Everything it takes to keep a solar plant clean.
We clean when it pays, remove what water can’t, fix the water, and match the equipment to your panels. At least one deep clean a year, and data deciding the rest.
A cleaning schedule engineered for your plant.
Most plants clean on a fixed calendar. We work out how fast each part of your plant gets dirty and what that costs, then set the frequency, method and products that give you the most energy for every rand spent.
Soiling survey
Drone and walk-down inspections, soiling sensors and reference strings show what is on the glass and how fast it builds.
Frequency model
We balance lost yield against the cost of each clean to find the interval that costs you least.
Method and products
Manual, tractor or robotic cleaning, plain water or a product for bonded dirt, chosen per block.
Method statements
Step-by-step procedures, safety files and quality checklists, ready for your site manager to sign off.
When water isn’t enough.
Cement and lime dust, hard-water scale, soot and baked-on droppings bond to the glass. We identify the contaminant, prove a product on a test patch, then treat, brush and rinse, using specialised chemicals from our chemical partners.
- Contaminant identified on site
- Test patch before any treatment
- Warranty-safe products and methods
- Optional anti-soiling protection
The right water, where the panels are.
Many large plants sit far from clean water, and hard or salty water leaves scale behind. With our water partners we design and run desalination and filtration systems that supply low-mineral cleaning water on site.
Water assessment
We test your borehole, municipal or trucked water and work out the volumes the programme needs.
Treatment design
Desalination, reverse osmosis, softening and filtration sized with our partners.
Storage
Tanks sized to the busiest week of the cleaning schedule.
Delivery
Bowsers and fill points placed so crews spend their time cleaning, not driving.
Less water per clean
Methods and products that use less water, and reuse where the site allows it.
Crews that get every row up to standard.
Our field teams are trained to clean solar plants safely and without damaging modules. They work to the programme, record every row and hand over a signed-off quality check.
- Solar-specific induction and training
- Method statement and safety file on every site
- Every row cleaned is logged
Utility-scale ground mounts
Fixed-tilt and tracker rows, cleaned by tractor-mounted brushes, robots or crews.
Large C&I rooftops
Factory, warehouse and mall roofs, cleaned under a working-at-heights plan.
Restoration cleans
A deep first clean to bring a neglected plant back to standard before routine cleaning starts.
Flexible contracts
Once-off, seasonal or full-year programmes, priced per MWp per clean.
Data that keeps the schedule honest.
A schedule set once goes out of date as the seasons change. We track soiling and performance before and after every clean, and move cleans earlier or later when the numbers say so.
Soiling sensors
Sensors or clean reference strings that measure soiling loss every day.
Before and after checks
Performance compared across each clean, so you see what it delivered.
Monthly reporting
Energy recovered, water used, rows cleaned and any defects found.
Defect spotting
Cracked glass, hot spots and loose cables flagged for your O&M team.
The right equipment for your panels.
We are equipment specialists. We match the cleaning method to your panels, rows and terrain, and automate wherever we can to remove human error and finish faster.
Robots clean by themselves
Robots clean your plant on their own. RenewChem can supply them, and we set them up and service them.
People with machines
Our people working with robots and vehicle-mounted brushes for long ground-mount rows.
Trained crews
Trained crews where the site doesn’t allow machines: rooftops, tight rows and spot cleans.
At least one deep clean a year.
Heavily contaminated sites may need more than one. Between deep cleans, we can clean all year, or your team can.
1 · Full clean
Every panel on the plant, cleaned thoroughly.
2 · Remove scale and contaminants
Specialist chemicals take off hard-water limescale completely.
3 · Protect
An anti-static coating slows dust build-up and stops scale binding again.
Then: clean when it pays
Sensors and AI time every clean in between to your target return.
Why chemical cleaning stays with us
The wrong dilution ratio wastes chemicals and money, and can damage your panels. Specialist chemical cleaning is done only by our trained, certified crews. That keeps one source of responsibility for the result.
We work alongside your O&M team, not instead of it.
Full turnkey
We handle all cleaning, testing and reporting, all year. Ideal for sites with few O&M staff, so they can focus on what matters.
Shared
We do the deep cleans and chemical work. Your team does routine cleans, grass and fire breaks, and equipment.
Monitor and advise
We watch the data, point your team to underperforming areas and train your staff.
Not sure which service you need?
We’ll measure your soiling, check your water and recommend a programme that fits your plant and budget.
