Solar and wind plants are built to produce. We keep them that way.
RenewClean is the execution company of the RenewHoldings group. We are a Level 2 B-BBEE company that cleans, tests, monitors and maintains solar plants and wind turbines, with one point of contact and one full report.
Across South Africa, well-built plants lose output to dirt, scale and faults nobody has found yet. We started RenewClean to bring science to a job that is usually done by the calendar, and to make sure every rand spent on a plant comes back.
Not just another cleaning contractor.
Most cleaners sell labour by the hour. We sell clean, productive panels, and we prove it with data.
| Typical cleaning contractor | RenewClean | |
|---|---|---|
| When to clean | Fixed calendar | Triggered by measured soiling, per block |
| Bonded dirt | Scrub harder or ignore it | Identified, tested and removed with specialist chemistry |
| Water | Whatever is on site | Softened, RO or desalinated so it dries spotless |
| Equipment | Hoses and brushes | Robots, tractor brushes, rotary systems and crews |
| Proof | An invoice | Before and after data, energy recovered, monthly report |
| Faults | Not their job | Drone and handheld thermography, IV curve tests, fixed and proved |
| Credentials | Varies | Level 2 B-BBEE, SAPVIA member, ECSA-registered engineers, OHS Act safety file |
Four rules for every site.
Every programme and every crew follows them.
01Measure firstData before decisions
Every schedule starts with data from your plant.
02Protect the assetWarranty-safe, always
Methods and products that respect module warranties.
03Respect waterOnly what the job needs
The right quality, and as little as possible.
04Invest in peopleLocal, trained, safe
Local crews, trained and kept safe on every site.
Two RenewHoldings companies, one team.
RenewChem brings the science: chemistry, ratios, equipment and water advice. RenewClean does the work on site. Use RenewChem on its own, or let RenewClean deliver it all.
- Tailors chemicals and ratios to each site
- Supplies the cleaning chemicals, including foam for cleaning drones
- Supplies cleaning equipment, including robotic cleaners
- Tests water hardness and advises on treatment
- Cleans with trained crews, vehicles and robots
- Tests IV curves and runs drone and handheld thermography
- Monitors soiling to time every clean
- Maintains the plant, from inverters to trackers
- Cleans wind turbine blades by drone
Better pricing
One combined quote costs less than two separate contracts.
One point of responsibility
One team accountable for the result.
Built to work together
Chemistry, water and cleaning planned as one system.
Where an upgrade needs design and construction, such as lightning protection, we arrange it through our engineering partners.
