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

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

 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.
