 Note that in this example the Power (W) rating is 190, which is the Vmp x Imp (28.60 x 6.64 = 189.904W).  Note that in this example the Power (W) rating is 190, which is the Vmp x Imp (28.60 x 6.64 = 189.904W). 
  
-In real world conditions [[electrical:solar:output|power output will likely be less]] than under optimal lab conditions and the **Vmp may not be at 28.6v**.  Vmp will vary due to local conditions like temperature, shade, and sunshine.  An [[electrical:solar:charge_controller|MPPT charge controller]], if present, will sweep the range of voltages regularly to find Vmp under the existing conditions.+In real world conditions [[electrical:solar:output|power output will likely be less]] than under optimal lab conditions and the Vmp may not be at the voltage given on the label.  Vmp will vary due to local conditions like temperature, shade, and sunshine.  An [[electrical:solar:charge_controller|MPPT charge controller]], if present, will sweep the range of voltages regularly to find Vmp under the existing conditions.
  
 Panels will get closest to their rated output at ambient temperatures around 32f/0f when the panels will be running about 85F.  By the time ambient temperatures are 90F panel temps will rise to 145F and power output will drop about 18.45%.((http://digivation.com.au/solar/tempderate.php)) Panels will get closest to their rated output at ambient temperatures around 32f/0f when the panels will be running about 85F.  By the time ambient temperatures are 90F panel temps will rise to 145F and power output will drop about 18.45%.((http://digivation.com.au/solar/tempderate.php))
