Abstract
LEON-VARGAS, Fabián; GARCIA-JARAMILLO, Maira; MAGIN YARA, Gelver and PARRA, Alejandro. Effect of Soiling on the Performance of Photovoltaic Modules in Bogotá. ing. [online]. 2021, vol.26, n.2, pp.273-283. Epub Sep 19, 2021. ISSN 0121-750X. https://doi.org/10.14483/23448393.16601.
Context:
This study analyzes the soiling effect on the energy efficiency of two photovoltaic generation system configurations: one fixed and one mobile (with solar tracking).
Method:
A support system and output power measurement adapted for each configuration was implemented. Data was collected during two months in Bogotá. This analysis considered the average power obtained in two 50 W polycrystalline photovoltaic modules integrating each configuration. A test module was assigned for applying a cleaning protocol in each configuration, and the remaining module was assigned as a control module. This result was used in a pre-feasibility analysis for energy self-sufficiency of an average, middle-income household.
Results:
A regular cleaning protocol increases the energy productivity of each analyzed photovoltaic system in 3,87% and 7,23 %, according to its configuration. Additionally, at the economic level, this increase in productivity represents the year-prior amortization of a photovoltaic system for energy selfsufficiency, regardless of the type of configuration used.
Conclusions:
A positive impact on the energy efficiency of the two photovoltaic configurations analyzed was found under a regular cleaning protocol in Bogotá. This benefit increases the profitability that could be obtained from investing a system for the energy self-sufficiency of an average family.
