Where is a 12 kWp photovoltaic array located?
The system has been analyzed in Baghdad, the capital of Iraq, using experimental meteorological data. The 12 kWp photovoltaic array is positioned at the optimal annual tilt angle for the selected site. The temperature effect on photovoltaic modules is taken into consideration.
What is the energy management technique for a photovoltaic system?
Hassani et al. [ 30] presented an energy management technique for a photovoltaic system with battery storage and an electrolyzer for hydrogen production, where each subsystem was developed to determine the most appropriate quantity of hydrogen-supplying components. An energy management system was implemented to control these various sources.
What are the components of a photovoltaic system?
The system consists of five primary parts. The first component is the PV array responsible for power generation; the next is AC/DC converter, an electrolyzer, a compressor, and a hydrogen tank. The photovoltaic array with the converter is responsible for controlling the amount of DC power that is transported to the electrolyzer.
How many modules are in a photovoltaic array?
The photovoltaic array consisted of 12 modules with a total power of 12 kW p (module specifications presented in Table 1 ). The array was installed and placed at the optimal annual orientation for the chosen location. (tilt angle = 30° and azimuth angle = 0° south facing).
How much energy does a photovoltaic system produce?
It has been found that the annual energy generated by the analyzed photovoltaic system is 18,892 kWh at 4313 operating hours, and the obtained hydrogen production cost ranges from USD 5.39/kg to USD 3.23/kg. The optimal electrolyzer capacity matches a 12 kW p PV system equal to 8 kW, producing 37.5 kg/year/kW p of hydrogen for USD 3.23/kg. 1.
