Commissioning support
for PV power plants
Manage the entire commissioning process in one workspace, from audits and documentation to PAC and FAC handover.
Streamline PV plant handover
Managing commissioning across scattered files and tools creates unnecessary technical risk and delays
No single source of truth
With documentation scattered across emails and folders, it’s difficult for EPCs, investors, and O&M teams to stay aligned.
Unclear ownership of issues
Managing punch lists manually leads to missed deadlines and lack of accountability for resolving critical site defects.
Limited readiness visibility
Without a structured environment, tracking progress toward PAC/FAC milestones becomes a guessing game instead of a data-driven process.
Late-stage technical risk
A lack of real-time oversight means technical problems often surface only at the final handover, leading to costly delays.
Comprehensive commissioning process
Solar Spy structures the entire commissioning process.
From the first audits and performance checks, through PAC, and final FAC acceptance.
PAC Phase
PAC, or Preliminary Acceptance Certificate, confirms that the installation is ready
to be handed over after the main works and tests have been completed.
Disconnection and configuration audit
Verification of the correct connection of all key installation components.
Initial performance study
Assessment of installation performance and identification of energy losses at an early stage.
Pre-PAC inspection
Detection of defects that should be removed before the official acceptance.
Official PAC inspection
Confirmation of workmanship quality and compliance with acceptance requirements.
Final PAC performance study
Summary of results and preparation of the project for completion of the PAC stage.
FAC Phase
FAC, or Final Acceptance Certificate, closes the commissioning process after the monitoring
period and confirms that the facility is fully ready for operation.
PAC–FAC period monitoring
Ongoing monitoring of the installation’s operation and detection of irregularities after preliminary acceptance.
Internal inspection, if required by the schedule
Additional technical inspection performed before final acceptance.
Official FAC inspection
Confirmation of the installation’s quality before the final handover of the facility.
Final FAC performance study
Final verification of the farm’s performance and readiness for operation.

Full visibility into the
commissioning process
Monitor progress in real time and manage every stage of the photovoltaic farm acceptance process.
Process progress in a single view
Stage statuses, current progress, and key process milestones are visible without switching between spreadsheets and messages.
FAC / PAC readiness
The team can see which conditions have been met and which items still need to be completed before the next acceptance stage.
Documentation readiness
Missing documents, required attachments, and the overall documentation readiness of the project are visible in one place.
Critical issue tracking
Open items, priorities, and corrective actions are organized within a single process structure.
What do you gain?
Less chaos, better control over the process,
and greater project readiness for acceptance
Process control
Statuses, stages, dependencies, and decisions in one place.
Documentation control
Full visibility into document completeness and acceptance requirements.
Fewer risks and delays
Faster detection of missing items, gaps, and critical points.
Better readiness for PAC and FAC
Monitoring of tests, requirements, and readiness for the next stages.
Collaboration across all parties
One process structure for the investor, EPC, asset manager, and advisors.
Greater predictability of acceptance
Less chaos at the end of the process, more control earlier on.
Frequently Asked Questions
What is Solar Spy's commissioning support for photovoltaic farms?
It’s a single environment for running the entire PV installation commissioning process – from the first audits and documentation, through the PAC phase, to monitoring and FAC handover. Instead of scattered files and tools, the team works within one consistent process structure.
What problems does Solar Spy's commissioning support solve?
Four main ones: no single source of truth (documentation scattered across emails and folders), unclear responsibility for defects (manual lists lead to missed deadlines), limited visibility into project readiness (tracking PAC/FAC milestones turns into guesswork), and technical risk that only surfaces late in the process, leading to costly delays.
What is the PAC phase, and what steps does it include?
PAC (Provisional Acceptance Certificate) confirms the installation is ready for handover after the main works and tests are completed. It includes five steps: current-configuration audit, initial performance check, pre-PAC inspection, official PAC inspection, and final PAC performance check.
What is the FAC phase, and what steps does it include?
FAC (Final Acceptance Certificate) closes the commissioning process after the monitoring period and confirms the site is fully ready for operation. It includes four steps: PAC-FAC monitoring period, internal inspection (if required by the schedule), official FAC inspection, and final FAC performance check.
How does Solar Spy provide full visibility into the commissioning process?
The platform brings together stages, documents, tests, defects, and handover statuses in a single place, so the team sees the whole process, not just individual tasks. This includes: process progress in one view, PAC and FAC readiness, documents under control, and a list of defects and critical points.
How does Solar Spy help manage project documentation?
The system shows, in one place, missing items, required attachments, and the project’s documentation readiness level, instead of requiring you to search through scattered emails and folders.
How are defects and critical points tracked throughout the process?
Open items, priorities, and repair actions are organized within a single process structure, which eliminates unclear responsibility and lets you track the resolution of critical defects on site.
Who uses the shared commissioning process structure?
A single process structure covers all parties involved – the investor, the EPC contractor, the asset manager, and advisors – so everyone works from the same, up-to-date data.
What real benefits does implementing Solar Spy's commissioning support bring?
Less chaos and better process control: statuses, stages, and decisions in one place, full visibility into document completeness, faster detection of gaps and critical points, better preparation for PAC and FAC, and greater handover predictability – less chaos at the end of the process, more control earlier on.
