Solar panel cleaning services

Specialist cleaning for every size of solar installation in Gauteng — delivered by a trained, ISCA-approved team that puts safety and your panels first.

Homes, townhouses and estates

Residential Solar Panel Cleaning

Careful, professional cleaning for home solar systems across Gauteng — so the panels you invested in can keep up with your household's energy needs.

Most home solar systems sit on the roof, out of sight — and quietly collect dust, leaves, pollen and bird droppings. Over the dry Highveld winter that film can build up quickly, and a short shower of rain rarely clears it.

Our trained team cleans your panels from the ground wherever possible using telescopic, water-fed poles and soft-bristle brushes. Where roof access is needed, we follow proper working-at-height procedures and treat your roof tiles, sheeting and property with care.

Why homeowners choose Solar Star

  • Visual check included — we'll tell you if we notice cracked glass, loose fittings, nests or shading issues.

Offices, retail, factories, warehouses

Commercial & Industrial Solar Cleaning

Reliable, safety-focused cleaning programmes for business rooftops, shopping centres, factories and warehouses — planned around your operations.

A commercial solar installation is a significant investment, and soiled panels can quietly erode its return. Industrial sites in particular — near roads, loading yards, production processes or open ground — often collect dust and residue faster than homes.

We work with facility managers, property owners and O&M contractors to plan cleaning that fits your site: agreed schedules, access arrangements, permit-to-work requirements and induction procedures.

How we work on commercial sites

  • Pre-work planning — scope, access, safety requirements and timing agreed upfront.
  • Site-specific safety — risk assessments, PPE, working-at-height controls and respect for electrical boundaries.
  • Minimal disruption — cleaning scheduled around trading hours and operations.
  • Completion reporting — confirmation of work done, plus any visible concerns noted during the clean.
  • Responsible water use — in line with your site's environmental requirements.

Relevant qualifications, safety documentation and compliance records can be provided on request for supplier registration and tenders.

Utility-scale and agricultural arrays

Solar Farm Cleaning

Planned cleaning programmes for utility-scale, agricultural and ground-mounted solar arrays — coordinated with your site and O&M teams.

Ground-mounted arrays on open land face dust, sand, agricultural residue and bird activity that can build up quickly between rains. Keeping rows clean is a routine part of protecting yield and asset condition.

Solar Star works with independent power producers, solar developers, O&M contractors and farms to deliver cleaning according to approved site procedures, scope and schedule — subject to site access, equipment requirements and project size.

What we bring to solar farm projects

  • Structured cleaning cycles — row-by-row cleaning to an agreed programme.
  • Site coordination — we work with site management and follow induction, access and electrical safety rules.
  • Reporting — completion status and any visible panel damage or concerns, reported through your channels.
  • Water and environmental responsibility — careful water management in line with site requirements.
  • Subcontracting — we're open to partnering with established O&M and EPC companies.

Clear gutters while we're on the roof

Gutter Cleaning

Blocked gutters overflow, stain walls and can cause leaks. While we're on the roof for your solar panels — or as a separate visit — we'll clear them out.

Leaves, seed pods, bird nests and roof grit collect in gutters all year round. When Gauteng's summer thunderstorms arrive, blocked gutters overflow — sending water down walls, into eaves and around foundations.

Because we already have the access equipment and trained team on site for solar panel cleaning, adding a gutter clean is a quick and cost-effective way to look after your whole roof in one visit.

Good to know

  • Best timing — just before the summer rains (around September to October) and again after autumn leaf-fall.
  • Combine and save time — one visit, one call-out, panels and gutters done together.
  • We'll tell you what we see — sagging sections, loose brackets or damaged downpipes are reported to you.

What's included

  • Removal of leaves, nests and debris from gutters
  • Clearing of downpipe entrances
  • Debris bagged and removed or left for disposal, as agreed
  • Visual check of gutters and brackets

Ideal for

  • Homes with trees near the roofline
  • Clients already booking solar panel cleaning
  • Townhouse complexes and estates
  • Commercial and industrial buildings

Streak-free glass, inside and out

Window Washing

Dusty Highveld winters leave windows as grimy as solar panels. We use the same careful, water-fed approach to leave your glass clear and streak-free.

Wind-blown dust, rain spots, cobwebs and fingerprints quickly dull windows, glass doors and balustrades. Clean glass lets in more light, improves your view and makes a great first impression on visitors and customers.

Because our team is already on site with water-fed poles, soft brushes and working-at-height equipment for your solar panels, adding a window wash is a simple and convenient way to freshen up the whole property in one visit.

