This contribution is oriented to measurement and evaluation of the
obtained energy from photovoltaic cells efficiency in practice conditions. Photovoltaic
cells were monitored during one year in Nitra, Slovakia. Cells are monocrystalline with
surface 1.95 m2 and in full measurement time are directed perpendicular to the sun rays.
Tracking and stationary systems were used for results evaluation. Six cells per system
are used in the combined serial-parallel connection. Output energy from both systems is
496.257 kWh. Price of obtained energy is 69.48 EUR for actual price of electric energy,
which is 0.14 EUR per kWh. The output power of the photovoltaic tracking system was
higher by 20.39% opposite to stationary system. Ovaj rad se bavi merenjem i ocenom efikasnosti dobijene energije iz
fotonaponskih ćelija u praktičnim uslovima. Fotonaponske ćelije su bile praćene tokom
jedne godine u Nitri, Slovačka. Ćelije su monokristalne, površine 1.95 m2 i tokom punog
merenja usmerene upravno na sunčeve zrake. Za ocenu rezultata su korišćeni praćenje i
stacionarni sistemi. Šest ćelija po sistemu su upotrebljene u kombinovanoj serijskoparalelnoj
vezi. Izlazna energija iz oba sistema je 496.257 kWh. Cena dobijene energije
iznosi 69.48 EUR po trenutnoj ceni električne energije, što je 0.14 EUR za 1kWh.
Izlazna snaga fotonaponskog sistema praćenja bio je viši za 20.39% u poređenju sa
stacionarnim sistemom.
