The Australian landscape of large-scale solar farm maintenance is rapidly evolving, and solar farm cleaning has become a critical component for maximizing efficiency and energy output. Initially, many manufacturers underestimated the importance of cleaning solar panels. However, the industry has since recognized the necessity of effective solar farm cleaning with appropriate and efficient solutions.
Without enhanced solar farm cleaning, energy production declines, leading to revenue losses for asset managers and owners. The efficiency loss due to soiling is estimated at 2-5% annually worldwide, resulting in over €4 billion in losses each year. In large-scale PV plants, even a 2% soiling loss can justify the need for thorough cleaning.
For large-scale solar farm cleaning, a diverse array of equipment is available, ranging from tractor systems to robots. Each type of equipment has its own advantages and disadvantages, depending on the size and layout of the solar farm. Often, a combination of various equipment types is necessary to achieve optimal cleaning results.
Due to the vast size of solar farms and the need for cleaning optimisation, farm tractors are commonly used. These tractors support hydraulic-driven articulated brushes, which are crucial for cleaning the wide strings of solar panels. The space between rows typically accommodates this type of machinery, ensuring thorough and efficient cleaning.
The articulated brush, attached to the tractor, is the most prevalent equipment used. It is often self-adjusting, employing capacitive or hydraulic sensors to maintain optimal cleaning pressure. The length of these brushes varies, ranging from 2 meters to as long as 8 meters, allowing for versatile cleaning solutions tailored to the specific needs of your solar farm.
By investing in the right combination of solar farm cleaning equipment, Solar Shine Australia ensures your solar panels are cleaned effectively, enhancing their efficiency and maximizing your energy production.
