Monitoring the Production of Existing Solar Installations
1. Initial Diagnosis of the Solar Installation
-
Use PVGIS.COM to assess expected production based on location and installation characteristics
(orientation, tilt, capacity). Compare these results with actual production to identify any discrepancies.
2. Equipment Verification
- Solar Panels: Examine the integrity of the panels and connections.
- Inverter: Check error indicators and alert codes.
- Wiring and Protections: Look for signs of overheating or corrosion, check the insulation of cables.
3. Essential Electrical Measurements (performed by a qualified electrician)
-
Open Circuit Voltage (Voc) and Production Current (Imppt):
Measure values on the panels to verify compliance
with the manufacturer's specifications. - Isolation Fault Detection: Test for faults between the panels and ground using a voltmeter.
4. Customization of Simulations
- Tilt and Orientation: Ensure that the panels are installed according to recommendations to maximize solar exposure.
- Shading: Identify any sources of shade that may affect production.
5. Identification and Resolution of Common Failures
- Low Production: Check sunlight exposure and use tools like a solarimeter to measure irradiance.
- Inverter Issues: Analyze error codes and check the history of overvoltages or undervoltages.
6. Performance Monitoring
- Install an intelligent monitoring system to track real-time production and receive alerts in case of abnormal drops.
7. Preventive Maintenance
- Schedule regular inspections to check the condition of the panels, cables, and electrical connections.
- Regularly clean the panels to ensure their efficiency.
