Why choose this product range
Over 25 years of development experience — research continues today
Korea Total Service continues researching products and application processes, drawing on more than 25 years of development experience. Customer requirements are our starting point: we connect soil sources, materials and actual working conditions when developing product specifications.
Product-specific technical priorities
Solar cleaning considers soil removal together with optical and surface conditions. Dust, pollen and bonded soil are distinguished; glass, AR coatings, frames, seals and rinse residue guide separately specified cleaning and protection conditions.
Materials and process together
We assess surface changes, recovery, rinsing, drying and follow-up care alongside cleaning objectives to propose usable field methods.
Custom development and improvement
Manufacture after order is our basic policy, including general-purpose products. Customer requirements and application feedback inform subsequent specifications.
From customer requirements to product specifications
- Review photos, materials, contamination, operating conditions and objectives
- Select product and process options; discuss samples or spot trials when needed
- Manufacture and supply to agreed specifications, with application guidance
- Review outcomes and maintenance records to discuss improvements
Final ingredients, instructions, SDS and performance documentation are provided for the agreed product specification. These are development and selection criteria, not quantified guarantees of identical outcomes in every condition.
01 · Cleaning
Inspect dust, pollen, bird droppings and oily contamination on front glass. Remove soiling under approved conditions to reduce obstruction of incoming light and recover soiling-related energy losses.
02 · Protection care
Use non-abrasive tools, compatible chemistry, rinsing and residue checks to reduce damage risk to existing glass and anti-reflective coatings. New protective-film performance, durability and warranty compatibility require testing and approval.
Uncleaned versus properly cleaned
| Check | Uncleaned condition | Expected change after compatible cleaning |
|---|---|---|
| Optical soiling | Dust and pollen may obstruct light. | Remove contamination obstructing light transmission. |
| Localized shading | Droppings and leaves may shade cells. | Remove obstructions and inspect; cleaning does not repair hot spots or damaged cells. |
| Energy yield | Site-specific soiling may reduce energy production. | Some soiling losses may be recovered; rated module output is not increased. |
| Surface care | Contamination requires assessment. | Gentle cleaning, rinsing and checks of glass, coating, frames and seals. |
| Residue | Check existing deposits. | Check that detergent or hard-water residue has not left new marks. |
Verify cleaning effects through energy data
IEA PVPS’s September 2025 fact sheet describes average global soiling-related energy losses of 4–7%. This industry estimate does not guarantee a product-specific cleaning gain. Field observations and modeled scenarios are distinguished below.
How to assess results
- Record contamination, energy, irradiance, module temperature, rainfall and operating status.
- Use a comparable control area where possible and correct for irradiance and temperature.
- Inspect residue, seals, drainage and anomalies; qualified personnel can perform further diagnostics.
- Account for shading, inverter limits and equipment faults rather than comparing one day’s energy alone.
Cleaning and protection workflow
- Check module model, coating, warranty and manufacturer approval. Inspect damaged modules or electrical faults first.
- Work when modules are cool. Site personnel determine electrical isolation and fall-protection procedures.
- Test a small area. Follow finalized product labels, SDS and module instructions for dilution and contact time.
- Use non-abrasive tools and approved water quality/pressure. Do not walk on modules or spray wiring and junction boxes.
- Check dried surfaces for residue and coating changes; document photos and energy data.
Optional surface-protection treatment
Water-repellent or anti-soiling films require module-specific approval. Assess optical transmission, reflection, AR-coating compatibility, adhesion, weathering, re-soiling and warranty terms. A blanket coating or permanent no-cleaning claim is not offered.
Questions
Does rain replace cleaning?
Rain and tilt can remove some soiling. Inspection determines the need and economic value of cleaning.
How many panels per jerrycan?
Coverage requires finalized fill volume, dilution, application rate and contamination assessment.
Is protection a separate coating?
Basic care protects existing surfaces during cleaning. Additional films require separate compatibility tests and approval.
