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.
Third party field testing at PVEL showed up to 15% reduction in operating temperatures of inverters with shade covers
installed in direct sunlight.
If the Yaskawa Solectria Solar PVI 25TL-480-R is to be mounted at any angle lower than 75° from horizontal, a shade
cover is required.
