The work
A system is not finished when the last panel is clamped. It is finished when somebody has proved it works. Commissioning is the set of checks that turns an installed array into a system the owner and the utility can both rely on: open circuit voltage and polarity on every string, insulation resistance where it matters, torque verified on the terminations, grounding continuity confirmed, the inverter configured for the right grid profile, and the monitoring reporting real numbers to an account the owner can actually log into. Then the output gets measured against what the array should be producing for that time of day, that season and that irradiance, so that a shortfall is caught on the first afternoon rather than in a utility bill eight months later. We do this on our own installs and we do it for solar companies who need a crew to close out theirs.
What is included
- Open circuit voltage and polarity checked on every string
- Terminations torque verified and grounding continuity confirmed
- Inverter configured for the correct grid profile and the array in front of it
- Monitoring set up and reporting to an account the owner can log into
- Measured output compared against what the array should be making
How we run it
- 01
Electrical checks
String voltages, polarity, insulation where required, torque and grounding continuity.
- 02
Inverter setup
Grid profile, string configuration and firmware set for the system it is running.
- 03
Monitoring
Portal configured and reporting, with the owner's own login working.
- 04
Performance check
Measured output against expected output for the conditions, and a written record of it.
Asked about this
Will you commission a system somebody else installed?
Yes. We are regularly brought in by solar companies to close out installs their own crews have built.
What do I get at the end of it?
A working system, a monitoring login that is yours, and a record of the readings taken so there is a baseline to compare against later.
