工商业屋顶N型BIPV和P型BIPV户外应用监测数据

通过监测工商业屋顶N型BIPV（光伏建筑一体化）和P型BIPV的户外发电量数据，反映出N型TOPCon（新型组件）和P型PERC（传统组件）在相同工作条件下（规格、数量、逆变器、时间、地点、朝向、工作温度）的光伏发电规模及可再生绿色电力最大增长潜力，从而有助于业主、EPC客户筛选BIPV产品。BIPV发电量的算法规则采用单瓦发电量的计算对比，是为了排除因组件功率不同导致的发电数据差异，实现更加精确的由组件技术所带来的长期发电表现： 1.数据来源：通过直流电表来监测光伏组串的实时发电量； 2.数据整理：记录监测周期内的实时发电量累计叠加并汇总，反应光伏组件在实际运行过程中的发电表现性能； 3.模型选择：单瓦发电量（kWh/kW）=月累计发电量（kWh）＊1000/（组串组件平均测试功率（W）*组件数量），单瓦发电量增益=（N型单瓦发电量/P型单瓦发电量-1）*100%，实验组通过控制组件的朝向、支架类型等因素保持一致，对晶科不同类型组件的发电性能进行监测和分析； 4.数据应用：结合电站运行维护记录，对采集数据进行筛选处理。为保证各实验组发电量对比的准确性，消除因逆变器启动时间、阵列间遮挡损失等环境因素造成的发电量差异，选取全天时发电量数据进行数据对比分析，并根据现场运维记录、数据波动等因素筛除异常数据，统计各实验组阵列发电量数据。 5.数据成果：根据算法规则得出N型BIPV较P型BIPV的发电增益数据，有助于业主、EPC客户筛选BIPV产品。This dataset monitors outdoor power generation data of N-type and P-type Building-Integrated Photovoltaic (BIPV) modules installed on commercial and industrial rooftops, aiming to reflect the photovoltaic power generation scale and maximum growth potential of renewable green electricity of N-type TOPCon (new-generation modules) and P-type PERC (traditional modules) under identical operating conditions including specifications, quantity, inverters, time, location, orientation and operating temperature. This helps property owners and EPC clients screen appropriate BIPV products. The algorithm for calculating BIPV power generation adopts comparative analysis based on power generation per watt, which is designed to eliminate power generation differences caused by varying module power ratings, enabling more precise evaluation of long-term power generation performance attributed to module technologies: 1. Data Source: Real-time power generation of photovoltaic strings is monitored via DC electricity meters; 2. Data Organization: Cumulative real-time power generation within the monitoring period is recorded and aggregated to reflect the actual power generation performance of photovoltaic modules during operation; 3. Model Formulation: Power generation per watt, expressed as kWh/kW, equals monthly cumulative power generation (kWh) × 1000 / (average test power of the modules in the string (W) × number of modules); Power generation gain per watt equals ((N-type power generation per watt / P-type power generation per watt) - 1) × 100%. The experimental group maintains consistent variables including module orientation and support type to monitor and analyze the power generation performance of different module types from JinkoSolar; 4. Data Application: Collected data is screened and processed in combination with power station operation and maintenance records. To ensure the accuracy of power generation comparison between experimental groups and eliminate discrepancies caused by environmental factors such as inverter startup time and shading losses between arrays, all-day power generation data is selected for comparative analysis. Abnormal data is filtered out based on on-site operation and maintenance records, data fluctuations and other factors, and the power generation data of each experimental group's array is statistically compiled; 5. Data Outcomes: The power generation gain data of N-type BIPV compared to P-type BIPV is derived per the algorithm rules, which supports property owners and EPC clients in screening BIPV products.