Good to know

  • Reach without ladders: water-fed poles reach upper-storey windows safely from the ground in many cases.
  • Frames and sills included: we wipe down frames and sills, not just the glass.
  • Combine and save time: panels, gutters and windows in one visit, one call-out.

What's included

  • Exterior window glass cleaned
  • Interior glass on request
  • Frames and sills wiped down
  • Glass doors, balustrades and skylights
  • Upper storeys via water-fed poles where possible

Ideal for

  • Homes and double-storey houses
  • Clients already booking solar panel cleaning
  • Offices, shopfronts and showrooms
  • Townhouse complexes and estates
  • Move-in and move-out cleans

Once-off or scheduled cleaning

Choose a single deep clean for panels that haven't been cleaned in a while, after building work nearby, or before you sell your property. Or set up a scheduled maintenance plan based on your site conditions.

  • Once-off and deep cleans
  • Routine maintenance programmes
  • Post-construction dust removal
  • Visual inspection and feedback with every clean

Who we work with

  • Homeowners, estates and body corporates
  • Commercial property owners and managers
  • Factories, warehouses and distribution centres
  • Solar installers, O&M and EPC companies
  • Solar farms, IPPs and agricultural businesses
  • Schools, institutions and government (subject to procurement requirements)

Questions

Frequently asked questions

Why do solar panels need cleaning?

Dust, bird droppings, pollen, leaves and pollution settle on the glass and block some of the sunlight from reaching the solar cells. Removing that layer helps your system work as it was designed to.

How often should solar panels be cleaned in Gauteng?

For most homes, once or twice a year — ideally after the dry, dusty winter (around August to October). Sites near gravel roads, mines, farms, construction, industry or heavy bird activity may need more frequent cleaning. We'll recommend an interval for your site.

Doesn't the rain clean my panels?

Rain helps a little, but it usually doesn't remove bird droppings or baked-on grime, and it often leaves a line of dirt along the bottom edge of each panel.

How much more power will I get after cleaning?

It depends on how dirty the panels were, the weather, panel design and other factors, so we can't promise a specific increase. Heavily soiled panels typically benefit the most. If you have a monitoring app, you can compare output before and after.

Will cleaning damage or scratch my panels?

Not when it's done correctly. We use soft-bristle, water-fed brushes and panel-safe methods, and avoid abrasive pads, harsh chemicals and anything that could harm the glass, coatings, frames or seals.

Do you touch the electrical system?

No. We only clean the panel surfaces and frames, and respect electrical safety boundaries on every site. If we notice a potential problem, we'll tell you so a qualified electrician or installer can check it.

Are your staff trained?

Yes. Solar Star is ISCA approved (International Solar Cleaning Academy), and our staff are trained in correct solar cleaning methods, equipment handling, working at height and site safety.

Which areas do you serve?

All of Gauteng, including Johannesburg, Pretoria, Centurion, Midrand, Sandton, Fourways, the East Rand, the West Rand and the Vaal. For solar farms and large projects we can discuss sites further afield.

Do I need to be home during the clean?

Not necessarily. We need safe access to the property and the roof area, and ideally an outside tap. Many clients simply leave the gate code or have someone let us in.

Do I need to switch my system off?

We'll advise you on the day. In general we never open or touch electrical components — we only clean the panel surfaces and frames.

How much does residential solar panel cleaning cost?

Every home is different, so we quote based on the number of panels, roof height and pitch, access and how dirty the panels are. Request a free quote and we'll get back to you quickly.

Can you clean outside business hours?

Yes — where it's safe to do so, we can schedule cleaning for early mornings, weekends or quieter periods to avoid disrupting your operations.

Can you provide safety documentation for our site?

Yes. We can supply applicable risk assessments, safe work procedures, training records and other compliance documents, and we follow your site induction and permit-to-work process.

Do you offer maintenance contracts?

Yes. We can set up a recurring cleaning programme based on your site conditions, with regular completion reports.

Do you work outside Gauteng?

Our home base is Gauteng, but we are happy to discuss solar farm and larger commercial projects elsewhere in South Africa. Contact us with your site details.

Can you register as a supplier or subcontractor?

Yes. We welcome supplier registration, tender and subcontracting opportunities, and can provide our company and compliance documents on request.

Can I book gutter cleaning without solar panel cleaning?

Yes. Gutter cleaning can be booked on its own, or added to a solar panel clean for convenience.

How often should gutters be cleaned?

Usually once or twice a year — before the summer rains and after autumn. Homes surrounded by trees may need it more often.

Can I book window washing without solar panel cleaning?

Yes. Window washing can be booked on its own, or added to a solar panel or gutter clean for convenience.

Do you clean inside windows too?

Yes, on request. Let us know when you ask for a quote so we can plan access and time.
