Measures for increasing demand of solar energy

Renewable energy sources (RES) will have to play the main role in moving towards sustainable economic development. Talking about the perspectives of the use of solar energy, it is evident that the main market is decided by the consumer. The most important problem, determining the slow absorption process of solar energy on the part of the consumer, is the lack of knowledge and organisation, deterrent amount of investments, and especially the differences between energy suppliers and users in the heating sector. The main focus of the research is what conditions are needed for heat energy that is produced by users on the basis of solar technology and how it would be able to compete with other energy sources. District heating (DH) may be appropriate infrastructure to implement RES technologies both on production and demand side due to the simultaneous production of heat and electricity in combined heat and power generation plants. Conclusions have been made concerning the scale and assumptions of how solar technologies may be competitive.
