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. This Commissioning Guide outlines methods to use during commissioning to characterize and maximize PV system performance.
Inverters and transformers shall be commissioned by their manufacturer or an authorised representative of the manufacturer, using the manufacturer’s specified procedures. Commissioning reports shall be issued in a format provided by the manufacturer.
guarantee system performance or verify as-built conditions. Whether you measure your project size in kilowatts or megawatts, understanding the key concepts and processes for commissioning PV systems increases your bottom line and your clients’ satisfaction. By Nate Goodell, David Tedeyan and Gordon Woodcock Courtesy Taitem Engineering.
You can calculate expected annual production by multiplying the 10-kW array x 6 peak sun hours x 365 days per year x 0.85 (15% derating due to power losses in wiring and inverter). This array should produce 18,615 kWh of energy for us per year, or 51 kWh per day.

6 FAQs about [Photovoltaic inverter commissioning conditions]
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 is PV commissioning?
Commissioning is the process of assuring that all systems and components of a PV plant are designed, installed, tested, operated, and maintained according to the operational requirements of the project’s owner or final client.
What is a commercial PV & inverter information kit?
The purpose of this document is to organize and highlight details that are essential during the construction and commissioning phases of a Commercial PV system with SolarEdge inverters. For additional support contact your Commercial Program Manager. This information kit contains links to all documents relevant for your SolarEdge installation.
What does commissioned PV mean?
INTRODUCTION Commissioning is the process of assuring that a PV plant is safe, meets design objectives, and functions and produces energy in accordance with the owner’s expectations. If a PV system is commissioned according to industry standards, then it must be performing as expected, right? Not necessarily.
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 commissioning inverter?
Many incentive programs, certification entities and installation manuals use the term commissioning generically to describe a set of start-up or closeout pro-cedures. In this informal context, a system installer might verify field connec-tions and ac and dc voltage levels before “commissioning” an inverter.
