In-Service Inspection

In-Service Inspection

Safeguard the longevity of your solar power assets
Successful long-term power production and meeting the planned return on investment are the goals of any power plant project. Photovoltaic (PV) power plants require regular maintenance and inspection to ensure that components and grid connectivity installations function correctly. The slightest defect or failure in a minor critical component could result in undesired downtime.
Operators, owners and investors of solar power assets require inspections to be carried out with a high level of technical expertise in order to receive evaluations and recommendations for maintenance and repair activities.
GridLynkprovides regular inspections, performance verification and preventive failure analyses to help you maximise productivity, reduce costly downtime and meet regulatory requirements.

Why are in-service inspections important for your business?
In-service inspections are necessary to ensure that your solar power assets deliver the expected power output and meet the planned return on investment of the project. They also help you to meet regulatory requirements for mandatory inspections. Inspections from a service provider with a string brand reputation can ensure a high level of acceptance of your reports and certificates. The timely recognition of repair needs will minimise the cost, ease constraints on public funds and significantly extend the life of your PV power plant.

Basis for Inspection

Like in any power plant, a solar PV plant requires the following types of maintenance

  • IEC 62446:2010 Grid connected photovoltaic systems- Minimum requirements for system documentation, Commissioning test and inspection
  • The following referenced documents are indispensable for the application of above standard. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document applies.
  • IEC 60364 (all parts), Low-voltage electrical installations
  • IEC 60364-6, Low-voltage electrical installations – Part 6: Verification
  • IEC 60364-7-712:2002, Electrical installations of buildings – Part 7-712: Requirements for special installations or locations – Solar photovoltaic (PV) power supply systems
  • IEC/TR 60755:2008, General requirements for residual current operated protective devices
  • IEC 61557 (all parts), Electrical safety in low voltage distribution systems up to 1000 V AC and 1500 V DC – Equipment for testing, measuring or monitoring of protective measures
  • IEC 61730-1, Photovoltaic (PV) module safety qualification – Part 1: Requirements for construction

Our Services

Inspection of regular maintenance

GridLynk conducts inspections in line with the detailed test procedures and to-do lists provided in the directives for the regular maintenance of PV systems.

Identified problem analysis

Our evaluation takes into consideration the client’s description of problems and the first check of all available documents and monitoring data.

Visual inspection

GridLynk’s experts conduct a visual inspection of the PV plant to identify its status and basic issues affecting its ability to function reliably and safely.

System and component inspection

GridLynk offers inspections for a wide range of PV systems, including roof-mounted systems (medium sized systems for residential and industrial roofs) and large ground-mounted systems.We also offer detailed measurements of component parameters.

Definition of improvement measures

We provide a proposal for detailed improvement measures according to the identified technical and organisational problems.

How We Do It

GridLynk will inspect Power plant for its functionality and the plant performance shall be checked. Special attention will be given to the actual installed power and system efficiency. These measurements help to detect installation problems, which can cause electrical hazard. Measurements at generator units will be conducted, compared and checked regarding plausibility to investigate the proper function of the generator.

  • Random Visual Inspection of the plant – Inspection of structure, connections, JBs etc.
  • The short circuit current and open circuit voltage will be measured at selected module strings.
  • GridLynk will determine the actual installed power, the current -voltage-curves (IV – curves) by actual measurements on randomly selected module strings.
  • GridLynk shall conduct infrared scans on selected PV Modules, connection boxes and all inverter units which help in detecting contact problems, hot spots or overheating and other fire causing hazards.
  • Dependent of the material of the module construction, the corrosion protection of the material will be investigated.
  • After successful completion of inspection and corrective action, GridLynk will issue an In-Service Inspection Report.
