Photovoltaic energy storage system commissioning

What is PV commissioning?

Commissioning of PV systems involves visual observations as well as tests and measurements to verify the safe and proper operation of the system. Commissioning is performed immediately after PV installations are completed, prior to being operated and put into service for the first time.

Why should a solar installation company conduct a COM-missioning test?

These formal com-missioning activities not only promote compliance with codes and engineered plans, but also help ensure that PV systems will meet energy production estimates. In some cases, solar installation companies imple-ment common commissioning tests as part of an in-house safety or quality control program.

What are the steps of a PV system commissioning procedure?

Key steps of a PV system commissioning procedure typically include: ■ Completing final installation details. ■ Completing visual inspections. ■ Verifying compliance with NEC requirements. ■ Conducting electrical verification tests. ■ Vo/c, Is/c, insulation resistance, polarity.

Why do solar industry professionals have a long time to commission?

It’s not uncommon to find solar industry professionals flummoxed by the long timelines required to properly commission energy storage systems. A frequent cause of this is the overwhelming amount of data required to control, monitor and warranty the systems appropriately.

Do PV systems need independent commissioning & verification?

Every project pursuing LEED certification is subject to independent commissioning and verification require-ments. Many financial backers of large PV systems require independent third-party commissioning to validate their investment.

What is a reasonable expectation of PV system O&M costs?

Members of the working group have discussed these results and are currently recommending 0.5% for large systems and 1% of system initial cost per year for small systems as a reasonable expectation of PV system O&M costs. These heuristics inform an expectation of PV system O&M costs.
