Commissioning & Recommissioning

Solar Commissioning and Recommissioning Services

Solar Commissioning is part of the Field Acceptance Test process. Solar commissioning is performed to establish an "as-built" baseline for the system, ensuring that it is safe and built to code. Solar facilities are great investments, but only if properly maintained for performance and safety. The recommissioning process (PV-RCx) of solar photovoltaic (PV) assets is fundamental to high performance solar systems that are built to last for decades.

Benefits of Solar Commissioning & Recommissioning

Declining system performance can occur overtime and commonly arise when a solar system undergoes a change in ownership. Recommissioning provides a systematic approach to ensuring your system functions optimally. Here are key benefits of recommissioning:

  • Finding under-performing defects
  • Prevents loss of energy
  • Track system degradation
  • Fewer solar maintenance concerns
  • Preventative maintenance is cheaper than emergency maintenance
  • Improved comfort levels
  • Extended equipment life

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.

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.

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.

Report and Recommendations

A thorough, professional report and a detailed list of any corrective recommendations are included with each PV-RCx. The recommendations are grouped into three classifications:

  • Hazardous
  • Preventative
  • Performance.

Any recommended action is fully explained and enumerated. The report includes photos, performance evaluations, forecasts and hazard analysis with recommendations for any further actions required.

Consult a Professional

Our team of engineers and technicians specialize in recommissioning systems that have been poorly maintained or under-perform due to component failure. In nearly every situation, we are 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 contact us today.
