According prognosis of future development of power capacities in Slovakia till 2030 there is assumed increasing of the electricalenergy volume, produced from renewable energy sources from present 260 MW approximately to 2100 MW (Petrovič, 2008), thatpresents almost 800 % increasing! In Slovakia position of photovoltaic in this sector was due to the high investment cost and on the lastplace due to the low system efficiency. Only possible way for implementation of the photovoltaic to the energetic system of the stateis 0donation. Slovakia will go this way also.
