Analysis of LONGi BC Modules vs. TOPCon

In a significant development in the solar energy sector, a comprehensive study conducted by the global engineering consultancy firm Enertis Applus+ has revealed compelling insights regarding the performance of LONGi's BC modules compared to TOPCon technology. This analysis, focused on a 47 MW photovoltaic project utilizing single-axis trackers in Seville, Spain, showcases the advantages of BC technology in terms of energy production, cost control, and overall commercial viability.

Key Findings

The analysis highlighted that

• - Power Generation Efficiency: The LONGi HPBC2.0 Hi-MO 9 modules displayed an impressive energy generation rate that exceeded their TOPCon counterparts by approximately 3.4%. Specifically, the Hi-MO 9 modules generated about 2209 operating hours in their first year—this performance resulted in increased project revenues, showcasing the effectiveness of BC technology in maximizing yield.

• - Cost Parity: Despite the pricing of the Hi-MO 9 modules being marginally higher by 0.7¢/W compared to TOPCon, the overall capital expenditures (CAPEX) remained competitive. This result was attributed to the meticulous design optimization of the system and significant cost reductions in various areas, which ensured that the financial viability was not compromised.

• - Industry-Leading LCOE Reduction: The study's results indicated that Hi-MO 9 modules achieved an unparalleled Levelized Cost of Electricity (LCOE) of 0.02706 €/kWh, which is 3.92-4.47% lower than the LCOE of TOPCon modules. The substantial cost advantages stem from a reduction in fixed costs per unit of energy produced due to heightened efficiency and enhanced compatibility with tracking systems, coupled with reduced electrical losses during generation.

Technical Validation

The findings from this analysis underscore the robust technical validation provided by the BC technology. By enhancing efficiency and controlling costs, the LONGi modules demonstrate a unique capability to optimize return on investment over time.

This efficiency improvement, combined with the ability to minimize electricity production costs, positions the Hi-MO 9 modules as formidable competitors in global energy markets. Moreover, these developments significantly contribute to broader sustainability efforts and decarbonization initiatives.

Conclusion

As the demand for renewable energy continues to grow, the implications of this study are profound. LONGi's BC modules not only promise enhanced returns on investment but also align with the global push toward environmentally friendly energy solutions. The findings advocate for the adoption of BC technology in utility-scale solar installations worldwide, solidifying its place as a critical component in the future energy landscape.

In conclusion, the study by Enertis Applus+ validates the potential of LONGi's BC technology to lead the way in solar energy efficiency and affordability, further enhancing its commercial value while supporting sustainability goals globally.
