Renewable energy solutions for a sustainable tomorrow

What each engagement actually covers

The packages are built around the work we do most often on distributed PV sites. Each one has a clear scope, so you know what gets inspected, what gets documented, and what you walk away with.

Commissioning Support

For new plants going through final checks. We verify string voltages against the design, confirm polarity at every combiner box, and run through the inverter startup sequence with your team.

  • String sizing and voltage verification
  • DC switchgear and combiner box checks
  • Commissioning report with test results

Typical duration is two to five days on site, depending on plant size and how many inverters need individual attention.

Troubleshooting & Diagnostics

When a plant is underperforming or throwing fault codes you have not seen before. We work through the inverter logs, inspect the DC side, and isolate the root cause rather than swapping parts blindly.

  • Inverter fault code analysis and reset
  • Thermal scanning of combiner boxes
  • Performance ratio data logging review

Most diagnostic visits are completed in a single day, with a written summary of findings and recommended next steps.

Compliance & Documentation

For plants that need to meet Eskom grid code requirements or municipal approval conditions. We review your protective relaying coordination, check the paperwork, and flag anything that will not pass inspection.

  • Grid code compliance gap assessment
  • Municipal approval paperwork review
  • Protection relay coordination check

This package is usually spread over a week, as it involves document review and sometimes coordination with the local municipality.

Service packages built around field reality

Not every plant needs the same level of attention. These packages cover the common situations we walk into, from a single inverter throwing the same fault every week to a full commissioning audit before handover. Each one has a clear scope, so you know what gets checked, what gets documented, and what you walk away with.

Fault Response

For when a specific inverter or string is underperforming and the error log does not tell the whole story. We arrive with the right meters and a plan.

  • On-site diagnosis of inverter fault codes and DC-side issues
  • String voltage and current verification at the combiner box
  • Thermal scan of DC switchgear to spot loose connections
  • Written fault report with root cause and recommended fix

Performance Audit

A deeper look at why a plant is generating less than the model predicted. Useful when cleaning schedules are not the obvious culprit.

  • Review of logged performance ratio data against expected yield
  • Soiling loss assessment on bifacial modules, front and rear
  • String sizing check for voltage rise and clipping issues
  • Priority list of losses ranked by impact on annual yield

Commissioning Support

For EPC contractors who need an independent set of eyes before the plant is handed over and the warranty clock starts ticking.

  • Verification of string configurations against the design pack
  • Protective relaying coordination and trip setting review
  • Eskom grid code compliance check on paperwork and settings
  • Punch list of items to resolve before final acceptance

Not sure which package fits the situation? Read through the approach we take on site or get in touch with the specifics of your plant. We will tell you straight whether you need a full audit or just a focused fault response.
