- Financial loss in your local currency (ZAR / USD / KES)
- Actionable O&M procedures — how to maintain your system
- Executive-level ready PDF for head of PMO or CFO
- IEC 61724 compliant — suitable for warranty / insurance claims

Sibaya Casino, Durban — 2.31MW rooftop
The engineering manager noticed a 16% gap between current and previous municipality readings — the energy use simply didn’t add up. The Energy At Risk report traced the variance to 4 of 7 inverters with hardware faults, calculated R8.8M in projected annual losses at eThekwini TOU tariff, and prioritised exactly which component to fix first.
The question was: “Is this variance acceptable?” The answer was an executive-level ready PDF showing precisely where the money was going.

Beyond passive monitoring. This is infrastructure for optimizing mini-grid dispatch, driving proactive maintenace, and gaining fine-grain control over performance ratio. Here’s what that shift looks like as a financial transaction:
Foregone generation credit
Every kilowatt-hour your inverters fail to produce is a solar credit you don’t earn. At R2.50/kWh, underproduction converts directly into lost revenue — calculated to the unit, invisible on your O&M report.
Grid replacement cost
Those same kilowatt-hours are purchased from the municipality at TOU rates. Effective all-in cost: R3.80–R4.60/kWh. During eThekwini winter peak (18:00–20:00), replacement cost exceeds R5.50/kWh.
Total loss per underproduced kWh
Credit not earned plus replacement cost paid. These two line items rarely appear on the same report. That’s why the actual cost of underperformance is almost always underestimated.
A performance ratio of 0.62 on a 2MW site at Durban irradiance levels represents roughly 900,000 kWh/year of underproduction against the IEC 0.80 baseline. At a combined loss rate of R6.30–R7.10 per kilowatt-hour, that gap costs R5.7M–R6.4M per year — or R17M–R19M over three years — split silently across two line items that most finance teams never reconcile against each other.
The Sibaya result exceeded this estimate: R8.8M in projected annual losses on a 2.31MW rooftop, traced to 4 of 7 inverters. The report cost $50.

Warranty and insurance recovery
Hardware faults that go unattributed don’t pause your equipment warranty window — they consume it. A fault running undetected for six months is six months of coverage expiring with no claim filed. The EAR Report produces the per-inverter fault classification and financial impact calculation required to initiate a warranty or insurance claim. IEC 61724-1 compliant. Suitable for submission to your OEM, insurer, or project lender.
What the subscription replaces
Per-meter anomaly monitoring runs at R200/meter/month. On a 7-inverter site, that’s R1,400/month — replacing a traditional O&M consultant, a monitoring platform, and the quarterly site visit. A single underperforming inverter costs R38,400 in a week undetected. Detection within days versus discovery on the next quarterly visit: that’s the financial case for the subscription.

Common questions
My meters don’t reconcile — is that what this solves?
Exactly. If there’s a gap between your solar generation meter, municipality meter, and site load, the EAR report decomposes that variance, attributes it to specific inverters, and puts a Rand figure on it.
How is the free forecast different from the EAR report?
The free forecast tells you what your system should produce tomorrow. The EAR report tells you why it has been underperforming over the past months, which inverters are responsible, and what the gap is costing you.
Can I show this to my GM or CFO?
That’s the point. The report is a boardroom-ready PDF with energy balance reconciliation, per-inverter attribution, and financial impact in your local currency. It also follows IEC 61724 methodology, so it’s suitable for warranty claims, lender reviews, or insurer assessments.
What data do I need?
A CSV export from your inverter portal covering at least 30 days (ideally 6–12 months), plus your site’s lat/long coordinates. We auto-detect the OEM format — no manual configuration needed.
How does per-meter monitoring work?
We connect to your inverter portal’s API and ingest 5-minute telemetry continuously. When an inverter deviates from expected output given actual weather conditions, you get an alert with the estimated financial impact — before a fault becomes a month of lost production.
Is there a discount for multiple sites?
Yes. For portfolio analysis (3+ sites), contact us for bundled pricing. Ongoing monitoring is priced per meter, so larger fleets benefit from proportional savings.
