Recover Lost Yield.
Share the Upside.
Curax applies a proprietary hydrophobic nanocoating to solar PV panels and wind turbine blades, delivering validated yield uplift of 5–15% on solar and approximately 7% on wind. Zero upfront cost. Profit-split on incremental revenue only.
Solar and wind assets are leaving revenue on the table — every day
Across global renewables portfolios, performance degradation is treated as an inevitable cost of ownership. It isn't. The losses are recoverable — and asset owners operating without a proven remedy are compounding them year after year.
Progressive Solar Yield Degradation
Solar panels lose 0.5–0.8% output annually through soiling, micro-cracks, and UV stress. In dusty, industrial, or arid environments, cumulative losses exceed 30% — silently eroding revenue on assets modelled against nameplate capacity at commissioning.
Wind Turbine Icing & Drag Losses
Ice formation on turbine blades distorts aerodynamic profile, increases drag, and forces automatic shutdowns. Research shows icing can cause over 20% annual energy production loss at affected sites. Even without icing, microscopic blade roughness continuously reduces yield.
No Capital-Light Remedy Has Existed
Conventional responses — periodic cleaning, blade erosion treatments, active heating systems — are costly, operationally disruptive, and provide only temporary relief. Asset owners have lacked a durable, zero-capex intervention that works continuously.
Three optical mechanisms. One application.
The Curax nanocoating creates a permanent molecular bond with panel glass, operating through three validated physical mechanisms to recover and enhance light capture.
Hydrophobic Self-Cleaning (Lotus Effect)
Ultra-high water contact angle (150°+) causes rain to bead and roll, carrying particulate contamination off the surface. Soiling accumulation between cleaning cycles is dramatically reduced, preserving rated output continuously.
Graded Refractive Index Anti-Reflection
The nanoscale coating creates a graduated transition between air and glass, reducing surface reflectance. More incident photons reach the active semiconductor layer, improving conversion efficiency at all irradiance levels.
Low-Angle Forward Scattering
Nanoscale surface topology redirects incident light at shallow angles toward the cell surface, generating meaningful uplift during morning, evening, and diffuse-light periods — particularly relevant in northern European climates.
More output. Fewer shutdowns. Same turbines.
The same coating applied to wind turbine blades delivers two compounding benefits: reduced aerodynamic drag year-round, and passive ice resistance that keeps turbines generating through cold weather events that would otherwise force shutdowns.
Reduced Aerodynamic Drag
Turbine blades generate lift in the same way as aircraft wings — the smoother the surface, the less turbulent drag and the more efficiently wind converts to rotation. The nanocoating fills microscopic surface imperfections, reducing boundary layer turbulence across the full blade span. Lab trials demonstrate approximately 7% improvement in energy output.
Passive Ice Resistance
Ice accretion distorts blade aerodynamics, creates rotor imbalance, and triggers automatic safety shutdowns. The coating's 150°+ water contact angle causes moisture to bead and shed before it can freeze on the blade surface, requiring no power or active heating system. Research shows icing causes over 20% annual energy loss at affected sites.
149 MW. Six sites. Six quarters of data.
Performance compared against a multi-year pre-coating baseline, adjusted for 0.7–0.8% annual degradation. Environmental factors not isolated. All sites remain positive across the full measurement period.
| Site | Capacity | Average Uplift (Total Period) |
|---|---|---|
| Site 1 | 21 MW | +7.7% |
| Site 2 | 14 MW | +7.2% |
| Site 3 | 20 MW | +7.3% |
| Site 4 | 45 MW | +6.4% |
| Site 5 | 24 MW | +14.1% |
| Site 6 | 25 MW | +7.7% |
| Weighted Average | 149 MW | +7.9% |
Performance measured over six quarters against a degradation-adjusted baseline. Periods of extreme weather temporarily suppressed observed uplift — all negative quarterly variances are environmental in origin. The coating cannot reduce photovoltaic performance.
Range 11.6%–16.3%. Consistently strong across all months. High-soiling, dusty environment — where the lotus-effect self-cleaning mechanism delivers maximum benefit.
Range 6.4%–19.2%. High early performance. Environmental factors isolated vs clean control panels, enabling direct attribution of uplift to the coating.
Range 3.8%–5.2%. Most stable site. Largest absolute energy gain due to installation scale. Demonstrates consistent floor-level performance in cleaner conditions.
Zero upfront cost. Share only the gain.
Curax's profit-split model removes every barrier to adoption. Asset owners bear no capex, no installation cost, and no performance risk — Curax is compensated only on proven incremental revenue.
Free Pilot Trial
Every asset owner receives a site-specific trial at no cost. Uplift is measured against clean control panels under identical environmental conditions to establish a verified baseline before any commercial agreement is signed.
Commercial Agreement — Profit-Split
Curax applies the coating across the agreed portfolio. The default structure is a profit-split: 50–60% of incremental revenue (electricity, carbon credits, cleaning cost savings) flows to Curax. Zero upfront cost to the operator.
Ongoing Monitoring & Insurance-Backed Guarantee
Curax provides continuous performance monitoring and optimisation throughout the contract term. Performance is backed by insurance, eliminating residual risk for the asset owner.
Maximise what your solar assets can earn.
For solar asset owners exploring Battery Energy Storage System integration, Curax can facilitate introductions to financing partners and advisory specialists. Co-located BESS transforms a solar site from a generation asset into a dispatchable one — unlocking revenue streams that the panel coating alone cannot capture.
Energy Arbitrage & Time-Shifting
Store excess generation during peak solar hours — when wholesale prices are typically low — and dispatch it during evening demand peaks when prices are highest. Co-located BESS on an existing grid connection avoids new interconnect costs and streamlines permitting.
Ancillary Services & Revenue Stacking
BESS can participate in frequency regulation, capacity reserve, and demand response markets simultaneously. Stacking revenues across energy, ancillary, and grid flexibility services on a single asset significantly improves project economics and bankability.
Curtailment Recovery
In regions with high solar penetration, grid curtailment wastes generation already optimised by the Curax coating. BESS captures that excess energy rather than losing it, ensuring the full benefit of yield uplift is monetised rather than clipped by grid constraints.
