Dataset for: Sizing and optimization of a stand-alone photovoltaic system for refrigeration – a case study in Tizi-Ouzou, Algeria

This dataset accompanies the article "Sizing and optimization of a stand-alone photovoltaic system for refrigeration: a case study in Tizi-Ouzou, Algeria".

It contains all files required to reproduce the analytical sizing and simulation validation presented in the paper.

CONTENTS:
- README.txt: Main instructions and citation information
- README_PVsyst.txt: PVsyst simulation parameters (export not available in demo mode)
- nasa_sse_tiziouzou_irradiation_data.csv: Monthly solar irradiation from NASA SSE (1990-2020, Table 1)
- refrigerator_duty_cycle_june_2025.csv: 1-minute duty cycle data (June, 30 days)
- homer_pro_tiziouzou_simulation_data.csv: Hourly HOMER Pro time-series (8760 hours)
- pvsyst_parameters.csv: PVsyst system parameters for manual setup

The optimal configuration obtained is 1.5 m² PV area and 34 Ah battery capacity. HOMER Pro and PVsyst validation shows <3% error.
