SmartShield™ technology – cleaning & protection in one step
Repellence is key to long-Term performance
Soiling rates vary widely by site, with industry‑recognised annual performance losses ranging from around 5% to over 50%, and higher in extreme environments.
As soiling accumulates, system performance becomes less predictable and output declines over time.
Lavee Solar’s SmartShield™ technology cleans panel surfaces and creates a hydrophobic, anti‑soiling surface protection effect, helping to slow the rate of re‑soiling and keep panels cleaner for longer.
By reducing soiling and limiting repeated intervention, SmartShield™ supports more consistent retained performance across a wide range of site conditions - without the use of water.
Keeping panels cleaner supports consistent generation
After cleaning with Lavee Solar, panels benefit from built‑in surface protection that helps slow the accumulation of dirt and airborne contamination.
Independent testing shows that SmartShield™‑treated panels retain cleaner surfaces for longer than untreated panels, reducing soiling‑related losses and supporting more consistent light transmittance.
Cleaner panels help stabilise output over time and protect long‑term asset value.
No Clean vs Water vs Lavee Solar
Scenario 1 - No cleaning (grey line): Soiling accumulates continuously, leading to compound losses and a steady decline in retained performance.
Scenario 2 - Water cleaning (blue line): Performance temporarily recovers after cleaning, but soiling returns rapidly and performance drift resumes between interventions.
Scenario 3 - Lavee Solar (orange line): Panels are cleaned and protected. SmartShield™ slows the rate of re‑soiling, helping panels stay cleaner for longer and retain more stable generating performance between planned cleans.
Harness protection. Support long-term value
With Lavee Solar, the economic case centres on preventing soiling losses rather than relying on reactive cleaning or added resources. Even in lower‑irradiance regions, modest per‑panel costs can help retain performance that would otherwise be lost over time.
Wherever a system is located, one reality holds - unmanaged soiling leads to avoidable performance drift and cost.

Simple 3-step application process
Equipment needed for manual cleaning
Simple 3-step manual process
STEP 1 — SPRAY
Apply approximately 50 ml of Lavee Solar evenly across the panel surface.
STEP 2 — SPREAD
Using a non-abrasive, non-woven synthetic cleaning pad, spread the product across the entire panel surface using straight, up‑and‑down strokes to lift and remove soiling.
STEP 3 — SQUEEGEE
Starting at the top of the panel, use a squeegee to remove the loosened soiling and excess product in straight downward strokes.

Semi & fully automated cleaning
Flexibility & compatibility
Lavee Solar works with a variety of application methods - manual, semi-automated (e.g. rotary brushes, air spray systems) and selected fully automated application techniques.
Because automated systems vary widely by manufacturer and configuration, we recommend contacting our team to discuss your specific automation requirements.
Testing, approvals & manufacturer compatibility
Lavee Solar is independently tested and designed for use in warranty‑sensitive PV environments.
Independent testing by TÜV SÜD and research conducted by UNICAMP confirm product safety, quality, and compatibility with normal solar panel operation.
In addition, Lavee Solar is approved for use by leading global PV module manufacturers, with ongoing engagement to ensure compatibility across a wide range of modern PV technologies and surface types.
Lavee Solar is working closely with a growing number of the world’s leading PV panel manufacturers. More to follow...
Recognised excellence in solar panel care
Protecting your investment for the long term
Investing in solar is a long‑term commitment that extends well beyond installation. With most leading PV manufacturers offering 15‑to 30‑year warranties, maintaining module condition and surface integrity is an important part of protecting asset value over the life of the system.
Lavee Solar is designed to support stable long‑term performance by reducing soiling‑related risk without compromising manufacturer warranty requirements.
Trusted safety where it matters
Manufacturers strongly advise against using untested or unsuitable detergents, as they can damage the glass, seals, frames and surrounding components.
Lavee Solar is engineered with safety at its core - formulated to protect every part of the installation while being safe for the environment and the people who maintain the system.
It cleans effectively without compromising the integrity of the hardware.
Tested, approved and trusted by experts
Lavee Solar has been independently tested by TÜV SÜD and UNICAMP, ensuring it meets strict standards for safety and performance.
It is also approved for use by leading global PV manufacturers, giving confidence that panels can be cleaned and protected without compromising materials or warranty requirements.
When you choose Lavee Solar, you’re choosing a solution that safeguards your investment and supports stable long‑term system performance.
