A 6MW textile mill in Maharashtra was choking on hard-water scale from its cleaning regime. The very water being used to wash the modules was depositing mineral scale that compounded the soiling problem it was meant to solve.
The challenge
Standard cleaning was leaving behind a white mineral film that grew thicker with every cycle. The scale diffused sunlight and accelerated soiling, steadily reducing output despite the mill’s regular maintenance schedule.
Our approach
SolarTrust switched the site to demineralised water and industry-grade chemical washing, removing the existing scale and preventing new deposits from forming. The corrected regime restored optical clarity to the module glass.
Results delivered
- Permanent 12% rise in energy output.
- Hard-water scale removed without damaging module glass.
- A sustainable cleaning regime the mill can maintain.
