Lavee Solar reduces soiling-related risk and operational dependency compared with traditional cleaning approaches, including water cleaning, detergent cleaning and waterless robots.

No Cleaning: No immediate effort, but leads to significant long-term performance loss and increased asset risk.

Water Cleaning: High logistical burden, heavy water use and risks such as micro-cracking, mineral residue and ingress.

Water + Detergent: Adds chemical handling, waste water concerns and potential warranty exposure.

Waterless Robots: High capital and operating costs, abrasion risk over time and no surface protection.

Lavee Solar: Waterless cleaning with built-in surface protection, minimal liquid use, lower operational complexity and approvals from leading global PV manufacturers.

Waterless cleaning is highly effective at removing dust and debris, especially when performed regularly. Lavee Solar has been proven to keep panels cleaner for longer due to its dirt and water repellent properties.

• Water conservation: Waterless cleaning is especially valuable in regions facing water scarcity or drought, where water-based cleaning can strain limited resources.
• Accessibility: Waterless methods are practical for panels installed in hard-to-reach or remote locations where water supply is limitedorlogisticsare challenging.
• Speed and efficiency: Faster application with minimal setup simplifies the cleaning process.

Yes, Lavee Solar can be applied during installation. Applying it at the point of installation helps protect panel surfaces from the outset, with SmartShield™ technology repelling dust and water and reducing early soiling. This supports more consistent initial performance and helps keep panels cleaner for longer, reducing the need for early intervention as the system enters operation.

No. Lavee Solar is approved by many leading panel manufacturers. Always check your panel’s warranty terms and recommended maintenance procedures before cleaning.

Yes. Lavee Solar is biodegradable, eco-friendly, pH-balanced, free from wax, silicone & heavy solvents – safe for use in all locations.

Yes. Many believe that frequent rainfall eliminates the need for solar panel cleaning, but this is a misconception. While rain can wash away loose dust, it does not remove sticky residues, bird droppings, pollen or mineral deposits. Over time, panels still accumulate layered soiling, which affects performance regardless of climate. Although soiling is typically more severe in dry, dusty environments, case studies from regions with high annual rainfall show that removing accumulated soiling can restore lost performance.

No. It is often assumed that solar panel cleaning and protection are only necessary during sunnier months, but this is not the case. To reduce soiling-related performance loss and make better use of available irradiance, panels should also be maintained during less sunny seasons such as autumn and winter. Dirt, debris and organic matter can accumulate year-round, affecting panel condition and performance even when sunlight levels are lower.

Soiling is the second biggest factor reducing solar performance after irradiance. Depending on environment, annual losses can range from around 5% in open spaces to 30% in agricultural or industrial areas and up to 50% in extreme environments. Even in Northern Europe, despite frequent rainfall, real-world soiling losses average 5–15%, as rain does not remove sticky residues, pollution, bird droppings or hard mineral deposits. Independent research from IEA PVPS, SolarAnywhere and European groups such as the German Aerospace Centre shows that rainfall typically removes only around 10% of soiling, with UK baseline losses of approximately 5.3% under modelled conditions. Combined with real-world factors such as pollen, tilt angle and seasonal accumulation, regular cleaning is important to limit soiling-related performance loss over time.

Yes. Ignoring soiling over time introduces avoidable performance loss that compounds year after year. In high‑soiling environments, unmanaged panels can lose a significant proportion of their annual output. Even in lower‑soiling regions such as the UK, soiling‑related losses accumulate if not addressed. When relative cleaning costs are compared with the value of retained performance over time, preventive cleaning is often economically justified. The value comes from preventing long-term performance erosion rather than chasing short term yield uplift.

Lavee Solar works using a simple 3-step process (Spray-Spread-Squeegee) that mixes and binds Lavee Solar with any soiling (dust, dirt, etc.), and then removes the mixture from the panel. All without needing an on-site water supply. Plus, it leaves behind a SmartShield coating that repels dust and water, keeping panels cleaner for longer.

SmartShield™ technology delivers an advanced dual-action surface treatment that cleans the panel surface and provides a hydrophobic, anti-soiling surface protection effect. This protection reduces dust, dirt and water retention, slowing the rate of re-soiling. By helping panels stay cleaner for longer and supporting consistent light transmittance, SmartShield supports more stable real-world performance over time, with outcomes varying by site conditions and soiling rates.

Both work. DIY waterless cleaning is possible for ground-mounted or easily accessible panels using proper tools, although we highly recommend following our ‘User guide’ for further details on equipment and application. For roof-mounted panels or large installations, professional services are safer and more efficient.

No. The product is ready to use and does not require any water at any stage (before, during or after).

The frequency depends on local conditions. In dusty environments or areas with little rainfall, more frequent cleaning can help limit soiling‑related performance loss. Planned schedules (such as monthly or quarterly) are common where soiling rates are high. In Northern Europe, where irradiance is relatively low and rainfall is prevalent, cleaning once or twice per year is typically sufficient as part of a planned maintenance approach.

Ideally clean when panels are cool - early morning, late afternoon, or overcast days. If cleaning during hot period is necessary, more Lavee Solar may need to be applied due to evaporation.

Avoid cleaning during heavy rain, as it can dilute the product. Light rain is generally fine and won’t affect performance.

Yes, although very heavily soiled panels (e.g. tree sap, cement, encrusted dirt) may need multiple applications. Once cleaned and protected, future maintenance is faster and easier.
