PV projects – Consulting and engineering

We offer consulting and engineering services specialising in photovoltaic projects. We work with a team that has extensive experience as technical advisor to both developers and financial institutions and its own independent laboratory specializes in quality control of photovoltaic (PV) modules and on-site inspections and performance tests of PV plants. The engineering team designs and optimizes large photovoltaic projects as well as roof-top installations.

The REMOTE OPERATIONS CENTER (ROC) is responsible of controlling and monitoring the performance of the PV systems all year long.

The LABORATORY is capable of testing 200 modules per week and is equipped with state-of-the-art instrumentation: class AAA solar simulator used to measure the max power of PV modules (according to international standard IEC 60904); thermo-graphic cameras to detect resistive hot-spots; and an I-V Curve tracer to check electrical strings of PV Modules on-site.

  • Preliminary Acceptance Test (PAT) and Final Acceptance Test (FAT).
  • Analysis of monitoring data.

Our inspections and testing are based on the following international standards:

  • IEC 61215: Crystalline silicon photovoltaic (PV) modules for terrestrial use. Design qualification and type approval.
  • IEC 61646: Thin-film photovoltaic modules for terrestrial use. Design qualification and type approval.

The Laboratory offers its services to carry out the following tests:

  • Visual inspection (section 10.1 of the standard UNE-EN 61215:2005/
    IEC 61646:2008).
  • Thermographic inspection (internal procedure)
  • Insulation test (section 10.3 of the standard UNE-EN 61215:2005
    IEC 61646:2008).
  • Maximum power determination (section 10.2 of the standard UNE-EN 61215:2005 /
    IEC 61646:2008).
  • Performance at low irradiance (section 10.7 of the standard UNE-EN 61215:2005 /IEC 61646:2008).
