At Horus Energy, the renewable energy division of Grupo Onyx and leader in solar photovoltaic electricity generation in Guatemala, efficiency does not stop at simply generating energy. We extend this principle to every aspect of our operations, especially in the maintenance of our facilities. During the dry season, one of our main maintenance activities is the cleaning of the 345,000 solar panels that make up our park in Chiquimulilla, Santa Rosa.
The Importance of Cleaning Solar Panels
The solar panels at Horus Energy are critical to producing enough clean, renewable energy to power approximately 60,000 homes in the region. However, to maintain this level of production, each panel must operate at its maximum capacity. This is where the importance of keeping the panels clean, free of dust, dirt, and other debris that can block sunlight and reduce energy efficiency.
Innovative Technology in Solar Cleaning
To meet this challenge, Horus Energy has adopted a cleaning methodology that not only preserves the efficiency of each panel, but also respects the environment. We use specialized rotating brushes that clean the panels efficiently, removing dirt without damaging the surface. This method not only ensures that the panels are treated with the care they require, but also optimizes the use of water, a critical resource, especially during the dry season.
Efficiency and Records in Maintenance
Our efficiency in this process is remarkable. With a dedicated team and the right technology, we have set a record in cleaning all of our 345,000 panels in just 13 business days. This achievement not only demonstrates our capability and commitment to operational efficiency, but also underlines our innovation in sustainable maintenance practices.
Innovative Methods for Cleaning Solar Panels: Global and Local Strategies
Around the world, different companies adopt a variety of cleaning strategies tailored to their geographic contexts and specific needs. We explore some of these innovative techniques that reflect the diversity and creativity in the solar industry.
- Automated Cleaning Systems: Cleaning robots and drones equipped with sprayers and brushes allow access to difficult areas and are especially popular in large solar plants.
- Cleaning with Deionized Water: It uses water that does not leave mineral residues, avoiding deposition that can affect the efficiency of the panels.
- Electrostatically Based Systems: In Japan, some systems use electrostatic fields to repel dust without the need for water, ideal for arid regions.
- Unmanned Ground Vehicles: Vehicles equipped with cleaning systems drive along rows of solar panels, covering large areas quickly.
Geographic Considerations in Panel Cleaning
The selection of a cleaning strategy also depends on geographic factors. For example, in desert regions, where dust and sand are prevalent, waterless systems are especially valuable. In cold climates, specialized snow and ice removal techniques are necessary to maintain panel operability.
Conclusion
At Horus Energy, we understand that efficiency in cleaning solar panels is as vital as the technology of the panels themselves. We adopt practices that not only keep our panels in top condition, but also respect the environment. Every day is an opportunity to innovate and improve, ensuring that our contribution to the country and the planet is both sustainable and meaningful. Thus, we not only generate energy, but we also create a positive impact on the community and the environment.
