This　paper　is　based　and　written　on　performance　analysis　of　a　10kW　Grid　connected　solar　power　system　with　a　comparison　in　integration　of　bifacial　photovoltaic　systems　vs　mono-facial　photovoltaic　system.　Thus,　all　these　tastings　were　carried　out　on　computer　simulations　using　PVSyst6　software　MATLAB/Simulink.　These　simulations　were　done　considering　different　albedos　and　tilt　angles　in　order　to　identify　power　variations　under　different　environmental　conditions.　The　selected　panels　used　mono-crystalline　type-high　efficiency　cells,　both　in　bifacial　and　mono-facial,　and　therefore,　the　technical　parameters　of　both　cell　types　will　be　the　same　in　operating　conditions.　With　the　results　obtained,　it　has　shown　the　power　gain　in　ground　mounted-grid　connected　bifacial　solar　system　is　23%　more　than　mono-facial　solar　power　system,　and　using　these　details,　author　proposed　a　table　that　represents,　most　suitable　PV　panels　for　different　site　conditions.　©　2019　IEEE.
