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.
