Effect on a solar plant facing foundry dust

Located in an industrial area, this three-year-old plant faced very heavy foundry dust, forcing weekly cleaning with heavy water and labour usage.

After applying the Solar Glass Shield coating, dusting reduced, generation improved by 3%, the cleaning cycle stretched to 30 days, and water, labour and costs fell dramatically.
