Commercial solar systems are installed, commissioned, and then largely left alone. No one reads the monitoring data. No one checks the output. Output loss compounds quietly — and the asset sits on the books producing less than it should. WattNext changes that.
Most commercial operators know their system is on the roof. What they don't know is what it's actually producing — and what that gap is costing them.
Commercial rooftops accumulate soiling faster than residential — more exposure, more traffic, more industrial fallout. At 100kW, every percentage point of output loss is money leaving the business.
The asset sits on the books. Nobody can answer what it's actually producing. A maintenance history with documented output data is what turns a solar asset into a quantified investment.
String faults, inverter underperformance, shading issues — none of these stop the system. They just reduce output quietly. Without someone reviewing monitoring data, the same fault can cost thousands before anyone notices.
Commercial electricity tariffs are complex and change frequently. The tariff structure that made sense at installation may now be costing the business significantly. Most operators have never had this reviewed against their actual usage and self-consumption profile.
We come from 10 years in solar design. We understand inverters, monitoring data, and what a system should actually be producing. Most cleaning companies have never read a performance ratio.

| Electricity tariff review | Never | Included — identifies business savings |
| Nano-ceramic coating | No | Year 1 — reduces soiling rate |
| Solar industry background | No | 10+ years design & sales |
One contract covers three years of active solar performance management. Every visit produces a written report. Every year the asset has a documented maintenance history.
The first visit establishes the complete performance picture — current output, output baseline, monitoring status, fault history, and a written report suitable for the asset register or board reporting.
Each annual visit keeps the system at peak output and produces a documented record for the asset register.
For businesses that report on sustainability outcomes — monthly or quarterly clean energy data delivered ready to use.
We review your monitoring data remotely. No site visit, no obligation. We tell you the output gap and its dollar value.
Full clean, coating, monitoring audit, tariff review, performance baseline. Results delivered same day.
Before and after output, performance ratio, findings register. Formatted for asset register or board reporting.
Annual visits, mid-year monitoring check, tariff review. Three years of active management. One point of contact.
These are results from commercial customers across the Northern Rivers and South East Queensland.
"As a facilities manager I need documented proof that maintenance has been completed. WattNext gave us a proper written report with before and after figures — exactly what our asset register requires."
"They found a string fault that had been running for over a year. Nobody had picked it up. The monitoring setup they put in place has already caught two issues since. Completely changed how we manage this asset."
"The tariff review alone saved us more than the full first-year service cost. We had no idea the business was on the wrong plan. The solar background makes WattNext a completely different service to a standard cleaning company."
One program, everything included. Price varies by system size — that's the only difference.

Most commercial inverters have a web or app-based monitoring portal. We can work with any platform — SolarEdge, Fronius, Sungrow, Enphase, GoodWe, and others. If the monitoring hasn't been set up properly, we'll configure it on the first visit.
Before and after output in kW and kWh, performance ratio, dollar value of output recovered, findings register with priority grading, tariff review outcome, CO₂ offset data, and next service date. Everything needed for a formal asset maintenance record.
For systems requiring elevated work platform access, EWP hire is quoted separately and passed through at cost. We coordinate with your site manager to schedule access and minimise operational disruption.
Yes. Multi-site portfolios are quoted with a per-site discount. We produce a consolidated report across all sites and can align service dates to minimise management overhead.
We review your current electricity plan against your system's actual self-consumption profile, feed-in arrangements, and peak usage pattern. Commercial tariffs are significantly more complex than residential — the average saving we identify is around $1,200 per year.
No. We use pure water and a soft brush — the method specified as safe by all major panel manufacturers. High-pressure washing and chemical cleaners are what void warranties. Our method is fully compliant.
We review your monitoring data before we quote. No site visit required. No obligation. You get a written summary of the output gap and its dollar value — whether you work with us or not.
