At present, photovoltaic power station investment faces multiple uncertainties: policy adjustments, electricity price fluctuations, differences in lighting conditions, equipment attenuation risks... How to find certain returns in the changes has become an industry problem. LONGi BC 2.0
Battery module technology is centered on "high efficiency, strong performance, and ultra-reliability", providing photovoltaic power station investors with a "reassurance" with a validity period of up to 25 years, using technical certainty to resist market volatility risks.
High efficiency: reduce initial investment and consolidate the foundation of income LONGi BC 2.0 technology has increased battery efficiency to more than 26.6% through breakthrough structural design, and the conversion efficiency of mass-produced modules has increased to more than 24%, leading the industry. The increase in power generation has greatly reduced the land area and BOS costs required for the same installed capacity. The calculation results of three real project cases are shown below: Taking a 500MW offshore photovoltaic project in Qinhuangdao, Hebei as an example, the use of LONGi BC 2.0 modules can reduce the sea area by about 365.68 acres compared with conventional TOPCon modules, which can save the owner 8.4635 million yuan in sea area usage fees in 25 years. At the same time, the reduction in module usage also reduces BOS costs, which can save a total of 81.4775 million yuan in additional investment. The combination of the two means that the use of LONGi BC can save the owner 89.941 million yuan in initial investment compared with TOPCon.
In terms of the common flat-land scenarios of centralized power generation, taking a 200MW rural revitalization demonstration base project in Ninghe District, Tianjin as an example, the use of LONGi BC 2.0 modules can save about 189.2 acres of land compared to conventional TOPCon modules. With a reference to the rental fee of 450 yuan/mu/year, the owner can save 2.1285 million yuan in land rent in 25 years, and the BOS cost can save an additional 14.872 million yuan in additional investment, which can save the owner 17.0005 million yuan in initial investment.
Taking a 100MW mountain project in Pu'er, Yunnan as an example, the use of LONGi BC 2.0 modules can also save about 135 acres of land. With a reference to the rental fee of 600 yuan/mu/year, the owner can save 2.03 million yuan in land rent in 25 years, and the BOS cost can save an additional 5.4 million yuan in additional investment, which can save the owner 7.43 million yuan in initial investment.
Based on the above results, the conclusion that "LONGi BC 2.0 modules save initial investment" is applicable to all mainstream centralized scenarios. Weak light and shading optimization: Accurately capture the benefits of high electricity price periods The benefits of photovoltaic power stations not only depend on the power generation, but are also closely related to the matching degree of electricity price periods. LONGi BC 2.0 technology has stronger weak light response capabilities and can still work effectively in the morning and evening hours and rainy weather; the components also have special anti-shading design, which can reduce the system power generation loss caused by local shadows and avoid the "shrinkage" of benefits during high electricity price periods. Combining the above two points, the power station generates 3%-5% more power during peak hours, which can significantly increase the single watt benefits under the time-of-use electricity price mechanism. Quality escort throughout the life cycle: leveraging long-term benefits The working life of photovoltaic power stations is as long as 25 years, and the small efficiency improvement will be compounded over time. The attenuation of LONGi BC 2.0 components in the first year is ≤1%, the annual attenuation is ≤0.35%, and the temperature coefficient is -0.26%/℃, which are all at the leading level in the industry; the components are "smartly" manufactured in the only lighthouse factory in the photovoltaic industry, and the material level is continuously optimized and upgraded. The anti-hidden crack and anti-PID performance are excellent, and they have passed the rigorous salt spray, damp heat, and load tests of authoritative third-party institutions. Calculated over the entire life cycle, the reduction in power generation losses and the improvement in reliability can add an additional 1%-2% to the total power generation of the project, while reducing the burden of operation and maintenance, and increasing revenue and profits for the owner. Conclusion: Deterministic technology, the core weapon to resist uncertain risks The release of Document No. 136 means that fluctuations in trading electricity prices will become the norm. LONGi BC 2.0 has significantly reduced the cost per kilowatt-hour through the triple guarantee of "initial cost reduction + full life cycle gain + quality support". When electricity prices are at a low level, the project can still maintain a certain profitability and ensure a safety margin of income; and when electricity prices rise, the project's profit margin will be further expanded, significantly ahead of conventional products on the market. LONGi BC 2.0 is not only a technology, but also a profit commitment that crosses the cycle. Anchoring the certainty of advanced technology in uncertainty is the ultimate answer to the value gain of photovoltaic projects.
