PL W pracy przedstawiono obecny stan rozwoju fotowoltaiki w Polsce. Instalacje fotowoltaiczne najczęściej z modułami monokrystalicznymi pracują w trybie zasilania awaryjnego lub jako podstawowe źródła zasilania odbiorników w energią elektryczną. Jednak najefektywniejsza jest praca tych instalacji w try[...]
EN The present development of photovoltaic in Poland is presented in the paper. The PV installations with monocrystalline modules are the emergency sources or they are the main sources of electricity for electrical devices. However, the most effectively exploitation of PV installations is when they are[...]
