Effect on a solar plant facing soiling & road dust

Sited right next to the Mumbai–Agra National Highway, this four-year-old plant faced very high road dust and soiling, forcing weekly cleaning with heavy water and labour usage.

After applying the Solar Glass Shield coating, soiling reduced, generation improved by 9%, the cleaning cycle stretched to once every 6 weeks, and water, labour and costs fell dramatically.
