Residential solar maintenance

Your panels areprobably losing20% output.

Dust, pollen, and grime build up on your panels every season. Your system looks fine — but it's quietly generating less than you're paying for. We prove exactly what it's losing, then fix it.

The problem with unserviced panels

Your system works — but not as hard as it should.

Most homeowners assume if the system is producing something, it's fine. It isn't. Here's what's happening in the background.

01
Silent loss

Output drops without any warning

Dust, pollen, bird droppings, and airborne grime build up on your panels continuously. There's no alert. The system keeps producing — just less and less, every season.

02
No proof

You have no way to know what you're losing

Your inverter shows kWh produced — not kWh lost. Without a before and after measurement, you can't know the difference. Most homeowners have never seen their actual performance ratio.

03
Wrong tariff

You might be on the wrong electricity plan

Feed-in tariffs and usage rates change constantly. The plan that was optimal when your system was installed may now be costing you money. Most households have never had this reviewed.

04
Undetected faults

Faults go unnoticed without active monitoring

A failed string or inverter issue won't stop your system completely — it just reduces output quietly. Without someone reading your monitoring data, these faults can run for months.

The WattNext SolarShield Program

Three years. Everything documented.

A three-year residential solar maintenance program covering cleaning, monitoring, health audits, and tariff reviews — with written results on every visit.

Year 1 — Foundation visit

The Full Setup Service

The first visit does everything — cleans the panels, establishes your output baseline, reviews your monitoring setup, checks your tariff, and delivers a written performance report you can keep for your records.

  • Full array pure water soft-wash clean
  • Nano-ceramic coating application — reduces soiling rate
  • Before and after output measurement — written same day
  • Performance ratio baseline established
  • Monitoring platform review — fault alerts checked
  • Electricity tariff review — savings identified
  • Findings register — advisory, recommended, urgent items
Years 2 & 3 — Annual service

Annual Health Check

Each annual visit keeps your system at peak output and documents the result so you always know what your investment is delivering.

  • Full pure water soft-wash — every panel
  • Before and after output measurement
  • Annual performance report
  • Tariff review — is your plan still optimal?
  • Mid-year monitoring check-in between visits
Included every visit

Always in the Service

These aren't add-ons. They're included because they're the difference between a clean and a performance service.

  • Written before and after output report
  • Performance ratio vs design expectation
  • Electricity tariff review
  • Findings register with priority grading
  • Same-day delivery of results
How it works

From first contact to written results

01

Free assessment

We check your monitoring data remotely and tell you what your system is producing vs what it should be. No obligation.

02

Measure before

On the day, we record actual output before cleaning. This is the number that proves what soiling was costing you.

03

Clean & coat

Pure water soft-wash across every panel. Nano-ceramic coating in year one. Monitoring and tariff review included.

04

Written report

Before and after output, performance ratio, dollar value recovered, and any findings. Delivered same day.

Proof you can keep

A written report on the day

Every visit produces a document you can actually use — not just a text saying the job's done. Before and after output, dollar value recovered, system health findings, and tariff review outcome.

Output recovered — 6.6kW system, Paddington Brisbane

"I assumed the panels were fine because the bill had gone down since installation. Turned out they were running at 79% of what they should be. The written report was exactly what I needed."

"They found we were on completely the wrong electricity plan. Fixing that saved us more in the first year than the service cost. I didn't even know that was part of what they did."

Questions homeowners ask

Answers before you book

How often should I have my panels cleaned?

In the Northern Rivers and South East Queensland, once a year is typically sufficient for most residential systems. Proximity to roads, trees, or birds can increase the soiling rate and may warrant more frequent visits — we'll tell you after the first service.

Will cleaning void my panel warranty?

No. We use pure water and a soft brush system — the method specified as safe by all major panel manufacturers. High-pressure washers and chemical cleaners are what void warranties. Our method is fully manufacturer-compliant.

What does the before and after measurement actually tell me?

It tells you exactly how much output soiling was costing you, in kW and in dollars. Most homeowners have never seen this number — and are surprised by how significant it is.

What if you find a fault?

We document it in the findings register with a priority grading — advisory, recommended, or urgent. We don't do repairs ourselves but we'll tell you exactly what's wrong, what it's likely costing you, and who to call.

What is the tariff review?

We review your current electricity plan against your system's output profile and usage pattern. If there's a better option available — a higher feed-in tariff, a better usage rate, or a different retailer — we'll flag it. The average saving we identify is around 80 per year.

Do I need to be home?

No. As long as we have safe roof access, you don't need to be present. We'll leave the written report in your letterbox or email it the same day.
