Agrivoltaic facilities, where solar panels are combined with agricultural activities, represent a groundbreaking approach to sustainable energy production. One key aspect of optimizing these facilities is the choice of whether to use single-axis trackers or fixed structures to mount the solar panels.

Agrivoltaic installations with single-axis trackers often have a lower Levelized Cost of Energy (LCOE) than those with fixed structures, according to recent studies and real-world experience. Here’s why.

Increased Solar Panel Efficiency

Single-axis trackers allow solar panels to follow the sun’s path throughout the day, ensuring that they consistently receive optimal sunlight exposure. This leads to a higher overall energy yield compared to fixed structures, where panels remain stationary. Greater efficiency means more electricity is generated for the same investment, which lowers the LCOE.

Extended Solar Panel Lifespan

By optimizing solar panel orientation, single-axis trackers can reduce the stress and wear on panels, potentially extending their operational lifespan. Agrivoltaic installations with longer-lasting panels have lower maintenance and replacement expenses over their lifespan, which lowers the lifecycle cost of electricity (LCOE)..

Maximized Land Utilization

Single-axis trackers can effectively utilize land that may have variable shading patterns due to nearby vegetation or structures. This efficient use of space ensures that more solar panels can be installed on the same amount of land, maximizing energy production without the need for additional land purchases or leases.

Reduced Energy Storage Needs

The improved energy yield from single-axis trackers can reduce the reliance on energy storage solutions, such as batteries, to maintain a steady energy supply. This reduction in energy storage requirements can significantly lower capital and operational expenses, thereby impacting the LCOE positively.

Adaptability to Seasonal Changes

Single-axis trackers can adapt to seasonal variations in the sun’s angle, optimizing energy generation throughout the year. In regions with distinct seasons, this adaptability can be particularly advantageous, further improving the economics of agrivoltaic facilities.

It’s crucial to remember that the decision between fixed structures and single-axis trackers can be influenced by a number of variables, such as the local climate, patterns of energy consumption, and the particular crops or agricultural operations being conducted beneath the solar panels. Even though single-axis trackers often have lower LCOE, permanent structures can make more sense because of their simplicity and cheaper initial costs.

In conclusion, improving energy output and economic feasibility through the use of single-axis trackers in agrivoltaic facilities is a potential strategy. The economics of agrivoltaics will probably get even better as technology develops and experience grows, helping to create a more robust and sustainable energy future.
