Solar Commissioning and Re-Commissioning

Solar Commissioning and Re-Commissioning

Solar commissioning is part of the Field Acceptance Test. Solar commissioning is performed in order to establish an as-built baseline for the system as well as ensure that the system is safe and built to code.

Solar facilities make great investments, but only if properly maintained for performance and safety. Re-commissioning (PV-RCx) of photovoltaic solar assets is fundamental to high performance solar systems that are built to last for decades.

Solar Commissioning

Our team of engineers and technicians specialize in re-commissioning systems that have been poorly maintained or are underperforming due to component failure. In nearly every situation, our team is able to rehabilitate even the poorest performing systems through rigorous testing and implementation of any recommendations. If you suspect your system is under-performing, please call us or complete the form below.

Solar Commissioning Phases

Electrical Testing

Solar commissioning and solar re-commissioning (PV-RCx) includes electrical testing of electrical circuits included in the solar system. All module strings, combining load centers and inverters are checked for connectivity, voltage, amperage and over current protective device operation.

Through rigorous data collection and analysis, HelioPower’s Field Acceptance and Commissioning Tests (FACTS) are able to identify underperforming electrical components and guide our clients to make smart, cost effective repair decisions quickly and efficiently.

Performance Evaluation

Parallel to the technical re-commissioning effort, our engineering group evaluates system performance. By comparing expected to actual energy harvest to date, baseline performance ratios are developed, an assessment of historical performance is prepared, and comparisons to Minimum Guaranteed Generation (MGG) are provided, if appropriate.

In succeeding years, this baseline production figure is used in our O&M service to track system degradation and is used as a key indicator for any changes to system output.

Mechanical Inspection

Most solar facilities have few moving parts, however foundations and racking systems must be inspected and maintained to ensure safe and reliable support of the array. During solar commissioning and re-commissioning tests, structural integrity reviews are critical – particularly in high wind-load or earthquake-prone areas.

In many areas, corrosion due to proximity to salt water can cause devastating mechanical failures which can lead to unsafe conditions and increase system owner liabilities. HelioPower PV-RCx includes a thorough inspection and report of all support systems for ground and roof mounted assets.

Report And Recommendations

A thorough, professional report of findings and a detailed list of any corrective recommendations are included with each PV-RCx. The recommendations are grouped into three classifications, in order of criticality: hazardous, preventative or performance.  Any recommended action is fully explained and enumerated.

The PV-RCx report is a substantial document including photos, performance evaluations, forecasts and hazard analysis with recommendations for further action.
