What this type of data looks like
Photovoltaic financing daily report data comes primarily from public notices of project record filings by local energy bureaus, public disclosures from domestic photovoltaic power station development enterprises, and third-party power equipment industry data service providers. Data is updated daily, covering distributed and centralized photovoltaic projects that completed record filing or loan disbursement on that day. Each daily report document includes standard fields: project record ID, installed capacity (unit: MWp), financing amount (unit: ten thousand yuan), project location, investor entity, cooperating lending bank, actual loan disbursement date, and more. Some projects include scanned copies of record approval documents or summaries of financing agreements.
What constraints these characteristics impose on tool calling and plugins
Daily updated data sources require tool calling to be configured with a daily scheduled trigger logic. Project record ID must be used as the unique identifier to enable incremental pulling and avoid repeated processing of historical data. Standard fields include installed capacity and financing amount with attached units. Tool calling must include built-in unit validation rules to prevent unit confusion across categories. Some projects include scanned approval documents. The tool must support downloading and parsing remote attachment URLs, and handle parsing errors caused by differences in attachment formats across sources. The need for field mapping across multiple data sources requires plugin configurations to support custom field matching rules, to adapt to output formats from different data service providers.
How to configure
| Configuration Item | Recommended Value | Rationale |
|---|---|---|
request_timeout | 60 seconds | Interfaces for photovoltaic financing daily reports typically respond within 30 seconds. Setting 60 seconds covers network fluctuations and attachment download scenarios |
incremental_sync_key | project_record_id | The project record ID for photovoltaic financing daily reports is a unique and stable identifier, which can be used for incremental pulling and deduplication |
max_attachment_size | 10 MB | Scanned copies of photovoltaic record approval documents typically do not exceed 5 MB per file. Setting 10 MB covers compliant upload ranges |
field_mapping_config | Calibrated based on actual testing | Field naming varies across different data service providers. Adjust mapping relationships based on actual data sources |
schedule_cron | 0 8 * * * | Photovoltaic financing daily reports are typically updated before 8 AM daily. Setting a trigger at 8 AM matches the data source update schedule |
attachment_parse_enabled | Enabled | Some photovoltaic project financing daily reports include scanned record approval documents. Enable attachment parsing to extract key information |
The parameter values provided on this page are common recommended starting points for configuration. Actual values are affected by material format, data volume, and business rules. Specific issues require case-by-case analysis. It is recommended to test on your own samples before finalizing settings.
Three common mistakes
- An interface call returns the
Failed to fetcherror, and logs indicate that attachments cannot be downloaded. This occurs when themax_attachment_sizeparameter is not configured, or its value is set too small, preventing large photovoltaic record approval scanned copies from downloading. - Duplicate entries appear in pulled data. This occurs when the
incremental_sync_keyparameter is not set, or a non-unique identifier is used as the sync key, making correct deduplication of historical data impossible. - Parsed fields have unit confusion, such as identifying the installed capacity unit
MWpaskW. This occurs when unit validation rules infield_mapping_configare not configured, and field mapping configurations from other categories are reused directly.
How to verify correct configuration
- Manually trigger a plugin call, check if the returned results include the latest photovoltaic project financing information from the current day, and verify that project record IDs match content published on the data source.
- Check the attachment parsing switch status in the plugin configuration, upload a photovoltaic record approval scanned copy for testing, and confirm that parsed text content can be read normally.
- Wait for a full scheduled trigger cycle, then review the pulled data list to confirm there are no duplicate project record ID entries.
- Call the tool to retrieve field details for a single data entry, and verify that the units for installed capacity and financing amount match the labels on the data source.
