Installation and Operation Guide SOLECTRIA PVI 25TL-480-R Shade covers provide added protection for inverters against harsh environmental conditions like direct sunlight, snow, sleet, ice, hail, and reduce soiling from dust and birds. Depending on the application and environment, shade covers will help to increase energy production by reducing potential power derating due to excessive ambient temperatures. Inverters de-rate in extreme temperatures to protect themselves from over-temperature conditions.
