6 FAQs about [Photovoltaic inverter inspection record table]

What is a PV inspection reference?

This inspection reference details most of the issues that relate to the PV system during the inspection process.

What do you need to know about a PV system?

PV system markings, labels and signs according to the approved plan. Connection of the PV system to the grounding electrode system according to the approved plan. Access and working space for operation and maintenance of PV equipment such as inverters, disconnecting means and panelboards (not required for PV modules) (CEC 110.26).

Do PV system commissioning standards require performance testing?

This best practice guide is PV System Commissioning or re-Commissioning Guide Supplement to characterize and maximize PV system performance. If a PV system is commissioned using industry standards, then it should produce as much energy as was expected, right? No, PV industry commissioning standards do not call for performance testing.

What happens if a PV inverter fails?

An insulation failure in a PV system circuit presents dual hazards of fire and lethal electric shock. Insulation failures can also impact the energy production of the system by tripping the GFDI (ground fault detection and interruption) device and taking the inverter offline.

How to evaluate PV system capacity?

A simple method to evaluate the PV system capacity is to determine the nominal DC rating of the system at STC, measure POA irradiance, calculate cell temperature based on module back-side or ambient temperature using Sandia model, and estimate/calculate/determine values for the derate factors familiar to the industry.

What are the requirements for PV installation?

PV installation shall comply with requirements of the standard plan. PV system operating at 80 volts or greater shall be protected by a listed DC arc fault protection. (CEC 690.11) All work done in a neat and workmanlike manner. (CEC 110.12) 10. DC modules are properly marked and labeled.
