What the Data for This Category Looks Like
Data sources for photovoltaic financing daily reports include national power trading center grid-connected photovoltaic project financing filing data, local energy bureau distributed photovoltaic financing publicity information, and interbank market photovoltaic enterprise credit announcements. The update schedule is daily updates, with full data synchronization for the previous day completed by 18:00 on the same day. A single data structure contains 7 fixed fields: project number, province where the project is located, installed capacity (unit: MW), financing amount (unit: ten thousand yuan), financier type, lending bank, and lending date. There are no extra extended fields, and all fields are required.
Constraints Imposed by These Characteristics on the "Model Access and Configuration" Link
The fixed field structure requires strict binding of preset field mappings during model access, to avoid result distortion caused by field misalignment. The daily update schedule requires configuring scheduled synchronization tasks, with synchronization intervals matching the data update cycle to avoid returning expired data. Vertical category numeric fields (installed capacity, financing amount) need dedicated numeric retrieval rules to improve recall accuracy. The fixed time format of the lending date requires mandatory format verification in the preprocessing link, to prevent the model from receiving abnormal time fields. The fixed full data structure requires targeted optimization of indexes for the exclusive attributes of photovoltaic projects during index construction, avoiding irrelevant data recall from general indexes.
How to Set the Configuration
| Configuration Item | Recommended Value | Rationale |
|---|---|---|
rag_top_k | Top 8-12 | Photovoltaic financing daily reports have concise single-data fields. 8-12 entries can cover core financing information while avoiding context overload |
vector_similarity_threshold | 0.72-0.85 | Installed capacity and financing amount of photovoltaic projects are strongly matching fields. Too low a threshold will introduce irrelevant projects, while too high a threshold will miss matching projects in the same region with slightly lower similarity |
sync_interval_seconds | 82800 seconds | Data updates at 18:00 daily. Setting an interval slightly shorter than 24 hours ensures one full synchronization per day |
prompt_template | Please extract information strictly in the preset field order based on photovoltaic financing daily report data, and do not add or omit fields | The fixed field structure requires the model output to strictly match the preset fields to avoid format misalignment |
parse_timeout | 300 seconds | The full data volume of photovoltaic financing daily reports is large. 300 seconds can cover preprocessing and index construction for all data |
The parameter values provided on this page are conventional recommendations used as a starting point for configuration. Actual values are affected by material form, data volume and business rules. Specific issues require specific analysis. It is recommended to conduct actual tests on your own samples before finalizing the configuration.
Three Common Misconfigurations
- Phenomenon: Non-photovoltaic field financing projects appear in retrieval results, and fields include non-preset industry tags. Cause: Dedicated index rules are not configured for the exclusive fields of photovoltaic categories (such as installed capacity in MW), and a general index model is used, resulting in insufficient recall accuracy.
- Phenomenon: Calling OneAPI returns
500 Internal Server Error, and detailed failure information cannot be obtained. Cause: Theapi_error_logconfiguration item is not enabled, and error logs are not stored to the specified directory, making it impossible to locate the specific link of call failure. - Phenomenon: After accessing the qwen3 model, the field order of the model output does not match the preset, and field missing occurs. Cause: The dedicated prompt adaptation template for the qwen3 model is not loaded, and the model output format verification rules are not configured, resulting in non-compliant format.
How to Confirm Successful Configuration
- Execute a manual synchronization task, check the index construction log, and confirm that all fields of the photovoltaic financing daily report are correctly identified and mapped to the preset fields.
- Initiate a retrieval request, check whether the returned result fields completely match the preset photovoltaic financing daily report fields, with no extra or missing fields.
- Trigger a OneAPI call, check the error log in the specified log path, and confirm that there are no uncaught call exceptions.
- Switch to the qwen3 model to conduct a test, and confirm that the model output format meets the preset field order and content requirements.
