Algerian solar study shows impact of maintenance on plant yield

A six-year assessment of a solar facility in Algeria highlights how pandemic restrictions affected output.

Key points

  • Researchers analysed six years of operational data from a 12 MW solar plant in Sidi Bel-Abbes.
  • Performance dropped in 2020 due to reduced maintenance during COVID-19 restrictions.
  • The performance ratio recovered to 84.83% by 2023, according to pv magazine.

Researchers at Djillali Liabes University evaluated a 12 MW grid-connected solar installation in Sidi Bel-Abbes, Algeria, covering the years from 2018 to 2023, pv magazine reported. The study tracked operational metrics and meteorological data to understand long-term plant efficiency.

Maintenance and performance

The facility recorded a marked performance decline in 2020. pv magazine noted that researchers linked the drop to reduced cleaning and upkeep caused by COVID-19 restrictions. "This drop in yield underscores the crucial role of regular maintenance," the researchers stated. According to World Bank figures from 2021, renewable sources accounted for 0.9% of Algeria's electricity output, making the operational efficiency of existing infrastructure critical for the region.

Long-term recovery

Following the disruptions of 2020, the plant's performance ratio rebounded, reaching 84.83% by 2023. The six-year average performance ratio stood at 82.6%, demonstrating competitive long-term resilience despite temporary operational setbacks and highlighting the necessity of sustained cleaning protocols.

Context from CEII

Renewables are the fastest-growing part of the world’s energy system. The COP28 goal is to triple capacity by 2030, and solar mini-grids are the fastest route to power for millions of people without electricity.

0.9% of electricity in Algeria was renewable in 2021
