PV arrays are rated under standardized conditions such as specified illumination 1000 W m spectrum of the light Air Mass 1 5 standard reference spectrum and specified temperature 25 C that 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 A properly designed and installed PV system will produce less than its peak STC rated output Actual production depends on several unavoidable environmental factors described in this section PV array temperature affects the output of the entire system As the temperature on the array surface heats up its energy output goes down Roof mounted arrays also collect the heat generated by the roof surface or trapped under the array and will produce less output than pole mounted arrays which allow greater air circulation behind the panels Important The GT Inverter will reduce its energy output to protect its electronic circuits from overheating and possible damage in high heat conditions For maximum output in hot climates mount the GT Inverter in a shaded location with good air flow The angle of the sun in relation to the PV array surface the array orientation can dramatically affect the PV array output The array energy output will vary depending on the time of day and time of year as the sun s angle in relation to the array changes Incident sunlight decreases when the s
