The paper defines and describes factors that should be considered when hybrid energy supply systems that incorporate solar systems in particular are planned. In the first point; the author establishes the hierarchy of criteria to apply at subsequent phases of the decision processes carried out when renewable energy systems are to be used. To do this; the authors take the advantage of shortly described case studies: a solar hot water system in an elderly house and an integrated system of steam boilers together with heat recovery from a cooling system in connection with solar heating in a food production plant; etc. Then; the paper indicates the necessity of energy simulations prior to taking up the decisions of localization and to final verification of the project. The example of the simulation method called equivalent thermal network is mentioned in the comparison to the advantages and disadvantages of the other software described. Some forms of promotion are presented; which can be applied to positively stimulate the sustainable development of the use of renewable sources in the European central eastern region on the background of a short comparison.
