They say that with no past exists no future and therefore the research activity, regarding the lifecycle management in implementation and maintenance of green energy infrastructures started by consulting literature and people dealing with green energy generation industry, finding out that the most “scientific” works are based on inherited slightly demonstrated customs and habits from other areas. Comparing the results from the developed researches with the others results it was confirmed that the most convenient form of green energy source in the area of Cluj County is the solar one. Within the data gathering process, it was no real “big surprise” to find out that like in football (soccer), or politics, where as many experts claiming that they know how to fix their favorite team, as if their opinion is grounded in proven fact), solar energy generation seems to be a subject where everybody is an expert. But, if in football we may not bother to argue against “experts claim”, since they are drunk on their stubborn outlook and will reject any counterargument, we may not have a similar reaction in the case of some strategic managers. Gained experience shows the good part, after a time when the local managers state the “evidence” that is no need to consultancy or other experts opinion because any expertise is futile for such a “simple” applications, they stuck or get in large investments problem. The stucking point is the start point for the change management, when the local managers came back, asking for real detailed solution with technical arguments, economic business plan and risk management. But as mentioned that is after a time when solutions, activities and solutions implementations must be rescheduled with just a fraction from the initial budget, or with a much larger one. In any case, concerning the implementation of solar electric generators, the most common first questions are: It is rely necessary this change? It is not better to go in the cozy old fashion way? Obviously there is no middle answer, people are strongly divided in extreme positions between an absolutely YES (being “convinced” that the solar solution is the most convenient one) and an absolutely NO (as an unreliable and expensive solution, not capable to cover the actual necessities and to constitute a viable alternative). As presenting a part of a larger study, the aim of this paper is to present how the change management is considered from the first steps in the implementation of a solar energy generator as a need in the complex change process from totally fossil to a hybrid system (that may reach 100% solar) in the presence of economic change triggering factors (CTF). The need of change management (CM) in the implementation of solar energy generation begins from the very moment and first discussion between the service provider (facilitator, consultant, research team, etc.) and the decisional factors (end-users). The change management process starts with the identification of the startup information flow between: the Endusers request (EUQ) and the Service provider offers (SPO). That implies that between the two partners is an optimization agreement (a compromise), the best results provided by the Service provider are possible only if the End-user will open the access to the internal (real, consistent and updated) information. As Kotter mention (Kotter, 2013), communication is crucial in building consensus and for that the End-user decisional level must be completely involved.
