Shared rooftop solar systems are frequently installed and then left alone. No one checks the output. No one reads the monitoring data. The committee hears nothing until something breaks — and by then, years of lost value are already gone.
A shared solar system operates in the background. No one's job is to watch it. Here's what's happening in the meantime.
Soiling builds up on flat and low-pitch strata rooftops faster than on residential arrays. The system looks operational but produces significantly less than it should.
The committee asks how the solar is performing. Nobody has an answer. There's no service record, no output data, no maintenance history. The asset sits on the books with no evidence it's being managed.
A string fault or inverter issue won't trigger an obvious alarm. Without someone reviewing the monitoring data, the same fault can cost the scheme money every day for a year or more before anyone notices.
When a shared system underperforms, every lot owner pays more for electricity than they should. Active management is the only way to protect what every owner contributes to.
We come from 10 years in solar design. We understand inverters, monitoring data, and what a system should actually be producing.
| What you get | Generic cleaner | WattNext |
|---|---|---|
| Panels cleaned | Yes | Yes — pure water, every panel |
| Before & after output measurement | Rarely | Every single visit |
| Written service report | Rarely | Same day, every visit |
| AGM-ready performance documentation | Never | Annual summary included |
| Monitoring platform review | Never | Fault alerts checked every visit |
| Performance ratio analysis | Never | Year 1 baseline + annual tracking |
| Electricity tariff review | Never | Included — identifies scheme savings |
| Nano-ceramic coating | No | Year 1 — reduces soiling rate |
| Solar industry background | No | 10+ years design & sales |
One committee resolution covers three years of active solar management. Every visit produces data. Every year the committee gets a written report ready to table at the AGM.
The first visit establishes the complete picture — system condition, actual output, monitoring status, and a baseline report suitable for the asset register.
Each annual visit keeps the system at peak output and gives the committee everything they need for the AGM.
For schemes that report on sustainability outcomes — monthly or quarterly data delivered ready to use in owner or tenant reports.
We review your monitoring data remotely and tell you what the system is producing vs what it should be. No site visit, no obligation.
Full clean, coating, monitoring audit, tariff review, baseline report. One day on site. Results delivered same day.
Before and after output, performance ratio, findings register, CO₂ data. Formatted for the AGM or asset register.
Annual visit, mid-year monitoring check, tariff review. Three years of active management. One point of contact.
Every job includes a written before and after measurement. These are results from real strata jobs across the Northern Rivers and South East Queensland.
"We had no idea the system was running at 73% of potential. After WattNext we had a performance report we could table at the AGM. First time in three years we could answer the committee's questions."
"The tariff review found us on the wrong plan. Switching saved the scheme more in year one than the full three-year program costs. The solar expertise is what makes this different."
"They found a string fault that had been running for over two years. First company that actually read the monitoring data. The committee was frustrated it wasn't caught earlier — but at least we know now."
One program, everything included. Price varies by system size — that's the only difference.

For most schemes, a maintenance service agreement sits within the strata manager's delegation or requires a simple majority resolution. We can provide a one-page summary suitable for the meeting agenda.
That's entirely up to the committee. Most schemes fund it through the admin or maintenance fund as a shared asset maintenance cost. We issue a single invoice to the scheme.
Before and after output readings, performance ratio, CO₂ offset, dollar value of output recovered, findings register with priority grading, tariff review outcome, and next service date.
Yes. Multi-building schemes are quoted on a portfolio basis and typically attract a discount. We can coordinate scheduling across buildings and produce a consolidated report for the committee.
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.
Typically two to three weeks. We work with building managers to arrange roof access and minimise disruption to residents. For large schemes we can stage the work across multiple days.
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.
