As the world shifts towards renewable energy sources to combat climate change, solar power has emerged as a leading contender in the race for clean energy dominance. For utility-scale solar projects, one key metric stands out in determining their viability: the Levelized Cost of Energy (LCOE). LCOE reflects the lifetime cost of generating electricity from a solar installation, encompassing factors such as the initial investment, operational expenses, and energy output over time. In this article, we delve into the pivotal role that solar trackers play in reducing LCOE and enhancing the efficiency of utility-scale solar projects.
What Exactly Is LCOE?
LCOE is a metric used to assess the lifetime cost of generating electricity from a particular source, typically expressed in terms of dollars per megawatt-hour ($/MWh). It takes into account various factors such as initial investment, operational and maintenance costs, fuel costs (if applicable), and the expected lifetime of the project. Lowering the LCOE is a key objective for renewable energy projects, as it enhances competitiveness with traditional fossil fuel-based sources.The Role of Solar Trackers
Solar trackers are devices that orient solar panels to maximize exposure to sunlight throughout the day by tracking the sun’s path. Unlike fixed-tilt systems, which remain stationary, solar trackers dynamically adjust the angle and orientation of solar panels, optimizing energy capture. This ability to continuously optimize solar panel positioning yields several advantages that directly contribute to reducing the LCOE of utility-scale solar projects.Increased Energy Yield
By tracking the sun’s trajectory, solar trackers can capture more sunlight throughout the day compared to fixed-tilt systems. This results in a higher energy yield per installed capacity, effectively increasing the electricity output of the solar installation without requiring additional panels. Single-axis trackers, in particular, offer significant yield enhancements of up to 35%. While double-axis trackers boast the highest yield increases, single-axis trackers strike a balance between performance, initial investment and maintenance costs, making them an optimal choice for utility-scale projects.Mitigating Weather Risks and Enhancing Durability
Solar trackers equipped with advanced weather monitoring systems and intelligent stow protocols offer additional benefits beyond yield optimization. They can mitigate weather-related risks by automatically stowing panels during extreme conditions such as high winds, flooding, or snowfall. The Nevados All Terrain TrackerⓇ (ATTⓇ), for instance, incorporates features like wind dampers integrated into the bearing to withstand hurricane-force winds of over 90 miles per hour. Moreover, its resilience against differential settlement events ensures long-term durability and reliability, further reducing operational risks.Eliminating Grading Costs
Traditional solar installations often require extensive grading of the terrain, resulting in substantial upfront expenses. However, true terrain-following trackers like the Nevados ATTⓇ offer a game-changing solution by eliminating the need for grading altogether. The ATTⓇ is designed to adapt to diverse terrains, accommodating significant post-to-post angle changes of up to 26%. By bypassing the need for costly grading processes, projects utilizing the ATTⓇ can significantly enhance their cost-effectiveness and overall LCOE.Leveraging Tax Incentives for Added Savings
In addition to operational efficiencies, solar trackers can also amplify cost savings through favorable tax incentives. Recent guidelines under section 45X of the Inflation Reduction Act provide bonus tax credits for trackers meeting domestic content requirements. By leveraging these incentives, solar projects can reduce upfront expenses and enhance financial returns. At Nevados Solar, we offer a robust domestic supply chain to help developers meet these requirements and maximize their projects’ economic viability.Harness Solar Trackers for Optimal Economic and Environmental Impact
