What the data for this category looks like
Data for photovoltaic financing daily reports is sourced from public financing record announcement platforms for the power equipment industry and photovoltaic project financing loan information published by local energy regulatory agencies. The update cadence follows a daily T+1 schedule: the previous natural day’s financing data is released early the next morning. Documents use a structured format, containing complete financing information for individual photovoltaic projects. Fields include project ID, project name, installed capacity (unit: MWp), financing amount (unit: ten thousand yuan), loan subject, record date, project location, financing purpose, and more. Each record has a fixed structure, with no nested complex unstructured content. A single daily batch of data typically covers dozens to hundreds of projects.
What Constraints These Characteristics Impose on HTTP Interfaces and External Systems
The daily update cadence of photovoltaic financing daily reports requires interfaces to support precise date-based data filtering. This avoids bandwidth waste caused by pulling full historical data. Structured fields and units require interface requests to specify a return format with clearly labeled unit-bearing numeric fields. External system integrations must pre-adapt parsing rules for exclusive units such as MWp and ten thousand yuan. The large single-batch data volume requires interfaces to support paginated data pulling, and to adapt to request body size limits for bulk data. Photovoltaic financing projects have high mutual relevance, so external system calls must avoid unlimited recall of entries. This prevents interface response overload.
Configuration Settings
| Configuration Item | Recommended Value | Rationale |
|---|---|---|
api_request_timeout | 300 seconds | Photovoltaic financing daily reports have long single-batch data parsing times. The default timeout is insufficient to complete a full request. |
UPLOAD_FILE_MAX_SIZE | 500 MB | Structured export files for single-day photovoltaic financing daily reports typically range in the hundreds of MB. This setting accommodates bulk data upload needs. |
PARSE_FILE_TIMEOUT_SECONDS | 600 seconds | Photovoltaic financing daily reports contain many industry-specific fields and long-text financing descriptions. Parsing times are longer than general scenarios. |
retrieval_top_k | Top 10 entries | Photovoltaic financing projects have high keyword matching accuracy. Excessive recall increases processing burden on external systems. |
similarity_threshold | 0.75–0.85 | Maintain a reasonable matching range. This avoids recalling unrelated power equipment financing data. |
batch_request_size | 50 entries per request | Adapt to external system rate limiting rules. This prevents triggering interception due to overly large single request data volume. |
The parameter values provided on this page are common recommended starting points for configuration. Actual values are affected by material form, data volume, and business rules. Specific issues require case-by-case analysis. It is recommended to test against relevant samples before finalizing settings.
Three Common Configuration Mistakes
- An
Error: write EPROTOerror is returned when calling the API. This occurs due to incorrect HTTPS certificate verification configuration, or a missing valid API key parameter in the request header. - Non-streaming requests are automatically disconnected after 180 seconds. This occurs because the
api_request_timeoutconfiguration item was not adjusted, and the platform's default timeout setting was used, which cannot accommodate the parsing time of photovoltaic financing daily reports. - Fields such as installed capacity and financing amount are empty after uploading a photovoltaic financing daily report file. This occurs because the exclusive field naming rules for photovoltaic financing daily reports were not matched, and the platform's default parsing logic cannot recognize field formats with units.
How to Verify Proper Configuration
- Initiate an API request filtered by a specified date. Check that the returned results include exclusive fields such as project name, installed capacity, and financing amount, and that the field units comply with photovoltaic industry standards.
- Upload a complete single-day photovoltaic financing daily report file. Check that no size limit exceeded error related to
UPLOAD_FILE_MAX_SIZEis triggered in the interface or return logs. - Initiate three consecutive polling requests at 1-hour intervals. Check that the update time of the returned data complies with the T+1 update cadence, and that there is no repeated pulling of old data.
- Adjust
similarity_thresholdto 0.8, then initiate a recall request. Check that all returned results are photovoltaic-related financing projects, with no unrelated category financing data mixed in.
