of general conditions required
for the increase in solar heat (end consumer communication)
The 11 market segments have different strategic meanings

Conclusions
 German solar thermal companies can look back
on a long experience in solar thermal technology
development and applications
 So far the main market is the residential sector,
but many promising market segments are to
become economically interesting.
 Precondition is further political willingness to
support the technology as well as improvements
in the technology, esp. to enable quicker / easier
installation.
 In the Solar Thermal Roadmap 2030 (2012), the
industry has formulated realistic potentials and
has started to work on realizing those goals in
Germany.
Thank you very much for your attention!
