9.2 Shade Cover (SSC-60ST)
9.2.1 Protection from Harsh Conditions
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. When installing the inverter at tilts
of 75° or less from horizontal the shade cover is required.
9.2.2 Increased Energy Production
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 derate in extreme
temperatures to protect themselves from over temperature conditions.
Field testing at PVEL showed up to 15% reduction in operating
temperatures of inverters with shade covers installed in direct sunlight.
This report can be found on the CPS America website under application
notes.
