4.2.2 Capacity configuration of PV-battery-electrolysis hybrid system. Taking into full account the operating conditions of each equipment in the PV-battery-electrolysis hybrid system, the lifetime of the system is assumed to be 20 years; considering the time value of money, the investment cost is amortized each year through an annualized factor.
The exploitation of solar energy and the universal interest in photovoltaic systems have increased nowadays due to galloping energy consumption and current geopolitical and economic issues.
The results of this work are similar to previous results involving PV-battery systems with high inverter loading ratios (ILRs), or ratios of DC PV capacity to AC inverter capacity: greater degrees of oversizing of the VRE generation increase a hybrid system''s capacity factor but not necessarily its capacity credit, especially as PV and wind generation shares …

It was shown that the annual energy production of the hybrid system exceeded the load by 160% and the hybrid system achieved consistent energy autonomy using a very small battery bank [112]. For more technical studies based on practical data, the performance of a PV-HES system in Antarctica was analyzed with two-year operation data.
For the calculations related to solar photovoltaic energy production, the following data are used [77]: nominal cell power of 320 W; efficiency of photovoltaic panels (η PV) of 19.6%; irradiation (kWh), which is equal to the calculation of irradiance (I m) times time (t), as shown in Table A1; area of photovoltaic panels (A) equal to 1.94 m 2; and temperature loss coefficient (θ …
The addition of electrical energy generated from Renewable Energy Sources (RES) in the energy infrastructure can create severe mismatching between supply and demand of electricity, which enforces operational and capacity limitations on RES-based systems [1, 2].A balance between energy supply and demand can be reached through effective energy storage …
