Expert-supervised comparison
Reported average energy advantage of coated strings over untreated comparison strings.
05 / FIELD RESULTS
Real installations.
Real results.
What matters is performance in everyday operation: on real solar installations, in real weather, over time.
BEYOND THE LABORATORY
Field results show what happens on your panels.
Laboratory tests explain mechanisms. Field comparisons show performance under rain, dust, organic deposits and actual operating conditions. Both are useful; practical results are central to our project discussions.
REPORTED PROJECT RESULTS

Real results.
Agricultural installation
Reported production comparison between two systems, one coated and one uncoated.
Brazil: maximum string increase
Maximum reported increase for an individual string after 3 months; not the average for the entire installation.
These figures come from the supplied project summaries. Different sites and test methods are not directly comparable, and no percentage is a guaranteed result for a new installation.

Brazil: string measurements
The supplied comparison lists before-and-after string measurements after 1 and 3 months, with a maximum reported increase of 23.68% after 3 months.

Customer power comparison: +8.3%
The sheet dated 22 April 2025 reports 8.3% higher measured power for the coated comparison. This is a power measurement, not an annual energy-yield figure.

One year later: surface comparison
All modules were cleaned at the start. The sheet contrasts the coated side with the side that was cleaned only, one year later.

Philippines: included in proposals
Customer feedback from Grace describes including CERACOAT as a standard part of solar proposals and their cost calculation.

Compare fairly.
Learn before you scale.
Choose comparable modules
Select coated and uncoated sections with similar orientation, tilt, shading and operating conditions.
Record a baseline
Clean both sections at the start. Record module details, coating date, weather and the measurement approach.
Track the outcome
Follow production, rainfall and visible soiling over time. Keep regular photos and note maintenance events.
Separate appearance from energy data.
Photos can document surface condition. Production measurements answer a different question: how much energy did each comparable section produce over the same period?
For an informative pilot, account for irradiance, temperature, downtime and other differences between systems. CERACOAT can help discuss the trial scope and reporting approach.
How quickly should we assess the coating?
Allow approximately two weeks for sunlight activation. The evaluation period should include representative soiling and rainfall conditions rather than relying on a single-day comparison.
Will our installation achieve the same result?
Energy gains depend on the site and its existing soiling losses. A cleaner installation with little soiling may show a smaller benefit than a heavily affected site.
