Solar PVYieldon the Record
The build is energized. Now every point of performance ratio you lose to soiling, a stuck tracker, or an open string is revenue that never reaches the grid. POD puts the operating day on the record, spoken from the array.
Two numbers run a solar plant
Yield is the revenue. Performance ratio is how much of the available sun you actually captured. A clean array on a clear day should hit its P50. When it does not, the cause is usually small and quiet — soiling building on the west rows, one inverter derating in the heat, a string offline since Tuesday. The O&M report is the record of what the plant produced, what held it back, and what you did about it.
What an O&M report captures
A generic maintenance log holds none of these. A solar O&M report has to.
Production vs P50
MWh produced against the P50 forecast — the number the asset manager and the lender both read first, day by day.
Performance ratio & availability
PR, plant availability, and which blocks were curtailed or down — the health of the array behind the headline yield.
Inverter & string faults
Inverter derates and trips, offline strings, combiner alarms — the faults that quietly bleed a percent of yield if left open.
Soiling & cleaning
Soiling loss building across the array and the cleaning cycles that recover it — the difference between P50 and what you shipped.
Vegetation & thermal
Vegetation shading rows, module and inverter temperatures, and the derates that heat brings on the worst afternoons.
Safety & DC arc-flash
Energized-string work, DC arc-flash boundaries, LOTO, and permit-to-work — logged against the block and the crew that touched it.
Soiling builds. A string trips. The crew cleans.
Performance ratio drops row by row as soiling builds toward the west, one string is flagged on fault, and a cleaning pass sweeps across to recover the yield — while the array keeps producing and the PR meter reads the live number.
What the day becomes on the dashboard
Two questions an operator asks first: are we hitting the forecast, and is something quietly eroding the yield.
Trend Divergence
PODIllustrative operating data. POD builds these from the O&M report you file — the metrics your plant actually captures.
The systems POD tracks across the array
Every subsystem that decides whether the plant hits its number today.
Inverters
Central or string inverters — uptime, derates, and trips. The single biggest lever on daily yield.
Trackers
Single-axis trackers — stow events, stuck rows, and the backtracking that keeps rows from shading each other.
Strings & modules
Offline strings, degraded modules, and combiner alarms — the granular faults SCADA flags and a report closes out.
Cleaning & vegetation
Cleaning crews and mowing cycles — the field work that recovers soiling loss and clears shading.
What a generic maintenance log silently drops
A generic CMMS captures the work order. Solar O&M needs the yield around it.
Solar O&M reporting questions
A solar PV O&M report is the daily operating record of a running solar farm: energy produced versus the P50 forecast, performance ratio, plant availability, soiling loss, inverter and string faults, and the corrective work orders behind them. It is the record an asset manager, a lender, and the O&M contractor all read.
