seas SEAS-PhotovoltaicOntology ontology 2016-01-01 2016-05-26 The Seas PhotovoltaicOntology Ontology for the ITEA SEAS (Smart Energy Aware Systems) project. v0.9 Takoua Ghariani Batteries used for grid-storage also stabilize the electrical grid by leveling out peak loads, Converts the direct current (DC) from the solar modules to alternating current (AC) A solar tracking system tilts a solar panel throughout the day DischargeEfficiency DischargeRate ChargeCost ChargeRate MaximumStorageLevel LowerStateOfCharge ChargeEfficiency InitialStorageLevel is a potential induced performance degradation in crystalline photovoltaic modules, caused by so-called stray currents. This effect may cause power loss of up to 30 percent Solar cell efficiency is the ratio of the electrical output of a solar cell to the incident energy in the form of sunlight
