Monoaxial trackers, also known as single-axis trackers, are a device commonly employed in photovoltaic (PV) power plants. Unlike fixed-mount systems that keep solar panels stationary, monoaxial or single-axis trackers enable the panels to move along a single axis, tracking sunlight throughout the day. This dynamic orientation optimizes solar panel exposure to sunlight, leading to increased energy production and improved system performance.
What are the Advantages of Monoaxial Trackers?
Some of the advantages are listed below:
1. Increased Capacity Factor: Single-axis trackers substantially raise the capacity factor of solar power plants. The capacity factor represents the actual energy output relative to the maximum potential output. By tracking the sun’s movement, these trackers ensure the panels maintain an optimal position for maximum sunlight absorption. This results in a more consistent and predictable power output, leading to an increased capacity factor and improved financial returns.
2. Extended Daily Production Curve: In contrast to fixed-mount systems that have a limited peak energy production period around noon, monoaxial or single-axis trackers extend the daily production curve of solar power plants. Through continuous tracking, these trackers enable the panels to maximize energy production over an extended period throughout the day. This extended high production period aligns with the electricity demand curve, particularly during peak consumption hours, improving grid stability and reducing the need for additional energy storage.
3. Improved Morning and Evening Performance: Fixed-mount systems have limited sunlight exposure during the early morning and late afternoon due to the low solar elevation angle. In contrast, monoaxial trackers can tilt solar panels to effectively capture sunlight during these periods when the sun is closer to the horizon. This improved morning and evening performance led to increased energy production during valuable hours, resulting in higher overall energy generation.
4. Flexibility and Adaptability: Single-axis trackers exhibit high flexibility and adaptability to various terrains and geographical locations. They can be designed to withstand wind loads and adapt to local climate conditions. Additionally, their modular design allows for scalability, enabling PV power plant owners to expand their installations gradually without significant infrastructure modifications. The adaptability of monoaxial or single-axis trackers makes them suitable for a wide range of project sizes and locations.
In conclusion, monoaxial trackers offer significant advantages over fixed-mount systems. These advantages result in higher energy yields, improved financial returns, and enhanced grid stability. Consequently, these trackers are a compelling choice for maximizing the potential of solar power plants.
