Factors Affecting Sun Tie XR Performance

This section describes several factors that will affect the amount of power that a properly installed and operating Sun Tie XR can produce.

PV Array Factors

PV array ratings

PV arrays are rated at ideal factory conditions, such as specified

 

illumination (1000 W/m2), spectrum of the light and specified

 

temperature (25 °C/77 °F), which seldom reflect real-world installations.

 

This is called the STC (Standard Test Condition) rating and is the figure

 

that appears on the PV module nameplate label.

Expected

Because of several unavoidable environmental factors, you can expect

performance

your PV array to produce around 60% to 70% of its peak STC-rated

 

output for a properly designed and installed PV system.
