Your meters don’t reconcile.
Find out why — and what it’s costing you.

When solar generation, municipality meters, and site load don’t add up, the gap is real money. We decompose the variance, attribute it to specific inverters, and give you a number your GM can act on.

From quick sanity check to ongoing accountability

Sibaya Casino, Durban — 2.31MW rooftop

The engineering manager noticed a 16% gap between expected and actual municipality consumption — the energy balance simply didn’t add up. The Energy At Risk report traced the variance to 4 of 7 inverters with hardware faults, quantified R8.8M in projected annual losses at eThekwini TOU rates, and prioritised exactly which units to fix first.

The question was: “Is this variance acceptable?” The answer was a boardroom-ready PDF showing precisely where the money was going.

How the EAR Report works

You provide the data your inverter portal already has. We turn it into the answer your finance team needs.

1

Export your inverter data

Download a CSV from your inverter portal (Huawei, Solarman, SolarEdge, Enphase, Fronius, etc.) covering at least 30 days. No special configuration — we auto-detect the format.

2

We reconcile the energy balance

Our pipeline cross-references your generation data against site-specific weather, decomposes the variance between meters, and attributes shortfalls to individual inverters — separating hardware faults from weather-driven gaps.

3

You get the answer in 48 hours

A boardroom-ready PDF showing the energy balance, per-inverter performance, root cause breakdown, and financial impact in your local currency — ready to hand to your GM, O&M provider, or EPC.

Supported inverter manufacturers

If your OEM is in the list, we can ingest your data. Auto-detected from CSV column names — no manual configuration needed.

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.
