Enertis Applus+ Study Reveals LONGi BC Modules Surpass TOPCon in Energy Yield and Cost Efficiency

Enertis Applus+ Study Highlights Superiority of LONGi BC Modules

A comprehensive study conducted by the global engineering consulting firm Enertis Applus+ has showcased the superior performance of LONGi’s Hi-MO 9 back-contact (BC) solar modules when compared to tunnel oxide passivated contact (TOPCon) technologies in a 47-MW photovoltaic (PV) project situated in Seville, Spain. This analysis, which focused on one-axis tracking systems, provides critical insights into energy yield and overall project profitability.

Key Findings of the Study

The research highlighted several key aspects regarding the efficacy of LONGi's technology. Notably:
1. Enhanced Energy Yield: The Hi-MO 9 modules boasted a remarkable achievement of 2,209 operational hours in their first year, resulting in a 3.4% higher energy output per watt compared to comparable TOPCon modules. This marked improvement directly correlates with increased revenue generation for solar projects.
2. Cost Efficiency: Despite having a premium price point, the additional cost of Hi-MO 9 modules (only $0.007/W higher than TOPCon) does not significantly impact total investment due to optimized system design and cost structures. This opens up a competitive landscape where their overall return on investment remains favorable.
3. Lower Levelized Cost of Electricity (LCOE): The LONGi BC modules achieved an LCOE of €0.02706/kWh—about 3.92% to 4.47% lower than TOPCon alternatives. This cost advantage results from reduced fixed and variable costs derived from higher energy outputs and improved compatibility with tracking systems, leading to lower electrical losses.

These findings not only validate the technological advancements of the BC modules but also emphasize their unique capacity to maximize lifecycle outcomes through efficiency gains and cost control.

Implications for the Solar Market

The results of this study carry significant implications for the solar energy sector. By showing that LONGi’s Hi-MO 9 BC modules can lower electricity generation costs dramatically, the technology positions itself as a strong competitor in the global energy market. This advantage is essential for companies striving to meet decarbonization targets while ensuring cost-effectiveness in renewable energy projects.

As the industry evolves, the clear performance edge demonstrated by LONGi could serve as a catalyst for broader adoption of innovative solar technologies. Leveraging such efficiencies not only aids investors and project developers but also aligns with global goals for energy sustainability and ecological responsibility.

In summary, the report by Enertis Applus+ provides solid technical validation for the deployment of LONGi's Hi-MO 9 modules in solar power plants worldwide. It underscores the company’s commitment to enhancing energy efficiency and supporting a transition towards a greener future.
