Our Services

1. PV Module Quality Testing

The Quality testing of PV modules provides the client with confirmation that the module specifications promised by the supplier have been met. This is critical information for operators to ensure that power plant components can produce the estimated power outputs.

Quality Assurance

Baseline measurements of PV modules after transport and before installation to verify product quality.

Failure Analysis

Inspection of PV modules to determine degradation and damage due to extreme weather events. Modules must be removed from racks to test.

Warranty Check

Support for technical due diligence during the sale of an asset or measurements to support a warranty claim.

PVinsight can complete the following tests either on-site at the PV plant or at the fixed laboratory in Gqeberha, South Africa.

Visual Inspection

Inspection of the PV module for defects and damage according to defined criteria.

Insulation Testing

Ensure electrical insulation between the PV circuit and structural elements of the module.

Electroluminescence Imaging

Identification and analysis of potential performance-degrading defects in the PV modules.

Peak Power Measurement

Measures the electrical performance of the PV module by measuring the characteristic current voltage (I-V) curve of the module output using a solar simulator.

Low Irradiance Measurements

To determine the electrical performance of the module with a variable load at 25° C and 200W/m². Measurement of Maximum Power at low irradiance used to monitor module degradation and the effects of PID-shunting are more pronounced at low irradiance.

Wet Leakage Testing

To evaluate the insulation of the module under wet operating conditions and verify that moisture from rain, fog, dew or molten snow does not enter the active parts of the module circuitry, where it might cause corrosion, a ground fault or a safety hazard.

2. Field Inspections

The performance of the installed PV modules has a direct effect on the profitability of the PV installation. Field inspections are vital for both Newly Built and Operational PV plants.

Commissioning Tests

Quality control of PV modules is essential both pre- and post-installation and to ensure the installed system meets the requirements. This data can be used for quality disputes to identify at what stage damage occurred.

Degradation Testing

Tests are required for the assessment of Extreme Weather events like Hail, as well as the Due Diligence process, and PV plant repowering.

Troubleshooting and Maintenance

Identifying issues that are limiting production.

The Quality testing of PV modules provides the client with confirmation that the module specifications promised by the supplier have been met. This is critical information for operators to ensure that power plant components can produce the estimated power outputs.

Field Visual Inspection

Visual inspection of Modules in-situ to identify defects and damage according to a defined criteria.

Peak Power Measurement of Strings and Modules

The measurement of characteristic current voltage (I-V) curve for individual modules or strings in order to determine the plant performance.

Field Electroluminescence Imaging

EL imaging of modules without removign them from the strings.

Field Electrical Insulation Testing

Measurement of the Insulation Resistance (Riso) of stings in order to determine the safety of the system.

3. Consulting

4. Glint and Glare

Reflected sunlight on Solar modules ​from shiny surfaces can affect​ the safety and ​residential amenity in surrounding areas.​ Glint is a momentary flash of light; it can be experienced by an observer passing a solar panel at speed such as a motorist. Glare a continuous source of excessive brightness. Meaning that observer is stationary and is placed in the path of reflected sunlight from the face of the panel.

New solar project applications may need to be accompanied by a Glint & Glare Impact Assessment Report with specific relevance to aviation & aircraft operations. PVinsight can assist with these reports, and can provide suggestion on Glint and Glare mitigation measures.
