All testing listed below can be performed alone or in totality through of the qualification of photovoltaic products according to IEC standard. Tests will be divided based on the necessary conditions for each test.

Tests in the field

1. Continuity of protective earthing and equipotential bonding conductors
2. Polarity test 
3. PV string combiner box test 
4. PV string – Open circuit voltage measurement 
5. PV string – Current measurement (Short circuit test - Operational test) 
6. Functional tests
7. PV array insulation resistance test
8. String I-V curve measurement
9. Voltage to ground – Resistive ground systems 
10. Blocking diode test

12. Measurement of photovoltaic current-voltage characteristics 
13. Measurement of current-voltage characteristics of multi-junction 
    photovoltaic (PV) devices 
14. Measurement of current-voltage characteristics of bifacial photovoltaic (PV) devices
15. MPPT efficiency PHOTOVOLTAIC SYSTEMS — POWER CONDITIONERS 
16. — PROCEDURE FOR MEASURING EFFICIENCY 

Tests in the lab:

1. Measurement of temperature coefficients 
2. Performance at STC and NMOT 
3. Performance at low irradiance
4. Photovoltaic (PV) module performance testing and energy rating –: Irradiance and temperature performance measurements, and power rating.

These tests are performed with several advanced equipment whose example our solar simulator (Class A+A+A+) allows us to determine the maximum power of a photovoltaic module in standard test conditions (STC) as well as different irradiances.
