Solar thermal energy in Slovakia


Mandatory targets set by the Proposal for a Directive of the European Parliament and the Council on the promotion of the use of energy from renewable sources from January 2008 indicates 14% share of RES on the final consumption of energy. In 2007 the Slovak government prepared "Strategy for the Comprehensive Use of Alternative Energy Sources", which sets the target of 6% RES in primary energy consumption and the "Draft Strategy for Security of Energy of the Slovak Republic". The Strategy sets following targets for heat production: 2010: 27 000 TJ of heat should be produced from renewable sources; 2015: 43 000 TJ of heat should be produced from renewable sources.

Renewable heat: solar thermal

The Slovak government has published its intention of assisting private households to use solar energy and biomass, it is planned to assist the installation of solar collectors under certain conditions with approx. Sk75 million annually. According to Slovak Energy Policy this document, it is necessary to support utilization of solar energy (and biomass) through subsidies for solar systems and biomass boilers for flats and family houses. Starting from January 2008 a subsidy of 3 000 (98 EUR) SKK for 1 m2 of collector surface and 24 000 SKK (788 EUR)  together with 1 500 (49 EUR) SKK for 1 m2 (if more than 8 m2) was introduced. Current price of the most common 6 m2 solar system for preparation of hot water in family houses is approx. 100 000 SKK (3 283 EUR)  including installation, it means that costs with 19% VAT could be covered by the subsidy.

Possible financing sources for solar thermal technology in Slovakia:

Up to 90% for public sector; private sector - up to 50%




In April 2007, the Slovak Government approved a framework of support for increased household use of solar energy, financed from the State budget. This framework will be developed in more detail in the Programme for increased household use of biomass and solar energy, which the Slovak Ministry of Economic Affairs approved in September 2007. Grants are awarded subject to certain criteria being met. The overall amount of funding earmarked per year will be SKK 100 million (about EUR 3.2 million).

Technology                                    Support level [%/total investment] Start year                                           End year

Solar Thermal      collectors            cca 20%                                                                                       Theoretically 2009                            2015

Future programme changes expected

Exploitable potential of solar energy for heat production is approx. 34 000 TJ and the objective of utilization according the Energy Policy Paper is 300 TJ in 2010 and 3 000 TJ in 2020. Yearly operating solar system under Slovak climate conditions can cover up to 60-75% of hot water needs. There is considerable room for expansion of the use of solar energy and this is intended to be achieved, inter alia, by financial support for private households. In the coming years, solar energy, in particular in the generation of heat and hot water as well as refrigeration, will be increasingly used.
