Commissioning software for utility-scale solar where hundreds of thousands of modules, thousands of strings and dozens of inverters all have to prove out before grid connection.

A utility-scale array is not one asset: it is thousands of strings, hundreds of combiner boxes, dozens of central or string inverters, tracker rows with their own motor and controller, and a substation stepping the whole plant up to grid voltage, each installed by a different crew across weeks of construction.

When string IV curve results, inverter commissioning records and tracker functional tests sit in separate EPC subcontractor spreadsheets, nobody can answer a basic question at the pre-COD readiness review: which block is actually ready to energise today.

Deskely tags every string, combiner box, inverter and tracker row individually, so the site can see exactly which block is blocking energisation instead of being told the plant is '92% mechanically complete'.

String IV curve testing, polarity checks and insulation resistance testing are captured against each string and combiner box before an inverter station is cleared for DC energisation.

Inverter commissioning proves AC output, anti-islanding protection and grid code compliance under increasing load, while tracker rows are functionally tested for backtracking, stow and wind-response logic before the row is released to production.

Vendor punch from the module supplier, the inverter OEM and the tracker contractor is logged at the specific string or row, so ramp-up is not blocked by an unrelated open item three blocks away.

Module defects on a utility-scale array rarely fail visibly. A cracked cell, a delaminating backsheet or a bad solder bond shows up as a hot spot on an IR thermography flyover or a dark cell on an electroluminescence (EL) scan, often on a sample taken long after the module was installed, torqued and strung into a combiner circuit with a hundred others from the same delivery batch.

Deskely ties every module's serial number to its manufacturer lot, its string and its position on the layout, so when a thermography drone survey or an EL scan flags a hot spot or a micro-crack pattern, the finding is logged against that exact module and the site can immediately see every other module from the same batch across the plant rather than treating each hot spot as an isolated event.

Grid code compliance and reactive power tests at full plant output require ramping hundreds of inverters in a coordinated sequence while the utility observes voltage and frequency response at the point of interconnection; Deskely records each inverter's contribution to that test run against its own tag, so a single inverter tripping the sequence is traceable without re-running the whole plant test.

Beyond PCS commissioning and fire suppression proving, a battery energy storage system has to demonstrate its rated energy capacity and round-trip efficiency against the OEM's guaranteed values through full charge-discharge cycle testing, typically witnessed by the owner's engineer because it is the figure the performance guarantee and any capacity-based revenue contract is measured against.

Where UL 9540A large-scale fire testing or an equivalent thermal runaway propagation test was performed at the module or unit level to support the fire suppression design, Deskely holds that test report against the specific battery module type and container configuration on site, so the AHJ can verify the installed system matches what was actually tested rather than a similar-looking configuration.

Arc flash studies covering the DC battery bus and the AC side of the PCS are held against the specific switchgear and PCS tags, because the incident energy calculations directly drive the PPE requirements the O&M provider's electricians will be working to for the life of the system, not just at commissioning.

Environmental permits for floating solar installations typically require ongoing monitoring of aquatic ecology, water quality beneath the array and, on some sites, bird or wildlife exclusion measures, none of which is a one-time commissioning check but a recurring obligation the asset owner has to keep evidencing for the life of the permit.

Deskely holds anchor line inspection cycles, biofouling assessment on pontoon undersides and mooring hardware corrosion checks as their own recurring routine against each mooring point and pontoon block, distinct from the initial mooring load test, because a line rated correctly at installation can still degrade from biofouling drag or chain wear well before its design life is up.

Where the permit or the marine structural engineer of record requires periodic re-verification of mooring tension against the original design load, Deskely's routine schedule flags an overdue re-check the same way it flags overdue preservation on idle equipment, so the marine inspection obligation doesn't quietly lapse once the commissioning team has moved to the next site.
