Installation Verification
The SunPeak commissioning team first visually confirms that all installed components are consistent with the project drawings and specifications. This includes checks on solar modules, inverters, and racking, overcurrent protection devices, wiring, and all monitoring equipment.
Quality Inspection
In addition to verifying the correct parts were installed, the commissioning team ensures the installation quality meets all required electrical codes and safety standards. Each part of the system is inspected to identify and flag any issues that do not meet the highest standard of workmanship. Any flagged items are documented and reported to the installation team for remediation. By proactively addressing potential issues that may affect the safe operation of the system over its lifetime, the commissioning process provides better value for customers and makes subsequent third-party inspections of the system more efficient.
System Testing
In addition to visual inspections from SunPeak and local municipalities, each part of the PV system must be isolated and tested to demonstrate proper operation. Insulation on electrical wiring is tested for defects that could lead to short circuits or ground faults. Solar panels are tested with an I-V curve tracer that graphs the panel’s performance to verify its power output against its nameplate rating. Voltages are read at each electrical component to ensure they will operate within the correct voltage range. Circuit breakers and disconnects are tested to confirm the correct circuits will de-energize in the proper timeframe when exposed to the rated current levels. The baseline data from these tests is documented in a commissioning report that is provided to the client once the project is completed. In the event of a future warranty claim, these commissioning test results demonstrate the equipment was installed properly but no longer performs to the manufacturer warranty standards.
