Why do solar photovoltaic plants need verification & inspection services?

For this reason, verification and inspection services in solar photovoltaic plants are essential to ensure the quality of the modules and check their performance. This is especially relevant during the construction and development phases of the project, as well as in the subsequent operation.

What services are provided at a photovoltaic plant?

Inspection of container loading. Services on site at photovoltaic plants (Post-shipment): these services are carried out after transport from origin to where the client requires it, whether at the plant, destination port or any other location. The following tests are included at the client's request:

Why are photovoltaic panels not a good quality?

Due to the high number of photovoltaic panels required for the construction of new solar plants, cases have been observed where the final quality of the product is not as expected. This may be due to manufacturing defects, transport or handling problems, incorrect installation or inadequate maintenance.

How many photovoltaic modules can a laboratory test per day?

This laboratory can test more than 200 photovoltaic modules per day with an uncertainty of less than 3%. Due to its characteristics, it is capable of testing modules of up to 1400 x 2700 mm of different types (high efficiency crystalline modules, bifacial modules, thin film modules and PERC or HJT solar cells).

How to check the voltage of PV modules connected in series?

For checking the voltage of PV modules connected in series. Check the operation and installation of control devices such as relay switches and circuit breakers. Test the insulation resistance to ensure electrical safety. All Category 1 tests must be completed and passed before moving on to the additional Category 2 tests.

How do I know if a PV module is faulty?

By knowing the deviation of the temperature, problems like the bypass diode in the PV arrays can be detected. Additional inspections are also available for inspections outside Category 1 and Category 2. Measure the resistivity according to the technical documentation provided by PV module manufacturer.
